Answer: The correct option is C.

Explanation:

Speed is defined as the distance traveled per unit time. It is a scalar quantity as it can be described by the magnitude alone.

Velocity is defined as the distance per unit time in a given direction. It is a vector quantity as both magnitude and direction are required to describe it.

For two people to have same speed and velocity, they both should have same magnitude and should move in the same direction.

By this, the correct option will be C.

When 28 g of nitrogen and 6 g of hydrogen react, 34 g of ammonia are produced. If 100 g of nitrogen react with 6 g of hydrogen,
love history [14]

Answer:

34 g

Explanation:

Let's consider the following balanced equation.

N₂ + 3 H₂ → 2 NH₃

The theoretical mass ratio of N₂ to H₂ is 28g N₂ : 6g H₂ = 4.6g N₂ : 1g H₂.

The experimental mass ratio of N₂ to H₂ is 100g N₂ : 6g H₂ = 16.6g N₂ : 1g H₂.

As we can see, hydrogen is the limiting reactant.

According to the task, we 6 g of H₂ react completely, 34 g of ammonia are produced.

Calculate the percent composition of chlorine in methyl trichloride, CHCl3.
vovikov84 [41]

Answer:

Chlorine --> 89%

Explanation:

Step 1) Add each element's amu up to get the total mass of the compound.

12.011+1.008+3(35.453) = 119.378.

Step 2) Divide the total mass of chlorine by the total mass of the compound.

3(35.453) = 106.359

106.359/119.378 = 0.8909430548.

Step 3) Now multiply by 100 to get the percentage.

0.8909430548*100 = 89.09430548%

Step 4) Estimate and submit your answer

89.09430548% estimates to 89%
