Answer:

sir/ma'am, i know i'm a <u>NOOB</u> at this kind of stuff but i believe it's oxygen.

Explanation:

i can't really remember the answer since it's been a week or so that i done this problem, it's between nitrogen and oxygen, though, i believe it's oxygen.

if ya don't believe me or trust me, then here's the link to help ya:

Are bonds broken or formed, throughout each phase change present on a heating<br> curve?

Blababa [14]

Answer:

During a phase change no chemical bonds are broken. Atoms are not rearranged because a phase change is a physical change rather then a chemical change. However, intermolecular forces are almost entirely removed from the liquid since the intermolecular forces are what cause the liquid to be a liquid.

Explanation:the nature of the intermolecular forces (IMF) will not change when the state changes from solid to liquid, however, the number of IMF changes.

A sample of Ne gas has a pressure of 654 mmHg with an unknown volume. The gas has a pressure of 345 mmHg when the volume is 495m

Lemur [1.5K]

Answer:

The initial volume of Ne gas is 261mL

Explanation:

This question can be answered using Ideal Gas Equation;

However, the following are the given parameters

Initial Pressure = 654mmHg

Finial Pressure = 345mmHg

Final Volume = 495mL

Required

Initial Volume?

The question says that Temperature is constant;

This implies that, we'll make use of Boyle's law ideal gas equation which states;

$P_1V_1 = P_2V_2$

Where $P_1$ represent the initial pressure

$P_2$ represent the final pressure

$T_1$ represent the initial temperature

$T_2$ represent the final temperature

$P_1 = 654mmHg\\P_2 = 345mmHg\\V_2 = 495mL$

Substitute these values in the formula above;

$654 * V_1 = 345 * 495$

$654V_1 = 170775$

Divide both sides by 654

$\frac{654V_1}{654} = \frac{170775}{654}$

$V_1 = \frac{170775}{654}$

$V_1 = 261.123853211$

$V_1 = 261mL$ (Approximated)

<em>The initial volume of Ne gas is 261mL</em>

Answer:

From top to bottom coyote, crow, squirrel, then acorn

Explanation:

The coyote has the least amount of energy and its the biggest predator so it belongs at the top. The crows eat squirrels and the squirrels eat acorns.

Sulfur and fluorine form several different compounds including sulfur hexafluoride and sulfur tetrafluoride. Decomposition of a

svetoff [14.1K]

Answer:

See Explanation

Explanation:

For SF6;

Since;

1.25 g of S corresponds to 4.44g of F

1 g of sulphur corresponds to 1 * 4.44/1.25 = 3.55

For SF4;

Since;

1.88 g of S corresponds to 4.44g of F

1 g of sulphur corresponds to 1 * 4.44/ 1.88 = 2.36

Hence;

Mass of oxygen per gram of sulphur in SF6/Mass of oxygen per gram of sulphur in SF4

3.55/2.36 = 1.5

Hence the law of multiple proportion is obeyed here.
