Answer:
true
Explanation:
i took the quiz :) so i hope this helps
Particles of gas are more scarcely placed as compared to that of liquid.
the intermolecular forces will be less in gaseous state and hence is less stable
Because if they aren't properly included, it means that you are saying that the numbers can be anything, all reals.
Not including units is the same thing, if you don't properly lable the data table, you could be talking about anything.
Not giving a proper unit/variable is almost like giving someone permission to assume what you're talking about
<h3>Answer:</h3>
221.90 g.mol⁻¹
<h3>Explanation:</h3>
The mass of contained by a molecule is known as molecular mass. It is the sum of atomic weights of the elements contained by the molecule. In given case Iodine Pentafluoride has a chemical formula,
IF₅
The atomic weights of each element are as;
Iodine = 126.90 g.mol⁻¹
Fluorine = 19.00 g.mol⁻¹
As there are five atoms of Fluorine so, we will multiply the atomic weight of Fluorine by five and that of Iodine by one as there is only one Iodine atom.
Therefore,
Molecular Mass of IF₅ = (1 × 126.90 g.mol⁻¹) + (5 × 19.00 g.mol⁻¹)
Molecular Mass of IF₅ = (126.90 g.mol⁻¹) + (95.00 g.mol⁻¹)
Molecular Mass of IF₅ = 221.90 g.mol⁻¹
I think the correct answer among the choices listed above is the third option. Sodium and potassium are the substances that are lost when the body perspires. These substances are dissolved in the sweat you are excreting when you are doing physical activities.
