Answer:
6.32 × 10⁻³
3.2560008× 10⁷
5.630× 10⁰
9.5002× 10¹
Explanation:
Scientific notation is the way to express the large value in short form.
The number in scientific notation have two parts.
The digits (decimal point will place after first digit)
× 10 ( the power which put the decimal point where it should be)
For example:
0.00632
In scientific notation = 6.32 × 10⁻³
32,560,008
In scientific notation = 3.2560008× 10⁷
5.630
In scientific notation = 5.630× 10⁰
95.002
In scientific notation = 9.5002× 10¹
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
Answer:
Explanation:
To find the number of moles of each element present in 1 mole of Be(OH)₂, we use the ratio of the molar masses of the elements to the compound and multiply by the given mole.
Molar mass of Be(OH)₂ = 9 + 2(16+1) = 43g/mol
number of moles of Be = 
x 1 = 0.209mole
number of moles of O = 
x 1 = 0.744mole
number of moles of H = 
x 1 = 0.047mole
