How can a charged balloon attract a wall without any contact?
The positive charges of the uncharged wall move to the outside.
The wall changes shape and the positive charges move to the inside.
The negatively charged balloon repels and moves away from the wall.
A positive charge in the balloon attracts the negative charges in the wall
Answer:
A positive charge in the balloon attracts the negative charges in the wall
Explanation:
The question states attract, so we know it's not going to be option C.
The wall clearly doesn't change shape, so that eliminates option B as well.
The balloon gets positively charged, and so for an attractive force to appear, you need the opposite charge from the wall, i.e. negative.
Remember: opposite charges attract
Which means, the only option that makes sense is Option D.
P.S.: You could've concluded it's option D just because it's the only one that contains the word "attract" in there!
Hope I helped! :)
Answer:
a positive charge in the ballon attract the negative charge of the wall

1. When you dissolve an covalent compound in water, the solution does not conduct electricity.
2. Covalent compounds often have lower melting points than ionic compounds.
3. When you dissolve an covalent compound in water, the solution conducts electricity.
4. Covalent compounds form when combining two or more nonmetal atoms.
5. Covalent compounds form when combining a two metal atoms.
6. Covalent compounds form when combining a metal atom with a nonmetal atom.
The properties of covalent compounds are option 2, 3 and 4. Covalent bonds are weaker than ionic bonds.
What are covalent bonds?Covalent bonds are formed by sharing electrons between two atoms. Non metals with comparable electronegativities forms covalent bonds. They are weaker than ionic bond. Thus have lower melting point.
Melting point depends on the bond strength that's why covalent compounds have lower melting point compared with ionic bonds.
Polar covalent bonds can conduct electricity when dissolved in water because of the presence of free electrons. Thus option 3 is correct.
Hence, the properties in option 2, 3 and 4 are correct for covalent compounds.

calculate the mass required to prepare 2.5 L of 1.0 M NaOH solution. Given that the molar mass for NaOH is 40 g/mol.
Answer:
The required mass to prepare 2.5 L of 1.0 M NaOH solution is 100 g
Explanation:
We do this by preparing the equation:
Mass = concentration (mol/L) x volume (L) x Molar mass
Mass = 1.0 M x 2.5 L x 40 g/mol
Mass = 100 g
Answer:
[tex]100\; \rm g[/tex] of [tex]{\rm NaOH}\; (s)[/tex] would be required.
Explanation:
The quantity of solute in a solution of concentration [tex]c[/tex] and volume [tex]V[/tex] would be [tex]n = c \cdot V[/tex].
It is given that volume [tex]V = 2.5\; \rm L[/tex] for the solution in this question. It is also given that the concentration of the [tex]\rm NaOH[/tex] solute in this solution is [tex]c = 1.0\; \rm M[/tex], which is the equivalent to [tex]c = 1.0\; \rm mol \cdot L^{-1}[/tex].
Apply the equation [tex]n = c \cdot V[/tex] to find the quantity of [tex]\rm NaOH[/tex] in this solution:
[tex]\begin{aligned}n &= c \cdot V \\ &= 1.0\; \rm mol \cdot L^{-1} \times 2.5\; \rm L \\ &= 2.5\; \rm mol\end{aligned}[/tex].
Multiply the quantity [tex]n[/tex] of [tex]\rm NaOH[/tex] in this solution with the formula mass [tex]M[/tex] of [tex]{\rm NaOH}\![/tex] to find the corresponding mass:
[tex]\begin{aligned}m &= n \cdot M \\ &= 2.5\; \rm mol \times 40\; \rm g \cdot mol^{-1} \\ &= 100\; \rm g\end{aligned}[/tex].
Thus, this solution would contain [tex]100\; \rm g[/tex] of [tex]{\rm NaOH}[/tex].
It would thus take [tex]100\; \rm g[/tex] of [tex]{\rm NaOH}[/tex] to prepare this solution.

Which of the following has resulted?
A.
a balanced force moving everyone in Daniel and Maria's direction
B.
a balanced force leaving everyone in the same place
C.
an unbalanced force moving everyone in Daniel and Maria's direction
D.
an unbalanced force moving everyone in Bryan and Alyssa's direction
The correct answer is Option (C) An unbalanced force moving everyone in Daniel and Maria's direction.
What is balanced force?The force which is opposite in direction and equal in size.A man pushing a wall is example of balanced force.What is unbalanced force?The force which changes the speed , position and direction of the object to which it is applied is known as unbalanced force ,Turning a cartwheel is an example of unbalanced force.
Why Other options are incorrect? Bryan and Alyssa are exerting a combined force of 10 N.Daniel and Maria are exerting 12 N of forceAs , a result the force applied by the Daniel and Maria is greater then the force applied by Bryan and Alyssa So the direction of Bryan and Alyssa changes.Hence , an unbalanced force moving everyone in Daniel and Maria's direction

A container has 1.50 moles of hydrofluoric acid molecules, a deadly acid that
can kill someone in minutes. How many molecules is this?
A container has 1.50 moles of hydrofluoric acid molecules, a deadly acid that can kill someone in minutes molecules are 9.03 × 10 ²³ molecules.
What are moles?Moles are the smallest unit of a molecule that participates in the formation of the molecules to compete in a reaction and the value will be equal to the Avogadro number 2.303 × 10 ²³.
To calculate the total number of molecules the value of one mole is 2.303 × 10 ²³. so, for 1.50 moles of hydrofluoric acid will be,
1.50 moles = 2.303 × 10 ²³.moles
hydrofluoric acid molecules = 1.50 × 2.303 × 10 ²³
hydrofluoric acid molecules = 9.03 × 10 ²³ molecules.

21. When considering the Bohr model of a neon atom, which of the following is a true statement?
Ten protons would be located in the nucleus, and 10 neutrons would be on the outside of the atom orbiting in rings.
Ten protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.
O Ten protons would be located in the nucleus, and 20 neutrons would be on the outside of the atom orbiting in rings.
OTwenty protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.
The characteristics of the Bohr model allow you to find that the correct answer for the distribution of particles in the atom is:
b) Ten protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.
The bohr model was initially developed for hydrogen, where it manages to fully explain the spectrum of the hydrogen atom, it was quickly spread to other multi-electronic atoms with the characteristic of having a single electron in their last orbit.
The extension to atoms with more than one electron in the last shell the model results are not completely correct.
The Bohr model uses Rutherford's knowledge that the atomic nucleus is a very small part of an atom that contains all its mass, that is, it contains the protons and neutrons and the electrons are in circular orbits around the nucleus.
In the case presented of Neon, its electronic configuration is
1s² 2s² 2p⁶
Let's examine the different claims:
a) False. Protons and neutrons form the mass of the atom, therefore they are both in the nucleus.
b) True. The protons are in the nucleus and the electrons are in circular orbits.
c) False. All protons and neutrons must be in the nucleus, plus neon only has 10 neutrons.
c) False. The number of protons determines the type of atom. An atom with twenty protons is Calcium atom .
In conclusion, using the characteristics of the Bohr model we can find that the correct answer for the distribution of particles in the atom is:
b) Ten protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.

measles
strep throat
Measles is a communicable disease that requires immunization to prevent illness when exposed to it.
Measles is a communicable disease and highly contagious. It is usually very serious in children. The disease can be contacted through droplets in the air, physical contact and through mother-to-child transmission.
It is a very serious disease as it is caused by a virus which replicates very fast in the throat and nose thereby creating symptoms such as runny nose, coughing, sneezing and is usually accompanied with a rash.
The severity and death rates is what gave rise to the creating of a measles vaccine which is usually given to babies after birth to make them immune to the potential exposure to the virus.
Diabetes, bronchitis and strep throat have no vaccine as they can always be treated or managed with over-the-counter drugs.

why is it that lipids, such as oil, do not readily mix with water?
Answer:
Liquid water is held together by hydrogen bonds. Oils and fats not have any polar part and so for them to dissolve in water they would have to break some of water s hydrogen bonds.Water will not do this so the oil is forced to stay separate from the water.
Oil are the lipid molecule do not Mix With Water Because of Polarity. Oil and water don’t mix as it is made up of non-polar molecules while water molecules are polar.
what are the composition of lipid ?Lipids are organic biomolecule made up of carbon, hydrogen and oxygen with some other elements like phosphorus and nitrogen may be present.
A fatty acid which is an organic acid having hydrogen and general formula R-COOH where R represents hydrogen or a group of carbon and hydrogen atoms, for example stearic, palmitic and oleic acids.
