The correct answer for the question that is being presented above is this one: "A. A sample of 0.500 mole of O2 is added to the 4.80 g of O2 in the container." A sample containing 4.80 g of O2 gas has an initial volume of 15.0 L. The final volume, in liters, when each of the following changes occurs in the quantity of the gas at a constant pressure and temperature is that <span>A sample of 0.500 mole of O2 is added to the 4.80 g of O2 in the container.</span>
Answer:
Heat is something you can't control
Explanation:
Plastic is something you could control like moving it around
Answer:
The correct answer is - both act only between non-atomic particles.
Explanation:
The decreasing order of their relative strength is - the strong force, electromagnetism, weak force, gravity.
so, A would be here = gravity
B would be = weak force
C would be = strong force
The weak and strong forces both are fundamental forces that act on sub-atomic particles only such as quarks.
Answer:
The sun's circumference is about 2,713,406 miles (4,366,813 km). It may be the biggest thing in this neighborhood, but the sun is just average compared to other stars. Betelgeuse, a red giant, is about 700 times bigger than the sun and about 14,000 times brighter.
Explanation:
looked it up
Answer: The molality of solution is 17.6 mole/kg
Explanation:
Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.
where,
n = moles of solute
= weight of solvent in kg
moles of acetone (solute) = 0.241
moles of water (solvent )= (1-0.241) = 0.759
mass of water (solvent )=
Now put all the given values in the formula of molality, we get
Therefore, the molality of solution is 17.6 mole/kg
