For a price ceiling to be a binding constraint on the market, the government must set it a above the equilibrium price. b below

beks73 [17]

Answer:

B. Below the equilibrium price

Explanation:Price ceiling is the legal price,impose by The Government or Regulatory agencies above which a product should not be sold. It is also a price control mechanism through which the Government and other Regulatory agencies check the excesses of producers and the middle men(Whole sellers and retailers). The price ceiling has to be fixed below the equilibrium price for it to be binding, because businesses are interested mainly for profit maximization.

How many atoms are there in 3.559*10^-6 mol of krypton?

algol [13]

Answer:

The answer is

<h2> $2.143 \times {10}^{18} \: \: atoms$ </h2>

Explanation:

To find the number of atoms given the number of moles we use the formula

N = n × L

where

N is the number of entities

n is the number of moles

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question

$n = 3.559 \times {10}^{ - 6} \: mol$

Substitute the values into the above formula and solve

That's

<h3> $N = 3.559 \times {10}^{ - 6} \times 6.02 \times {10}^{23} \\ = 2.1425 \times {10}^{18}$ </h3>

We have the final answer as

<h3> $N = 2.143 \times {10}^{18} \: \: atoms$ </h3>

Hope this helps you

a. A solution of potassium dichromate is reduced to chromium(III) ions by zinc metal in the presence of an acid causing the solu

asambeis [7]

Explanation:

It is known that molecular formula of potassium dichromate is $K_{2}Cr_{2}O_{7}$ . As potassium has an oxidation state of +1 and an oxygen atom has an oxidation state of -2.

Let the oxidation state of chromium is x. Therefore, calculate the oxidation state of chromium as follows.

$K_{2}Cr_{2}O_{7}$ = 0 (as the molecule is neutral)

$(2 \times 1) + 2x + (-2 \times 7)$ = 0

2 + 2x - 14 = 0

x = +6

Thus, we can conclude that the oxidation state of the chromium in the potassium dichromate molecule is +6.

Which of the following statements is true? Protons have a mass that contributes significantly to the mass of the atomic nucleus.

Lunna [17]

The following statements from the paragraph are true. Protons have a mass that contributes significantly to the mass of the atomic nucleus. Neutrons have a mass that contributes significantly to the mass of the atomic nucleus. Electrons have a very low mass and are not found in the nucleus but instead are found in surrounding orbits.
