Given parameters:

Mass of rock = 14g

Volume of rock = 12cm³

Unknown:

Density of the rock = ?

Density of a substance is the amount of substance it contains per unit volume. Mathematically, this can be expressed as;

Density = $\frac{Mass}{Volume}$

Now simply input the parameters and solve;

Density = $\frac{14}{12}$ = 1.17g/cm³

Density of the rock that Jack has is 1.17g/cm³

What is the limiting reactant if 12 moles of p4 react with 15 moles of o2?.

brilliants [131]

Answer:

see explanation

Explanation:

To determine limiting reactant divide mole quantities of reactants by the respective coefficient in the balanced equation. The smaller value is the limiting reactant.

P₄ + 5O₂ => 2P₂O₅

12/1 = 12 15/5 = 3

O₂ is the limiting reactant. P₄ will be in excess when rxn stops.

Find the [H+] in an acetic acid solution that has a pH of 5.12

Eva8 [605]

<span>Data:
pH = 5.2
[H+] = ?

Knowing that: (</span><span>Equation to find the pH of a solution)</span>
$pH = -log[H+]$
<span>
Solving:
</span> $pH = -log[H+]$
$5.2 = - log [H+]$
Knowing that the exponential is the opposite operation of the logarithm, then we have:
$[H+] = 10^{-5.2}$
$\boxed{\boxed{[H+] = 6.30*10^{-6}}}\end{array}}\qquad\quad\checkmark$
