Answer:- g of carbon dioxide.
Solution:- The balanced equation for the combustion of methane is:
There is 1:1 mol ratio between methane and carbon dioxide. Grams of methane are converted to moles and then using mol ratio we get the moles of carbon dioxide that could further be converted to grams. The calculations are shown as:
=
So, complete combustion of given amount of methane gives .
Answer:
D. It will continue moving in a straight line.
Explanation:
When Fredo takes a ball and tosses it into space, the ball will move upward infinitely.
Gravity is the downward force that acts on an object.
Without gravity, or without the effect of gravity, an object will continue to move in its path with the original direction applied to it.
The mass of carbon contained in 2.25 g of potassium carbonate, K₂CO₃ is 0.196 g.
<h3>
Molecular mass of potassium carbonate</h3>
The molecular mass of potassium carbonate, K₂CO₃ is calculated as follows;
M = K₂CO₃
M = (39 x 2) + (12) + (16 x 3)
M = 138 g
mass of carbon in potassium carbonate, K₂CO₃ is = 12 g
The mass of carbon contained in 2.25 g of potassium carbonate, K₂CO₃ is calculated as follows;
138 g ------------ 12 g of carbon
2.25 g ------------ ?
= (2.25 x 12) / 138
= 0.196 g
Thus, the mass of carbon contained in 2.25 g of potassium carbonate, K₂CO₃ is 0.196 g.
