Answer:
19.8 kg of C₂H₂ is needed
Explanation:
We solve this by a rule of three:
If 1251 kJ of heat are relased in the combustion of 1 mol of acetylene
95.5×10⁴ kJ of heat may be released by the combustion of
(95.5×10⁴ kJ . 1) /1251kJ = 763.4 moles of C₂H₂
Let's convert the moles to mass → 763.4 mol . 26 g/1 mol = 19848 g
If we convert the mass from g to kg → 19848 g . 1kg / 1000g = 19.8 kg
Answer:
Estuaries are often called the “nurseries of the sea”
Explanation:
Because so many marine animals reproduce and spend the early part of their lives there.
B. curiosity and i know because i had the exact question
Condensation happens<span> when the temperature of air containing moisture decreases. falling air temperatures cause condensation because warm air can hold more moisture than </span>cold<span> air. when warm air in the </span>bathroom<span> is heated by the shower to temperatures as much as 100 degrees F, the air becomes saturated with moisture, hope it helps</span>
