Answer
is: 1) ccl4, kb = 29.9°c/m, carbon tetrachloride has the greatest boiling point
elevation.
The boiling point elevation is directly
proportional to the molality of the solution according to the
equation: ΔTb = Kb · b.
<span>
ΔTb - the boiling point
elevation.
Kb - the ebullioscopic
constant.
b - molality of the solution.
So the highest boiling poing elevation will be for solution with highest ebullioscopic constant because molality is the same.</span>
Answer:
The dispersed particles are spread evenly throughout the dispersion medium, which can be a solid, liquid, or gas. Because the dispersed particles of a colloid are not as large as those of a suspension, they do not settle out upon standing.
Explanation:
Answer:
247 ml
Explanation:
How many mL of 0.150 M HF solution are required to produce 0.0370 moles of HF 0.150 moles/ liter = 0.150/1000 moles/ml =0.000150 moles/ml
0.000150 x ? = 0.0370 moles HF
? = 0.0370/0.000150 = 247 ml
check
247 ml = 247/1000 L = 0.247
(0.247) x (0.150) =0.370 check
Answer:
It would be thermal energy.
Explanation:
Thermal energy is the energy transfer of heat which is created while doing physical activity.
Here we have to chose the correct statement which affect the discovery of the atomic number on the periodic table.
The discovery of the atomic number of the elements: C. It allowed the elements to be placed in strict order of increasing atomic number.
The use of X-ray determined the atomic number or number of electrons present in an element. The number of electrons is the basis of generate the periodic table, where the elements are arranged in terms of the number of electrons present in the atom in early stage of periodic table.
However in later the modern periodic table generated, which has group and period in terms of their property. Although the strictness on the increasing number of electrons are followed.
