Answer:
Molecular formula of cyanogen is C₂N₂
Explanation:
We apply the ideal gases law to find out the mole of cyanogen
P . V = n. R. T
Firstly let's convert the pressure in atm, for R
750 mmHg = 0.986 atm
25°C + 273 = 298K
0.986 atm . 0.714L = n . 0.082 L.atm/mol.K .298K
(0.986 atm . 0.714L) / (0.082 L.atm/mol.K .298K) = n
0.0288 mol = n
Molar mass of cyanogen = mass / mol
1.50 g /0.0288 mol = 52.02 g/m
Let's apply the percent, to know the quantity of atoms
100 g of compound contain 46.2 g of C and 53.8 g of N
52.02 g of compound contain:
(52.02 . 46.2) / 100 = 24 g → 2 atoms of C
(52.02 . 53.8) / 100 = .28 g → 2 atoms of N
Noice but I don’t get why was this necessary
Answer:
Gravity
Explanation:
Gravity is what causes you to weigh more or less.
What is gravity? Gravity is the force that pulls things together. Larger things with larger masses have more gravity. When you are on Earth, you would weigh more than on the moon, about 6 times more, in fact, because the gravity on Earth is 6 times stronger.
Answer:
heat
Explanation:
because it's the cause of change
