Answer:
no dont worry its in decimal point
anything after the point is considered as not to the fullest
Answer:
7.5 mol
Step-by-step explanation:
2Al + 3Br₂ ⟶ 2AlBr₃
You want to convert moles of AlBr₃ to moles of Br₂.
The molar ratio is 3 mol Br₂:2 mol AlBr₃.
Moles of Br₂ = 5 × 3/2
Moles of Br₂ = 7.5 mol Br₂
You need 7.5 mol of Br₂ to produce 5 mol of AlBr₃.
It has 4 pcs of Carbon (C) and 8 pcs of Hydrogen (H) so the formula is C4H8 - calls Butene.
Hope it helps!

Mass =70 ( Mass of protons=1 ,Mass of neutrons =1, Mass of electron =0.0005(can be ignored))
Therefore, 40 +30=70
Charge= -2 ( it is taking in/attracting electrons to its shell) base on the proton number you are able to identify if it is attracting or releasing an electron, if the electron number is more than proton number then it is attracting therefore resulting in a negative charge vice versa for releasing an electron.
Answer:
36 atoms
Explanation:
- C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy
The reactants are in the left side of the equation. <u>First we determine how many atoms are there in the C₆H₁₂O₆ molecule</u>:
- 6 C atoms + 12 H atoms + 6 O atoms = 24 atoms in total
There are two atoms in a O₂ molecule, and there are 6 O₂ molecules in the equation:
- 2 * (6 O atoms) = 12 atoms in total
The total number of atoms in the reactants is
