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

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
