Answer: Eggshells have a similar chemical composition to our tooth enamel, making them react similarly with other chemicals. This can help us understand what stains tooth enamel. When we brush an eggshell with fluoridated toothpaste, it strengthens the shell and protects it from acid, just like it does for our tooth enamel
Explanation:
The equilibrium constant is a ratio of the concentration of the products raised to their respective stoichiometric coefficients to the concentration of the reactants raised to their respective stoichiometric coefficients. For this reaction, K is equal to
K = [N₂O₅]/[NO₂][NO₃]
So, if K is greater than 1, the reaction would favor the product side. Otherwise, it would favor the reactant side. Since the K here is less than 1 as manifested by the negative exponent of 10, the reaction would favor or would be spontaneous for the forward reaction.
A is correct. water is incompressible, so it will always have the same density, regardless of volume
Explanation:
small amount of solute is dissolved in a large amount of solvent. it would not make sense to have more solute and solvent. you can think of it like this, you can dissolve a teaspoon of salt in a litre water but you can't resolve 1 kg of salt in a teaspoon of water.
also, the solute is what is begin dissolved and the solvent is what dissolving the solute so the one day the solvent is dissolved in the solute does not make complete sense.
The PROTON (<em>option D</em>) is the positively charged sub-atomic particle in the nucleus.
