By gaining an electron (perhaps via beta particle). The H+ ion needs another electron to remove its positive charge.
I believe the answers would be...
1. Vegetative
2. True
The electrolysis of water will yield hydrogen gas and oxygen gas as the final products. Oxygen gas and hydrogen ions are formed when the water reacts at the anode. The hydrogen ions then move to the cathode where hydrogen gas is formed.
61.8 % is the mass percentage of magnesium sulphate.
Explanation:
The mass percent of individual solute or ion in a compound is calculated by the formula:
Grams of solute ÷ grams of solute + solvent × 100
mass percent of magnesium is calculated as 1 mole of magnesium having 24.305 grams/mole will have weight of 24.305 grams and 1 mole of MgSO4 will have 120.366 grams
Putting the values in the equation:
24.305 ÷ 144.671 × 100
= 16.8% of magnesium is in the mixture
The mass percentage of SO4 is calculated as
= 96.06 ÷ 216.426 × 100
= 44.38 %
The mass percentage of the mixture MgSO4 is 44.38 + 16.8 = 61.8 %
Mass percentage is a representation of the concentration of element or elements in a compound.
Answer:
electron transfer to occur to form ions.
