Answer: doing it right now
Explanation:
the picture
Because the intention is to boil the solution, the purpose of the solvent is to dissolve so it has a higher boiling point so ensure it stays in liquid form and doesn't evaporate into a gas
also, a pure solvent is made of 1 substance so it has 1 boiling point and the solution must evaporate/boil first
I’m pretty sure it’s D because energy measures the kinetic, thermal, electrical, chemical, nuclear and other forms.
Answer:
Therefore the theoretical density of iron is 7.877 g/cm³ .
Therefore the number of vacancy per cm³ is
Explanation:
Explanation:
no. of molea of Ca(NO3)2 = given mass/molar mass
no. of moles= 92/ 164 = 0.56 mol
formula=
Molarity = moles of solute /solution in litres
Molarity = 0.56/ 0.4
=1.4 M
hope it helped!
