Answer:
2600 kg has 4 significant figures
Explanation:
Any different number to zero is a significant figure
For example, 1.8 → 2 significant figures
When you have 0 in the middle of two numbers, we consider it as a significant number
For example, 3.02 → 3 significant figures
When you have 0 on the left in the measure, we do not consider as a sgnificant figures
For example 0.0010 → 2 significant figures (10)
3.0 → 2 significant figures (0 is on the right, not the left)
A lot of cooking involves chemistry and is essentially a series of chemical reactions. Knowing about this kitchen chemistry can help you to understand much more about what’s happening – and why your recipes sometimes go wrong.Bananas turning brown is kitchen science.Why curry is hot uses chemical formulas.What happenes when meat cooks involves chemical formulas.Why popcorn pops inovopves chemical formulas.And,why honey is good for sore throats involves chemical formulas.

Mangoes contain beta carotene, which lends their interiors a beautiful yellow hue. Beta carotene is a phytochemical. Mangoes are packed with carotenoids, which are produced using phytoene. The phytoene leads to an integration of orange-yellow carotenoids, thereby turning mangoes yellow.
Answer:
Fe
Explanation:
The cell potential is:
ΔE°cell = E°red(red) - E°red(oxid)
Where, E°red(red) is the reduction potential of the substance that is reducing, and E°red(oxid) is the reduction potential of the substance that is oxidizing. For the reaction be spontaneous and happen, ΔE°cell > 0.
The reduction takes place in the cathode, which is the negative pole, and the oxidation in the anode, which is the positive pole. So, the electrons flow from the positive pole to the negative pole (anode to cathode).
Then, if the voltmeter measured a negative potential, it means that is was attached incorrectly. So, the anode is Fe.
