Answer:
Answer the first ine made up of 2 or more.....
Answer: Volume required is 0.115 L or 115 ml
Explanation:
moles of =
The balanced chemical equation is:
1 mole of requires = 1 mole of HCl
Thus 0.015 mol of requires = mole of HCl
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in L
Thus volume required is 0.115 l or 115 ml
When something radiates, it sends out waves or rays. ... If your house has a radiator, that might help you remember this word, because the radiator radiates warmth. Radiating is a concept that applies to anything that emits rays or waves. People camping make a fire so it can radiate light and heat.
The change of energy : 4.8744 x 10⁺¹⁹ J
<h3>Further explanation</h3>
Radiation energy is absorbed by photons
The energy in one photon can be formulated as
Where
h = Planck's constant (6,626.10⁻³⁴ Js)
f = Frequency of electromagnetic waves
f = c / λ
c = speed of light
= 3.10⁸
λ = wavelength
The wavelength is 4078 A = 4.078 x 10⁺⁷ m
