Answer:
0.6139M
Explanation:
A 3.50% by mass of NaCl means there are 3,50g of NaCl in 100g of solution. To find molarity we need to convert the mass of NaCl to moles and mass of solution to liters as follows:
<em>Moles NaCl -molar mass: 58.44g/mol-:</em>
3.50g NaCl * (1mol / 58.44g) = 0.05989 moles of NaCl
<em>Liters solution:</em>
100g solution * (1mL / 1.025g) * (1L / 1000mL) = 0.09756L of solution
<em>Molarity -Ratio of moles and liters-:</em>
0.05989 moles of NaCl / 0.09756L of solution =
<h3>0.6139M</h3>
Answer:
Na F
Explanation:
because electrovalent bond is present between them
The rate of increase of NH3 is 0.22M/s.
<h3>What is the balanced equation of the reaction?</h3>
The balanced equation of the reaction is given below:
- N2(g) + 3 H2(g) → 2 NH3(g)
The rate of decrease of N2 is half the rate of increase of NH3.
Rate of decrease of N2 = -0.11 M/s
Rate of increase of NH3 = 2 × +0.11 M/s = 0.22M/s.
In conclusion, the rate of formation of products is dependent on the rate of disappearance of reactants.

Answer:
The strength of an acid refers to how quickly the hydrogen ions present are able to dissociate. The concentration of an acid refers to the amount of hydrogen ions present compared to water. Therefore, an acid can be described as both strong and dilute as it may have less hydrogen ions that dissociate quickly.
