Answer:
B
Explanation:
We are talking about the periodic table in which elements where put under different rows and columns according to their atomic number (number of protons) in ascendant order.
In rows or periods we can find trends in some properties like atomic radius, electronegativity, etc...). So they are not similar in size. Option A is a false statement.
Also, they were organized in groups or columns according to their similar electronic configuration and chemical properties (like noble gases, halogens, etc...) This means option B is the correct statement.
Answer;
Taxes
A disadvantage of corporations is that shareholders have to pay taxes on profits.
Explanation;
A corporation or public corporation is a form of business unit that is a legal entity, which in usually organized under the laws of a state, and whose investors or share holders purchase shares of stock as evidence of ownership in it.
One of the disadvantages of corporation is double taxation; A corporation may pay taxes on its income, after which the investors or the shareholders pay taxes on dividends earned, and therefore it means the income has been taxed twice.
Explanation:
Temperature has a direct relationship with reaction rate. The higher the temperature the faster the rate of reaction of a system.
- For every 10°C rise in temperature above the room temperature, it has been found that reaction rates becomes double or triple.
- When the temperature of a reacting system increases, the kinetic energy of each of the reacting particles increases.
- The frequency of collision and effective collision also increases per unit of time.
- Many of the reacting particles will acquire an energy greater than or equal to the activation energy of the reaction.
Because all atoms are made from the same particles which are protons, neutrons, and electrons.
