Answer:
A)The total number of protons plus neutrons= Weight of an atom
The answer is A. large differences between their boiling points
Answer:
hi
Explanation:
There is enough energy in air at room temperature to change some liquids to gases. The temperature of ice water is lower than the temperature of dry ice in alcohol. Carbon dioxide can change directly from the solid phase to the gaseous phase. ... Absolute zero is the temperature at which there is no molecular motion.
Answer: True
Based on the dissolution equation of BaSO4, the solubility product, Ksp, expression of BaSO4 is: [Ba^{2+}] × [SO4^{2-}]
<h3>What is solubility product Ksp of a solute?</h3>
The solubility product, Ksp, of a substance is an equilibrium constant which expresses the product of the concentration of ions produced by a solute.
The solubility of a solute depends on temperature, thus solubility product also depends on temperature.
The balanced equation for the dissolution of barium sulfate is given below:
- BaSO4 ⇌ Ba^{2+} + SO4^{2-}
The solubility product for barium sulfate is given as;
Ksp = [Ba^{2+}] × [SO4^{2-}]
Therefore, the solubility product, Ksp, expression of BaSO4 is: [Ba^{2+}] × [SO4^{2-}]
