1. do you think mixing of chlorine powder and oxalic acid is a good practice in laundry or bleaching? how do you say so
Answer:
co2
Explanation:
its because of evaporation
Answer:
Mixing Bleach and Acids
When chlorine bleach is mixed with an acid, chlorine gas is given off. Chlorine gas and water combine to make hydrochloric and hypochlorous acids.
Chlorine gas exposure, even at low levels and short periods of time, almost always irritates the mucous membranes (eyes, throat, and nose), and causes coughing and breathing problems, burning and watery eyes, and a runny nose. Higher levels of exposure can cause chest pain, more severe breathing difficulties, vomiting, pneumonia, and fluid in the lungs. Very high levels can cause death.
Chlorine can be absorbed through the skin, resulting in pain, inflammation, swelling, and blistering. Hydrochloric acid also causes burns to the skin, eyes, nose, throat, mouth, and lungs.
Acid Products
Products containing acids include vinegar and some glass and window cleaners, automatic dishwasher detergents and rinses, toilet bowl cleaners, drain cleaners, rust removal products, and brick and concrete cleaners.
Mixing Bleach with Other Cleaning Products
Bleach also reacts with some oven cleaners, hydrogen peroxide, and some insecticides. Pool chemicals frequently contain calcium hypochlorite or sodium hypochlorite and should not be mixed with other cleaning products.

2. How many molecules of oxalic acid are in 16.5g
SOLUTION:
Step 1: Calculate the molar mass of oxalic acid (H₂C₂O₄).
The molar masses of H, C, and O are 1.008 g, 12.011 g, and 15.999 g, respectively.
[tex]\begin{aligned} \text{molar mass} & = \text{2(1.008 g) + 2(12.011 g) + 4(15.999 g)} \\ & = \text{90.034 g} \end{aligned}[/tex]
Step 2: Calculate the number of molecules of oxalic acid by using dimensional analysis.
There are 6.022 × 10²³ particles in 1 mole of any substance.
[tex]\begin{aligned} \text{number of} \: \text{H}_2\text{C}_2\text{O}_4 \: \text{molecules} & = \text{16.5 g} \: \text{H}_2\text{C}_2\text{O}_4 \times \frac{\text{1 mol} \: \text{H}_2\text{C}_2\text{O}_4}{\text{90.034 g} \: \text{H}_2\text{C}_2\text{O}_4} \times \frac{6.022 \times 10^{23} \: \text{H}_2\text{C}_2\text{O}_4 \: \text{molecules}}{\text{1 mol} \: \text{H}_2\text{C}_2\text{O}_4} \\ & = \boxed{1.10 \times 10^{23} \: \text{molecules}} \end{aligned}[/tex]
Hence, there are 1.10 × 10²³ molecules present in 16.5 g of oxalic acid.

9. Oxalic acid is a diprotic acid. Calculate the percent of oxalic acid (H2C2O4) in a solid, given that a 0.7984 g sample of that solid required 37.98 mL of 0.2283 N Ba(OH)2 for neutralization.
Answer:
This method of quantitative determination of percent purity is titrimetric reactions. These reactions most commonly involve neutralization reactions between an acid and a base. Then, we look at the neutralization reaction: H₂C₂O₄ + 2 NaOH ⇒ Na₂C₂O₄ + 2 H₂O So, we do the stoichiometric calculations. The important data we should know is the molar mass of oxalic acid which is equal to 90 g/mol. (0.2283 mol/L NaOH * 0.3798 L * 1 mol H₂C₂O₄/ 2mol NaOH * 90 g/mol H₂C₂O₄) ÷ 0.7984 g *100% = 488% This is impossible. The purity can't be more than 100%. Looking at our calculations and the balance reaction, all steps were done correctly. So, I think there is some typographical error in the given. The mass of the sample should be 7.984 g. Then, the answer would be 48.87% purity
