Answer:
The mathematical equation, N = n × NA, can be used to find the number of atoms, ions or molecules in any amount (in moles) of atoms, ions or molecules: 10 moles of helium atoms = 10 × (6.022 × 1023) = 6.022 × 1024 helium atoms.

Answer:
C: The surroundings heat up and the system decreases in volume.
D: The surroundings heat up and the system does not change volume.
B: The surroundings heat up and the system expands in volume.
A: The surroundings get cold and the system decreases in volume.
Explanation:
The most exothermic reactions are those that release heat, that is to say, they give up the heat as it cools and the surroundings heat up.
As for endothermics, that is, those that absorb or capture the heat of the medium, they are variables that cool the environment that surrounds them and increase their internal temperature
Given that the volume of cylinder at STP = 11.2 L
Standard temperature = 273 K
Standard pressure = 1 atm
Calculating the volume of gas at 202.6 kPa and 300. K:
Applying the combined gas law,
= 
Plugging in the values and calculating final volume:
Therefore the correct answer will be, b) 6.15 L
