Imagine that you combine lemon juice with baking soda in a glass. You see gas bubbles forming along the sides of the glass. How

are the chemical properties of the gas different from the chemical properties of the baking soda and lemon juice?

<span>The gas that is formed is a different state of matter from the baking soda and lemon juice. The lemon juice has a different odor or smell than the gas. There is no color in the gas, while the lemon juice is yellow, and the baking soda is white.

Answer:

Gas released in this process is a totally different chemical substance in comparison to the baking soda and lemon juice. It should be Carbon Dioxide formed during the reaction.

Explanation:

We have a baking soda in a glass: it is composed of water and baking soda (NaHCO3). We have lemon juice, its main component is the citric acid (H3C6H5O7). After that, both liquids are mixed and an acid-base reaction occurs.

The reaction releases gas, which should be carbon dioxide (CO2), according to this reaction:

H3C6H5O7 (aq) + 3 NaHCO3 (aq) → 3 CO2 (g) +3H2O (l) + Na3C6H5O7 (aq)

The products of this reaction are Water (H2O) a Salt and carbon dioxide. As carbon dioxide is in the gas phase, it will be released from the liquid mixture as bubbles.

Finally, we can conclude that Gas released in this process is a totally different chemical substance in comparison to the baking soda and lemon juice. It should be Carbon Dioxide formed during the reaction.

If a zero order reaction has a rate constant k of 0.0416Mmin and an initial concentration of 2.29 M, what will be its concentrat
babymother [125]

Answer:

The concentration after 20 mins is 0.832 M

Explanation:

Zero order rate law is given by;

R = K [A₀]⁰

A zero order reaction, rate is independent of the initial concentration

R = K

Where;

R is the rate of reaction

K is the rate constant = 0.0416 M/min

Since R = K,

Then, R = 0.0416 M/min

After 20 min, the concentration will be;

A = Rt

A = (0.0416 M/min)(20 min)

A = 0.832 M

Therefore, the concentration after 20 mins is 0.832 M

A) How many moles of CO2 and H2O are formed from 3.85 mole of propane C3H8 (This calculation needs to be done twice-once fro CO2
4vir4ik [10]

Answer:

a) 11.55 moles of carbon dioxide gas are formed from 3.85 mole of propane.

15.4 moles of water are formed from 3.85 mole of propane.

b)0.5176 moles of water are formed from 0.647 mole of oxygen gas.

0.1294 moles of propane are consumed.

Explanation:

C_3H_7+5O_2\rightarrow 3CO_2+4H_2O

a) Moles of propane = 3.85 moles

According to reaction, 1 mole of propane gives 3 moles of carbon dioxide gas.

Then 3.85 moles of propane will give:

\frac{3}{1}\times 3.85 mol=11.55 mol of carbon dioxide gas.

11.55 moles of carbon dioxide gas are formed from 3.85 mole of propane.

According to reaction, 1 mole of propane gives 4 moles of water gas.

Then 3.85 moles of propane will give:

\frac{4}{1}\times 3.85 mol=15.4 mol of water .

15.4 moles of water are formed from 3.85 mole of propane.

b) Moles of oxygen gas = 0.647 moles

According to reaction, 5 mole of oxygen gas gives 4 moles of water.

Then 0.647 moles of oxygen will give:

\frac{4}{5}\times 0.647 mol=0.5176 mol of water.

0.5176 moles of water are formed from 0.647 mole of oxygen gas.

According to reaction, 5 mole of oxygen gas reacts with 1 mole of propane.

Then 0.647 moles of oxygen will give:

\frac{1}{5}\times 0.647 mol=0.1294 mol of propane.

0.1294 moles of propane are consumed.

The molecular mass of methyl ethanoate is 74.1 amu . calculate the molecular mass of propanoic acid, an isomer of methyl ethanoa
kobusy [5.1K]
Isomers are the compounds having same molecular formula but different structural formula. 

Since, molecular formula is isomers are same, they have same mass.

Now, <span>methyl ethanoate is  an isomer of propanoic acid, hence they have same mass.

</span>∴ Molecular mass of propanoic acid = 74.1 amu or 74.1 g/mol<span>

When a known quantity of compound, at a known concentration, is added to a known volume of another compound to determine the con
Vladimir [108]

Answer:

A titration

Explanation:

A common example of a titration is when we have an acid of unknown concentration, so we add a known volume of a base of known concentration. This process lets us determine the concentration of the acid.

By definition, a titration is a quantitative analysis, as we determine how much of an analyte is there in a sample. However, <u>there are quantitative analyzes which are not titrations</u>. This is why the most appropiate answer is<em> a titration</em>.
