Answer:
12.5 gm left
Explanation:
30 minutes is THREE half lives
1/2^3 = 1/8th would be left
100g * 1/8 = 12.5 gm
Answer:
They contain atoms that combine together to form molecules. In multicellular organisms, such as animals, molecules can interact to form cells that combine to form tissues, which make up organs. ... All atoms contain protons, electrons, and neutrons.
Answer:
Find the steps and explanation below.
Explanation:
A. Kids make slime following these basic steps;
1. In a bowl, is 1/4 cup of water is added to 1 oz. of glue. Add coloring if you wish to.
2. 1/4 cup of Borax solution, also known as Sodium Tetraborate is added to the mixture and gradually stirred.
3. The mixture is kneaded with the hands to ensure a smooth consistency.
4. Water remnants are discarded and the slime is stored in a plastic bag and kept in the fridge.
B.
What each ingredient does
Polyvinyl acetate present in the glue acts as a liquid polymer.
Borax binds the liquid polymers together.
Water eases the mixing process
C.
If lesser ingredients are used, the slime will not have its characteristic slimy nature. If excess of the ingredients are used, the slime becomes very sticky.
Answer:
H-F> H-O> O-F
while H-H is nonpolar.
Explanation:
The bond is polar when electronegativity difference of both bonded atom is greater than 0.4.
Electronegativity values of O. F and H are
O = 3.4
H = 2.2
F = 3.98
For O-F
3.98 - 3.4 = 0.58
For H-F
3.98 - 2.2 = 1.78
For H-O
3.4 - 2.2 = 1.2
For H-H
2.2 -2.2 = 0
So H-H is nonpolar.
