Suppose the mass of a jelly bean is less than the mass of a gum drop. If you counted out 10 of each kind of candy and measured t

he mass of each kind of candy, the mass of the jellybeans would be less than the mass of the gumdrops. more than the mass of the gumdrops. the same as the mass of the gumdrops. hard to determine based on the information given.

Answer: Option (a) is the correct answer.

Explanation:

Since it is given that the mass of a jelly bean is less than the mass of a gum drop.

So, when we counted out 10 of each kind of candy and measured the mass of each kind of candy, the mass of the jellybeans would be less than the mass of the gumdrops.

This is because mass of jelly bean is less and even if we take take or more jelly beans then also their total mass will remain less than the total mass of same number of gum drops.

If metal ions in a solution were reduced, what would you expect to see?
marysya [2.9K]

Answer:

Solid metal

Explanation:

The reduced form of metal ions is the metal in elemental state (simple substance). So, if you have a solution with metal ions and they are reduced, you probably will see the deposition of the metal. For example: if you have a solution with sodium ions (Na⁺), and the ions are then reduced, you will see the aparition of a solid phase of metallic sodium (Na(s)), according to the following half-reaction:

Na⁺ + e- → Na(s)

at a particulat temperature, a smaple of pure water has a Kw of 7.7x10-14. what is the hydroxide concentration of this sample
ycow [4]

Answer: The hydroxide concentration of this sample is 3.85\times 10^{-7}

Explanation:

When an expression is formed by taking the product of concentration of ions raised to the power of their stoichiometric coefficients in the solution of a salt is known as ionic product.

The ionic product for water is written as:

K_w=[H^+]\times [OH^-]

7.7\times 10^{-14}=[H^+]\times [OH^-]

As [H^+]=[OH^-]

2[OH^-]=7.7\times 10^{-14}

[OH^-]=3.85\times 10^{-7}

Thus hydroxide concentration of this sample is 3.85\times 10^{-7}
