<u>Answer:</u> The correct answer is option B. electron.
<u>Explanation:</u>
There are 3 subatomic particles:
- Electrons: They carry negative charge and are present in orbits around the nucleus of an atom.
- Protons: They carry positive charge and are present inside the nucleus of an atom
- Neutrons: They does not carry any charge and are present inside the nucleus of an atom.
An atom forms an ion, when it looses or gains an electron.
- When an atom looses electron, it form a positive ion known as cation.
- When an atom gains electron, it form a negative ion known as anion.
Hence, the correct answer is option B. electron.
Answer: (a) The reaction mixture will proceed toward products.
Explanation:
Equilibrium constant is defined as the ratio of pressure of products to the pressure of reactants each raised to the power their stoichiometric ratios. It is expressed as
K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
For the given chemical reaction:
The expression for is written as:
Thus as , the reaction will shift towards the right i.e. towards the product side.
Answer:
C.
Explanation:
The heat island effect or the the urban heat island effect, is where the temperature of an area is higher than close rural areas. This is because materials suh and concrete and asphalt absorb the sunlight and store it, causing extreme weather.
Answer:
E. The number of moles of solute in both solutions is the same.
Explanation:
The dilution of a solution consist in increase the volume of solution decreasing, thus, the concentration of the solution. The moles of solute doesn't change in a dilution process.
Thus, when a solution is diluted, the relationship of the number of moles of solute in the more concentrated initial volume of solution to the number of moles of solute in the less concentrated final volume of solution is that:
E. The number of moles of solute in both solutions is the same. TRUE.
