The significant zeros in the following numbers are given below;
- 0.000067800 - all zeros except the last two
- 3068800000 - all zeros
- 4000600.00 - all zeros except the ones after the decimal point
<h3>What are significant zeros?</h3>
Significant figures of a number in positional notation are digits in the number that are reliable and necessary to indicate the quantity of something.
To determine whether or not a zero in a number is significant or not, the following rules are applied:
- Non-zero digits are always significant
- Any zeros between two significant digits are significant
- A final zero or trailing zeros in the decimal portion only are significant
This suggests that the following applies to the following numbers;
- 0.000067800 - all zeros except the last two
- 3068800000 - all zeros
- 4000600.00 - all zeros except the ones after the decimal point

Answer:
1= weather
2= climate
3=climate
4= climate, i think
5= weather
6= weather
7= climate
8=weather
9= weather
10= weather
hope this helps!
Explanation:
weather is typically over a short period, climate is over a long time.
<span>a) Oxidation state of Ba in reactant: 0
In product: +2.
</span><span>Oxidation state of Zn in reactant: +2.
In product: 0.
</span><span>Oxidation state of S in reactant: +6
In product: +6.
</span><span>Oxidation state of O in reactant: -2.
In product: -2.
This is redox reaction because elements change their oxidation states (barium and zinc).
</span>b) Oxidation reaction: Ba⁰ → Ba²⁺ + 2e⁻.
Reduction reaction: Zn²⁺ + 2e⁻ → Zn⁰.
c) Barium is oxidized (increase of oxidation number) and zinc is reduced (decrease of oxidation number).
d) <span> The oxidizing agent is zinc (gain electrons) and the reducing agent is barium (lose electrons).</span>
Hi,
the answer should be the last one, ‘neither accurate nor precise’.
The values are quite different from one another and not close to the actual value.
Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistake.
