Metals are found in group 1, 2, and abit of 3.
Non-metals are found in group 0/8, abit in 4, 5, 6 and 7 too. Here is a picture. Most of the periodic table are metals.
The number of mole of carbon dioxide, CO₂ formed from the reaction is 0.0632 mole.
<h3>How to determine the mole of NaHCO₃</h3>
- Molarity of NaHCO₃ = 2 M
- Volume = 31.6 mL = 31.6 / 1000 = 0.0316 M
- Mole of NaHCO₃ =?
Mole = Molarity x Volume
Mole of NaHCO₃ = 2 × 0.0316
Mole of NaHCO₃ = 0.0632 mole
<h3>How to determine the mole of CO₂</h3>
NaHCO₃ + HCl —> CO₂ + H₂O + NaCl
From the balanced equation above,
1 mole of NaHCO₃ reacted to produce 1 mole of CO₂.
Therefore,
0.0632 mole of NaHCO₃ will also react to produce 0.0632 mole of CO₂.
Thus, 0.0632 mole of CO₂ was obtained from the reaction

The slogan is " understanding literature through synthesis". Check more about the importance of writing below.
<h3>What is the importance of synthesis in writing?</h3>
Synthesis is known to be the one that uses both information that has been paraphrased and also the one where the writer uses other information obtained from a lot of sources.
Note that Synthesis depicts more about scholarship as well as it also tell more about an understanding literature and other kind of information.

Answer:
D Reasoning.
Explanation:
The key here is that it involves scientific investigation. This must be done without bias or personal history, which only serve to taint the results. Mythology is a religion and has no place in the interpretation of scientific results.
Answer:
-2 and -12
Explanation:
A dilation is a transformation of a geometric image that is known to change its size not it shape.
The size of the figure basically depends on the scale factor (k).
When k >1 then there would be expansion.
When k <1 then there would be contraction.
When k=1 then no change in size
I.e for conraction the scale factor (k) must be negative
from the given options, the scale factor produce a contraction under a dilation of the original image would be -2 and -12
<h3 /><h3>Hence the correct answers are:-2 and -12 </h3>
