So it's good to map out what you know you have and work from there:
We have two liter measurements and one mole measurement, and we need to find the moles.
For this problem, think of it this way: 46 liters of gas = 1.4 moles.
If one side changes, the other has to as well (if the liters decrease, the moles decrease. if the liters increase, so do the moles.) What you can do is put this into a fraction:
<span><u>1.4 moles</u></span>
46 L <span> </span>
if we know that each liter of gas is equal to x amount of moles, we know that 11.5 liters equals some amount of moles. You can put this into a fraction too, and make it equal to the other fraction:
<span><u>1.4 moles</u></span> = <u>x moles</u>
46 L 11.5 L
Then get your calculator out and do some algebra.
11.5 * (1.4/46) = x
The answer should come out to be: 0.35 moles
Answer:
Explanation:
halogen group
Electron affinities are negative numbers because energy is released. The elements of the halogen group (Group 17) gain electrons most readily, as can be seen from their large negative electron affinitie
Answer:
Im pretty sure its 2 How elements are joined in the compound
Explanation:
As, the chemicals are toxic, they have adverse effects in our life.
<h3>What is chemical?</h3>
A compound or element which reacts with the other element to form a product.
Chemicals are generally toxic because they harm our skin, when they come in contact with the body. When exposed to a toxic substance, gasoline can affect your health. Since, drinking gasoline can cause burns, vomiting, diarrhea and can cause death,
Thus, the chemicals are toxic.
