The heat needed to raise the temperature of 50g of substance by 15 c is calculated as follows
Heat = mc delta T
m= mass (50g)
c= specific heat capacity (0.92)
delta T= change in temperature( 15 c)
heat is therefore= 50 x 0.92 x 15 = 690
Nb: my answer has no units since the given specific heat capacity has no units
Answer:
by measuring the circumference, diameter, and radius of both volleyballs.
the process of changing one form of energy into another
To find out the molar mass, you have to break down each of the elements, then add them up.
C6 = 12.01 x 6 = 72.06 (Beacause, there are 6 carbon atoms)
H12 = 1.01 x 12 = 12.12 (Because, there are 12 hydrogen atoms)
O6 = 16.00 x 6 = 96 (Because there are 6 oxygen atoms)
Now, you will add all three of the elements up: 72.06 + 12.12 + 96 = 180.18.
So the molar mass of glucose is 180.18.
Answer: D. sugar dissolves when placed in water.
Why:
Chemical properties/changes produce NEW substances.
So when sugar dissolves in water, it breaks down, but NOT to a chemical level that separates its elements. Therefore, it would still be sugar and will not create a new compound/element.
This results in the conclusion that when sugar dissolves in water, it is a physical property, NOT chemical.
