A
Explanation:
It's a metal.
Metals in general go positive when the combine with a non metal. Li is going from 0 to 1 and that's A
Oil is hydrophobic, which means that it repels water. The ice cube will immediately begin to melt as soon as it is placed in the oil. Because oil is hydrophobic, it will not mix with the water.
If you leave the beaker overnight, you'll notice that the water sinks to the bottom and the oil floats to the top. This is because water has a higher density than oil, causing it to sink.
Hope this helps!
Answer:
Compound Interest is calculated on the initial Principal for a given unit of time(yearly, half-yearly, quarterly), it also includes all of the accumulated interests of the previous period of a loan or deposit.
In this type of interest, the amount after the first unit time becomes the principal for the second unit and the amount after second unit time becomes the principal for the third unit and so on.
So the difference between the final amount and the principal is called Compound interest.
If the interest is compounded yearly:-
A=P(1+R100)n
Here A = final Amount
P = Principal
R = interest rate
n = time period
Compound interest = Final amount - principal
Given:-
Principal (P) = $4000
Interest Rate (R) = 6%
Time period (n) = 5 years
Answer:
Heat, Q = 3035.073 J
Explanation:
It is given that,
Mass of water, m = 15.5 g
Initial temperature, 
Final temperature, 
The specific heat of water is, c = 4.184 J/ g°C
The heat removed or absorbed by water is given by formula as :
So, the heat of 3035.073 J is removed from 15.5 g of water.
