A chemist is using a solution of hno3 that has a ph of 3.75. what is [h ] for the solution?
kap26 [50]

A chemist is using a solution of HNO₃ that has a pH of 3.75. what is [H⁺] for the solution is 1.7 × 10⁻⁴M.

<h3>How do we calculate the [H⁺]?</h3>

Concentration of H⁺ ion will be calculated by using the below equation of pH as:

pH = -log[H⁺]

or [H⁺] = 10^{-pH}

Given that, pH = 3.75

So concentration of H⁺ ion will be calculated as:

[H⁺] = 10^{-3.75}

[H⁺] = 1.7 × 10⁻⁴M

Hence concentration of H⁺ ion is 1.7 × 10⁻⁴M.

What mass of carbon dioxide is produced from the complete combustion of 4.50×10−3 g of methane?
ivanzaharov [21]

CH₄ + 2O₂ → CO₂ + 2H₂O

From the equation, we know that methane and carbon dioxide have the same number of moles.

no. of moles = \frac{mass}{molar mass}

no. of moles of CO₂ produced = no. of moles of methane

= 4.5 × 10⁻³ ÷ (12 + 1×4)

= 2.8125 × 10⁻⁴

∴ mass of CO₂ = 2.8125 × 10⁻⁴ × (12 + 16×2)

= 12.375 × 10⁻³ g

How do electrons affect the state of an element?
olya-2409 [2.1K]

Answer:

Explanation:

All matter is made up of atoms. ... These shells are actually different energy levels and within the energy levels, the electrons orbit the nucleus of the atom. The ground state of an electron, the energy level it normally occupies, is the state of lowest energy for that electron.
