Answer:

H^+(aq) +  OH^-(aq) -------> H2O(l)

Explanation:

We must first write the molecular reaction equation as follows;

HNO3(aq) + NaOH(aq) ------>NaNO3(aq) + H2O(l)

The complete ionic equation is;

H^+(aq) + NO3^-(aq) + Na^+(aq) + OH^-(aq) -------> Na^+(aq) + NO3^-(aq) + H2O(l)

The net ionic equation therefore is;

H^+(aq) +  OH^-(aq) -------> H2O(l)

The density of honey is 1.42 g/mL. If you poured honey into a glass of water, would it sink to the bottom or float on top? Expla
m_a_m_a [10]

Answer:

The honey would sink to the bottom

Explanation:

A simple interpretation of Archimedes' principle is that, in water, the bodys with density lower than that of water will float on top of the water (That is, density <1g/mL). In the other way, a body with density higher than that of water will sink to the bottom.

As density of honey is higher than density of water:

<h3>The honey would sink to the bottom</h3>

What do we mean when we say a chemical reaction is balanced? (Several choices can be correct.)
Rina8888 [55]

Answer:

2 and 3

Explanation:

A chemical reaction is defined as the process in which two or more reactants combined together chemically and gives a different product.

A balanced chemical equation involves an equal number of atoms on the reactant and product side. A balanced chemical reaction occurs when the atoms present on the reactant side or left side of the arrow is equal to the atoms on the product side or right side of the arrow.

The process of the balanced chemical equation is based on errors and trials in which the atoms in each element is identified, the atoms are then multiplied with required numbers, the addition of coefficient in front of molecules and check the equation at last.

Hence, the correct options are "2 and 3".

How many moles are in 7.2 x 10^23 carbon molecules?
choli [55]

Explanation:

It is known that in 1 mole there are 6.023 \times 10^{23} atoms or molecules.

It is given that there are 7.2 \times 10^{23} carbon molecules. Therefore, calculate the moles as follows.

     Number of moles = \frac{7.2 \times 10^{23} molecules}{6.023 \times 10^{23} molecules/mol}

                                   = 1.196 mol

Thus, we can conclude that there are 1.196 mol in 7.2 \times 10^{23} carbon molecules.
