Answer:
Explanation:
pure bleach b/c that is was helps destroy the bacteria
After transferring cultures with any equipment, it is best to immerse the equipment in pure bleach. Bleach is a strong disinfectant that can efficiently destroy various types of microorganisms.
After using loops, swabs, toothpicks, spreaders or any other equipment to transfer cultures, the equipment should ideally be immersed in pure bleach. This is because pure bleach effectively destroys many types of microorganisms found in these cultures. Pure bleach is a strong disinfectant that kills bacteria, viruses, and fungi, reducing the risk of spreading these organisms in the lab. Pouring bleach over the equipment can remove most of these organisms, but immersion guarantees thorough decontamination.

Just had this question, oxygen is the correct answer
b. liquids.
c. malleable.
d. gases.
Answer : At room temperature, none of the metals are gases.
Explanation :
The properties of metals are :
Generally all the metals are solid at room temperature but with exception, the mercury is liquid at room temperature.
Generally all the metals are hard but with the exception, sodium and potassium are soft and easily cut with the knife.
The metals are malleable, ductile, lustrous in nature.
Metals are good conductor or heat and electricity.
Hence, At room temperature, none of the metals are gases.
Answer: Option (d) is the correct answer.
Explanation:
It is known that most of the metals are solid at room temperature but with a few exceptions like mercury is a liquid at room temperature and sodium is a soft metal as it can be cut with a knife.
Also, metals are malleable in nature that is, they can be shaped into thin sheets.
But metals are never gases. Hence, we can conclude that at room temperature, none of the metals are gases.
(3) KCl(aq) and H2O(ℓ)
(4) KOH(aq) and Cl2(g)
B.) Shape
C.) Color
D.) Volume
(2) ethanol (4) water
The compound that has the lowest vapor pressure is ethanoicacid. The correct option is 1.
Vapor pressure is a measure of a material'stendency to change into a gaseous or vapor state, and it rises with temperature.
The boilingpoint of a liquid is the temperature at which the vapor pressure at its surface equals the pressure exerted by its surroundings.
A liquid with weak intermolecularforces evaporates faster and has a higher vapor pressure. A liquid with stronger intermolecular forces is more difficult to evaporate and thus has a lower vapor pressure.
At 50°C, ethanoloicacid has the lowest vapor pressure, which is 0.08 atm. Propanone has a vapor pressure of 0.84 atm at 50°C. At 50°C, ethanol has a vapor pressure of 0.30 atm.
Thus, the correct option is 1.

Answer : Option A) Ethanoic Acid
Explanation : Ethanoic acid has the lowest vapor pressure i.e 0.08 atm at the temperature of 50°C compared to the other given options.
The vapour pressure of propanone at 50°C is 0.84 atm
Ethanol has vapour pressure as 0.30 atm at 50°C
water has vapour pressure of 0.12 atm at 50°C.
