The charge of the ion, HPO₄⁻² is equal to -2. This is the same as the one written before it as it appears in the formula of the substance. Since, in the given chemical formula, HPO₄ does not have any multiplier, the charge of the atom or ion that should appear before it is +1. The atoms that will have a charge of +1 are those in group A1. These are Na+, Li+, K+, Rb+, Cs+ and Fr+.
A. The water will freeze. This is because if there's not enough heat, water will freeze. Just like in winter. There's not enough heat to keep the water from melting, so it just freezes. Hope this helps!
Answer: A nuclear accident
Explanation:
The Chernobyl nuclear accident is level 7 (according to the International Nuclear Event Scale)<u>, due to the high impact that caused serious consequences on the environment and living beings.</u>
It should be noted that what happened in Chernobyl is considered one of the largest nuclear disasters in human history, because after the accident a large cloud with radioactive particles was found at a high altitude, scattering radiation all over the planet.
Furthermore, it is important to note that although the survival of wildlife in the Chernobyl region has currently been observed and some people still visit the site and others live there, the presence of humans in the place is prohibited.
