Answer:

nitrite ion is NO2- and nitrate ion is NO3-

Explanation:

The nitrite ion has two oxygen atoms and one nitrogen atom while nitrate ion has three oxygen atoms and one nitrogen atom. They are both univalent negative anions that form compounds with metallic cations as shown below;

Na+ + NO3- ⇒ NaNO3 (sodium nitrate)

Na+ + NO2- ⇒ NaNO2 (sodium nitrite)

Ca2+ + NO3- ⇒ Ca(NO3)2 (calcium nitrate)

Ca2+ + NO2- ⇒ Ca(NO2)2 (calcium nitrite)

You can deduce from the above ionic equations that nitrate ion is NO3- while nitrite ion is NO2-.

Answer: The molecular formula will be $C_2H_4O_2$

Explanation:

If percentage are given then we are taking total mass is 100 grams.

So, the mass of each element is equal to the percentage given.

Mass of C = 40.0 g

Mass of O = 53.3 g

Mass of H = 6.66 g

Step 1 : convert given masses into moles.

Moles of C = $\frac{\text{ given mass of C}}{\text{ molar mass of C}}= \frac{40.0g}{12g/mole}=3.33moles$

Moles of O = $\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{53.3g}{16g/mole}=3.33moles$

Moles of H = $\frac{\text{ given mass of H}}{\text{ molar mass of H}}= \frac{6.66g}{1g/mole}=6.66moles$

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For C = $\frac{3.33}{3.33}=1$

For O = $\frac{3.33}{3.33}=1$

For H = $\frac{6.66}{3.33}=2$

The ratio of C : O : H = 1: 1: 2

Hence the empirical formula is $COH_2$

The empirical weight of $COH_2$ = 1(12)+1(16)+2(1)= 30g.

The molecular weight = 60 g/mole

Now we have to calculate the molecular formula.

$n=\frac{\text{Molecular weight }}{\text{Equivalent weight}}=\frac{60}{30}=2$

The molecular formula will be= $2\times CH_2O=C_2H_4O_2$

For Gay-Lussac's law, temperature is measured in _____.

Thepotemich [5.8K]

For Scientist Joseph Louis Gay-Lussac's law, temperature is measured on an absolute scale, specifically Kelvins or k. The formula may be expressed in P/T=k (P over T equals k). The answer to this question is 'kelvins'. I hope this helps.

A quantity of gas has a volume if 400.0 ml when confined under a pressure of 600.0mm Hg. What will be the new volume of the gas

den301095 [7]

Answer:

1200 mL

Explanation:

Step 1:

Data obtained from the question. This includes the following:

Initial volume (V1) = 400 mL.

Initial pressure (P1) = 600 mmHg.

Final volume (V2) =..?

Final pressure (P2) = 200 mmHg

Step 2:

Determination of the final volume i.e the new volume of the gas.

Considering the question given, we understood that the temperature is constant. Therefore the gas is obeying Boyle's law. Using the Boyle's law equation, the new volume is obtained as follow:

P1V1 = P2V2

600 x 400 = 200 x V2

Divide both side by 200

V2 = (600 x 400) /200

V2 = 1200 mL

Therefore, the new volume of the gas is 1200 mL.
