C. because it doesn't break down without chemicals, so it would eventually just pile up.
Answer:
44,901 kilo Joule heat is released when
grams of ammonia is produced.
Explanation:
Moles of ammonia gas produced :

According to reaction, when 2 moles of ammonia are produced 9.18 kilo joules of energy is also released.
So, When 978.235 moles of ammonia gas is produced the energy released will be:

(negative sign indicates that energy is released as heat)
44,901 kilo Joule heat is released when
grams of ammonia is produced.
It’s 5 atoms in this equation
Answer:
This is a synthesis reaction.
Explanation:
This is because nothing is being swapped out, reactants are being combined and then form a product.
Answer:
A) 0.831 M
B) 1.07 m
C) 26.2%
D) 0.0189
Explanation:
A) First we convert the mass of Pb(NO₃)₂ to moles:
- 275 g ÷ 331 g/mol = 0.831 mol Pb(NO₃)₂
Then we divide it by the total volume (1.00 L) to calculate the molarity:
- 0.831 mol / 1.00 L = 0.831 M
B) We convert the grams of water to kilograms:
Then we divide the Pb(NO₃)₂ by the kilograms of water:
- 0.831 mol / 0.775 kg = 1.07 m
C) We divide the mass of Pb(NO₃)₂ by the total mass of the solution:
*100%
* 100% = 26.2%
D) We calculate the moles of water:
- 775 g H₂O ÷ 18g/mol = 43.1 mol H₂O
Then we divide the Pb(NO₃)₂ moles by the total number of moles:
= 0.0189
