Answer:
Both
Explanation:
The combined gas law is also known as the general gas law.
From the ideal gas law we assume that n = 1;
So;
PV = nRT
and then;
= 
If we cross multiply;
P₁V₁T₂ = P₂V₂T₁
So;
T₁ = 
Also;
V₂ = 
So from the choices both are correct
Answer:
30.06904
Explanation:
C3H4: Mass % C = 36.033 x 100 / 40.0641 = 89
The bowling ball have more gravitational potential energy as it sit on top of the building
<u>Explanation:</u>
The energy that is possessed by an object due to the position of that object in the field of gravity is called Gravitational potential energy . The object that is present in the place that is very closer to the Earth's surface has a constant gravitational potential energy. When an object is at certain height there is a necessity of force for lifting that object form that height.
This is applies to the gravitational potential energy also.When two objects are placed at different heights, the object that is placed at the greater height will have more potential energy. This is because, the force necessary to take the object from greater height will be more.
Answer:
D. The coefficients give the ratio of mole reactant to moles product.
Explanation:
In stoichiometric calculations, the amount of product formed from reactants can be determined.
- Using this approach, the number of moles of reactants and products on both sides of the expression must be balanced.
- As a rule of thumb, the coefficients give the ratio of moles of reactants to moles of products.
- This is very useful in a number of calculations using the stoichiometric approach.
