Astudent needs to use 0.575 moles of sodium chloride in an experiment. how many grams should he mass out?

33.6 g

Step-by-step explanation:

Step 1. Calculate the molar mass of NaCl

Na      = 22.99

Cl       = 35.45

Total = 58.44 g/mol

Step 2. Calculate the mass of NaCl

Mass of CO₂ = 0.575 mol NaCl × (58.44 g NaCl/1 mol NaCl₂)

Mass of CO₂ = 33.6 g CO₂

neutrons are in the middle of the atom and the electrons, which are much smaller.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
