10g of Copper reacts with 5g of Sulfur How much Sulfur is needed to react with 20g of Copper?

10g of Sulfur reacted with 20g of Cu

Step-by-step explanation:

10g of Cu = 5g of Sulfur

20g of Cu = x Sulfur

You can cross multiply or just flip the grams on the left to

20g ÷ 10g × 5

=20/10 = 2

2× 5 = 10g

d. corresponding side lengths in similar triangles are proportional in length.

step-by-step explanation:

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
