Answer:
The answer is a compound.
it is a compound as it contains different elements
Explanation:
Answer:
15.89%
Explanation:
To calculate the percentage of carbon in BeC2O4•3H2O, first we calculate the molar mass of BeC2O4•3H2O
MM of BeC2O4•3H2O = 9+(12x2)+(4x16)+3(2+16) = 9+24+64+54 =151g/mol
Mass of C in BeC2O4•3H2O = 2x12 = 24g
%Mass of carbon in BeC2O4•3H2O = (24/151) x 100
= 15.89%
Answer:
As the larger quantity
As the liquid which dissolves a solid
Explanation:
Solvent is the substance mostly in liquid form which dissolves the solute(e.g solid). The solvent also, is larger when compared to the solute.
Answer:
letter A.
Explanation:
the rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. this is done by cutting the substance into small pieces, or by grinding it into a powder.if the surface area of a reactant is inceased: more particles are exposed to the other reactant.
