Answer:
B.) Adhesion
Explanation:
A.) is incorrect. Viscosity is a measure of internal friction that affects the fluidity of a liquid.
B.) is correct. Adhesion is the ability of water to stick to other substances (which are not water).
C.) is incorrect. Surface tension is the tension created by the bonds of the surface particles.
D.) is incorrect. Density is a ratio that compares mass to volume.
The force of the swing.
Hoped I helped, and please tell me if I am wrong.
Answer:
55.9 g KCl.
Explanation:
Hello there!
In this case, according to the definition of molality for the 0.500-molar solution, we need to divide the moles of solute (potassium chloride) over the kilograms of solvent as shown below:
Thus, solving for the moles of solute, we obtain:
Since the density of water is 1 kg/L, we obtain the following moles:
Next, since the molar mass of KCl is 74.5513 g/mol, the mass would be:

For the number less than 0.1 such as 0.006, the zeroes to the right of the decimal point but before the first non zero digit show the decimal place of the first significant digit.
- The number that is given as digits is established using significant figures.
- Any two non-zero digits that are separated by a zero are significant figure.
- Every zero that is both to the right and left of a non-zero digit and the decimal point is not significant figure.
- The quantity of significant figures frequently reveals the degree of measurement accuracy. From the first non-zero digits in the figure, we may determine the number of significant figures.
There is only one significant figure in the provided number 0.06. The decimal place of the first digit is indicated by the zeros that appear to the right of the decimal point but before the first non-zero digit.
