Answer:
The volume of cupboard is 2.0043 m³.
Explanation:
Given data:
width of cupboard = 1.31 m
length of cupboard = 0.9 m
height of cupboard = 1.70 m
Volume = ?
Solution:
Volume = length × width × height
Volume = 0.9 m × 1.31 m × 1.70 m
Volume = 2.0043 m³
The volume of cupboard is 2.0043 m³.
that is false it shows you the atoms but the arrangement would have to be a Lewis dot diagram
Answer:
Ca3(PO4)2- Increase in solubility
Barium hydroxide- increase in solubility
Magnesium carbonate- increase in solubility
Copper II sulphide- increase solubility
Lead II bromide- increase solubility
CuI - increase solubility
Explanation:
Calcium phosphate solubility is pH dependent. At lower pH, calcium phosphate is more soluble in water while at pH above 8.5, the solubility of calcium phosphate decreases markedly.
For Barium hydroxide and magnesium carbonate,decreasing the pH will increase the solubility of the compound.
For copper II sulphide,decreasing the pH will lead to a greater solubility. Also, lead II bromide is ordinarily insoluble in water but it's solubility increases with decreasing pH.
CuI is insoluble in water but soluble in dilute hydrochloric acid.
The answer would be C. because if you burn coal can you get the same piece of coal back?
