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.

3. How many molecules are in 2.10 moles of H2O?
AnnZ [28]

Answer:

<h2>1.264 × 10²⁴ molecules</h2>

Explanation:

The number of molecules can be found by using the formula

N = n × L

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

N = 2.10 × 6.02 × 10²³

We have the final answer as

<h3>1.264 × 10²⁴ molecules</h3>

Hope this helps you

The conjugate acid of ch3nh2 is ________. the conjugate acid of ch3nh2 is ________. ch3nh2+ ch3nh2 ch3nh3+ ch3nh+ none of the ab
Verizon [17]
The conjugate acid of ch3nh2 is ch3nh3+<span>.
</span>For example methylamine in water chemical reaction: 
CH₃NH₂(aq)+ H₂O(l) ⇌ CH₃NH₃⁺(aq) + OH⁻(aq).
According to  Bronsted-Lowry theory acid are donor of protons and bases are acceptors of protons (the hydrogen cation or H⁺). Methylamine (CH₃NH₂) is Bronsted base and it can accept proton and become conjugate acid (CH₃NH₃⁺).
