High tide is when the ocean rises
LAw of conservation of Energy is an important concept to solve this problem. The energy released is equal to the energy absorbed.
Ice undergoes latent heat. MEaning there is a change in phase but not temperature and the energy is solved by (enthalpy of fusion)(mass) = 333.5J/g)(8.5g). =2834.75J.
This is equal to the energy released by the water. The energy is computed by (mass)(specific heat of water)(temperature change) = (255g)(4.16J/gK)(T)
Final equation is:
2834.75 = 255(4.16)(T)
T = 2.67K
Answer:
13.1275%
Explanation:
Molecular formula of ethanol is C2H5OH
Molar mass of ethanol is 46.0684g/mol
Carbon: 24.02g/mol
Hydrogen: 6.05g/mol
Oxygen: 15.99g/mol
Mass percent of hydrogen = 6/46×100 = 13.1275%
Hope this helps, have a great day!
Answer:
1 mile = 1,609 meters
3.02E6 mi^2 x (1609^2m^2/mi^2) = 7.818E12 m^2
1 in= 2.54 cm => 2 in = 5.08cm = .0508m
7.818E12 m^2 x .0508m = 3.97E11 m^3
1 cubic meter = 1,000,000 cubic centimeters
3.97E11 m^3 x (1,000,000 cm^3 / m^3) = 3.97E17 cm^3
1000 cm^3 = 1L
3.97E17 cm^3 x (1L / 1000cm^3) = 3.97E14 L
or 3.97 x 10^14 L
convert to grams since 1L is 1000g
(3.97x10^14) x1000g which is 3.974x10^ 17g which is the final ans
Explanation:
In 52.6 mins the 10 mg of iodine will be divided by its half-life which is 2 it will become 5 mg (in 52.6 minutes ) and same procedure will be followed until it reach 99% out of the patient's system.
The answer is 368 minutes will it takes the iodine to be absorbed in one's system.
