Explanation:
Burning of alcohol produces different products as it depends on the type and nature of alcohol which is being burnt.
Some alcohols upon burning produce toxic gases or products whereas some alcohols on burning does not produce any toxic substances.
For example, when ethanol is burnt then it reacts with oxygen and results in the formation of water and carbon dioxide.
Thus, we can conclude that the statement burning alcohol for fuel is a very efficient process is a false statement.
binary fission
detection of light
detection of danger
The euglena's red eyespot is used for detection of light.
Answer:
binary fission
Explanation:
A solution base differs from a solution of an acid in that the solution of a base has lesser hydrogen ion concentration than the solution of an acid. It is known that acids compounds contains hydrogen and produces hydrogen ion in water. A binary acid however is an acid that have two elements, one of the element has a hydrogen attached to it. Examples of binary acids are hydrogen fluoride (HF), hydrogen bromide (HBr) and hydrogen sulfide (H2S). In naming a binary acid, it has two rules; one, as pure compounds and two, as acid solutions.

Answer:
Explanation:
In an artificial transmutation, atoms of one element are artificially made to strike other particles with in an accelerator. Usually in an Artificial transmutation, there are particle accelerators that bombard the elements with in them using alpha particles, deuterons etc.
This bombarding causes lodging of certain elements into the targeted nucleus, thereby forming a new and a different element.
For example -
In the first artificial transmutation, Helium nucleus was bombarded on nitrogen nucleus thereby producing new nuclei and a proton.
H2 + O2 -> H2O
If 20 g of hydrogen is reacted with 32 g of oxygen to produce 9 g of water, the percentage yield is 5%.
Percent yield is the ratio of the actual yield times the theoretical yield to 100. When the actual and theoretical yield are equal, the percentage yield is 100%. So if the actual yield is less than the theoretical yield then the percentage yield is less than 100%. This situation may arise due to the incompleteness of the reaction or the loss of the sample during the recovery process.
According to the stoichiometry of reaction of formation of water,
4 g hydrogen gives 36 g water, thus, 20 g hydrogen gives 20×36/4=180 g water which is theoretical yield.
So, the percent yield=observed yield/theoretical yield×100
percent yield=9/180×100=5%.
Thus, if 20 g of hydrogen is reacted with 32 g of oxygen to produce 9 g of water, the percentage yield is 5%.

Answer:
12.5%
Explanation:
32/16 = 2 moles of oxygen
2 x 18.01 x 2/1 = 72.04 g of H2O
9/72.04 x 100 = 12.5%
balanced equation: 2H2 + O2 → 2H2O
limiting reactant is oxygen
A = 9.60 M
B = 10.0 M
C = 4.00 M
D = 4.00 M
Answer : The value of equilibrium constant is, 0.166
Solution : Given,
Concentration of A = 9.60 M
Concentration of B = 10.0 M
Concentration of C = 4.00 M
Concentration of D = 4.00 M
The equilibrium reaction will be,
The expression for equilibrium constant is,
Now put all the given values in this expression, we get the values of equilibrium constant.
Therefore, the value of equilibrium constant is, 0.166
