The volume of a solid is measured in cubic units i.e. cubic centimeter, cubic meter, cubic feet etc.
Answer:
H₂O, Na⁺, and SO₄²⁻
Explanation:
NaOH and H₂SO₄ are strong electrolytes. They will ionize completely
.
Molecular equation: 2NaOH + H₂SO₄ ⟶ Na₂SO₄ + 2H₂O
Ionic equation: 2Na⁺ + 2OH⁻ + 2H⁺ + SO₄²⁻ ⟶ 2Na⁺ + SO₄²⁻+ 2H₂O
- The concentration of water is 55.5 mol·L⁻¹.
- The concentration of Na⁺ is twice that of SO₄²⁻ .
- Hydrolysis of SO₄²⁻ is negligible.
The principal components in the flask at the endpoint are H₂O, Na⁺, and SO₄²⁻.
You can explain what it means...like how gas tends to expand when heated and just tie it up with the sentence you want to make....(i dont know if that was helpful?)
Answer:
Mass = 684.2 g
Explanation:
Given data:
Moles of Aluminium = 25.36 mol
Mass of Al = ?
Solution:
Formula:
Number of moles = mass/ molar mass
Mass = number of moles × molar mass
Molar mass of Aluminium = 27 g/mol
Now we will put the values:
Mass = 25.36 mol × 26.98 g/mol
Mass = 684.2 g
D. 2,3,4-trimethylpentane
