Answer:
matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.

Explanation:
Orifice meters require to compensate for pressure and temperature when one uses these meters to measure the steam or the gas flow in the pipes with the variable operating pressure as well as temperature conditions.
Normally chemists do not have online density measurement tool and thus to avoid complications, the chemists consider density as constant parameter.
<u>In the steam or the gas flow measurement, density of steam or gas changes as the pressure and the temperature change. This significant change in the density can affect accuracy of measured flow rate if the change is uncompensated and thus, this has to be fixed in order to avoid errors.</u> Therefore, it is important to compensate for the pressure and the temperature when orifice is used to measure the steam or the gas flow.
Answer:
water pulling a compound apart and then surrounding the broken pieces/ions (this is what dissolving is)
Explanation:
As we know, water is a polar solvent. What this means is that water can effectively interact with ions in an ionic substance owing to its large dipole moment.
Now, when an ionic substance is dissolved in water, the positive end in water pulls hard on the negative ion of the ionic substance while the negative end in water pulls hard on the positive ion of the ionic substance.
The ionic substance is eventually pulled apart and surrounded by water molecules. This is how an ionic substance is dissolved in water.
