What are the Respiration effects on the pH?

1 answer:

3 0

Our blood have a pH around the 7.0, when we hold the breath our cells still breathing, and the release $CO_2$ , this compound react with water (hydrolysis).

$H_2O+CO_2\leftrightharpoons H_2CO_3$

This compound formed by this reaction is acid, carbonic acid.

Them the pH will get lower them normal, and our buld send an action to our body, and this reaction will be the <span>breathing.</span>

How many moles of aspartame are present in 1.00 mg of aspartame?

Diano4ka-milaya [45]

Answer:- There are $3.40*10^-^6$ moles.

Solution:- It is a unit conversion problem where we are asked to convert mg of aspartame to moles. Aspartame is $C_1_4H_1_8N_2O_5$ and it's molar mass is 294.31 grams per mole.

mg are converted to grams and then the grams are converted to moles as:

$1.00mg Aspartame(\frac{1g}{1000mg})(\frac{1mole}{294.31g})$

= $3.40*10^-^6$ moles of aspartame

So, there would be $3.40*10^-^6$ moles of aspartame in 1.00 mg of it.

An air compressor takes atmospheric air (think about what pressure it is at) and pressures it up to 68 (psig). In the process, i

Aleks [24]

Answer:

5.19 m³

Explanation:

Data Given:

initial Pressure P1 = atmospheric pressure

Reported atmospheric pressure = 14.696 psi

Final pressures P2 = 68 psi

initial Temperature T1 = 26 °C

final Temperature T2 = 48 °C

initial Volume V1= 13 m³

final Volume V2 = ?

Solution:

Formula will be used

P1 V1 / T1 = P2 V2 / T2

To calculate volume rearrange the above formula

V2 = (P1 V1) T2 / T1 P2 . . . . . . . .(1)

put values in equation 1

V2 = (14.696 psi x 13 m³) 48 °C / 26 °C x 68 psi

V2 = (191.05 psi m³) 48 °C / 1768 °C psi

V2 = (9170.3 psi m³ °C / 1768 °C psi

V2 = 5.19 m³

So, final volume is 5.19 m³

In boyle's law, the initial volume of a gas is 120 ml at 256 kpa. what will be the volume if the pressure increases to 385 kpa?

Vinil7 [7]

<h3>Answer:</h3>

79.8 ml

<h3>Explanation:</h3>

Boyle's law describes the relationship between pressure and volume when the temperature is constant. For this question, I will be rounding to significant figures.

Boyle's Formula

When describing the relationship between pressure and volume, the formula $\displaystyle P_{1} V_{1}= P_{2} V_{2}$ . In this formula, $P_{1}V_{1}$ is the initial pressure and volume. On the other side, $P_{2} V_{2}$ is final pressure and volume. So, to find a missing variable you must plug in the values you are given.
