Answer:
Explanation:
The mass percentages of chlorine and fluorine:
Given:
Mass of chlorine = 5.753g
Mass of fluorine = 9.248g
Find the total of the masses given:
Total mass = mass of chlorine + mass of fluorine = 5.753 + 9.248 = 15.001g
% of Cl = 
x 100
% of Cl = 
x 100 = 38.35%
% of F = 
x 100
% of F = 
x 100 = 61.65%
The french broad? idk sorry

- <em>A skeleton equation shows just the reactants and products whereas a balanced equation shows the</em><u> relative amounts of, or proportion between, reactants and products.</u>
Explanation:
The <em>skeleton equation</em> shows which <em>reactants </em>are being used and which <em>products </em>are being formed.
The reactants are shown on the left and the products are shown on the right side of the equations, separeted by an arrow.
For example, the skeleton equation to obtain water is:
From it you know that hydrogen and oxygen react to form water, yet you do not know in which ratio they do it.
Then, you balance the equation, adding the appropiate coefficients, to make the number of atoms of each kind on the reactant side equal to the number of the same kind of atoms on the product side.
This is, for the example of water, the number of hydrogen atoms on the left must equal the number of atoms of hygrogen on the right side, and the number of oxygen atoms of the left must equal the number of oxygen atoms on the right.
For the water example that is:
- 2H₂(g) + O₂(g) → 2H₂O (g)
- Showing that 2 molecuies of hydrogen (or 4 atoms) react with 1 molecule of oxygen (or 2 atoms) to produce 2 molecules of water, and that proportion (relative amounts) will always be true for that reaction.
Atmospheric pressure is measured using a barometer.the pressure isnt the same everywhere on earth but it would depend on the height of the location
Answer:
D. Thermal conduction is blocked by the flip-flops.
Explanation:
Convection is a process of heat transfer which involves fluids( liquid or gas). This however rules convection out of the answer.
Radiation involves heat transfer from the sun to bodies on earth.
Conduction involves heat transfer between two solid bodies. Hot beach sand and flip-flops are solid bodies which validates thermal(heat) conduction.
