Answer: the amount of force on the spring scale
Explanation:
First solve the mass of 37.9 L seawater
M = 37.9 L ( 1000 ml / 1L ) ( 1.03 g / ml)
M = 39037 g
Then convert it to lb
M = 39037 g ( 1 lb / 453.592 g)
M = 86.06 lb
<span>Total weight = 86.06 lb + 59.5 lb = 145.56 lb so it can
support the aquarium</span>
<u>Answer:</u>
2400 mL
<u>Explanation:</u>
According to this equation, the stoichiometric ratio between and for the complete reaction is 1:2.
We know that the number of moles of can be calculated using the mole formula. (<em>number of moles = mass / molar mass</em>)
Moles of Calcium = = 1.5 mol
So the moles of = = 3.0 mol
<em>Volume of HCl solution = Moles of HCl/ concentration of HCl</em>
Volume of HCl solution = = 2400 mL
The number is 25. The square root of 25 is 5 and 5x2 is 10 and then 10+5 is 15
Answer: the correct answer is : too many fish caused an imbalance in the ecosystem, so the food web was affected.
