I don’t! Know bit I guess it’s C
Answer:
C6 H10 O5+ 6O2-----> 6CO2+5H2O+heat
Explanation:
There are 6 carbon atoms in reactants to balance you put coefficient 6.
This makes the oxygen in CO2 12 so to balance put 6 in oxygen in reactants.
There are 10 hydrogen atoms in reactants to balance you put 5 in front of H2O in products.
If u recheck: 6 C atoms in reactants, 6 C atoms in products.
10 H atoms in reactants, 10 H atoms in products.
17 O atoms in reactants, 17 O atoms in products.
Answer:
a)
b)
Sulphurdioxide
c)
d)
Incomplete combustion produce harmful gases.
Explanation:
a)
Carbon reacts with atmospheric oxygen to form carbondioxide as well as sulphur dioxide.
The chemical equations are as follows.
b)
Sulfur dioxide is very harmful to the environment to cause acid rains.
This harmful gas mix with rain water to form sulphuric acid.
c)
The balanced chemical equation for the reaction that produces harmful environmental effects is as follows.
d)
In the absence of proper amount of oxygen required for combustion, incomplete combustion will take place which will result in formation of more carbondioxide an other harmful gases.
If a hypothesis is not contradicted after a lot of testing, it may be considered a law.
Explanation:
If a hypothesis is not contradicted after a lot of testing, it can be considered a law is a true and correct statement. Laws and theories are completely different approaches in a scientific method.
- Laws are generalized prediction of scientific observations within a limit. Laws holds true when certain parameters are right and correct.
- Theories are explanation of scientific phenomenon. They provide reasons why a certain observation is right or false.
- Both laws and theories are products of hypothesis.
- A hypothesis is a scientific guess or a tentative explanation into an investigation.
- It must be falsifiable, repeated and testable.
- When a hypothesis survives being repeated or tested or falsified, its status is elevated to that of a law or a theory.
