Earths climate history <br> Short writing

ra1l [238]

Answer:

Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.

Explanation:

In short words , Earths climate went from cold this is due because ; of the global Ice Age. After the rock showers hit it released large amounts of carbon it heated up the atmosphere causing the word to have bacteria and grow livable life-forms again. 2021 we are producing too much carbon and this is leading factor of climate change not only is the earth already warm enough but its rapidly heating up. An example of this is ETC - "I live in CA and since the start of Autumn we haven't had and glimpse or foreshadowing of cold weather its been 80* everyday and hasn't dropped one bit not even in the morning."

Consider the word equation. Calcium hydroxide hydrochloric acid mc012-1. Jpg calcium chloride water Which is the corresponding f

dimulka [17.4K]

The corresponding formula equation is:

Upper Ca (upper OH) subscript 2 (s) plus 2 upper H upper Cl (l) right arrow upper Ca upper Cl subscript 2 (aq) plus 2 upper H subscript 2 upper O (l)

To obtain the word equation, we shall write out the balanced molecular equation. This is given below:

Calcium hydroxide => Ca(OH)₂

Hydrochloric => HCl

Calcium chloride => CaCl₂

Water => H₂O

Calcium hydroxide + Hydrochloric —> Calcium chloride + water

Ca(OH)₂ + HCl —> CaCl₂ + H₂O

There are 2 atoms of Cl on the right side and 1 atom on the left. It can be balance by writing 2 before HCl as shown below:

Ca(OH)₂ + 2HCl —> CaCl₂ + H₂O

There are a total of 4 atoms of H on the left side and 2 atoms on the right side. It can be balance by writing 2 before H₂O as shown below:

Ca(OH)₂ + 2HCl —> CaCl₂ + 2H₂O

Now, the equation is balanced.

Thus, the corresponding word equation is:

Upper Ca (upper OH) subscript 2 (s) plus 2 upper H upper Cl (l) right arrow upper Ca upper Cl subscript 2 (aq) plus 2 upper H subscript 2 upper O (l)
