B. Accumulating clutter on the lab bench 
Goshia [24]3 years ago
3 0

The correct option is B.

There are many housekeeping rules that one has to observe when one is working in the laboratory in order to ensure safety. One of these rules is that one should take precaution not to accumulate clutters on the work bench. Littering the work bench with clutters will limit the amount of space that one has to work and these clutters can constitute dangers, for instances, clutter can hinder access to emergency equipment during emergency situations. It is important that laboratory working bench should be kept clean and tidy at all time.

A voltaic cell has a zinc anode and a copper cathode. They are connected by a wire but no salt bridge. What can you predict will
Allisa [31]

The prediction is that B. The electrons will flow to the zinc anode where a negative charge will build up and eventually halt the reaction.

<h3>What is zinc?</h3>

This is known as a chemical element, of the periodic table, that is essential to life and is one of the most widely used metals. Zinc is of considerable commercial importance.

Without the salt bridge, positive and negative charges will build up around the electrodes causing the reaction to stop.

Hence, we know that the purpose of the salt bridge is to keep the solutions electrically neutral and allow the free flow of ions from one cell to another.

The volume of a gas is the same as its _____.
AleksandrR [38]

Gases generally has no shape and no definite volume. When a gas is placed in a container, the gas usually takes the shape and the volume of the container, that is, the gas fills up all the available spaces in the container. Thus, the volume of a gas will always be the same as its container. This is in contrast with solids, which have definite shape and volume and liquids, which have definite volume but no fixed shape.
