How mu heat energy, in joules, is absorbed when 150 grams of water is warmed from 38.8°c to 96.3°c?
Likurg_2 [28]
Use this equation:

q = mc∆T

q is the heat energy your trying to find out

m is the mass of water (150g)

c is the specific heat capacity of water (4.18)

∆T is the temperature change (96.3-38.8)

so just multiply m c and ∆T to find q in joules

The formation of ammonia gas involves reacting hydrogen gas and nitrogen gas in a mole ratio of 3 to 1. as shown below:

  • N_2 + 3H_2 \rightarrow 2NH_3
<h3>What is the equation of the formation of ammonia?</h3>

Ammonia gas is formed from the reaction between nitrogen gas and hydrogen gas.

Three moles of hydrogen gas will react with 1 mole of nitrogen gas to form 2 moles of ammonia gas.

The equation of the reaction is given below as:

N_2 + 3H_2 \rightarrow 2NH_3

Therefore, the formation of ammonia gas involves reacting hydrogen gas and nitrogen gas in a mole ratio of 3 to 1.

PLEASE ANSWERRRRR: A by-product of both fission and fusion is: Question 1 options: Beta particle Alpha Particle Energy Proton
9966 [12]

A by-product of both fission and fusion is Energy.  

Fission and fusion are nuclear reactions in which a large amount of energy is produced. Fission is actually the splitting of nuclei that is heavy and unstable into lighter nuclei in which large amount of energy is released and fusion is combination of two lighter nuclei that releases large amount of energy.

So fission and fusion both released large amount of energy.
