Sugar dissolves readily in water because it is a(n) ____ substance.
Mnenie [13.5K]
The answer to this question would be D. Hydrophilic.

The word hydrophilic mean attracted by water. That means the molecule has a force to attract water molecule, thus be able to dissolve in water.  The polarity of the molecule would determine whether a molecule hydrophilic or not.
Its opposite would be hydrophobic which the molecule can't dissolve in water.  One example of this would be oil or fat. That is why sometimes it is called lipophilic too.

The relative atomic mass of Chlorine is 35.45. Calculate the percentage abundance of the two isotopes of Chlorine, 35Cl and 37Cl
nata0808 [166]

Answer:

35Cl = 75.9 %

37Cl = 24.1 %

Explanation:

Step 1: Data given

The relative atomic mass of Chlorine = 35.45 amu

Mass of the isotopes:

35Cl = 34.96885269 amu

37Cl = 36.96590258 amu

Step 2: Calculate percentage abundance

35.45 = x*34.96885269 + y*36.96590258

x+y = 1  x = 1-y

35.45 = (1-y)*34.96885269 + y*36.96590258

35.45 = 34.96885269 - 34.96885269y +36.96590258y

0.48114731 = 1,99704989‬y

y = 0.241 = 24.1 %

35Cl = 34.96885269 amu = 75.9 %

37Cl = 36.96590258 amu = 24.1 %

When the equation BiCl3 + H2S → Bi2S3 + HCl is the coefficient of HCl will be
Alina [70]
The product Bismuth (III) sulfide (Bi_{2}S_{3}) is used as a starting material for the synthesis of other bismuth compounds. It is formed, together with an acid, from a reaction between a Bismuth (III) salt and hydrogen sulfide (H_{2}S). In the given reaction, the Bismuth salt used in the reaction is Bismuth (III) chloride (BiCl_{3}). 

The balanced reaction of BiCl_{3} and H_{2}S is

2BiCl_{3} + 3H_{2}S --> Bi_{2}S_{3}+ 6HCl

Thus, the coefficient of HCl in the reaction is 6.

An insoluble solid is placed in water and the system allowed to reach equilibrium. The ratio of the rate at which ions join the
babunello [35]

Answer:

One.

Explanation:

Hello,

In this case, the equilibrium condition is characterized by the equality of the rates at which a process happen and the contrary process happen, so its ratio is 1. For instance, a chemical reaction at equilibrium will have a contant ratio of the velocity at which the products are formed and the reactants consumed

However, for the described insoluble solid that is allowed the reach equilibrium, the ratio of the rate at which ions join the solution and the rate at which ions join the lattice will be one since it reaches an equilibrium state.

Best regards.
