Consider the following reaction: NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2 How many mol of CO2 would be produced from the complete
Assoli18 [71]

Answer:

0.208mole of CO2

Explanation:

First, let us calculate the number of mole of HC3H3O2 present.

Molarity of HC3H3O2 = 0.833 mol/L

Volume = 25 mL = 25/100 = 0.25L

Mole =?

Mole = Molarity x Volume

Mole = 0.833 x 0.25

Mole of HC3H3O2 = 0.208mole

Now, we can easily find the number of mole of CO2 produce by doing the following:

NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2

From the equation,

1mole of HC2H3O2 produced 1 mole of CO2.

Therefore, 0.208mole of HC2H3O2 will also produce 0.208mole of CO2

why can an increase in temperature lead to more effective collisions between reactant particles and an increase in the rate of a
Tasya [4]
The reason why is because particles are moving faster and possess greater kinetic energy due to the increase in temperature, this causes greater frequency or number of collisions to take place and also allows for a higher likelihood that upon reactant molecules colliding they will undergo the reaction process as they will have achieved the required energy needed for the reaction to start. Thus overall having a greater change in quantity conversion of reactants to products within a shorter period of time, thus increasing the reaction rate.

Are elements matter and why?
nata0808 [166]

All matter is made up of substances called elements, which have specific chemical and physical properties and cannot be broken down into other substances through ordinary chemical reactions. Gold, for instance, is an element, and so is carbon. There are 118 elements, but only 92 occur naturally.
