Answer:
Boiling point of solution is 
Explanation:
Cane sugar is a non-volatile solute.
According to Raoult's law for a non-volatile solute dissolved in a solution-
Where, 
is elivation in boiling point of solution, 
is ebbulioscopic constant of solvent (how much temperature is raised for dissolution of 1 mol of non-volatile solute) and m is molality of solution.
Here, 
610 g of cane sugar = 
moles of cane sugar
= 1.78 moles of cane sugar
So, molality of solution (m) = 
Plug in all the values in the above equation, we get-
So, boiling point of solution = 
Answer:
Physical properties increasing atomic number
Explanation:
The modern periodic table is arranged by the increasing atomic number and for that reason elements with similar chemical properties are in the same group
<h2>Which of the following reactions is endothermic-</h2><h2>½N2(g) + O2(g) + 8.1 kcal → NO2(g)</h2>
Explanation:
Chemical reaction
When two or more substances react and form some new substance it is called as chemical reaction .
A + B --> C + D
(reactants ) (products )
When ever chemical reaction occurs following changes can occur :
- Change in colour
- Ppt formation
- energy changes
- Change in state
- Evolution of gas etc
On the basis of energy changes : reactions are of two types :
Endothermic
Exothermic
Endothermic reaction
A reaction in which heat is absorbed .
Example :½N2(g) + O2(g) + 8.1 kcal → NO2(g)
Exothermic reaction
A reaction in which heat is released .
For example : H2(g) + ½O2(g) → H2O(g), ΔH = -57.82 kcal
½N2(g) + 3/2H2(g) → NH3(g) + 11.0 kcal
C(diamond) + O2(g) → CO2, ΔH = -94.50 kcal
Each Ba(OH)2 requires 2 Cl to produce one BaCl2 molecule.
<span>The 2 H's from the 2 HCl molecules combine with the 2 (OH) to form 2 H2O molecules. </span>
<span>2 HCl (aq) + Ba(OH)2 (s) ==> BaCl2 (aq) + 2 H2O (l)
I hope the answer will help you. </span>
D. Diffusion is a passive movement. Passive meaning it does not require energy, so ATP
