Chemistry
1 answer:
scZoUnD [109]3 years ago
5 0

Answer:

grams of solute = 31.5 g

Explanation:

Given data:

Grams of solute = ?

%m/v  = 3%

Volume = 1050 mL

Solution:

grams of solute = 3 g of NH₄Cl / 100 mL × 1050 mL

grams of solute = 0.03 g × 1050  

grams of solute = 31.5 g

So 31.5 g are needed to to make 3% m/v solution.

What mass of oxygen is needed to combust and produced 6.4 moles of carbon dioxide gas?
N76 [4]
You have already gotten the balanced equation. And the ratio of mol number of reactants and production is the ratio of coefficient. So there is 6.4/8*11=8.8 mol oxygen needed. The mass is 8.8*32=281.6 g.

Identify some other substances (besides KCl) that might give a positive test for chloride upon addition of AgNO3. Based on the r
SashulF [63]

Answer:

Other substances that give a positive test with AgNO3 are other chlorides present, iodides and bromide. However iodides and bromides have different colours hence they will not give a false positive test for KCl. Other chlorides present may lead to a false positive test for KCl.

Explanation:

In the qualitative determination of halogen ions, silver nitrate solution is used. Various halide ions give various colours of precipitate with silver nitrate. Chlorides yield a white precipitate, bromides yield a cream precipitate while iodides yield a yellow precipitate. All these ions or some of them may be present in the system.

However, if other chlorides are present, they will also yield a white precipitate just as KCl leading to a false positive test for KCl. Since other halogen ions yield precipitates of different colours, they don't lead to a false test for KCl. We can exclude other halides from the tendency to lead us to a false positive test for KCl but not other chlorides.
