Answer:
Relative humidity is low .
Explanation:
The wet bulb reads low temperature because due to low humidity of atmosphere , evaporation of water takes place from the wet bulb which makes the bulb cool and therefore it reads lower temperature . In the process of evaporation , heat equal to latent heat of vaporization is taken from the bulb and it loses temperature.
Answer:
The Empirical Formula.
Explanation:
From the empirical formula and using the weight (in g) of a given substance, we can come up with the molecular formula which is the actual weight of a substance. Sometimes, we find that the empircal formula is the molecular formula.
Answer:
CaCO3
Explanation:
The molecule is formed by the calcium cation Ca+2 and the carbonate anion CO3−2.
Answer:
2.35 x 10²⁰ atoms Ga
Explanation:
After converting from mg to g, use the molar mass as the unit converter to convert to moles. Then using Avogadro's number, 6.022 x 10²³ convert from moles to atoms of Ga.
Then round to 3 significant figures = 2.35 x 10²⁰ atoms Ga.
Answer:
C. The lowest whole-number ratio of atoms in a molecule.
Explanation:
Hello there!
In this case, according to the definition of the empirical and the molecular equations, it is possible for us to consider the following example of molecular formula, C4H10, whose empirical formula is C2H5.
In such a way, it is possible for us to say that the empirical formula gives C. The lowest whole-number ratio of atoms in a molecule, as it is the result of the simplification of the molecular formula when possible.
Regards!
