Answer : The boiling point of the resulting solution is, 
Explanation :
Formula used for Elevation in boiling point :
or,
where,
= boiling point of solution = ?
= boiling point of water = 
= boiling point constant = 
m = molality
i = Van't Hoff factor = 1 (for non-electrolyte)
= mass of solute (sucrose) = 5.0 g
= mass of solvent (water) = 10.0 g
= molar mass of solute (sucrose) = 342.3 g/mol
Now put all the given values in the above formula, we get:
Therefore, the boiling point of the resulting solution is,
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>
Sedimentary Rock because weathering and erosion breaks down the rock. Then, while the rock is being pressed and cemented, its forms sediments.
Answer:
Horizontal lines where the temperature is constant during phase changes connect upward-sloping lines where the temperature increases.
Step-by-step explanation:
The temperature is constant during a phase change (melting or boiling), so the graph is a horizontal line.
The temperature increases when a single phase (solid, liquid, or gas) is heated, so the graph for these changes has an upward slope.
A is <em>wrong</em>. A horizontal line shows a constant temperature.
B is <em>wrong</em>. There are no vertical lines in a heating curve.
D is <em>wrong.</em> A horizontal line does correspond to an increase in temperature.
