Answer:

1 200 000 000 000 000 000 000 000 H⁺ ions

Step-by-step explanation:

Assume that the concentration of H⁺ ions in stomach ions is <em>2.0 mol·L⁻¹.</em>

Then, we have 2.0 mol of H⁺ ions

There are 6.02 × 10²³ H⁺ ions in 1 mol.

2.0 mol = 2.0 × 6.022 × 10²³/1

             = 1.2 × 10²⁴ H⁺ ions

             = 1 200 000 000 000 000 000 000 000 H⁺ ions

Calculate the enthalpy change when 4.00 mol Cl2O7 is produced according to the following balanced equation:
marissa [1.9K]

So the equation is,

2Cl2(g) + 7O2(g) + 130kcal -> 2Cl2O7(g)

from this , ΔH°rxn=130kcal.mol^{-1}

mol^{-1} is mentioned because it is for per mole of reaction. So for 4. moles of the product 2Cl_{2} O_{7} we need 4/2 moles of reaction to be used to calculate associated enthalphy change for the reaction.

Therefore4/2*130=260 kcal

How many moles of H2O<br> moles of H2O are needed to produce 55.7 moles of H2?
Fofino [41]

<u>Answer:</u> 55.7 moles of H_2O are needed to produce the given amount of H_2

<u>Explanation:</u>

The number of moles is defined as the ratio of the mass of a substance to its molar mass.

The equation used is:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}} ......(1)

Given values:

Moles of H_2 = 55.7 moles

The chemical equation for the decomposition of water follows:

2H_2O\rightarrow 2H_2+O_2

By the stoichiometry of the reaction:

If 2 moles of hydrogen gas is produced from 2 moles of water

So, 55.7 moles of hydrogen gas will be produced by = \frac{2}{2}\times 55.7=55.7mol of water

Hence, 55.7 moles of H_2O are needed to produce the given amount of H_2

Which of the following you do NOT need to pay attention while using a centrifuge?
Phoenix [80]

Answer:

The radius of the centrifuge.

Explanation:

Hello,

Since the radius of the centrifuge is just a design parameter, it wouldn't be a cause of failure because it is used to know how many tubes could be fitted in into the centrifuge. On the other hand, keeping you attention away from other factors could turn into a failure as long as the sample could be poured down or just turn out inadequate for the expected results.

Best regards.
