Answer:

-Gas collisions are elastic

- Gases mix faster than solids or liquids-

Gases with larger molecular weights diffuse slower than gases with lower molecular weights.

Explanation:

Matter is any substance that has weight and occupy space. There are three classes of matter. Theses are solid, liquid and gas.

Under Kinetic Theory of Gas

1. Gases move randomly in a straight line, thereby colliding with themselves and the walls of their containers

2. The collision of a gas molecule are perfectly elastic

3. temperature is a measure of average kinetic energy

Bearing this at the back of our minds, we can say that the following from the option applies to gases

-Gas collisions are elastic

- Gases mix faster than solids or liquids-

Gases with larger molecular weights diffuse slower than gases with lower molecular weights.

And these are not true

Gases with larger molecular weights diffuse faster than gases with lower molecular weights. Gas particles can move like solids and liquids along with translational motion.

Calculate the concentration (in mol/l) of 33% by weight (33 g naoh per 100 g of solution) naoh solution. (the density of the 33%
Shtirlitz [24]
Molarity is measured in moles per Liter. If there are 1.35 g/mL, find out how many grams there are in a liter of solution.

If there are 1000 mL in one liter, we can multiply by 1000 to get g/L

1.35 g/mL x 1 Liter/1000 mL = 1350 g per Liter of solution

By weight, the NaOH is 33% or .33

1350 g x .33 = 445.5 g of NaOH

Molar mass of NaOH is 39.997 g

445.5 g  x 1 mol NaOH/39.997 g = 11.13833538 moles per Liter

Rounded to significant figures, the answer is 11 mol/L NaOH

What indicators of a chemical reaction occurred in the following equation?
ch4aika [34]

Answer:

1) evolution of gas

2) evolution of heat

Explanation:

In this reaction, glucose is broken down into its constituents; carbon dioxide and water. The question is to decipher indicators of a chemical reaction from the equation.

If we look at the equation carefully, we will notice that a gas was evolved (CO2). The evolution of a gas indicates that a chemical reaction must have taken place. Secondly, energy is given off as heat. This is another indication that a chemical reaction has taken place.

Write the balanced electrochemical reaction for when zinc reacts with a copper solution. Label what is being oxidized and what i
Fed [463]

The balanced equation would be Zn + Cu^{2+} ---- > Cu + Zn^{2+}

<h3>Electrochemical equations</h3>

Zn reacts with Cu solution according to the following equation:

Zn + Cu^{2+} ---- > Cu + Zn^{2+}

In the reaction, Cu^{2+} is reduced according to the following: Cu^{2+} + 2 e^- -- > Cu

While Zn is oxidized according to the following: Zn - 2e^- --- > Zn^{2+}

Thus, giving the overall equation of; Zn + Cu^{2+} ---- > Cu + Zn^{2+}
