Answer:

A. It shows the same number of atoms of each element on both sides of the equation.

Explanation:

A balanced chemical equation demonstrates the conservation of matter by showing the number of atoms of each element on both sides of the equation or expression.

According to the law of conservation of matter, matter is neither created nor destroyed in the course of a chemical reaction but atoms are rearranged.

  • Based on this premise, the number of atoms or moles on both sides of the expression must be equal.
  • If there are 3 atoms of carbon on one side, the product must also reflect 3 atoms of carbon.

When the concentrations of CO2 and H2CO3 are both horizontal lines then the rate of the forward reaction is the same as the rate of the reverse reaction.

<h3>What is rate of reaction?</h3>

The term rate of reaction refers to how fast or slow a reaction proceeds. Recall that the rate  of reaction is measured from the rate of disappearance of reactants or the rate of appearance of products.

When the [CO2] and [H2CO3 ] are both horizontal lines, the rate of the forward reaction is the same as the rate of the reverse reaction.

Let us recall that the reaction is reversible hence addition of H2CO3  will increase the concentration of H2CO3, the reverse reaction would be favored.

A gold nugget has a density of 38.6g/cm3 and a mass of 270.2. what is its volume?​
aivan3 [116]

Density is given by the equation D=m/V, were D is density, m is mass in grams, and V is volume in cubic centimeters.


In this problem, we have density and we have mass so we can plug into the equation and solve for V.

38.6=270.2/V

<em>*Multiply both sides by V*</em>

38.6V=270.2

<em>*Divide both sides by 38.6*</em>

V=7


The volume of the gold nugget is 7cm3.


Hope this helps!!

Bromine is less electronegative than chlorine, yet methyl bromide and methyl chloride have very similar dipole moments. why? sel
diamong [38]
Bromine is less electronegative than chlorine, yet methyl bromide and methyl chloride have very similar dipole moments. This is because the bond distance in methyl bromide is more due to the large size of bromine atom.
Dipole moment is calculated by multiplying the charge on the atom with the bond distance.
