Answer:

Exothermic.

Explanation:

Exothermic is when he leaves the system. A way to remember is the "ex" which is a prefix/root/suffix or something that pretty much means leaving, I think. For example how it's in "Exodus" and "Exit", I think.

Endothermic is when it goes into the system. Similar to "ex" but with inside, I think. For example how it's in "Endoskeleton", I suppose.

A container holds 500 mL of oxygen gas at a pressure of 1.3 atm and a temperature of 25 ˚C. If the temperature increases to 29 ˚
Ksivusya [100]

Answer:

The new volume of the gas is decreased, to 0.329 L

Explanation:

Step 1: Data given

Volume of oxygen = 500 mL = 0.500 L

Pressure = 1.3 atm

Temperature = 25.0 °C

Temperature increases to 29.0 °C

New pressure = 2.0 atm

Step 2: Calculate new volume

p1*V1/T1 = p2*V2/T2

⇒with p1 = the initial pressure = 1.3 atm

⇒with V1 = the initial volume = 0.500L

⇒with T1 = the initial temperature = 25 °C = 298 K

⇒with p2 = the new pressure = 2.0 atm

⇒with V2 = the new volume = TO BE DETERMINED

⇒with T2 = the new temperature = 29 °C = 302 K

(1.3 * 0.500)/298 = (2.0 * V2) /302

0.0021812 = 2.0V2 / 302

V2 = 0.329 L = 329 mL

The new volume of the gas is decreased, to 0.329 L

Why does the nucleus of an atom have a positive charge but overall have a neutral<br> charge?
Mashutka [201]

Answer:

The nucleus has an overall positive charge as it contains the protons. Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.
