When salt is added to ice the temperature of the ice will even drop or the ice will melt
Answer:
The actual value of density will be less than the calculated value of density
Explanation:
Density is defined as mass per unit volume. This means that the value of the density of the substance depends on both its mass and its volume.
Since the volume of the water used in the experiment is greater than the required 100mL yet a volume of 100mL was used in the calculation, the actual density of the substance is less than the calculated value of density.
Nuclear binding energy is the energy that would be required to disassemble the nucleus of an atom into its component parts. These component parts are netrons and protons, which are collectively called nucleons
I think the answer is A. Hope that helped :)
1 mole ------------- 6.02 x 10²³ atoms
0.70 moles -------- ( atoms platinum )
atoms platinum = 0.70 x ( 6.02 x 10²³ ) / 1
= 4.2 x 10²³ atoms platinum
hope this helps!
