1. The volume of a gas is 10.0 liters and its temperature is 1500 K. If the temperature is
cupoosta [38]

Answer:

5 L

Explanation:

So this problem refers to Charles's law. You would use this formula..

\frac{V_{I} }{T_{I} }  = \frac{V_{F} }{T_{F} }   (Initial volume / Initial Temperature) = (Final volume / Final Temperature)

For your problem, it would look like this...

\frac{10L}{1500k} = \frac{V_{F} }{750k}

You would cross multiply and your answer would be 5L.

To reassure yourself that the answer is correct, Charles law states that the Volume and the Temperature are directly proportional. Meaning if your temperature is decreasing, your volume <u>has</u> to decrease.

Please help . also need the name of their binary ionic compound . ​
madreJ [45]

Answer:

See below!

Explanation:

For the chemical formula, you need to have enough of each atom so that the charge is zero.

Aluminum has a +3 charge, and fluorine has a -1 charge.  Since the charge has to be zero, you need three fluorines, giving you AlF₃.

Barium has a +2 charge, and oxygen has a -2 charge.  Since the charges are equal in magnitude but opposite in sign, you only need one of each atom giving you BaO.

The name of the ionic compound will be the metal and then the nonmetal.  When putting the nonmetal in, change the ending to "-ide".  For example "chlorine" would be "chloride.

CaCl₂  ==>  calcium chloride

Ga₂S₃  ==>  gallium sulfide

K₃N  ==>  potassium nitride

AlF₃ ==>  aluminum fluoride

BaO  ==>  barium oxide
