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.

Explain the main cause of degradation of our languages in belize? it's science but I put biology​
Nonamiya [84]

Language degradation is occurring because of the adoption of foreign languages.

<h3>How does this adoption take place?</h3>

The constant presence of foreign media and the adoption of foreign language terms is the main way to adopt a new language.

This adoption allows the local population to start mixing the two languages.

Over time this process becomes more intense, causing the local language to be replaced by a foreign language over time.

Language degradation is a process that occurs in many regions, but maintaining these languages is very important.

Jake wants to enrich the nitrogen content of his soil through fixation. Which crop can he use for this purpose? wheat sugarcane
inn [45]
The appropriate answer is D. Alfalfa. Alfalfa is a legume and these plants play a key role in the nitrogen cycle. These plants house nitrogen fixing bacteria on their roots. The bacteria are housed in tiny round structures of leguminous plant roots. Once the nitrogen is fixed in the soil it can now be used by other plants to make food.  These plants include beans peas and peanuts.  <span />

Marianna [84]

Answer:

1. Sexual Reproduction

2. Genetic variations

Explanation:

Human reproduces through sexual reproduction. Sexual reproduction is the process of production of new progeny by the formation of male and female gametes (sperms and egg respectively) and fusion of gametes. During gamete formation, crossing over adds new gene combinations to the gametes. The genetic variations make the progeny of sexual reproduction different from each other and from the parents.
