Nitrogen gas consists of a diatomic nitrogen atom. So, the correct answer is B.
Answer is: <span>decomposition.
Balanced chemical reaction: H</span>₂CO₃ → CO₂ + H₂O.
H₂CO₃ is carbonic acid.
CO₂ is carbon (IV) oxide or carbon dioxide.<span>
Chemical decomposition is the separation of
a single chemical compound (in this example </span>carbonic acid<span>) into
its two or more simpler compounds (in this example water and
carbon dioxide).</span>
I believe the best answer to that question wud be D. I cud b wrong
Answer:
Q = 3937.56 J
Explanation:
Heat transferred due to change in temperature is given by :
c is the specific heat of water, c=4.18 J/g-°C
We have, m = 15 g, 
So,
Hence, 3937.56 J of heat is transferred.
Answer:
The atmosphere traps heat energy from the Sun and energy radiated from Earth's surface helping to maintain Earth's climate
Explanation:
Earth's atmosphere keeps much of the Sun's energy from escaping into space. This process, called the greenhouse effect, keeps the planet warm enough for life to exist. The atmosphere allows about half of the Sun's heat energy (50%) to reach Earth's surface.
