When applying monomer liquid and polymer powder nail enhancements, after dipping the brush in monomer liquid and removing the excess, you should:

Dip the same brush into the polymer powder and slightly rotate it

Explanation:

After removing the excess, dipping the same brush into the polymer powder and rotating it slightly would form a paste solution that can be used for enhancement, e.g nail enhancement called sculptured nails.

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.

e

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
