I don't know what you mean by type of 18, but it is called inorganic chemistry.
Answer:
The answer to your question is: first option.
Explanation:
What is an aqueous solution?
Aqueous solution is a solution which solvent is water and is homogeneous.
a) An aqueous solution is a homogeneous mixture of a substance with water. This is the correct definition of aqueous solution because it mentions the characteristics of this kind of solutions.
b) An aqueous solution is a dispersoid solution. This option is wrong, it is a homogeneous solution, and the description do not mention water.
c) An aqueous solution is a mixture of a liquid substances. Aqueous solution is a mixture but one of the components is water not a liquid substance.
d) An aqueous solution is a heterogeneous mixture of a substance with water. Aqueous solution is homogeneous not heterogeneous, this option is wrong.
Answer:
The limiting reactant is B.
Explanation:
The equation for the reaction is given below:
2A + 3B —> C + D
The limiting reactant can be obtained as follow:
From the equation above,
2 units of A reacted with 3 units of B.
Therefore, 5 units of A will react with = (5 x 3) /2 = 7.5 units of B.
From the calculation made above, we can see that it will take a higher unit of B i.e 7.5 units than what was given i.e 6 units to react completely with 5 units of A.
Therefore, B is the limiting reactant and A is the excess reactant.
PH value of 0.10 m of HBr, a strong acid.
When dissolved in water it gives H+ and Br-, so H+ is the concentration.
pH = - log H+) => pH = - log (0.10) = -(-1) = 1
HF and HC2H3O2 are weak acids. They both will have pH value greater than 1 as they ionize in solution.
Answer:
The amount of sugar in the sample
Explanation:
The independent variable is not dependent on the other observed variable in an experiment. So In this case, it is the amount of sugar as it does not change by the other variable in the experiment, i.e. the number of bees that visit the sample.
The other options are irrelevant in this experiment because they are not being studied.
