fires could cause a big difference in the weather of California
Glass 1 Freshwater
The egg went directly to the base of the glass. Consequently it has sunk and did not drift

A similar outcome for glass 2 as container 1 when egg was set into the container it sank to the base.

In reference to glass 1 and 2 the egg sank to the base for a third time.

Glass 4
Water with 4 teaspoons of salt
The egg remained gliding to where a little bit of the egg was standing out on the top, and when pushed down the egg returned up.

Number 4 is Global Warming
Answer: 
.
Explanation:
If percentage are given then we are taking total mass is 100 grams.
So, the mass of each element is equal to the percentage given.
Mass of K = 49.4 g
Mass of S = 20.3 g
Mass of O = 30.3 g
Step 1 : convert given masses into moles.
Moles of K=
Moles of S= \frac{\text{ given mass of S}}{\text{ molar mass of S}}= \frac{20.3g}{32g/mole}=0.63moles[/tex]
Moles of O = \frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{30.3g}{16g/mole}=1.89moles[/tex]
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For K = 
For S =
For O =
The ratio of K: S:O = 2: 1: 3
Hence the empirical formula is .
The answer
the general for of the equation of reaction is
N2 + 3 H2 ------------ 2NH3
1mol 3mole 2 mole
nH2 nNH3
(nX means number of mole of X)
according to the law of proportion
3 / nH2 = 2 / nNH3 (E)
nNH3 = m NH3 / 17.03 , and m NH3 = <span>0.575 g
consequently </span>nNH3 = 0.575 g / 17.03 = 0.03 mol
by considering (E) 3 / nH2 = 2 / 0.03 = 66.66, and nH2 = 3 / 66.66 =0.045
finally we can write
mH2 = nH2 x 2.0158 =0.045 x 2.0158 = 0.09 g
