2AgNO3 (aq) + Na2CO3 (aq) --> Ag2CO3 (s) + 2NaNO3 (aq)
2Ag(+) (aq) + CO3(2-) (aq) --> Ag2CO3 (s)
hope it helps
Answer: 72 grams of 
are needed to completely burn 19.7 g 
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number 
of particles.
To calculate the number of moles, we use the equation:
Putting in the values we get:
According to stoichiometry:
1 mole of 
requires 5 moles of oxygen
0.45 moles of require= 
moles of oxygen
Mass of 
72 grams of are needed to completely burn 19.7 g
It would have to be 40.0 only because it wouldn’t add up
Answer:
The fossil evidence of both an ocean and a forest can be found at different depths in the same location because there might have been a presence of both an ocean and a forest at the same location at different times in the history of Earth.
Explanation:
It is clear from various studies that the Earth has had a diverse geologic history in which events like drastic climate changes, upsurging of oceans, rapid desertification, etc., have taken place many times.
Thus, the possibility of an ocean and forest having shared a single location at different times in the history of Earth cannot be neglected.
Answer:
carbon dioxide
Explanation:
Carbon dioxide -
The gas carbon dioxide has a molecular formula of CO₂ ,
During the burning process of the fossil fuels , carbon dioxide is resealed in numerous amount , which act as a greenhouse gas .
Greenhouse gas - Are the gases which absorbs and release radiation , and are responsible for the greenhouse effect .
The greenhouse gases are - carbon dioxide , water vapor , methane , ozone , nitrous oxide .
