Answer:
the moon is the earths natural satellite.
Explanation:
A natural satellite is in the most common usage, an astronomical body that orbits a planet, dwarf planet, or small Solar System body (or sometimes another natural satellite). Natural satellites are often colloquially referred to as moons, a derivation from the Moon of Earth.
First step: convert 22.4% into fraction
that is 22.4/100 which is equivalent to 0.224
The mass of Cucl2 contained in 75.85 of 22.4% by mass of solution of CUcl2 in water is therefore,
0.224 x75.85=16.99g
alternatively
75.85 --->100%
? 22.4%
by cross multiplication =(22.4 x 75.85)/100 =16.99g
Answer: molarity = mole solute/ liter of solution.
=> volume= mole/molarity = 1/5 = 0.2 L = 200mL
Explanation:
I believe your answer is true! Hope this helps!
The reaction equation is already balanced. So the mole ration of reactants and production is the ratio of the coefficients. So the mole ratio of N2 to NO2 is 1:2.
