Answer:
138 g of chlorine is required to produce 214 g of sodium chloride if we have 76 g of sodium.
Step-by-step explanation:
We are given:
Grams of Sodium = 76 g
Grams of Sodium Chloride = 214 g
We need to find how many grams of chlorine required to produce 214 g of sodium chloride
The equation will be:
We can write: 76 (g) + x (g)=214 (g)
Solving and finding value of x
x =214-76
x=138 g
So, 138 g of chlorine is required to produce 214 g of sodium chloride if we have 76 g of sodium.
Answer:
Step-by-step explanation:
3x - 6 + 2x + 108 + 88 = 360 Gather like terms
5x + 108 + 88 - 6 = 360
5x = 190 Divide by 5
x = 190/5
x = 38
Answer: 9
explanation:
4+(-7)= -3
next, you multiply -3 and -3 which is 9 as the two negatives cancel out
