Answer: el estudio de la síntesis, estructura, reactividad y propiedades del diverso grupo de compuestos químicos construidos principalmente de carbono
Explanation:Hope I helped:)
This reaction would produce salt and water- Sodium Sulphate and Water.
H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O
Talking about ions, a cation has a positive charge. That means a positive charge is gained by an atom that gives out electrons.
The mass of water in the tank, given the data from the question is 549594 g
<h3> Description of mole </h3>
The mole of a substance is related to it's mass and molar mass according to the following equation:
Mole = mass / molar mass
<h3>How to determine the mass of water in the tank</h3>
From the question given above, the following data were obtained:
- Mole of water = 30533 moles
- Molar mass of water = 18 g/mol
- Mass of water = ?
The mass of the water can be obtained as follow:
Mass = mole × molar mass
Mass of water = 30533 × 18
Mass of water = 549594 g

Answer:
0.9 mol/L.
Explanation:
- Molarity is defined as <em>the number of moles of solute in a 1.0 L of the solution.</em>
- It can be expressed as: <em>M = n / V(L)</em>
M is the molarity of the solution <em>(mol/L)</em>,
n is the number of moles of solute <em>(n = 4.5 moles)</em>,
V is the volume of the solution <em>(V = 500 ml = 0.5 L)</em>.
- ∴ The molarity of the solution (M) = n / V = (4.5 mol) / (0.5 L) = 0.9 mol/L.
