2H2 + O2 --&gt; 2 H2O<br> +<br> How many moles of oxygen is required to produce 13.3 moles of water?
LenKa [72]

Answer:

Explanation:

Let the number of moles of oxygen = x

2H2 + O2 --> 2 H2O

           x             13.3

Since the balance number for oxygen is 1 and the balance number for water is 2, you must set up a proportion. (Those balance numbers represent the number of moles).

1/x = 2 / 13.3                      Cross Multiply

2*x = 13.3                          Divide both sides by 2

2x/2 = 13.3/2

x = 6.65

You need 6.65 moles of oxygen.

What is the value of work done on an object when a 50–newton force moves it 15 meters in the same direction as the force?
victus00 [196]

Answer:

work done = 750 J

Explanation:

Given data:

Force on object = 50 N

Distance covered = 15 m

Work done = ?

Solution:

W = F. d

W = work done

F = force

d = distance

Now we will put the values in formula.

W = 50 N × 15 m

W = 750 N. m = 750 J

The correct answer is (b) political map

Instead of showing viewers what exists in the land, it shows those imaginary lines that serve to separate countries, states, territories, and cities. These maps generally include larger bodies of water, such as oceans, rivers, and lakes, as landmarks.

It was made by man not natural like the others maps.
