Answer:
When comparing propionic acid (CH₃CH₂COOH) and sodium propionate (CH₃CH₂COONa), the one that is more soluble in water sodium propionate.
When comparing cyclohexane (C6H12) and glucose (C6H12O6), the one that is more soluble in water is glucose
When comparing hydrochloric acid (HCl) and ethyl chloride (CH3CH2Cl), the one that is more soluble in water is hydrochloric acid
Explanation:
When comparing propionic acid (CH₃CH₂COOH) and sodium propionate (CH₃CH₂COONa), the one that is more soluble in water sodium propionate. Because always a salt is more soluble in water than its acid (Solubility of propionic acid is 0,37g/mL and of sodium propionate is 1g/mL).
When comparing cyclohexane (C6H12) and glucose (C6H12O6), the one that is more soluble in water is glucose because cyclohexane is made from petroleum and its polarity is very low (cyclohexane is insoluble in water and solubility of glucose is 0,91g/mL).
When comparing hydrochloric acid (HCl) and ethyl chloride (CH3CH2Cl), the one that is more soluble in water is hydrochloric acid because an acid has a medium-high solubility in water but, again, an alkane derived from petroleum has very low solubility in water (hydrochloric acid has a solubility of 0,823g/mL and ethyl chloride is insoluble in water).
I hope it helps!
Answer: The correct number of significant figures in is 35.05152.
Explanation:
Digits present in a number that helps in determining the degree of accuracy starting from the first non-zero digit is called a significant figure.
Some rules for significant figures are as follows.
- All the digits present within the non-zero digits are considered in a number.
For example, 2085 contains 4 significant digits.
- Leading zeros are not counted in a number.
For example, 0.0034 has 2 significant digits.
- We count the trailing zeros when a decimal point is present in a number.
For example, 0.02500 has 4 significant figures.
- When there is no decimal point then trailing zeros may or may not count.
For example, 19000 has 2 significant digits.
Now, the product of given digits is as follows.
Thus, we can conclude that correct number of significant figures in is 35.05152.
Answer:Therefore, there must be a direct relationship between these volumes of gases and the number of molecules they contain. Avogadro's law says that: Equal volumes of different gaseous substances, measured under the same pressure and temperature conditions, contain the same number of molecules.
