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

6 (3) - 4 + 32

hope this

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
