Answer:

2HgO    →     2Hg      +  O₂

The reaction is a decomposition reaction because from one reactant two products were obtained

Explanation:

The problem here involves balancing the chemical reaction given and also classifying the reaction.

 The unbalanced expression is given as:

              HgO    →     Hg      +  O₂

Assign the alphabets a,b and c as coefficients that will balance the equation

           aHgO    →     bHg      +  cO₂

Conserving Hg: a  = b

                   O:    a  = 2c

So, let c  = 1, a  = 2 b  = 2

Therefore;

       2HgO    →     2Hg      +  O₂

The reaction is a decomposition reaction because from one reactant two products were obtained

Calcium hydroxide is more soluble in water than the magnesium hydroxide .why?​
N76 [4]

Explanation:

This indicates that there are more hydroxide ions in solution than there were in the original water. This is because some magnesium hydroxide has dissolved. Calcium hydroxide solution is referred to as "lime water". A liter of pure water will dissolve about 1 gram of calcium hydroxide at room temperature.

in sexual reproduction, of each chromosome in a pair has the same genes, how is genetic variety possible?
Sliva [168]

This answer will depend on if you are speaking about asexual reproduction or not.

Variety is possible here because the the product genes are half from the mother and half from the father. So a child might have blue eyes from his mother, but red hair from his father, etc. Different genetic mutations are the initial cause of all differentiation between genes, which are passed down from each generation to the next through this same process.

In Asexual reproduction, all reproductions are essentially clones of the parent, and no genetic variation, other than mutations will occur.

All organic molecules have what element in common? a carbon b nitrogen c phosphorus d sulfur
Murrr4er [49]

Answer:

a) Carbon.

Explanation:

The organic chemistry is normally based on the chemical elements Carbon, Hydrogen,oxygen, sulphur and Nitrogen. Sometimes a mixture or compound of one or more of these will be found such as  (carbohydrates, fats, proteins). The varieties of organic molecules are based on these atoms, with carbon as the skeleton of the organic molecule.

Hence out of the four options given we find that though nitrogen, sulphur are also common in organic the most common is the first option

a) Carbon.

What is the concentration of nitrate ion in a 425 mL solution containing 32.0 g of Mg(NO3)2 (M = 148.3)?
Brums [2.3K]
<span>There are a number of ways to express concentration of a solution. This includes molarity. Molarity is expressed as the number of moles of solute per volume of the solution. Calculations are as follows:

Molarity of NO3 ion = 32.0 g Mg(NO3)2 ( 1 mol / 148.3 g ) ( 2 mol NO3 / 1 mol Mg(NO3)2) / .425 L
MOlarity of NO3 ion = 1.02 M </span><span>
