If 5g of H2 are reacted with excess CO, how many grams of CH3OH are produced, based on a yield of 86%?
Cerrena [4.2K]

Answer: 34.4 g

Explanation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

\text{Number of moles of hydrogen}=\frac{5g}{2g/mol}=2.5moles

As CO is in excess, H_2 is the limiting reagent and thus it will limit the formation of products.

CO+2H_2\rightarrow CH_3OH

According to stoichiometry:

2 moles of hydrogen produce = 1 mole of CH_3OH

2.5 moles of hydrogen produce = \frac{1}{2}\times 2.5=1.25 moles of CH_3OH

Mass of CH_3OH=moles\times {\text {Molar mass}}=1.25\times 32=40g

But as % yield is 86%, mass of CH_3OH produded is \frac{86}{100}\times 40=34.4g

Thus 34.4 g of CH_3OH is produced.

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.
