Vinegar is the only thing listed
The molecular weight of Mg(OH)2 : 58 g/mol
<h3>Further explanation</h3>
Given
Mg(OH)2 compound
Required
The molecular weight
Solution
Relative atomic mass (Ar) of element : the average atomic mass of its isotopes
Relative molecular weight (M) : The sum of the relative atomic mass of Ar
M AxBy = (x.Ar A + y. Ar B)
So for Mg(OH)2 :
= Ar Mg + 2 x Ar O + 2 x Ar H
= 24 g/mol + 2 x 16 g/mol + 2 x 1 g/mol
= 24 + 32 + 2
= 58 g/mol
The answer is A it's a basic because once you add another substance to a neutral it either becomes acidic or basic. this one becomes basic because the hydroxide ion concentrate increased.
Answer:
Yes, wind and temperature are responsible for the spreading of fire.
Explanation:
Chemistry play a key role in the chemical reaction that is occurring in the wildfires because chemistry is the study of chemicals and in wildfires, the reaction of chemicals is responsible for the occurring and spreading of fire. Yes, wind currents and temperature has a great influence on the fire spreading in the forests. The fire occurs in the forest is due to temperature while its spreading happens due to wind. Placing water on the fire does not help extinguish the fire because the the fire particles can be transmitted for a fair distance by wind.
Explanation: C) the air temp. at the top is lower
