Answer:
3 (c)
Explanation:
All matter has density becuase all matter takes up space. When you wave your hand infront of yourself you feel wind. if air did not take up space it would all collapse into a black hole becuase their would be no resistance.
Wolf gang polli made the polli exlution princible, it says that all fermion particles take up space and can not be in the same place at the same time. This is why your legs hold up, your Piano doesent fall through the ground. if this wassent true everything would collaps into a black hole
Hope it helped
Answer:
0.5667 M ≅ 0.57 M.
Explanation:
It is known that the no. of millimoles of a solution before dilution is equal to the no. of millimoles of the solution after the dilution.
It can be expressed as:
(MV) before dilution = (MV) after dilution.
M before dilution = 1.5 M, V before dilution = 340 mL.
M after dilution = ??? M, V after dilution = 340 mL + 560 mL = 900 mL.
∴ M after dilution = (MV) before dilution/(V) after dilution = (1.5 M)(340 mL)/(900 mL) = 0.5667 M ≅ 0.57 M.
It’s C. 0.31 atm
I hope this helped out! Have a nice day :)
The answer is B. is the energy source of stars.
Fission is the type of nuclear energy simulated on Earth, as it is the one used to generate electricity. Fusion, on the other hand, is much more complicated to achieve because it requires extremely hot temperatures compared to fission. Fusion involves the combination of two hydrogen atoms to make helium, which releases a lot of energy. Stars such as the sun, exhibit fusion with its very hot temperature and abundant source of hydrogen.
Answer:
Option C. hydroxide ions (OH-).
Explanation:
A base is a substance which dissolves in water to produce hydroxide ion (OH-) as the only negative ion. It therefore means that a base contains more hydroxide ions (OH-).
