The number of mole of solute particles are present in 1 mL (exact) of aqueous 0.0040 M Ba(OH)₂ is 0.000004 mole
<h3>What is molarity? </h3>
Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:
Molarity = mole / Volume
With the above formula, we can determine the number of mole present in the solution. Detail below:
<h3>How to determine the mole of the solute in the solution</h3>
- Volume of solution = 1 mL = 1 / 1000 = 0.001 L
- Molarity of solution = 0.004 M
- Mole of solute =?
Molarity = mole / Volume
Cross multiply
Mole = Molarity × volume
Mole of solute = 0.004 × 0.001
Mole of solute = 0.000004 mole
Thus, the mole of the solute in the solution is 0.000004 mole

Answer:
a relief valve is inserted in the downstream line from the pressure regulator.
Explanation:
Whenever dry nitrogen from a portable cylinder is used in service and installation practice the item of most importance in consideration of safety is a relief valve is inserted in the downstream line from the pressure regulator.
Answer:
Heat
Explanation:
Energy exchange occurs when two systems exchange energy between them, or a system exchange energy with its surroundings. This phenomenon can happen in two ways: heat or work.
The heat is the exchange of energy caused by the difference in temperature. So, when the systems lose heat, its temperature decreases, and when it gains heat, its temperature increases.
The work is the energy exchange caused by the difference in volume and pressure. When a gas expands, its volumes increase, and it does work to its surroundings. When it compresses, its volumes decrease and it suffers work from its surroundings.
So, when the wax melt, the temperature of it must have increased, and it has gained heat. The energy exchange as heat.
An acid is a molecule or ion capable of either donating a proton, known as a acid, or, capable of forming a covalent bond with an electron pair, The first category of acids are the proton donors.
