The correct answer is B. A homogeneous mixture has the same properties for every part of the mixture, so the quality of the material is consistent.
Explanation:
In a homogenous mixture, all the components are equally integrated; this means the final result in the case of a material is a material that looks uniform and also has the same properties in every part of section. This homogeneity and consistency are especially important if you are testing the properties of the material or using it for a specific application because if you use a homogenous mixture the quality and properties will be consistent and thus you can obtain consistent results.
Answer: c) No, using 175 g of sodium chloride in 5 L of solution will give a 3.5% solution.
Explanation:
Percent of solution = 35 %
Mass of solute = 175 g
Volume of solution = 5L = 5000 ml (1L=1000ml)
Mass by volume percent (m/v)% : It is defined as the mass of solute present in 100 ml of solution.
Formula used :
Now put all the given values in this formula:
Thus the mass by volume percent is 3.5 % and not 35%.
Answer:
For chemical reactions involving gases, gas volume measurements provide a convenient means of determining stoichiometric relationships.

The nuclear symbol of the isotopes of gallium where as the symbol must be determined according to its parts and they are the symbol of the element, the atomic number of the element and also the mass number of the specific isotopes. So the symbols is Ga 42 over 71 . I hope this would help
