Data flows can be highly consistent, with periodic peaks, making data loads hard to manage. This feature of big data is called variability.

Data flow in Big Data is called Velocity or process speed.

Management of data that is structured in Big Data is called a Variety or types of data that can be accommodated.

<h2>Further explanation </h2>

Big data is a term that describes a large volume of data, both structured and unstructured that floods everyday business.

Big Data has three main characteristics:

  • Volume. The volume here is related to the size of the data storage media which is very large or may be unlimited. Big data has a very large amount of data so that the data processing requires large storage and more specific analysis is needed.
  • Velocity. Velocity here is a very fast speed at which data is received and (possibly) directly used. Usually, the highest speed of data flow is directly to memory compared to that written to disk. Some smart devices that use the internet operate in real-time or near real-time and will require real-time evaluation and action.
  • Variety. Variety in question here are the various types of data available. Traditional data types are usually more structured. With the development of big data, there is also unstructured data. Unstructured or semi-structured data such as text, audio, and video take time to process so you can know the meaning of these data.

Some things that are considered as big data are the following:

  • Internet use
  • Smartphone usage
  • Social media
  • Digitalization of media
  • Smart device

Here are some things that can be done with Big Data:

  • Customer relationship management (CRM)
  • Help your business operations become more efficient
  • Improve user mobile experience
  • Encourage innovation

There are five main steps to taking over this large "data structure" that includes traditional and structured data along with unstructured and structured data:

  • Set a big data strategy.
  • Identify the source of big data.
  • Access, manage and save data.
  • Data analysis.
  • Make decisions based on data.

The ph of a solution that contains 0.818 m acetic acid (ka = 1.76 x 10-5) and 0.172 m sodium acetate is __________.
crimeas [40]
PH is calculated using <span>Handerson- Hasselbalch equation,

                                      pH  =  pKa  +  log [conjugate base] / [acid]

Conjugate Base  =  Acetate (CH</span>₃COO⁻)
Acid                    =  Acetic acid (CH₃COOH)
So,
                                      pH  =  pKa  +  log [acetate] / [acetic acid]

We are having conc. of acid and acetate but missing with pKa,
pKa is calculated as,

                                     pKa  =  -log Ka
Putting value of Ka,
                                     pKa  =  -log 1.76 × 10⁻⁵

                                     pKa  =  4.75
Now,
Putting all values in eq. 1,
                     
                                     pH  =  4.75 + log [0.172] / [0.818]

                                     pH  =  4.072

If a 0.10 M solution of a colored substance has a maximum absorbance at 500 nm and an absorbance of 0.26 M at this wavelength, w
Mashcka [7]
Absorbance is related to the concentration of a substance using the Beer-Lambert's Law. According to this law, absorbance is linearly related to concentration. However, this is only true up to a certain concentration depending on the substance. For this case, we assume that the said law is applicable.

A = kC
Using the first conditions, ewe solve for k.
0.26 = k (0.10)
k = 2.6

A = kC
A = 2.6 (0.20) = 0.52

Therefore, the absorbance at a concentration of 0.20 M and wavelength of 500nm is 0.52.

How many chloride ions are in 0.486 moles of chloride ions?​
svetlana [45]

Answer:

Since in a chloride ion, we have an additional electron

you might think that it will affect the mass but the mass of an electron is almost negligible so we will ignore that

Amount of ions in 1 mol = 6.022 * 10^23

Amount of ions in 0.486 moles = 0.486 * (6.022*10^23)

Amunt of ions in 0.486 moles = 2.9 * 10^23 ions

Hence, option 1 is correct

The atomic radius of magnesium is 150 pm. The atomic radius of strontium is 200 pm. What is the atomic radius of calcium
Anon25 [30]

Answer:

The atomic radius of calcium is approximately 175

Explanation:

Given that the atomic radius of magnesium = 150 pm

The atomic radius of strontium = 200 pm

Therefore, given that calcium comes in between magnesium and strontium in group 2 of the periodic table, the atomic radius should be half way between the length of the atomic radius of magnesium and strontium, given that the atomic radius is not a fixed quantity

Therefore;

The atomic radius of calcium is approximately given as follows;

The approximate atomic radius (200 + 150)/2 = 175 pm.

In science class, Blaine’s teacher puts one glow stick in a cup of hot water and another glow stick in a cup of cold water. She
timofeeve [1]

Answer:

The glow stick in hot water will be brighter

Explanation:

The glow stick in hot water will be brighter than the glow stick in cold water because the heat from the hot water will cause the molecules in the glow stick to move faster. The faster the molecules move in the glow stick, the sooner and brighter the reaction will be. The cold water will cause molecules to move slowly and it will take longer for the reaction to occur, which will also make it less bright.
