Answer: it will gain them by multiplying the electrons
Explanation:
its like 2 + 2=4
4+4=8
Lithium is in the first column of the periodic table and thus can only form one bond with another atom (its ion is Li+)
Oxygen can form two bonds (as in the dioxygen O2).
Hence if you conbine Li and O it has to be Li2O.
Haber process is the large scale manufacture of a ammonia by reacting nitrogen and hydrogen at a ratio of 1:3
Change in hydrogen concentration is 0.45 - 0.16 = 0.29 moles/l
Therefore, the average rate of reaction of hydrogen = 0.29 / 30 = 0.0096
= 0.0096 moles/liter/sec
35.51 times 0.2 is 7.102
So you should tip $7.102
Answer:
ΔU° = 56.0 J
Explanation:
Step 1: Given data
- Work done to compress the gas (w): 83.0 J (When work is done on the gas, w is positive).
- Heat given off to the surroundings (q): -27.0 J (When heat is released to the surroundings, q is negative)
Step 2: Calculate the change in the internal energy of the gas (ΔU°)
The internal energy of a gas is the energy contained within it. We can calculate it using the following expression.
ΔU° = q + w
ΔU° = -27.0 J + 83.0 J
ΔU° = 56.0 J
