Answer:
Explanation:
1. Virus's are hard to detect because of their simple construction.
2. Some mutate very easily.
3. It is hard to isolate the virus and kill it without doing damage to the host.
The volume of the entire object
Answer: CH
Explanation:
The empirical formula represents the simplest whole number ratio of atoms of all the elements present in a compound. So empirical formula of C6H6 is “CH”.
Since the choices are not listed, it would be difficult to identify what is really the answer. The best I could do is to list some of the environmental consequences of the use of nuclear energy. This type of energy is said to have the lowest impact on the environment since it does not have eany emission that would cause air pollution, its waste is isolated from the environment and would only need a small amount of area of land. Although it has the lowest impact, it would still have an effect on the environment. One would be the amount of radiation that will be emitted when a meltdown would happen. This would affect not only the environment but all of the living things including humans. Also, it could cause eutrophication from the wastes. <span />
The partial pressures of gases in air at 760 mmHg are N₂ (592.8 mmHg), O₂ (159.6 mmHg) and Ar (7.6 mmHg).
<h3>What is partial pressure?</h3>
Partial pressure is the pressure of a gas in a mixture of gases.
Air is a mixture of gases with 78% N₂, 21% O₂, 1% Ar and other gases in trace amounts. The partial pressure of a gas is proportional to its percentage.
Let's calculate the partial pressures of these gases, considering that the atmospheric pressure is 760 mmHg.
pN₂ = 760 mmHg × 78% = 592.8 mmHg
pO₂ = 760 mmHg × 21% = 159.6 mmHg
pAr = 760 mmHg × 1% = 7.6 mmHg
The partial pressures of gases in air at 760 mmHg are N₂ (592.8 mmHg), O₂ (159.6 mmHg) and Ar (7.6 mmHg).
