Answer:

There is no net ionic equation

Explanation:

Step 1: Data given

sodium cyanide = NaCN

nitric acid = HNO3

sodium nitrate = NaNO3

hydrocyanic acid = HCN

Step 2: The unbalanced equation

NaCN(aq) + HNO3(aq) → NaNO3(aq) + HCN(aq)

The equation is already balanced.

Step 3: the net ionic equation

The net ionic equation, for which spectator ions are omitted - remember that spectator ions are those ions located on both sides of the equation - will , after canceling those spectator ions in both side, look like this:

Na+ + CN- + H+ NO3-   → Na+ + NO3- + H+ + CN-

There is no net ionic equation

If you don't have a net ionic equation to balance, that means you have what is usually called a molecular equation (or a complete molecular equation)

Answer:

There is no net ionic equation

Explanation:

We identify the reactants and the products for the reaction

NaCN, HNO₃, NaNO₃, HCN

In this case, they are all soluble in water (aq)

We write the reaction, by the ionic form

Na⁺(aq) + CN⁻ (aq) + H⁺ (aq) + NO₃⁻(aq)  → Na⁺(aq) + NO₃⁻(aq)  + H⁺(aq) + CN⁻(aq)

All of the ions are spectators, they all react so there is no net ionic equation

The average rate of disappearance of ozone in the reaction 2o3(g) → 3o2(g) is found to be 7.25×10–3 atm over a certain interval
worty [1.4K]
<h3><u>Answer</u>;</h3>

1.0875 x 10-2 atm

<h3><u>Explanation;</u></h3>

2O3(g) → 3O2(g)

rate = -(1/2)∆[O3]/∆t = +(1/3)∆[O2)/∆t  

The average rate of disappearance of ozone ... is found to  

be 7.25 × 10–3 atm over a certain interval of time.

This means (ignoring time)

∆[O3]/∆t = -7.25 × 10^–3 atm  

(it is disappearing, thus the negative sign)

rate = -(1/2)∆[O3]/∆t  

rate = -(1/2)*(-7.25 × 10^–3 atm)

      = 3.625 × 10^–3 atm  

Now use the other part of the expression:  

rate = +(1/3)∆[O2)∆t  

3.625 × 10–3 atm = +(1/3)∆[O2)/t  

∆[O2)/∆t = (3)*(3.625× 10^–3 atm)

              = 1.0875 x 10-2 atm over the same time interval

You have a graduated cylinder with 10 mL of water in it.
Law Incorporation [45]

Answer:

<h3>The answer is 10 g/mL</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 300 g

volume = final volume of water - initial volume of water

volume = 40 - 10 = 30 mL

We have

density =  \frac{300}{30}  =    \frac{30}{3}  \\

We have the final answer as

<h3>10 g/mL</h3>

Hope this helps you

Which of these solid compounds are most likely to have its dominant bonding mechanism as covalent? (Select all that are true.)
I am Lyosha [343]

The compounds that have covalent bonding as their dominant bonding scheme are diamond and silica.

A covalent bond is formed between two nonmetals. Usually, when two nonmetals combine, electrons are shared between the two atoms involved in the bond.

Now, the solids diamond and silica are predominantly covalent solids. The atoms that combine in diamond are carbon atoms(nonmetals) while the atoms that combine in silica are silicon and oxygen (nonmetals also)

Hence, diamond and silica both have covalent bonding as their dominant bonding scheme.
