Question
How many moles of Na Cl will be produced from 6.0 moles of HCI?
Answer: 36.9 g
Explanation:
P4 + 5O2 = P4O10 Balanced equation
moles P4 present = 23.9 g x 1 mole/123.88 g = 0.193 moles
moles O2 present = 20.8 g x 1 mol/32 g = 0.65 moles O2
From balanced equation, mole ratio O2 : P4 is 5:1. Is 0.65 moles O2 5x 0.193 moles? NO. You don't have enough O2.
O2 is limiting in this reaction.
theoretical moles of P4O10 = 0.65 moles O2 x 1 mole P4O10/5 moles O2 = 0.13 moles P4O10
mass of P4O10 produced = 0.13 moles x 283.9 g = 36.9 g
Answer:
400 meters every 20 seconds
Explanation:
Answer:
=745 Kelvin
Explanation:
- According to the pressure law the relationship between the pressure and absolute temperature of a gas at a constant volume is directly proportional.
- An increase in temperature causes a corresponding increase in pressure at a constant volume.
That is;

Mathematically;

When there are two varying conditions;

In this case;
P1 = 0.8 atm
T1 = 25+273 = 298 K
P2 =2.00 atm
T2= ?
Therefore;



Therefore, the temperature can be raised up to 745 kelvin without bursting vessel.
The answer is B. Your welcome.
