Balanced equation first.
2Al + 6HCl >> 2AlCl3 + 3H2
(find limiting reactant )
5 mole Al (6 mole HCl/2mole Al) = 15 mole HCl
5 mole HCl (2 mole Al/6 mole HCl) = 1.7 mole Al
( Al looks short of what is required, so will drive reaction )
5 moles Al (3 moles H2/2 moles Al)
= 7.5 moles of H2 produced.
Balanced equation first.
Cl2 + H2 >> 2HCl
Now use PV = nRT to find moles Cl2 as this limits and drives reaction.
(1 atm)(5.00 L) = n(0.08206 Latm/molK)(298.15 K)
= 0.204 moles Cl2 ( now use stoichiometry )
0.204 moles Cl2 (2mole HCl/1 mole Cl2)
= 0.408 moles HCl produced
The reaction between HCl & Al will be follow as :
6HCl + 2Al = 2AlCl3 + 3H2
Now 2 mole of Al reacts with = 6 moles of HCl
Then 0.06591 moles of Al will react with = 3X0.06591 = 0.19773 mole of HCl

The empirical formula for aluminum chloride is AlCl3, and its gram formula mass is 133.34. The formula shows that each formula unit contains one aluminum atom, and the the gram atomic mass of aluminum is 26.9815. Therefore, 18(133.34/26.9815) or 89 grams, to the justified number of significant digits, of aluminum chloride will be produced.
This is a mole stoichiometry problem. Start with the balanced equation for the synthesis of aluminum oxide: 4Al + 3O2 --> 2Al2O3. The ratio of aluminum to aluminum oxide in this equation is 4:2, or 2:1, so 5.23 moles Al means half that number for Al2O3, so about 2.62 moles of aluminum oxide will be produced.
Hydrogen's atomic number is 1.
The mass number of the most common hydrogen isotope, Hydrogen-1, is one
The atomic number of hydrogen is 1.
The element with the atomic number 13 is aluminum.
Hydrogen is a non metal element. Mass number of it is 1.
Because the number of positive hydrogen ions produced is equal to the number of negative ions produced, water is neutral. Water is neutral despite the production of hydrogen ions and hydroxide ions because the number of positive hydrogen ions produced is equal to the number of negative ions produced, water is neutral.
Hydrogen is the chemical element with atomic number 1, symbol H. In 1783 it was given its name when it was discovered that water is produced when hydrogen is burned.
pure water is neutral with a pH of 7

You have to calculate the number of picometers in one meter. Then you have to use the formula for conversion of the foot to meter. Then calculate the answer.
Steps to take: Write the chemical formula : Al2O3 Calculate the number of moles for aluminum oxide. You should know the formula which is the mass given (0.051g) divided by the Mass of aluminum oxide. Since there is '2' moles of Aluminium you multiplly the number of moles calculated for aluminum oxide by 2. Then you have calculated the number of Ions.
Atomic number is simply the number of protons in an atom. Each element has a unique atomic number (for example, hydrogen is always 1 and carbon is always 6).
Aluminum's atomic number is 13.
37.66 (g H2) / 2.016 (g/mol H2)= 18.68 mole H2Molar mass of hydrogen: 2.016 (g/mol H2)
You must count the number of woven pants produced. Obtain records of how many pieces were produced by all of the woven pants companies.
