GaF3+3Cs the product are 3CsF+Ga
Answer:
Mass = 253.4 g
Explanation:
Given data:
Mass of oxygen required = ?
Mass of hydrogen available = 32.0 g
Solution:
Chemical equation:
2H₂ + O₂ → 2H₂O
Number of moles of hydrogen:
Number of moles = mass/molar mass
Number of moles = 32.0 g/ 2.02 g/mol
Number of moles = 15.84 mol
Now we will compare the moles of hydrogen and oxygen:
H₂ : O₂
2 : 1
15.84 : 1/2×15.8 = 7.92 mol
Mass of oxygen required:
Mass = number of moles × molar mass
Mass = 7.92 mol × 32.00 g/mol
Mass = 253.4 g
The number of any one element is the coefficient times the subscript of that element. In BaSO₄, the coefficient is 1 and the subscript for oxygen is 4. In Ba(OH)₂, the coefficient is 1 and the subscript is 2. In Ba(OH)₂, the subscript is outside the because OH⁻ is an ion and the subscript applies to both elements
It called cation, Well, When an atom gains or loses an electron, it
attains a net charge and becomes an ion. When electrons are lost, the
resulting ion is called cation and when electrons are gained, the
resulting ion is called an anion. So, Cations have a net positive
charge, while anions have a net negative charge. it is true.
Two substances that are evenly mixed together. I hope this helped:)
