Answer:
7 sig figs.
Explanation:
Hello,
By performing the given operation:
![12.34*56.78](https://tex.z-dn.net/?f=12.34%2A56.78)
The result is:
![12.34*56.78=700.6652](https://tex.z-dn.net/?f=12.34%2A56.78%3D700.6652)
Thus, we notice that 700.6652 has five non-zero digits which are eligible for significant figures. Moreover, those two zeros after the 7 also are eligible for significant sigures as they are to the right of the first non-zero digit (7). Therefore, the result contains seven (7) significant figures.
Best regards.

It tells you what method she used and what she wanted to accomplish. She is using
<em>an absolute dating method to study a sample of basalt</em>
So the answer you should post is F. F and the quotation above say the same thing.
The balanced equation for the redox reaction, which takes place in a basic solution is:
- 2 Cr(OH)₃ + ClO₃⁻ (aq) + 4 OH⁻ → 2 CrO₄²⁻ (aq) + Cl⁻ (aq) + 5 H₂O; <u>option C</u>
<h3>What is the balanced equation for the redox reaction?</h3>
A balanced equation for a redox reaction is one in which the electrons transferred are balanced and the atoms involved in the reaction are also balanced.
To balance redox reactions in a basic solution, OH⁻ ions and H₂O are placed on appropriate sides of the reaction.
Considering the given reaction:
Cr(OH)₃ + ClO₃⁻ (aq) → CrO₄²⁻ (aq) + Cl⁻ (aq):
The balanced equation will be:
2 Cr(OH)₃ + ClO₃⁻ (aq) + 4 OH⁻ → 2 CrO₄²⁻ (aq) + Cl⁻ (aq) + 5 H₂O
The electrons transferred and the atoms involved are balanced.
