The right answer is 2HgO → 2Hg + O2
Balancing a balance equation consists of finding the right stoichiometric coefficients. These coefficients (placed in front of each molecule) balance the number of each of the different atoms involved during a chemical reaction.
In this reaction, we find on both sides the same number of atoms: two oxygen atoms and two atoms of mercury.
The correct answer to the
question above is:

Since ratio means the quantitative relationship between two
values which the frequency of one value is contained within the second value.
In this case, it is only 1:1 which means that whatever the number indicated in
the first value is equal to the second value.
A plant called duckweed might be a viable option to remove phosphorus, nitrates, and heavy metals from rivers and lakes.
Answer:
each place on Earth weather data have been collected
Explanation:
The mathematical modelling is a set of equations that are developed to determine the effect of some phenomena. The environmental phenomena may include something like the rain patterns in the tropics, the temperature changes in the next 10 years, and the wind patterns in the next years. In the weather model, each place on Earth weather data have been collected will be used to see how the trends change over the course of time.
