Answer:

carbon atoms

Explanation:

Let us look at the molecular formulas of each compound;

Butanol= C4H10O

Butene= C4H8

We can clearly see that the both compounds contains four carbon atoms each. Hence the correct answer is that the both compounds contain the same number of carbon atoms

Answer:

Quantum Mechanical Model of Atom

The solution of the wave equation brings the idea of shells, sub-shells and orbitals. The probability of finding an electron at a point within an atom is proportional to the |ψ|2 at that point, where ψ represents the wave-function of that electron.

Answer:

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L}\\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{5.00 \times {10}^{26} }{6.02 \times {10}^{23} } \\ = 830.5647..[/tex]

We have the final answer as

Cadmium (Cd), Mercury (Hg), and Copernicium (Cn).

Answer:

79.9 amu

Explanation:

Given data:

Atomic mass of bromine = ?

Percent abundance of 1st isotope = 50.7%

Atomic mass of 1st isotope = 78.92 amu

Percent abundance of 2nd isotope = 49.3%

Atomic mass of 2nd isotope =80.92 amu

Solution:

Average atomic mass  = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)  / 100

Average atomic mass = (50.7×78.92)+(49.3×80.92) /100

Average atomic mass =  4001.24 + 3989.36 / 100

Average atomic mass = 7990.6 / 100

Average atomic mass = 79.9 amu.

Answer:

0.74 moles of oxygen are required for combustion

Explanation:

Given data:

Number of moles of oxygen required = ?

Mass of Mg = 35.5 g

Solution:

Chemical equation:

2Mg + O₂         →       2MgO

Number of moles of Mg:

Number of moles = mass/molar mass

Number of moles = 35.5 g/ 24 g/mol

Number of moles = 1.48 mol

Now we will compare the moles of Mg with oxygen.

                  Mg           :         O₂

                   2             :          1

                 1.48           :        1/2×1.48 = 0.74 mol

0.74 moles of oxygen are required for combustion.

Answer:

deposition

Explanation:

The model above shows a transition from a gas state to a solid state. This is known as "deposition."

The particles are widely-spaced on the left because they have a lot of energy; thus, they don't interact with each other. This is the reason why the gas doesn't have a definite shape and volume.

The particles on the right are stacked near the bottom because they don't have enough energy to move about; thus they interact with each other. This gives solid a definite shape and a definite volume. They can only move if the thermal energy increases.

Answer: .03 M

Explanation:

you have to use m1v1 = m2v2

    but the units should be in L so we need to convert the 32.20 and 26.60 into L by dividing them by 1000. So now we have .0322 and .2660

         .0322(.25)=(.2660)(x)

Answer: 1 . Unsaturated Solution

2. Saturated  Solution

Explanation:

1 ..tedsaturauntionsolu----------- Unsaturated Solution

2. ratedsatulutisoon--------------Saturated  Solution

 An Unsaturated solution is defined as  a  solution which contains  an amount of solute  that dissolves completely since the amount of solute  is still  less than the maximum amount that can readily dissolve in such solution and an additional amount of solute if added continues to dissove in the solution. Here the solution is still less than the equilibrium point.

example include. Addition of salt or sugar in water and it dissoves completely.

A saturated  solution is defined as A solution  which contains a maximum amount of solute that an additional solute will no longer be capable of being dissolved further since its equilibrium point has been reached.

Example- The addition of sugar to water till it no longer dissolves

Carbonated water is a saturated solution saturated with carbon as can be seen in the air bubbles  it gives offf in form of carbon.
