A. Be2Cl.

B. 2BeCl.

C. BeCl2.

D. Be2Cl2.

Answer 1

THink of water

h 2 o

2 h per 1 o

Answer 2

im confused how do i think of water? what represents the water

Answer 3

YOu heard of H20

that is because there are 2 H and 1 O

a 2 to 1 ratio

if someone says 2 Be and one Cl

then...?

Answer 4

then it would be 2be and one cl right?

Answer 5

yes :D

Answer 6

but remember

Answer 7

H2O

X2Y

it means 2 x 1 y

therefore

Be2Cl.

Answer 8

thanks alot ;)

Answer 9

Wow. Be careful.

Water has a two-to-one ratio of hydrogen to oxygen. Beryllium chloride has a one-to-two beryllium to chloride ratio.

Take a look at the periodic table. Beryllium has a charge of +2. Chlorine has a charge of -1. We need TWO chlorine ions to balance the charge.

Answer 10

then there for it would be Be2Cl2?

Answer 11

crap should have re read

Answer 12

one-to-two apple to orange ratio would be 1 apple, 2 oranges.

one-to-two beryllium to chlorine ratio would be 1 beryllium, 2 chlorines.

Answer 13

one-to-two ratio of beryllium ions to chloride ions

Answer 14

1 Be
2 cl

Answer 15

Sorry about that.

I was gonna check on the table :P

Answer 16

but I thought I read it right the first time

Answer 17
