<u>Answer:</u> The molality of magnesium chloride is 1.58 m
<u>Explanation:</u>
To calculate the molality of solution, we use the equation:
Where,
= Given mass of solute (magnesium chloride) = 75.0
= Molar mass of solute (magnesium chloride) = 95.21 g/mol
= Mass of solvent = 500.0 g
Putting values in above equation, we get:
Hence, the molality of magnesium chloride is 1.58 m
Answer:
<em>Dry suction chest tube system</em>
Explanation:
<em>The dry suction drains that are self-regulating today use a small, adjustable regulator installed into the drain. </em>
So long as there is enough air flow from the suction of the wall (that will be shown on the drain) it will respond correctly to changes in the pressure of the source or the patient to retain suction at the drain level.
It's also a quiet mode of activity.
To balance a chemical reaction, it is important to remember that the number of atoms of each element in the reactants and the product side should be equal. This is to follows the law of conservation of mass where mass cannot be created or destroyed. So, the total mass that is used to react should have the same value of the total mass of the substances produced from the reactants. The balanced chemical reaction would be written as follows:
<span> 2h2 + o2 = 2h2o
Reactant = Product
H = 4 = 4
O = 2 = 2
Therefore, the correct coefficient for the hydrogen gas would be 2.</span>
