The answer is A because it is showing how they made an observation
Answer:
42g if CaO can be produced from 30g and 31.5g of CaO will be produced from 18g of O
Explanation:
40g of CA =56g
30g =×
cross multiple
=56*30/40
=42g
32g of O =56g
18g =×
cross multiple
=56*18/32
=31.5g
theoretical yield
42-31.5= 10.5
just guessing
D.) There must be an equal number of atoms of each element on both sides of the equation
B. Density
Density = mass/volume because it’s basically the concentration of mass. How much matter takes up the space. If you pack more matter into less space, it is more dense.
Fuse should only affect voltage
