Chemical reaction is given as :
Here, 2 moles of water gives 2 moles of hydrogen and one mole of oxygen.
Mass of hydrogen = 28.0 g (given)
Mass of oxygen = 224.0 g (given)
Number of moles = 
Thus, number of moles of hydrogen = 
= 14 moles of hydrogen
Number of moles of oxygen= 
= 7 moles of oxygen
Now, to find the amount of water:
= 252 g of water.
Thus, amount of water is 252 g (involved in the process).
Answer:
The answer is: 18 moles and 1341, 72 grams of KCl
Explanation:
The molarity is defined as the moles of solute ( in this case KCl) in 1 liter of solution:
1L solution-----3 moles of KCl
6L solution-----x= (6L solutionx 3 moles of KCl)/1 L solution= <em>18 moles of KCl</em>
<em></em>
We calculate the weight of 1 mol of KCl:
Weight 1 mol KCl= Weight K + Weight Cl= 39,09 g + 35, 45 g=74, 54 g/mol
1 mol KCl----- 74, 54 g
18 mol KCl----x= (18 mol KCl x 74, 54 g)/1 mol KCl=<em>1341, 72 g</em>
Answer: The proteins were no longer soluble in the blood.
Answer:
6960 J/kg°C
Explanation:
specific heat= mass×specific heat capacity×increase in temperature
specific heat= 0.240×1450×20= 6960 J/kg°C
