Answer:

The answer to your question is the letter D. 12

Explanation:

Unbalanced chemical reaction

               Al(OH)₃  +  H₂SO₄  ⇒   Al₂(SO₄)₃  +  H₂O

           Reactants              Elements         Products

                  1                            Al                      2

                  1                            S                       3

                  5                            H                      2

                  7                            O                      13

Balanced chemical reaction

              2Al(OH)₃  +  3H₂SO₄  ⇒   Al₂(SO₄)₃  +  6H₂O

           Reactants              Elements         Products

                  2                            Al                      2

                  3                            S                       3

                 12                            H                     12

                 18                            O                     18

Sum up the coefficients

Result = 2 + 3 + 1 + 6

          = 12

How do valence electrons interact between non polar covalent, polar covalent, and ionic bonds?​
iVinArrow [24]

Answer:

In non-polar covalent bonds, the electrons are equally shared between the two atoms. For atoms with differing electronegativity, the bond will be a polar covalent interaction, where the electrons will not be shared equally.

What volume would a sample of gas occupy in LITERS at 0.985 atmospheres and a volume of 3.65 liters if the pressure were raised
musickatia [10]

Answer:

3.18 L

Explanation:

Step 1: Given data

  • Initial pressure (P₁): 0.985 atm
  • Initial volume (V₁): 3.65 L
  • Final pressure (P₂): 861.0 mmHg
  • Final volume (V₂): ?

Step 2: Convert P₁ to mmHg

We will use the conversion factor 1 atm = 760 mmHg.

0.985 atm × 760 mmHg/1 atm = 749 mmHg

Step 3: Calculate the final volume of the gas

Assuming ideal behavior and constant temperature, we can calculate the final volume using Boyle's law.

P₁ × V₁ = P₂ × V₂

V₂ = P₁ × V₁/P₂

V₂ = 749 mmHg × 3.65 L/861.0 mmHg = 3.18 L

How do you balance a chemical equation
Dominik [7]
There should be mass balance and the charge balance between the reactants and the products

Mass balance : total no of individual atoms of each type should be balanced before and after the reaction

Charge balance : Overall charge of the reactants should be balanced with the overall charge of the products

You can balance,

1)by just looking at it

2)by Algebraic method given above or

3)by the redox method

You need to know how to get the oxidation numbers in order to use the oxidation method
