Answer: we started with 10 ions of Mg and 20 ions of F.

Explanation: The given balanced equation is:

MgCl_2(aq)+2AgF(aq)\rightarrow 2AgCl(s)+MgF_2(aq)

From this balanced equation, 2 formula units of AgCl are formed by 2 formula units of AgF and 1 formula unit of MgCl_2 .

From here, the ratio between AgCl and AgF is 2:2 that is 1:1 and the ratio between AgCl and MgCl_2 is 2:1 ,

Since the ratio between AgCl and AgF is 1:1, 20 formula units of AgCl will be formed by 20 formula units of AgF.

The ratio between AgCl and MgCl_2 is 2:1, so 20 formula units of AgCl will be formed by 10 formula units of MgCl_2 .

One formula unit of MgCl_2 contains one ion of Mg, so 10 formula units of MgCl_2 will contain 10 ions of Mg.

Similarly, 1 formula unit of AgF contains one ion of F, so 20 formula units of AgF will contain 20 ions of F.

So, we started with 10 ions of Mg and 20 ions of F to make 20 formula units of AgCl.

<span>We started with twenty ions of Mg and twenty ions of F. Producing 20 units of AgCl requires twenty MgCl2 since it is the only source of magnesium. Similarly it requires twenty AgF since it is the only source of silver.</span>

Chemistry to make tomato soup, you add one can of water to the condensed soup. why is this dilution?
Nastasia [14]
Dilution refers to decreasing the ratio of total solution to the reference solution by the addition of other liquids. By adding water to tomato soup, the balance of “tomato soup” molecules decreases from 100% tomato soup, to eventually 1:1 TS and Water (50%), and so on. Chemically, you can observe this as decreasing the concentration of tomato soup in this solution.

Whats a type of researcher that uses computer to make sense of complex digital data
geniusboy [140]

Answer:

Data Scientist

Explanation:

Data Scientist (different from a statistician) is a type of researcher that uses computer softwares to analyse and make sense of raw digital data.

Data Scientists usually combine knowledge of computer science, statistics and mathematics while using various softwares to extract information and meaningful, key insights (whether structured or unstructured) from data.

There are two popular types of data scientists: Operational Data Scientists (experts in software implementations and day to day running of the data science wing of a firm) and Exploratory Data Scientists (The real digital data miners, the researchers).

With the way the world is set up now that data is everything, data scientists are a must for every firm as the raw data every firm collects is processed by data scientists.
