Answer:
it's harmful
Explanation:
it's harmful to our environment it can endanger our planet and endangered animal species it can also kill lots of plants and we have a hard time burning fossil fuels with limited factories which costs a lot of money.
Answer: The valency of oxygen is 2, because it needs two atoms of hydrogen to form water.
Explanation: The nearest noble gas to magnesium is neon with electronic configuration of [2,8], to achieve this stable electronic configuration Mg can lose 2 valence electrons, hence its valency is 2 + ^+ +
When you burn a log in your fireplace you are converting c<span>ellulose into carbon dioxide and water.

Wood is made from cellulose. When wood burns, cellulose reacts with oxygen from the air and it forms carbon dioxide and water vapor.
The reaction of the combustion of glucose is as follows:
C₆H₁₂O₆ + 6O₂ = 6 CO₂ + 6H₂O
When wood burns, we notice that it slowly disappears because it passes into the mentioned gases. The ash that is created is part of the wood that did not burn.
Answer:
Explanation:
To calculate the reduced mass of nitrogen molecule = Mn x Mn/ Mn + Mn
Mn = atomic mass of Nitrogen = 14.00
reduced mass = 14 x 14 /14 + 14 = 7
Similarly for HCl; reduced mass for a hydrogen chloride molecule = Mh x Mcl/Mh + Mcl
where Mh = atomic mass of hydrogen = 1.008
Mcl = atomic mass of chrorine = 34.97
reduced mass for HCl = 1.008 x 34.97 /1.008 + 34.97
= 0.97
