Answer:
1M
Explanation:
First, let us write a balanced equation for the reaction. This is illustrated below:
NaOH + HCl —> NaCl + H2O
From the equation above,
nA (mole of acid) = 1
nB (mole of the base) = 1
Data obtained from the question include:
Vb (volume of base) = 50mL
Mb (Molarity of base) = 0.2M
Va (volume of acid) = 10mL
Ma (Molarity of acid) =?
Using MaVa/MbVb = nA/nB, we can calculate the molarity of the acid as follow:
Ma x 10/0.2 x 50 = 1
Cross multiply to express in linear form
Ma x 10 = 0.2 x 50
Divide both side by 10
Ma = (0.2 x 50)/10
Ma = 1M
The molarity of the acid is 1M
Answer:
Molecular formula = C₁₀H₂₀
Explanation:
Given data:
Empirical formula = CH₂
Molar mass = 140.27 g/mol
Molecular formula = ?
Solution:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Now we will calculate the empirical formula mass.
CH₂ = 12 × 1 + 1× 2
CH₂ = 12 +2
CH₂ = 14
n = 140.27 / 14
n = 1
0
Molecular formula = n (empirical formula)
Molecular formula = 10 (CH₂)
Molecular formula = C₁₀H₂₀
Answer:
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.
