Answer:
= 15.51 mL
Explanation:
Here's is the reaction:
2HgO(s) ⇒ 2 Hg(s)+O₂(g)
In this reaction 2mol HgO = 1mol O₂
The molecular weight of HgO = 216.59g
so, 3.0g HgO = 3.0g x 1.00molHgO/216.59gHgO
= 0.0138511 molHgO
The amount of Oxygen follows:
0.0138511 molHgOx1/2= 0.00692555 mol O₂
Now, volume of 1 any gas = 22400mL
so, 0.00692555 mol O₂ x22400mLO₂/1mol O₂
= 15.513232mL O₂
Hey mate!
Taxonomy is the <span>study of classification of organisms. Therefore, your answer is A.

There will be oil bubbles because oil is more dense than water so therefore they would not mix
<u>Answer</u>: Light
<em>Computer is an example of light energy which is the third option out of the given four choices.
</em>
<u>Explanation:</u>
We know how a computer works it takes in <em>the electrical energy</em> and does a <em>lot of mathematical mechanical work</em> and for giving answers. It uses a screen on which light blinks in pattern such that it represents letters or mathematical numbers or expressions.
Hence by using this statement we can say <em>computer converts electrical energy into light energy.
</em>
Answer:
1552.83J Released
Explanation:
1. mass/m=225
Initial temp:86C, final:32.5C
Changed Temp: 32.5-86= -53.5C
s=0.129 J/gC
Formula: q= m times s times changed Temp.
q=(225)(0.129)(-53.5)
q= -1552.83 J
q=1552.83 J Released
