Answer:
52.36 grams of water was produced when 32 grams of propane was burned in excess of oxygen gas.
Explanation:
Moles of propane =
According to reaction, 1 mole of propane gives 4 moles of water.
Then 0.7273 moles of propane will give:
of water
Mass of 2.909 moles of water:
= 2.909 mol × 18 g/mol = 52.36 g
52.36 grams of water was produced when 32 grams of propane was burned in excess of oxygen gas.
The grand canyon is 884 m deep
<h3>Formula for velocity of echo</h3>
The velocity of an echo can be obtained by using the following formula
v = 2x / t
Where
- v is the velocity
- x is the distance
- t is the time
With the above formula, we can determine how depth the grand canyon. Details below:
<h3>How to determine the depth of the grand canyaon</h3>
- Velocity (v) = 340 m/s
- Time (t) = 5.2 s
- Depth (x) =?
v = 2x / t
340 = 2x / 5.2
Cross multiply
2x = 340 × 5.2
2x = 1768
Divide both sides by 2
x = 1768 / 2
x = 884 m
Thus, the grand canyon is 884 m deep
