Answer:
2.70 M.
Explanation:
Molar mass of MgO = 24.3 + 16 = 40.3.
A molar solution will contain 40.3g in 1 Litre.
So 800 mL of 1 molar solution will contain 0.8* 40.3 g MgO.
So the molarity of the given solution
= 87 / (0.8*40.3)
= 2.699 M.
We are tasked to solve for the volume of the gas that occupies when pressure and temperature changes to 400 Torr and 200 Kelvin from Torr and 400 Kelvin. We can use ideal gas law assuming constant gas composition and close system. The solution is shown below:
P1V1 / T1 = P2V2 / T2
V2 = P1V1T2 / T1P2
V2 = 800*72*200 / 400*400
V2 = 72 ml
The answer for the volume is 72 ml.
Answer:
Fungi are a food source for animals and humans. This point do not apply on fungi.
Explanation:
Roles of fungi:
Penicillin and Cephalosporins are the antibiotics made by fungi. They are natural sources of antibiotics.
Fungi are eaten by animals examples are mushroom, agaricus and some animals even eat poisonous mushrooms.
Fungi destroy by releasing chemicals into the rock and they get iron this way and then deeply burrow the rocks and harming them.
Fungi acts as a decomposer to nourish the soil and improves vegetation.
Many infections are caused by fungus like ringworm infection, candida and Athlete's food are some examples.
