What mass of each solute is present in 294 g of a solution that contains 4.86% by mass NaCl and 7.54% by mass Na2CO3
Angelina_Jolie [31]
In order to compute the mass of each solute in the sample, we simply multiply the percentage mass of each solute with the total mass of the solution. This is ad such:
Mass (NaCl) = 0.0486 x 294
Mass (NaCl) = 14.29 grams

Mass(Na₂CO₃) = 0.0754 x 294
Mass(Na₂CO₃) = 22.17 grams

Hydrogen peroxide, H2O2, decomposes according to the equation above. This reaction is thermodynamically favorable at room temper
s2008m [1.1K]

Answer:

4H₂O₂ → 4H₂O + 2O₂

Explanation:

The chemical reaction for the decomposition of hydrogen peroxide can be represented as follows;

2H₂O₂ → 2H₂O + O₂

Therefore, two molecules of hydrogen peroxide decomposes into two molecules of water and one molecule of oxygen.

In a related diagram, we have 4 molecules of hydrogen peroxide decomposing, therefore we have;

4H₂O₂ → 4H₂O + 2O₂

The attached diagram shows the products of the decomposition of the four molecules of hydrogen peroxide.

What is the measurement 1042 L rounded off to two signicant digits ?
SOVA2 [1]
This is a really hard question. Because if you change it to 1,000 then that's only one. If you add the decimal so it's 1,000. , then that's 4 if you change it to 1,040, that's 3. So you can not change that to 2 significant digits.
