The ratio of hydrogen to oxygen atoms in water molecules is 2 to 1. If the beaker of water contained 4.1 moles of oxygen atoms,

Ad libitum [116K]

Answer:

8.2

Step-by-step explanation:

We have been given that the ratio of hydrogen to oxygen atoms in water molecules is 2 to 1.

We can represent this information as: $\frac{\text{Hydrogen}}{\text{Oxygen}} =\frac{2}{1}$

Let x be amount of moles of hydrogen atoms in water beaker. The proportion of hydrogen and oxygen moles will be same in water beaker.

Upon substituting our values in above proportion we will get,

$\frac{2}{1} =\frac{x}{4.1}$

$x=2\times 4.1$

$x=8.2$

Therefore, the moles of hydrogen atoms in water beaker will be 8.2.

Naddik [55]

You would combine like this:

Then divide off the sides
17e/17e 18/17e which cross out the 17 e which leaves you with 1.1

When h=0, T is the highest (because the temperature is highest at noon)

And knowing that the temperature difference in the world cannot exceed 60 degrees in a day, only the first choice is common sense.
