If the balloon is closed, then yes, both volume and pressure will increase when the gas inside is heated.
What is pressure?
Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
Various units are used to express pressure. Some of these are units of force divided by units of area. For example, the SI unit of pressure, Pascal (Pa), is 1 Newton per square meter (N/m2). Similarly, pounds force per square inch (psi, symbol lbf/in2) is the traditional unit of pressure in imperial and US systems. Pressure can also be expressed as standard atmospheric pressure. Atmospheric pressure (atm) is equal to this pressure and torr is defined as 1/760 of this. Manometric units such as centimeters of water, millimeters of mercury, and inches of mercury are used to express pressure as the height of a particular liquid column within a manometer.
If the balloon is closed, then yes, both volume and pressure will increase when the gas inside is heated.

Indicate whether each statement is true or false. Drag the appropriate statements to their respective bins. the octet rule is based on the fact that filling in all s and p valence electrons in a shell gives eight electrons. compounds in which nitrogen is the central atom are frequent exceptions to the octet rule because they have too many electrons surrounding the nitrogen. boron compounds are frequent exceptions to the octet rule because they have too few electrons surrounding the boron. the si in sih4 does not follow the octet rule because hydrogen is in an unusual oxidation state.
Answer:
the octet rule is based on the fact that filling in all s and p valence electrons in a shell gives eight electrons--- True
boron compounds are frequent exceptions to the octet rule because they have too few electrons surrounding the boron......True
compounds in which nitrogen is the central atom are frequent exceptions to the octet rule because they have too many electrons surrounding the nitrogen...... false
the si in sih4 does not follow the octet rule because hydrogen is in an unusual oxidation state......false
Explanation:
The octet rule simply means that atoms tend to be stable when they have eight electrons in their outermost shell. This rule mostly applies to the s and p orbitals and not to the d and f orbitals. The sum of the total electrons in the outermost s and p orbitals is often equal to eight for an atom to be considered stable, for example, the noble gases.
Boron often forms compounds which has less than eight electrons around the boron central atom because the compounds of boron often have a sextet of electrons owing to the fact that boron is trivalent and forms mostly covalent compounds.
Nitrogen compounds mostly obey the octet rule and do not have excess electrons. The oxidation state of hydrogen in SiH4 is not unusual.

Answer:
11.5 or 11.52, depending on however many decimal places you round it to
Explanation:
the equation for mass ( using the specific heat capacity equation) is energy transferred divided by temperature change x the specific heat capacity.
so, we do 725 ÷ 32° (the temp change) x 2.03 = 11.52 or 11.5, depending on how many decimal places you round to
i would round to 2 decimal places, so the answer would be 11.52kg.
mass is measured in kg :) hope this helped.
A sample of gas is kept at a temperature of 300 k, a volume of 1.45L, and a pressure of 3.00 kPa. How many moles of has are in the sample
Answer:
the number of moles of the gas is 0.00174 mol.
Explanation:
Given;
temperature of the, T = 300 K
volume of the gas, V = 1.45 L
Pressure of the gas, P = 3.0 kPa
The number of moles of the gas is calculated using Ideal gas equation, as follows;
PV = nRT
Where;
n is number of moles of the gas
R is the ideal gas constant, = 8.315 L.kPa/mol.K
n = PV / RT
n = (3 x 1.45) / (8.315 x 300)
n = 0.00174 mol.
Therefore, the number of moles of the gas is 0.00174 mol.

Explanation:
Describe what happens to the molecules in the ice as temperature of the ice increases
Answer:
When you heat ice, the individual molecules gain kinetic energy, but until the temperature reaches the melting point, they don't have energy to break the bonds that hold them in a crystal structure. They vibrate more quickly within their confines as you add heat, and the temperature of the ice goes up.
Answer:
As energy is transferred to the water molecules in the ice, the motion of the molecules increases. The motion of the molecules increases enough that it overcomes the attractions the water molecules have for each other causing the ice to melt.

How many moles do I have of Lithium if I have 116.3g
Answer:
16.85mol
Explanation:
The number of moles of a substance can be calculated by dividing the mass of that substance by its molecular mass. That is;
number of moles (n) = mass (m) /molar mass (MM)
Molar mass of lithium = 6.9g/mol
Hence,
number of moles = 116.3 ÷ 6.9
Moles = 16.85mol
Therefore, 16.85moles is present in 116.3g of Li.
Which of the following is deforestation most likely to cause?
A.
an increase in the amount of soil on Earth
В.
an increase in the amount of minerals on Earth
C.
an increase in the amount of carbon dioxide in Earth's atmosphere
D
an increase in the amount of ozone in Earth's atmosphere
Answer:
C
Explanation:
trees (as well as other plants) produce carbon dioxide. deforestation is the removal of trees. this will not cause an increase in any pollutants such as ozone. ozone is made from VOCs and other harmful pollutants, and not caused by trees. tearing down trees will also not create more soil. So the answer has to be C

Explanation:
A 1.26 g sample of He gas has a pressure of 0.123 arm and a volume of 32.6 L. What is the temperature of the sample, in degrees Celsius
A 1.26 g sample of He gas has a pressure of 0.123 arm and a volume of 32.6 L, then the temperature of the gas is -117.7 degree C.
How do we calculate the temperature of gas?Temperature of any gas will be calculated by using the ideal gas equation as:
PV = nRT, where
P = pressure of gas = 0.123 atm
V = volume of gas = 32.6 L
R = universal gas constant = 0.082 L.atm / K.mol
T = temperature of gas = ?
n is moles of He gas and will be calculated as:
n = W/M, where
W = given mass = 1.26g
M = molar mass = 4 g/mol
n = 1.26 / 4 = 0.315 moles
On putting values we get,
T = (0.123)(32.6) / (0.315)(0.082)
T = 155.41 K = 155.41 - 273.15 = -117.7 degree C
Hence required temperature of the helium sample is -117.7 degree C.

Answer:
True
Explanation:
The temperature of 200 mL of gas originally at STP is changed to –25o C at constant volume. Calculate the final pressure of the gas in mmHg.
Answer:
691.6 mmHg
Explanation:
At standard temperature and pressure, temperature of a system = 273K, and pressure= 1atm
T1= 273.15K
P1= 1atm
T2= (–25°C +273.15 )= 248.15K
From Gay-Lussac's law which expressed that at constant volume, pressure of a particular mass of gas is directly proportional to temperature . It can be expressed as
P1 / T1 = P2 / T2
Where P1= initial pressure
T2= final temperature
T1= initial temperature
P2= final pressure
Making P2 subject of the formula
P2= (P1 × T2)/ P1
Substitute the values we have
P2= (1 atm × 248.15K)/273.15
P2= 0.91 atm
But
1atm= 760 mmHg
0.91 atm= X mmHg
If we cross multiply we have
X mmHg= (760× 0.91)/1
= 691.6 mmHg
Hence, the final pressure of the gas in mmHg is 691.6 mmHg
