Answer:
pH = 4.7
Explanation:
The pH is a measurement of acidity using the concentration of hydrogen ions (H⁺) in a solution. Therefore, before you can find the pH, you need to determine the concentration (M) of H⁺ in the solution. This can be done by multiplying the molarity of the solution by the amount of H⁺ in the solution.
1 mole H₂SO₄ = 2 moles H⁺ and 1 mole SO₄⁻
1.0 x 10⁻⁵ M H₂SO₄ 2 moles H⁺
----------------------------- x ---------------------- = 2.0 x 10⁻⁵ M H⁺
1 mole H₂SO₄
To find the pH, you need to use the following equation:
pH = -log[H⁺]
Since you calculated the hydrogen concentration ([H⁺]) in the previous step, you can plug it into the equation and solve.
pH = -log[H⁺]
pH = -log[2.0 x 10⁻⁵]
pH = 4.7
The answer is A because it gets caught in clouds then is let down in rain
The answer is A since I looked it up :)
Answer:
limiting Reactant
Explanation:
In a chemical reaction, the limiting reagent, or limiting reactant, is the substance that has been completely consumed when the chemical reaction is complete.
Protons and neutrons are made up of tiny particles called quarks.
A proton is a baryon made up two Up and one Down quark.
A neutron is made of two Down quarks and one Up quark.
The Up quarks possess a 2/3 positive charge while the Down quark possess a 1/3 negative charge.
When we refer that a proton consists of two Up quarks and a Down, this simply means that its net appearance matches this description.
It is thought that quarks themselves are surrounded by gluons.
Gluons are the basic particles underlying the strong interaction between protons and neutrons in the nucleus.
