time travel is the best option
Answer:
I don't no this answer do you know then telle
Stirring promotes the reaction by exposing all of the unreacted region of the marble to the acid. Moreover, mixing increases the degree of homogenity within the reaction mixture, meaning the reaction is carried out evenly through out rather than faster in some regions while slower in others.

Answer:
0.00235
Explanation:
- Zeros that come before any non-zero digits are never significant.
- Zeros that are in between any non-zero digits are always significant.
- Zeros that come after any non-zero digit are ONLY significant if a decimal point in present somewhere in the number. (In this case there is a decimal point, but there aren't any zeros at the end of this number.)
The zeros at the beginning aren't significant, so include those zeros in your answer. The 6 at the end in greater than 5 so that rounds the 4 to up one number (In this case, it's 5).
This gives you 0.00235
