THE ANSWER
for solving this, we just use the formula of the equation of state
PV = n RT
where
P: pressure =10atm
V volume
n number of mole = 35.8 moles
R universal gas constant = 0.082
T: The temperature= 70°C= 343.15 Kelvin
therefore, for finding V
we have
V= (n RT) / P = 35.8 x 0.082 x 343.15 / 10 = 100.7 ≈ 101 L
the answer is V = 101L
The more focused the rays are, the more energy an area receives, and the warmer it is. The lowest latitudes get the most energy from the Sun. The highest latitudes get the least. The difference in solar energy received at different latitudes drives atmospheric circulation.
Answer:
78.12g of acetylene
Explanation:
Acetylene and calcium hydroxide are produced when H₂O reacts with CaC₂. The reaction is:
2 H₂O + CaC₂ → C₂H₂ + Ca(OH)₂
<em>Where 1 mole of C₂H₂ (acetylene) is produced per mole of CaC₂</em>
Thus, the addition of 3 moles of CaC₂ produces 3 moles of acetylene.
As molecular mass of acetylene is 26.04g/mol, grams of acetylene produced are:
3mol C₂H₂ × (26.04g / mol) = <em>78.12g of acetylene</em>
