The answer is false..............<span>kinetic theory of gases is a topic that can explain many everyday observations. Have you ever wondered why water boils faster at higher altitudes? Or why inflatable pool toys seem flat after sitting in a cold garage? How about why you can smell a candle all throughout the house? All of these phenomena and many more can be explained by the kinetic theory of gases.</span>

Given a fixed amount of gas held at constant pressure, calculate the volume (in L) it would occupy if a 3.50 L sample were coole
Over [174]

Answer:

V₂ = 2.91 L

Explanation:

Given data:

Initial volume = 3.50 L

Initial temperature = 90.0°C (90+273 = 363 K)

Final temperature = 30.0 °C  ( 30 +273 = 303 K)

Final volume = ?

Solution:

V₁ = Initial volume

T₁  =  Initial temperature

V₂ = Final volume

T₂ = Final temperature

V₁/T₁  =  V₂/T₂

3.50 L / 363 K) =  V₂ / 303 K)

V₂ = 0.0096 L/K × 303 K

V₂ = 2.91 L

Match the name of each gas law to the properties it compares. 1. Gay-Lussac's law 2. Boyle's law 3. Avogadro's law a. Volume and
oee [108]

Answer:

1. C    2. B     3.  A

Explanation:

1. Gay- Lussac law, states that as along as the volume is kept constant, the      pressure of a fixed mass of gas is directly proportional to the temperature.

The properties it compares is; (c.) Pressure and temperature

2.  Boyle's Law states that; as long as the temperature is kept constant, the volume of a fixed mass of gas is inversely proportional to the pressure.

It therefore compares; (b.) Pressure and volume

3. Avogadro's Law states that equal volumes of different gases contain the same number of molecules provided the temperature and pressure are the same.

It therefore compares;  (a.) Volume and moles

Write a balanced chemical equation for the standard formation reaction of solid chromium(iii) nitrate crno33 .
Drupady [299]

Explanation:

Standard formation of an substance is defined as formation of one mole of substance from its constituting elements.

Chromium(III) nitrate is composed of chromium, nitrogen and three oxygen atoms.

2Cr(s)+3N_2(g)+9O_2\rightarrow 2Cr(NO_3)_3(s)

A balanced chemical equation for the standard formation reaction of solid chromium(III) nitrate

Cr(s)+\frac{3}{2}N_2(g)+\frac{9}{2}O_2\rightarrow Cr(NO_3)_3(s)

Identify the type of reaction and then balance the equation for each of the following reactions.
alexgriva [62]

Answer:

The answer to your question is below

Explanation:

There are 4 types of chemical reactions:

- Synthesis is when two elements or compounds form only one compound.

- Decomposition is when 1 compound is broken into 2 or more products.

- Single replacement is when one element is replaced by another element.

- Double replacement is when the cations of two compounds are interchanged.

1.- Decomposition                      2 Al₂O₃    ⇒    4 Al   +  3O₂

2.- Single replacement          Mg  +  2HNO₃   ⇒   Mg(NO₃)₂   +  H₂

3.- Combustion                      2C₆H₆  +  15O₂   ⇒   12CO₂   +   6H₂O

4.- Synthesis                          2Ag   +   S   ⇒   Ag₂S

5.- Double replacement      3Ca(OH)₂   + 2H₃PO₄   ⇒   Ca₃(PO₄)₂  + 6 H₂O
