<u>Answer:</u> The amount of water produced is 18 moles.

<u>Explanation:</u>

The given chemical reaction follows:

2C_8H_{18}(g)+25O_2(g)\rightarrow 16CO_2(g)+18H_2O(g)

By Stoichiometry of the reaction:

2 moles of octane gas reacts with 25 moles of oxygen gas to produce 16 moles of carbon dioxide gas and 18 moles of water molecule.

Number of water molecules produced = 18 moles

Hence, the amount of water produced is 18 moles.

Determine whether the following reaction is a Lewis acid/base reaction and if so, what is the Lewis acid: Fe3+(aq) + 6 CN−(aq) →
Aleonysh [2.5K]

Answer: It is a Lewis acid/base reaction, and Fe^{3+} is the Lewis acid.

Explanation:

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

Fe^{3+} can readily accept electrons and thus act as a lewis acid which is short of electrons.

CN^- can readily lose electrons and thus act as a lewis base which has excess of electrons.

It is a Lewis acid/base reaction, and Fe^{3+} is the Lewis acid.

The element antimony has two stable isotopes, antimony-121 with a mass of 120.90 amu and antimony-123 with a mass of 122.90 amu.
NARA [144]

Answer:

antimony-121 has the highest percent natural abundance

Explanation:

percent natural abundance;

121.76 = 120.90 x + 122.90 (1 - x)

121.76 = 120.90 x + 122.90 - 122.90x

121.76 = -2x + 122.90

121.76 - 122.90 = -2x

x= 121.76 - 122.90/ -2

x= 0.57

Where x and 1 - x refers to the relative abundance of each of the isotopes

Percent natural abundance of antimony-121 = 57 %

Percent natural abundance of antimony-123 = (1 - 0.57) = 43%

Let us remember that isotopy refers to a phenomenon in which atoms of the same element have the same atomic number but different mass numbers. This results from differences in the number of neutrons in atoms of the same element.

We can clearly see that antimony-121 has the highest percent natural abundance.

3. A leaky faucet drips at the rate of 300 mL per hour. How many liters will drip in a
ki77a [65]

Answer:

Hence , in a century<u> 0.342 liters</u> of the liquid will drip.

Explanation:

The rate of the flow of the liquid droplet is given by:

Rate=\frac{Volume}{time}

Rate=\frac{mL}{hr}

<u>Unit conversion:</u>

We need to change mL/hr into Liter/century

1 L = 1000 mL (given)

1 mL = 0.001 L......(1)

1 century = 100 year

1 year = 365 days

So, 1 century = 100 x 365 days = 36500 days

1 day = 24 hrs

So , 36500 days = 36500 x 24 hr = 876000 hr

Hence ,

1 century = 36500 days = 876000 hr

we are not asked to calculate the answer in days

1 century = 876000 hr

1 hr = 1/ 876000 century

1 hr =1.141\times 10^{-6}.....(2)

From (1) and (2) put the value in the given formula:

This is for 1 mL/hr to 1 L/century

Rate=\frac{mL}{hr}

Rate=\frac{0.001\ L}{1.141\times 10^{-6}century}

Rate=1.141\times 10^{-3}L/century

Now for 300 mL/hr . the rate will be more , multiply the answer by 300

Rate=300\times 1.141\times 10^{-3}L/century

Rate = 0.342 Liters / century

Hence , in a century 0.342 liters of the liquid will drip.
