if 150g of aluminum react with 101g of sulfuric acid what is the maximum amount of hydrogen gas that can be produced

1 answer:

4 0

2Al + 3H2SO4 -> 3H2 + Al2(SO4)3

First, find your limiting reactant - do this with your moles.

Have:
Al - 5.559mol
H2SO4 - 1.030mol
Need:
Al - 0.6867mol
H2SO4 - 8.339mol

Your limiting reactant is sulfuric acid, so we will use that.

Use your mole bridge and the calculated HAVE of sulfuric acid to do this.

1.030mol * (3/3) = 1.030mol of H2

If you want it in liters, multiply that by 22.4dm^3. If you want it in grams, multiply it by 2.016. Hope this helps!

Which of the following is an acceptable IUPAC name?(A) 3,6-dimethylheptane (B) 2-ethyl-3-methylheptane (C) 5-methyl-3-ethylhepta

bearhunter [10]

Answer:

D) 4-ethyl-4-methylheptane

Explanation:

The rules for naming of alkanes with substituents.

1. The carbon chain with the maximum number of carbon atoms must be selected as a parent chain.

2.Numbering should be done in such a way that each substituent gets the least number.

3. Substituents whose name comes before the another substituents's name in the English alphabet is written first.

4. Substituents are written first with their location in the chain and the name of the parent chain is done. Numbers are separated from numbers by comma and numbers are separated from letters by using hyphen.

Considering (a) 3,6-dimethylheptane

Violation of Rule - 2 mentioned above

The numbering of the parent chain is not done in a right way. Numbering must be done such that each substituent gets the least number. So, The correct name is 2,5-dimethylheptane

Considering (b) 2-ethyl-3-methylheptane

Violation of Rule - 1 mentioned above.

The carbon chain with the maximum number of carbon atoms must be selected as a parent chain. The parent chain selected is of 7 carbon atoms but the parent chain is of 8 carbon atoms. So, The correct name is 3,4-dimethyloctane

Considering (c) 5-methyl-3-ethylheptane

Violation of Rule - 3 mentioned above.

'e' comes before 'm' . So, ethyl- is written first than methyl- . So, The correct name is 3,6-dimethyloctane

Considering (d) 4-ethyl-4-methylheptane

This is a IUPAC name and following all the rules mentioned above.

What is the molar concentration of hydronium ions in a sample of a soft drink that has a ph of 4?

hammer [34]

[ $H^{+}$ ] value of soft drink is 0.0001mol/l when given pH is 4.

Given:

pH = 4

Needs to find: [ $H^{+}$ ]

Formula to find: pH=−log $_{10}$ [ $H^{+}$ ]

We can put the values of pH in above formula as,

pH=−log $_{10}$ [ $H^{+}$ ]

4 =−log $_{10}$ [ $H^{+}$ ]

To calculate hydonium ion concentration, formula is as follows;

[ $H^{+}$ ] = $10^{-pH}$

[ $H^{+}$ ] = $10^{-4}$ = 0.0001mol/l

[ $H^{+}$ ] value of soft drink is 0.0001mol/l

If an element has 11 protons and 11 neutrons in its nucleus it must be ?

Juliette [100K]

Answer:

the answer is 11

Explanation:

Ok, let us understand what is an atomic number, an atomic number is simply the proton number, the atomic number is always seen at the bottom left corner in a element of a periodic table, it is the number of proton in a atom of a certain element.
