Answer:
These particles are all called atoms.
Explanation:
Atoms are referred to as the building blocks of all matter. This is because atoms are the smallest pieces that all matter can be broken down into, whether the matter is in a solid, liquid or gaseous state. Atoms combine to form bigger particles called molecules. These molecules are what forms the objects in our surrounding environment. Atoms are comprised of three particles: electrons which have a negative charge, protons which have a positive charge and neutrons which have no charge.
Answer: 139.57 L
Explanation:
Through Charles' Law, we know that volume and temperature have a proportional relationship meaning that if we increase the temperature, the volume will also increase. We can use the following formula: (V1/T1) = (V2/T2)
The equation of Charle's law requires temperature to be in ubnits of Kelvin.
So to find the new temp in kelvin, we use T + 273 so the two temps are 523 and 1123. Now we can plug in our values into the formula
(65/523) = (x/1123)
x= 139.57 L
782g
Explanation:
Given parameters:
Number of moles of N₂ = 23moles
Unknown:
Mass of NH₃ = ?
Solution:
We first obtain the balanced chemical equation for this reaction;
N₂ + 3H₂ → 2NH₃
From the equation we see that;
1 mole of N₂ produced 2 moles of ammonia
23 mole of N₂ will yield 2 x 23 = 46moles of ammonia
Now ;
mass of ammonia = number of moles x molar mass
Molar mass of NH₃ = 14 + 3(1) = 17g/mol
Mass of ammonia = 46 x 17 = 782g
