Answer:
b 13kg/m³ is the answer to this question
Binary compounds<span> are easy to </span>name<span>. The cation is always </span>named<span> first and gets its </span>name<span> from the </span>name <span>of the element. For example, K+ is </span>called<span> a potassium </span>ion<span>. An anion also takes its </span>name<span> from its element, but it adds the suffix -ide to it.</span>
Some
of the solutions exhibit
colligative properties. These properties depend on the amount of solute
dissolved in a solvent. These properties include freezing point depression, boiling
point elevation, osmotic pressure and vapor pressure lowering. Calculations
are as follows:
<span>
ΔT(freezing point) = (Kf)mi
3 = 1.86 °C kg / mol (m)(2)
3 =3.72m
m = 0.81 mol/kg</span>
Answer:
two examples are blood and soapy water.
Explanation:
B directly; inversely
Pressure and volume have an inverse relationship (when one increases the other increases) while volume and temperature are direct (if one increases so does the other)
Note: these relationships are only true if other factors are constant such as the temperature, and amount (in moles).
