Mass of Oxygen required : 24 grams
<h3>Further explanation</h3>
Given
3 moles of H
1.5 moles of O
3 moles of H₂O
Required
Mass of O
Solution
Reaction
2H₂ + O₂ ⇒ 2H₂O
Mass of Oxygen for 1.5 moles of O :
= mol x Ar O
= 1.5 moles x 16 g/mol
= 24 grams
Answer:
It all depends what your working with and what experiment your planning on doing .
Explanation:
Say if you were working with chemicals you would the tools that would help you protect your body like gloves,googles, apron , etc
So in conclusion it depends what your doing to know what tools you are going to need

The best and most correct answer among the choices provided by the question is the third choice. A theory stating <span>particles of all matter are in constant random motion would be the kinetic theory. I </span><span>hope my answer has come to your help. God bless and have a nice day ahead!</span>
Concentration :
196 g/L and 4 N
<h3> </h3><h3>Further explanation</h3>
The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight / volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.
500 cc of 2M H₂SO₄
V = 500 cc = 0.5 L
mol H₂SO₄
mass H₂SO₄ (MW = 98 g/mol)
concentration in g/L :
concentration in normality
Relationship between normality and molarity
N = M x n (n=valence , amount of H⁺ or OH⁻)
so :
