a = acceleration of the object
Those two multiplied are equivalent to force.
Answer:
i dont get it
Explanation:
can u explain it more man?
When liquid state is being converted to solid state, atoms come closer to each other and their speed of movement also decreases. Instead of moving about in the substance, they are only able to vibrate about their positions in solid. Hence, this change leads to loss of energy. Similarly, atoms loose energy when state changes from gas to liquid.
Answer:- 30 moles of oxygen are required if 12 moles of 
are consumed.
Solution:- The given balanced equation is:
From this balanced equation, there is 2:5 mol ratio between and 
.
We are asked to calculate the moles of required to react with 12 moles of .
It's a mol to mol conversion and the set up for this would be as:
= 
So, 30 moles of oxygen are required to react with 12 moles of .
