Explain why is it better to use images on hazard labels, rather than words
enot [183]
In the case of an emergency where you might not have enough time to read several lines of writing, not to mention trying to find the hazard warnings when the whole bottle is probably covered in writing, it is much easier to locate and read universal hazard symbols.

. In which reaction is nitric acid acting as an oxidising agent?
Talja [164]

Answer:

B. Cu + 4HNO3 → Cu(NO3)2 + 2H2O + 2NO2

Explanation:

Hello,

In this case, we should understand oxidizing agents as those substances able to increase the oxidation state of another substance, therefore, in B. reaction we notice that copper oxidation state at the beginning is zero (no bonds are formed) and once it reacts with nitric acid, its oxidation states raises to +2 in copper (II) nitrate, thus, in B. Cu + 4HNO3 → Cu(NO3)2 + 2H2O + 2NO2 nitritc acid is acting as the oxidizing agent.

Moreover, in the other reactions, copper (A.), sodium (C. and D.) remain with the same initial oxidation state, +2 and +1 respectively.

Regards.

Explain the correlation between chemical properties and chemical changes. (plz i not sure on the answer so it would mean a lot i
Snezhnost [94]

Answer:

Explanation:

A chemical property describes the ability of a substance to undergo a specific chemical change.

A chemical reaction is a process that occurs when one or more substances are changed into one or more new substances.

Differences

Chemical properties are properties that can be observed or measured when a substance undergoes a chemical change.

Physical properties are properties that can be observed without bringing a chemical change.

Another one

chemical properties; can be used to predict how substances react.

chemical changes; It is mostly used in identifying or describing the substance.
