Answer:
b=200
l=100
Explanation:
so since it is a square all sides would be equal
when you cut the square vertically the dimensions will change
the bredth would be same that is 200
but the length would be half that is 100
Answer:
Electrons are negatively charged particles that surround the atom's nucleus. Electrons were discovered by J. J. Thomson in 1897. *Protons are positively charged particles found within atomic nuclei.
Explanation:
The volume of concentrated HCl : 2.073 ml
<h3>Further explanation</h3>
Given
37% HCl by mass; density 1.19 g/mL
Required
The volume of concentrated HCl
Solution
Conversion to molarity :
37% x 1.19 g/ml =0.4403 g/ml
g/ml to mol/L :
=0.4403 g/ml x 1000 ml/L : 36.5 g/mol
=12.06 mol/L
or we can use formula :
Dilution formula :
M₁V₁=M₂V₂
12.06 M x V₁ = 0.1 M x 0.25 L
V₁ = 0.0021 L = 2.073 ml
The hot water increases the temperature of air in the bottle, which increases the volume of the bottle and the air pressure in the bottle.
Answer:
6 cucumberslices.
Explanation:
You can make a maximum of 4 sandwiches. 8 slices of tomato and 2 needed for each. 8/4=2. You need 4 slices of cucumber per sandwich and have 22. the maximum of sandwiches we can make is 4 so 4×4=16. 22-16=6 leftover slices of cucumber.
