Answer:

63.25 grams of CO₂

Explanation:

To convert from liters to grams, we first need to convert from liters to moles. To do this, we divide the liters by 22.4, the amount of liters of a gas per mole.

32.2 / 22.4

= 1.4375 moles of CO₂

Now we want to convert from moles to grams. To do this, we multiply the moles by the molar mass of CO₂. The total molar mass can be found on the periodic table by adding up the molar mass of carbon (12) and two oxygen (32).

12 + 32 = 44

Now we want to multiply the moles by the molar mass.

1.4375 • 44

= 63.25 grams of CO₂

This is your answer.

Hope this helps!

Classify each of the following compounds as an acid, base, or both. Be sure to answer all parts

hichkok12 [17]

Explanation:

According to Bronsted-Lowry an acid is defined as the specie which is able to donate hydrogen ions when dissolved in water.

For example, $HCl \rightarrow H^{+} + Cl^{-}$

On the other hand, bases are the species which are able to donate hydroxide ions when dissolved in water.

For example, $NaOH \rightarrow Na^{+} + OH^{-}$

A specie which is able to accept a hydrogen atom and also able to donate a hydroxide ion will act as both acid and a base.

For example, $CH_{3}CH_{2}OH$ is able to donate a hydroxide ion and simultaneously can accept a hydrogen ion.

In $CH_3CH_2CH_2CH_3$ , the hydrogen atoms are strongly held together by the carbon atoms due to the small electronegativity difference between carbon and hydrogen atom. Hence, it will be a weak acid.

On the other hand, $CH_3CO_2CH_3$ can loose a hydrogen atom or it can also gain a hydroxyl group. This is due to the electronegativity difference between oxygen and hydrogen atom.

Thus, we can conclude that following compounds are classified as follows.

$CH_{3}CH_{2}OH$ - can be both acid and base

$CH_3CH_2CH_2CH_3$ - very weak acid

$CH_3CO_2CH_3$ - can be both acid and base

What is the percent mass of 55.0g NH4Cl dissolved in 137g water?

3241004551 [841]

Step 1

% by mass:

Mass of solute ---- 100 of solution

Mass of solution = mass of solute + mass of solvent = 55.0 g + 137 g = 192 g

Solute = NH4Cl

Solvent = Water (H2O)

-----------------------------

Step 2

Procedure:

55.0 g NH4Cl --------- 192 g solution

X ---------- 100 g solution

X = 29 g NH4Cl = 29 % by mass approx.

Answer: 29 % by mass

A pumpkin rolls 3.78 km in 6.8 hours. What is its speed?

Zielflug [23.3K]

Answer:

The answer is

Explanation:

The speed of an object given the distance and time can be found by using the formula

$speed = \frac{distance}{time} \\$

From the question

distance covered by pumpkin = 3.78 km

volume = 6.8 hours

The speed is

$speed = \frac{3.78}{6.80} \\ = 0.5558823...$

We have the final answer as

Hope this helps you

Nataliya [291]

Answer:

Explanation:

2 NO2(g) ⇄ N2O4(g)

Adding Argon to this reaction will have NO effect. Catalysts nor inert gases have an affect on equilibrium conditions.

Only changes in concentration, temperature conditions and pressure-volume conditions (unless both sides have equal molar volumes) will affect the equilibria.

NH4OH(aq) ⇄ NH3(g) + H2O(l)

Removing ammonia from reaction equilibrium causes the reaction to shift right to replace removed ammonia. => Think of the reaction as being on a seesaw => removing ammonia from the product side tilts the seesaw left causing the NH₄OH to decompose and deliver more NH₃ and H₂O to the product side to increase weight on that side and level the seesaw. :-)
