Lungs is an organism can able to take in
The reaction that should be followed is
Na2SO4 + C<span>a(NO3)2 --> CaSO4 + 2NaNO3</span>
first calculate the limiting reactant
mol Na2SO4 = 0.075 L (<span>1.54×10−2 mol / L) = 1.155x10-3 mol
mol Ca(NO3)2 = 0.075 L (</span><span>1.22×10−2 mol / L) = 9.15x10-4 mol
so the limiting reactant is the Ca(NO3)2
so all of the Ca2+ will be precipitated, percentage unprecipitated = 0.00 % </span>
Answer:
See explanation
Explanation:
Freezing point and melting point increases slightly at higher altitude
The boiling point decreases at higher altitudes.
Air pressure decreases with altitude As a result of this, atmospheric pressure decreases and water must now boil at a lower temperature. In order to compensate for this lower boiling point of water, food must take a longer time to cook. The lowering of air pressure actually means that the air becomes thinner at higher altitudes.
Pressure cookers cook food at high pressure thereby reducing the cooking time significantly. This helps to retain 50% of the nutrients in the food, lower the kitchen temperature and lower the energy cost required to cook food.
Explanation:
Liquids cannot change volume but gases can because they have a fixed shape like solids.
Liquids have strong intermolecular forces binding their molecules together resulting is fixed ordering.
- Gases are randomized with their molecules haphazardly arranged.
- This allows them to expand spontaneously on their own.
- Molecules of liquids are more tightly packed compared to gases.
- In a liquid, the molecules have a less random pattern of motion and can only slide past one another.
- In a gas, the molecules are in continuous random, straight line motion.

I believe it has something to do with the H2O molecules, because a chemical compound is not a mixture.
