Answer:

1) False

2) there are equal amounts of rectants and products

Explanation:

1)  When dynamic equilibrium is achieved. the rate of forward and backward reaction they are the same, that is to say, two opposite reactions occur at the same rate, keeping the concentrations constant over time.  Different to say the rate of the ractions go to zero.

2)  A chemical equilibium exists when what is produce in quantities is equal to what reacts.

So the correct answer is the literal (d).

Answer:

1. Exothermic reaction

2. Is being released

3. The energy comes from the change in energy between reactants and products

Explanation:

The reaction is producing energy. A reaction that produce energy is called a <em>Exothermic reaction.</em>

<em />

As the energy is produced, the energy is being <em>released.</em>

<em />

As you can see in the image, the energy of the reactants is higher than the energy of the products. This change of energy in the chemicals produce the production of energy as heat.

How do subscripts represent the charge balance of ions
finlep [7]
<h3><u>Answer and explanation</u>;</h3>
  • To balance the charges of ions the number of electrons lost is equal to the number of electrons gained. The overall net charge must be zero.
  • The number of ions needed to accomplish this is represented by the subscripts.
  • For any given ionic compound, the product of the charge on the ion (or multiatomic ionic group) times the subscript of the ion will give a total charge of zero when all ions are considered.

For examples: NaCl Na = +1 Cl = -1 total is zero

What devices will you use to measure the mass and the volume in this experiment? (density)
bekas [8.4K]

Answer:

Methods for determining or delivering precise volumes include volumetric pipets and pycnometers; less precise methods include burets, graduated cylinders, and graduated pipets. In this experiment, you will measure masses and volumes to determine density. Four different metal cylinders are investigated.
