If we use the next formula to determine this:<span>ΔQ=mcΔT
Then we can get to the result. Be</span>cause of the conservation of energy, the quantity of heat remains the same.
So what we do is:<span><span>c1</span>∗<span>m1</span>∗(<span>T1</span>−<span>T∗</span>)=<span>c2</span>∗<span>m2</span>∗(<span>T∗</span>−<span>T2</span>)</span><span>
when plugging in 0.39 for copper and 4.19 we get 29°C for the resulting temperature. I hope this can help you</span>
Answer:
Option A. 2, 3, 2
Explanation:
We'll begin by balancing the equation. This can be achieved by doing the following:
Fe + Cl2 —> FeCl3
There are 2 atoms of Cl on the left side and 3 atoms on the right side. It can be balance by putting 3 in front of Cl2 and 2 in front of FeCl3 as shown below:
Fe + 3Cl2 —> 2FeCl3
There are 2 atoms of Fe on the right side and 1 atom on the left side. It can be balance by putting 2 in front of Fe as shown below:
2Fe + 3Cl2 —> 2FeCl3
Now the equation is balanced.
The coefficients are : 2, 3, 2
<u>Answer</u>:
"weathering breaks rocks into minerals and plants die and decay" must occur to form soil
<u>Explanation</u>:
For the formation of the soil two process are mandatory and they are erosion as well as weathering. The weathering takes place near the surface of the soil, which can occur due to various physical and chemical processes. Being an important part of soil development. It may occur rapidly or can be a slow process for decades. Water and air helps in weathering. The transport is generally by wind or with the help of flow of water, ice, etc

15mL because if it started as 20 mL and went to 35mL when u put in pyrite, the pyrite takes up 15mL
