How does the flow of energy during freezing compare with the flow of energy during melting
lianna [129]

Answer:

At the melting point, some molecules overcome the forces of attraction. Energy gained after the the solid melts increases the average kinetic energy or the temperature. When liquid is freezing the energy flows out the the liquid. As the kinetic energy decreases, they move more slowly.

A beaker cannot be used for measuring the volume of a liquid because _____.
Ad libitum [116K]

Answer:

Data obtained can't be accurate.

Explanation:

A beaker can't be used for measuring the volume of a liquid because they did not calculate volume of a liquid accurately and precisely. The marks present on the beaker are not accurate, it is just an estimate so by measuring the volume of any liquid using beaker give us a false data so that's why beaker are not used for the measurement of a volume.

You can purchase nitric acid in a concentrated form that is 70.3% HNO3 by mass and has a density of 1.41 g/mL. Describe exactly
Andrej [43]
The way to working out the numbers is to increase the measure of HNO3 required by the molarity to discover what number of moles you require: 0.115. You ought to have the capacity to make sense of the recipe weight H is 1, N is 14, O is 16. The result of the quantity of moles duplicated by the recipe weight ought to give an esteem in grams. You can utilize the thickness to change over to a volume of HNO3 to add to the right volume of water.

Molarity of a salt water solution of "0.47" moles of NaCl dissolved in a volume of 0.25L
asambeis [7]

Answer:

1.88 M

Explanation:

The following data were obtained from the question:

Mole of NaCl = 0.47 mole

Volume of solution = 0.25L

Molarity =?

Molarity is defined as the mole of solute per unit litre of the solution. It can represented mathematically as:

Molarity = mole /Volume

Using the above formula, the molarity of the salt water solution can be obtained as follow:

Molarity = 0.47/0.25

Molarity = 1.88 M

When the equation Al(OH)₃ + H₂SO₄ ---> Al₂(SO₄)₃ + H₂O is balanced, the sum of the balancing coefficients is
denis-greek [22]

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
