You will be adding a solution containing potassium carbonate to a solution containing hydrochloric acid. What risk is associated

Phantasy [73]

Explanation:

The reaction of potassium carbonate with hydrochloric acid is as follow -

Potassium Carbonate + Hydrochloric acid → Potassium Chloride + Water + Carbon Dioxide.

In the above reaction , the metal carbonate reacts with an acid to give salt , water and carbon dioxide .

The reaction is an exothermic reaction , as the release of carbon dioxide , is indicated by vigorous effervescence .

Hence ,

The temperature of the reaction increases a lot and hence the reaction is very dangerous .

Therefore , the reaction is very risky to perform.

A sample of an ideal gas has a volume of 0.500 L at 25 degrees celcius and 1.20 atm pressure. What is its volume at 75 degrees c

NemiM [27]

The ideal gas law is PV= nRT.
First you need to manipulate the equation to splice for volume,
Which will be V= nRT/P

Now you need to input the numbers for each variable. Make sure to remember what the value R equals and it’s units. R= 0.08206 L•atm/n•K

<h3>Explanation:</h3>

<u>Step 1: Define</u>

[RxN - Unbalanced] Mg + N₂ → Mg₃N₂

[RxN - Balanced] 3Mg + N₂ → Mg₃N₂

[Given] 1.22 g Mg

[Solve] grams Mg₃N₂

<u>Step 2: Identify Conversions</u>

[RxN] 3 mol Mg → Mg₃N₂

[PT] Molar Mass of Mg - 24.31 g/mol

[PT] Molar Mass of N - 14.01 g/mol

Molar Mass of Mg₃N₂ - 3(24.31) + 2(14.01) = 100.95 g/mol

<u>Step 3: Stoich</u>

[DA] Set up: $\displaystyle 1.22 \ g \ Mg(\frac{1 \ mol \ Mg}{24.31 \ g \ Mg})(\frac{1 \ mol \ Mg_3N_2}{3 \ mol \ Mg})(\frac{100.95 \ g \ Mg_3N_2}{1 \ mol\ Mg_3N_2})$
[DA] Multiply/Divide [Cancel out units]: $\displaystyle 1.68873 \ g \ Mg_3N_2$

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

1.68873 g Mg₃N₂ ≈ 1.69 g Mg₃N₂
