Answer:
mass of ice is 1.75
Explanation:
Using, the formula given in the question,
m = Q/HΔf.................. Equation 1
Where Q = Heat, m = mass of ice, HΔf = Latent heat of fussion of for ice.
From the question,
Given: Q = 584.5 J, HΔf = 334 J/g
Substitute these values into equation 2
m = 584.5/334
m = 1.75 kg.
Hence the mass of ice without unit is 1.75
Answer:
After measuring the solute, Carl should first dissolve the solid in a small amount of DI water before diluting to the total volume.
Explanation:
To ensure that all the solute dissolves in the solution, first dissolve the solid in less than the total volume of solution needed.
Answer : The light rays are bent and refraction will occur - B.
The answer: Periods form horizontal rows, groups form vertical columns
Explanation:
The horizontal rows on the periodic table are called periods, while the verticals columns are called groups. Elements that are in the same group have similar properties. For example Group 1 is called the alkali metals. These are all soft, reactive metals.
