Answer:
P₄ + 5O₂ → 2P₂O₅
Explanation:
Phosphorus burn in the presence of air and produced diphosphorus pentoxide.
Chemical equation:
P₄ + O₂ → P₂O₅
Balanced chemical equation:
P₄ + 5O₂ → 2P₂O₅
Equation is balanced because there are four phosphorus atoms ans ten oxygen atoms in both side of equation.
Coefficient with reactant and product:
P₄ 1
O₂ 5
P₂O₅ 2
About 7.1 litres all you have to do is to divide divide the volume value by 1000
The right answer is
Table A Organic solvent
No Perfume No Fuel No Anesthetic No Adhesive Yes
Answer:
25.5 g
Explanation:
First, you will need a balanced chemical equation
CuO + H₂ ==> H₂O + Cu
From the equation above, we can see that for every 1 mole of CuO (copper(II) oxide), 1 mole of Cu (copper) is produced.
Convert grams of CuO to moles. You should get 0.402 mol. Now with the relationship established above, you can see that you should ideally get 0.402 mol. Convert this to grams. Your answer should be 25.5 g.
dissolves easily in water
has a high boiling point
has a high melting point
conducts electricity when melted
Explanation:
Salts are ionic compounds. Ionic compounds are formed when two atoms exchange their valence electrons. One atom gains and the other atom loses.
Generally, ionic compounds have the following properties:
- They are usually hard solids with high melting points or liquids with high boiling points.
- They are soluble in water and insoluble in non-polar solvents. This is conforms with the solubility rule that like dissolve like.
- In aqueous solution or molten form, ionic compounds conducts electricity.
- They take part in very fast chemical reactions.
