Answer:
0.427 g HClO4
Explanation:
[H+]= 10^-3.3 = 5.01 x 10^-4 M
8500 mL=8.5 L
M= mol solute/ L solution
mol solute= M* L solution
mol solute= (5.01 x 10^-4 M * 8.5 L)
mol solute= 4.26 x 10^3 mol HClO4
1 mol HClO4 -> 100. 4 g
4.26 x 10^3 mol HClO4 -> x
x=0.427 g HClO4
To separate a mixture of rocks and sand I think water will be the best option to break it down
It is because water is a liquid form.
Answer: 
Explanation:
To calculate the initial temperature of the water:
where,
q = heat absorbed = 
= specific heat of water = 
m = mass of water = 2230 g
= final temperature of water = 
= initial temperature of metal = ?
Now put all the given values in the above formula, we get:
Thus, the initial temperature of the water is
