A statement which best illustrates the law of demand is: (d) Sue wants to buy more candy bars at $1 than at $2.
<h3>What is the
law of
demand?</h3>
The law of demand is an economic theory which states that there exist a negative relationship between the price of a product (good) and the quantity of the product (good) that is being demanded by consumers.
This ultimately implies that, there would be a significant decline (fall) in the demand for a product (good) and service when the price of a product (good) and service in the market increases (rises).
In this context, we can infer and logically deduce that a statement which best illustrates the law of demand is stating that Sue wants to buy more candy bars at a price of $1 rather than at price of $2.

At constant temperature, if the pressure of the sample of the krypton gas increases to the given value, the volume decreases to 15mL.
<h3>What is Boyle's law?</h3>
Boyle's law simply states that "the volume of any given quantity of gas is inversely proportional to its pressure as long as temperature remains constant.
Boyle's law is expressed as;
P₁V₁ = P₂V₂
Where P₁ is Initial Pressure, V₁ is Initial volume, P₂ is Final Pressure and V₂ is Final volume.
Given the data in the question question;
- Initial volume of the gas V₁ = 75.0mL = 0.075L
- Initial pressure of the gas P₁ = 0.40atm
- Final pressure of the gas P₂ = 2.00atm
- Final volume of the gas V₂ = ?
Now, we substitute our given values into the expression above to determine the new volume of the krypton gas.
P₁V₁ = P₂V₂
V₂ = P₁V₁ / P₂
V₂ = 0.40atm × 0.075L / 2.00atm
V₂ = 0.03Latm / 2.00atm
V₂ = 0.015L
V₂ = 15mL
Therefore, at constant temperature, if the pressure of the sample of the krypton gas increases to the given value, the volume decreases to 15mL.

The mass of hydrogen in 57.010 g ammonium hydrogen phosphate, (NH₄)H₂PO₄ is 2.97 g
<h3>Determination of mass of 1 mole of (NH₄)H₂PO₄ </h3>
1 mole of (NH₄)H₂PO₄ = 14 + (4×1) + (2×1) + 31 + (16×4) = 115 g
<h3>Determination of the mass of H in 1 mole of (NH₄)H₂PO₄ </h3>
Mass of H = 6H = 6 × 1 = 6 g
<h3>Determination of the mass of H in 57.010 g of (NH₄)H₂PO₄ </h3>
115 g of (NH₄)H₂PO₄ contains 6 g of H.
Therefore,
57.010 g of (NH₄)H₂PO₄ will contain = (57.010 × 6) / 115 = 2.97 g of H
Thus, 2.97 g of Hydrogen, H is present in 57.010 g of (NH₄)H₂PO₄
