Atanker truck carrying 6.05×103 kg of concentrated sulfuric acid solution tips over and spills its load. the sulfuric acid solution is 95.0%h2so4 by mass and has a density of 1.84 g/ml.

part a

sodium carbonate (na2co3) is used to neutralize the sulfuric acid spill. how many kilograms of sodium carbonate must be added to neutralize 6.05×103 kg of sulfuric acid solution?

express your answer with the appropriate units

6,216.684 kilograms of sodium carbonate must be added to neutralize of sulfuric acid solution.

Explanation:

Mass of sulfuric acid solution =

Percentage mass of sulfuric acid = 95.0%

Mass of sulfuric acid =

Moles of sulfuric acid =

According to reaction , 1 mole of sulfuric acid is neutralized by 1 mole of sodium carbonate.

Then 58,647.96 moles of sulfuric acisd will be neutralized by :

of sodium carbonate

Mass of 58,647.96 moles of sodium carbonate :

6,216,683.76 g = 6,216,683.76 × 0.001 kg = 6,216.684 kg

6,216.684 kilograms of sodium carbonate must be added to neutralize of sulfuric acid solution.

linda: 3 ; laura: 15

step-by-step explanation:

note that linda + laura's age is 18, and that linda is 12 years younger than her sister.

let "linda" = x , "laura" = y:

x + y = 18

x = y - 12

first, plug in y - 12 for x in the first equation:

(y - 12) + y = 18

simplify.

2y - 12 = 18

isolate the variable (y). note the equal sign, what you do to one side, you do to the other. do the opposite of pemdas. first add, then divide.

2y - 12 (+12) = 18 (+12)

2y = 18 + 12

2y = 30

(2y)/2 = (30)/2

y = 30/2

y = 15

next, plug in 15 for y in the second equation (the other equation would work too).

x = y - 12

x = (15) - 12

x = 3

linda's age is 3, laura's age is 15.
