Answer: 2. I see two colours in the test tube, white and grey at the bottom.
The formula you need is: heat= specific heat x mass x ΔT
specific heat= 0.46 j/g-C
mass= 100.0 grams
ΔT= 40.2 - 15.0= 25.2C
heat= (0.46) x (100.0) x (25.2)= 1159.2 joules or 1200 joules (rounded off)
Explanation:
Single covalent bonds
When an atom needs 1 electron to attain noble gas configuration they share rhe atoms in order to gain this ex ; H2 molecule
double covalent; O2 molecule
triple covalent; N2 molecule
