The formula for specific gravity is:
where is the density of the substance and is the density of water.
The density of water, =
Substituting the values in above formula we get,
The formula of density is:
The density of mercury is
The mass of mercury is
Substituting the values in density formula:
Answer:
A. They both require a human to make them.
Explanation: The main difference between current and charge: Current: It is the rate of flow of charge (generally electrons). Current (I) is the physical quantity measured in amperes (A). Charge: It is the deficiency or excess of electrons on a body surface.
I think the correct answer from the choices listed above is option 3. The atomic mass of an element is defined as the weighted average mass of that element's naturally occurring isotopes. <span>The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu.</span>
The temperature at which the oven it set it should be.
Answer:
The answer to your question is Na₂S, if you need to choices the other one is BaS
Explanation:
As a general rule, all the compounds that have sulfur, are insoluble in water, but the are some exceptions.
-Molecules with ammonia
-If the molecule has alkali metals is soluble
-If the molecule has Ca⁺², Sr⁺² and Ba⁺² is soluble in water.
From the compounds given, following the rules, the compound that is soluble in is Na₂S and perhaps BaS.
