How many moles of hydrogen are required to react with 4.6 x 10 22 molecules of nitrogen?
V125BC [204]

Answer: 6 moles

Take a look at the balanced chemical equation for this synthesis reaction

N 2(g] + 3 H 2(g] → 2 NH 3(g]

Notice that you have a  1:3  mole ratio between nitrogen gas and hydrogen gas. This means that, regardless of how many moles of nitrogen gas you have, the reaction will always consume twice as many moles of hydrogen gas.

So, if you have  2 moles of nitrogen taking part in the reaction, you will need

2 moles N 2 ⋅ 3 moles H 2 /1 mole N 2 = 6 moles H 2

A car is traveling at 15kph and speeds up to 30kph in 5 seconds. What is its acceleration?
Wewaii [24]

Answer:

the acceleration is 3 k/h/s

Explanation:

The formula for acceleration is Δv/t, so change in velocity divided by time.

The original velocity is 15 kph, and the final velocity is 30 kph. Therefore, the change in velocity is 15 kph. 15/5=3 k/h/s
