Answer:
120G
Explanation:
From the combustion process, about 120G of carbon dioxide would be released into the atmosphere.
For the chemical reaction to obey the law of conservation of matter, if only ash and carbon dioxide are the product, then the sum of the mass of the product and that of the reactants must be the same.
In a chemical reaction, matter is not created nor destroyed, but they are simply changed from one form to another.
Mass of wood burning = mass of ash + mass of CO₂
150G = 30G + mass of CO₂
mass of CO₂ = 150G - 30G = 120G
This is an complete question, here is a complete question.
Consider the following standard reduction potentials in acid solution:
The weakest reducing agent listed above is:
(a) 
(b) 
(c) 
(d) 
Answer : The correct option is, (d)
Explanation :
As we know that,
The substance having highest positive 
potential will always get reduced and will undergo reduction reaction and weakest reducing agent or strongest oxidizing agent.
From the standard reduction potentials we conclude that,
having highest positive potential than the other. So, it will always get reduced and will undergo reduction reaction and weakest reducing agent.
Hence, the correct option is, (d)
Answer:
1. Zn + HCl --> ZnCl + H2
2. when zinc reacts with hydrochloric acid, the zinc gets oxidized as chlorine is an electronegative element while the hydrochloric acid gets reduced as their is a removal of chlorine from the compound to give out hydrogen
3. it happens in our stomach as it releases hcl in the undigested food to convert it into soluble compounds and waste material for consumption by our body and excretion respectively.
Answer:
A Punnet Square...the second I am not sure.
Explanation:
Unfortunately the second could be many things. You'd have to have more background information.
