Answer:
1,2,3
Explanation:
Heat gain implies that heat is absorbed by the system in order to make the stated phase transition possible.
Before a liquid changes to gas, intermolecular forces in the liquid are broken by energy supplied as heat.
Also, transition from solid to liquid requires energy to break intermolecular bonds.
Finally, sublimation requires input of energy in the form of heat.
Answer:
d
Explanation:
e works, a and b one of them is stronger but it works d is the only logical answer
PV
= nRT
We
are solving for pressure. We are given the volume, which is 0.100 L (equivalent
to 100 mL). The temperature is 273.15 K (equivalent to 0 Celsius). All we need
to do is convert the grams to moles before we can solve for pressure.
N₂
has a molecular mass of 28.02. This means that 510 g N₂ * (1 mole N₂/28.02 g
N₂) = 18.2 moles N₂
PV
= nRT
P
= nRT/V
R
is the gas constant. R = 0.08206 atm*L/(K*mol)
P
= (18.2 mol)*(0.08206 atm*L/(K*mol))*(273.15 K) / (0.100 L)
<span>P
= 4.08 *10^3 atm</span>

</span>
<span>The pressure is 4.08*10^3 atm.</span>
Answer:
The answer to your question is below
Explanation:
Organic chemistry studies the compounds that have carbon, hydrogen, oxygen and other elements in their structure.
Carbohydrates are biomolecules that are composed of carbon, hydrogen, and oxygen that is why they are studied by organic chemistry.
Other biomolecules that are also studied by organic chemistry are Proteins, Lipids, and Vitamins.
