What is the formula for the compound by calcium ions and chloride ions?
dimaraw [331]
To find the ratio of the the combination for the ion, write the charge of the cation as the subscript for the anion, and the charge of the anion as the subscript of the cation. This will make the charges effectively cancel and you will be left with a neutral ionic compound. Remember, that an ionic compound is made up of a metal and a nonmetal.
For Ca2+ and Cl-, you will get the neutral compound to be CaCl₂.

Why was the term inert gases dropped? Why was the term inert gases dropped? The term "inert" was dropped because hydrogen was ad
xxMikexx [17]

Answer:

B) The term "inert" was dropped because it no longer described all the group 8A elements.

Explanation:

Inert elements in chemistry simply refers to elements that are chemically inactive and are not expected to form any compounds. this is the general belief for the group 8 elements as they all have complete duplet/octet configurations (and ideally, they ought to be very stable with no tendency to form compounds by participating in the loss and gain of electrons). However the discovery of compounds like xenon tetrafluoride (XeF4) proved this to be wrong.

Again, the reason the term - inert gses was droppedis beacause this term is not strictly accurate because several of them do take part in chemical reactions.

After dropping the term - Inert gases, they are now referred to as noble gases.

Fossil fuels are considered to be __________ resources because they are consumed ___________ than they form.
mixas84 [53]

Fossil fuels are formed by the deposition of organic matter. It is a nonrenewable resource as they deplete faster as they are produced. Thus, option B is correct.

<h3>What is non-renewable resources?</h3><h3 />

A non-renewable resource is exhaustible and takes a longer time to get produced as they include the accumulation of organic matter over thousands of years.

Fossil fuels take a very long time to get replenished and have a slower rate of formation as compared to consumption. It includes petrol, coal, diesel, natural gases, etc.

Therefore, option B. nonrenewable and far faster are the correct blanks.
