A) Mass Number B) Protons and Electrons C) (I think group but I'm not 100% sure on this...) D) 12 (To work out the number of neutrons you do MASS number - ATOMIC number aka the number of protons so in this case you'd do 23-11=12) Hope this helps

What would you need to do to calculate the molality of 10 g of NaCl in 2 kg of
jasenka [17]

Answer:

O B. Convert the 10 g of NaCl to moles of NaCl.

Explanation:

The formula for finding the molality is m=moles of solute/kg of solvent. The solute for this question is NaCl and the solvent is water.

(10g NaCl)(1 mol NaCl/58.44g NaCl)=0.1711 mol NaCl

58.44 is the molar mass of NaCl

m=0.1711 mol NaCl/2 kg H2O

m=0.085557837

A phase change for carbon dioxide that occurs spontaneously at 20.°C and 1.0 atmosphere is represented by the balanced equation
Troyanec [42]

Answer:

The name of the phase change is;

Sublimation.

Explanation:

CO₂(s) + energy ⇒ CO₂(g)

Sublimation is the transition of a substance from its solid state to the gaseous state without first turning to a liquid due the high rate of absorption of of thermal energy of the substance such that the substance does not melt first.

As such sublimation is the endothermic process taking place at  a temperature and pressure lower than the triple point of the substance in the substance's phase diagram. The triple point is the lowest temperature and pressure at which a substance can exist as a liquid.
