__________ is one of many factors that can determine the rate of alcohol absorption.

12345 [234]

Food consumption affects the rate of alcohol absorption in the bloodstream.

Explanation:

The type of food and therefore the amount of food that is a gift in your epithelial duct once you consume alcohol have the foremost direct impact on the speed of alcohol absorption.

When you consume alcohol on the associate empty abdomen, the alcohol is sometimes absorbed within the blood among fifteen minutes to two-and-a-half hours. If you have got a moderate quantity of food in your abdomen once you drink, that speed slows all the way down to thirty minutes to a few hours. If you’re drinking on a full abdomen, alcohol absorption ranges from 3 to 6 hours.

Write the complete balanced equation for the following reaction:

Assoli18 [71]

Explanation:

An equation that consists of same number of atoms on both reactant and product side is known as a balanced chemical equation.

For example, $C_{7}H_{6}O + O_{2} \rightarrow CO_{2} + H_{2}O$

Number of atoms on reactant side are as follows.

C = 7

H = 6

O = 3

Number of atoms on product side are as follows.

C = 1

H = 2

O = 3

Therefore, to balance this chemical equation we multiply $O_{2}$ by 8 on reactant side. Whereas we multiply $CO_{2}$ by 7 and $H_{2}O$ by 3 on product side.

Therefore, the balanced chemical equation will be as follows.

$C_{7}H_{6}O + 8O_{2} \rightarrow 7CO_{2} + 3H_{2}O$

What is an ion? Describe and give an example.

Goshia [24]

An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom. An example is Iron (III) , Iron (II) , lithium, and hydrogen.

What volume of methane gas at 237 K and 101.33 kPa do you have when the volume is decreased to 0.50 L, with a temperature of 300

Alexxandr [17]

Answer: A volume of 0.592 L of methane gas is required at 237 K and 101.33 kPa when the volume is decreased to 0.50 L, with a temperature of 300 K and a pressure of 151.99 kPa.

Explanation:

Given: $T_{1}$ = 237 K, $P_{1}$ = 101.33 kPa, $V_{1}$ = ?

$T_{2}$ = 300 K, $P_{2}$ = 151.99 kPa, $V_{2}$ = 0.50 L

Formula used is as follows.

$\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}$

Substitute the values into above formula as follows.

$\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}\\\frac{101.33 kPa \times V_{1}}{237 K} = \frac{151.99 kPa \times 0.50 L}{300 K}\\V_{1} = 0.592 L$

Thus, we can conclude that a volume of 0.592 L of methane gas is required at 237 K and 101.33 kPa when the volume is decreased to 0.50 L, with a temperature of 300 K and a pressure of 151.99 kPa.
