Which statement concerning spontaneous chemical reactions is true?

Chemistry
1 answer:
Marina CMI [18]4 years ago
7 0
I believe the correct answer is b since a spontaneous reaction is self sufficient and should not need an ongoing out side source in order to proceed once it is started.  

a is false since some reactions that occur are relatively slow such as iron reacting with oxygen to make rust.

c is false since most reactions involve an energy change of some sort which is why we classify them as endothermic or exothermic.

d is false since catalysts help speed up reactions but do not really affect a the Gibbs free energy value which determines the spontaneity of the reaction.

PLEASE HELP<br> Describe two physical characteristics of ionic compounds.
RUDIKE [14]

Answer:

High melting points and boiling points

Aqueous solutions are good conductors of electricity

Explanation:

The oppositely-charged ions have strong attractions for each other, so it takes much energy to separate them.

When the ions are the molten state or in aqueous solution, they are free to move towards the oppositely-charged electrodes. The movement of charge constitutes an electric current.

stepan [7]

Answer:

B. Controlled variables

Explanation:

The Dependent sample t-test compares the mean score of measurements in one group to that of another other group. It mainly used when analyzing comparable sample units as it pairs repeatable observations within a time frame.

Controlled variables are factors that are not tested and remain constant. Some examples of controlled variables are temperature, pressure, volume etc
