Changing the concentration of one or more of the reactants can affect the rate of a reaction. This is TRUE, as it means there are more collisions between particles and therefore a higher probability of successful collisions, which speeds the reaction up.
Using the reactants in a fine, powder form rather than a large, chunky form will increase the rate of a chemical reaction as the surface area of the reactants will increase. Therefore, there is a higher probability of successful collisions, which speeds the reaction up.
A catalyst works by increasing the activation energy needed for a reaction. This is TRUE, and the catalyst itself is not used up.

Write 0.000443200 to two significant figures
Tju [1.3M]
0.00044


Zeros to the right of the decimal place are not significant UNLESS they are found in between or after a non-zero number, therefore, we take the 3200 away because those ARE significant so then after you round your answer (if needed) you're left with only two numbers that are significant.

What is the percent yield of LiCl if I produced 30.85g LiCl and my theoretical yield was calculated to be 35.40g LiCl?
marissa [1.9K]

Answer:

87.15%

Explanation:

To find percent yield, we can use this simple equation

\frac{Actual}{Theoretical} *100

Where "Actual" is the amount in grams actually collected from the reaction, and "Theoretical" is, well, the theoretical amount that should have been produced.

They give us these values, so to find the percent yield, just plug the numbers in.

\frac{30.85}{35.40} *100\\\\ =87.15

So, the percent yield is 87.15%

An easy trick to remember how to do this is just to divide the smaller number by the bigger number and move the decimal back two places. If you have a percent yield greater than 100%, something is wrong in the reaction.

What is the happens in electrolysis if the electrolyte solidifies?​
lidiya [134]

Answer: For example, if electricity is passed through molten lead bromide, the lead bromide is broken down to form lead and bromine. This is what happens during electrolysis: Positively charged ions move to the negative electrode during electrolysis. ... Negatively charged ions move to the positive electrode during electrolysis.
