Answer:
i am not 100% shure but the wind speed has little to effect it so a and b are not the answer so i think the answer is D
Explanation:if i got this wrong im sorry it has bin a wile since i answered a question like this.
In one H₂O molecule, there are two hydrogen atoms along with one oxygen atom. So for every 1 oxygen atom (of which there are 2 of in an oxygen gas molecule) there needs to be 2 hydrogen atoms per oxygen( which in the equation of 2H2 +O2–> 2H2, that 2 H2 is broken down into 4 hydrogen atoms which means 2 hydrogen atoms have to bond to 1 oxygen atom and with 4 hydrogen atoms, there will be 2 atoms of oxygen which creates 2 molecules of water.
So to solve the question,
10.5g/2=5.25g of oxygen required to fully react with hydrogen to make water
They need other brands of cleaners to try it out with, and they need the same type of stain and same amount of stain on each same brand and same type of clothing.
The correct answer is D) Malleability
The weighted average atomic mass of Silicon is 28.1
(27.98 x .9223) + (28.98 x .0468) + (29.97 x .0309)
= 25.81 + 1.36 + .93
= 28.1
