Sugar is the solute since it is the thing that is being dissolved.
And the water is the solvent since it is the thing that contains the solute.
Answer:
Explanation:
When adding or subtracting values, you must round your answer to the same "place" as the measurement with its last significant figure furthest to the left.
That is, you round off to the same number of decimal places as the measurement with the fewest decimal places.
The measurement of 28.1 cm has one digit after the decimal point, so you round the sum to have only one digit to the right of the decimal.
However, the number to be dropped (51) is greater than 5 with only zeros or nothing following the 5.
You must round up the answer. You increase the last significant digit by one.

Answer:
When the volume increased from 2.00 to 5.25L the new temperature is 808.9 K ( =535.75 °C)
Explanation:
Step 1: Data given
The initial volume of the sample = 2.00 L
The initial temperature = 35 °C = 308 K
The increased volume = 5.25 L
Pressure = constant
Step 2: Calculate the new temperature
V1/T1 = V2/T2
⇒ with V1 = the initial volume = 2.00 L
⇒ with T1 = the initial volume = 308 K
⇒ with V2 = the new volume = 5.25 L
⇒ with T2 = the new temperature
2.00 / 308 = 5.25 / T2
0.00649 = 5.25/T2
T2 = 5.25/ 0.00649
T2 = 808.9 K
When the volume increased from 2.00 to 5.25L the new temperature is 808.9 K ( =535.75 °C)
Answer:
The answer is B.
Explanation:
First of all, you can rule out options A and C because they are talking about covalent bonds. The cohesive property of water is given by intermolecular interactions, and covalent bonds are intramolecular (covalent bonds are the type of bonds that hold the atoms of a molecule together).
Now, you are left with options B and D. But option D is talking about bonds with different types of molecules, not with water. It is true that water can form hydrogen bonds with other molecules, but this property has nothing to do with its cohesivity. Cohesion is, by definition, the attraction of molecules of the same type. This leaves us with option B, which is talking about intermolecular interactions between water molecules, so this one is the only correct option.
