Answer:

it is D

Explanation:

NaOH and chlorine gas

Electrolysis of Aqueous NaCl Since water can be both oxidized and reduced, it competes with the dissolved Na+ and Cl– ions. Rather than producing sodium, hydrogen is produced. ... The net process is the electrolysis of an aqueous solution of NaCl into industrially useful products sodium hydroxide (NaOH) and chlorine gas.

In a lab in New York, Thomas and Nikola collected data over several trials. Thomas recorded his measurements as 10.0 A, 11 A, an

Anna11 [10]

Nikola's reading has a lower range and it is logical to conclude that his reading is more precise.

Explanation:

Precision is the ability to reproduce the same set of result from a measurement. The more repeatability a measurement is, the more precise it is.

From the given pool of data, it is easy to determine which set of data is more precise over the other.

Thomas measurements: 10.0 A, 11 A, and 8 A

Nikola measurements: 9.0 A, 9.2 A, 8.8 A

Using the range method, it is possible to find the precision in this pool of data.

Method and Solution:

Find the range of the sample:

Range = highest value - lowest value

Thomas measurement; Range = (11-8)A = 3.0A

Nikola measurement; Range = (9.2-8.8)A = 0.4A

Find the mean of the samples:

Mean of Thomas measurement = $\frac{10 + 11+ 8}{3}$ = $\frac{29}{3}$ = 9.7A

Mean of Nikola measurement = $\frac{9+ 9.2+ 8.8}{3}$ = $\frac{27}{3}$ = 9A

Now let us quote the range of value of the mean of each measurement:

Thomas 9.7±3.0A

Nikola 9.0± 0.4A

Nikola's reading has a lower range and it is logical to conclude that his reading is more precise.

The process in which energy is converted from solar to chemical and then one form of chemical to another form is photosynthesis. It is a process carried out by the plant to make food. The leaves of the plant take in sunlight, water from the soil and carbon dioxide from the air to produce glucose and oxygen.

What is the name of this hydrocarbon?

jenyasd209 [6]

Answer:

2-methylebutane

Explanation:

it is a hydrocarbon and there is a specific Rule for its nomenclature.

that is known as IUPAC naming system. According to it

The compound that has all single bonds name ends on ane.
Names according to the number of Carbons,

* For one carbon compound it is known as methane,

* For 2 ethane,

* For 3 propane

* For 4 Butane and so on.

select the longest chain of compound
Start numbering with lowest substituted position at carbon
branch compound name as Iso and neo as whole

So keeping in mind the compound can be named as

2-methylebutane

As the longest chain contain four carbon atoms so it will name as butane
The substitution of methyl group is on C-2

*Note: it can also named as isopantane as it is branched and have five carbons but it could not be 3-isopentane.

If the mass of a liquid is 60 g and the volume is measured at 15 ML, what is the density?

Dovator [93]

Answer:

4 g/ml

Explanation:

Density is defined as the amount of a substance (mass) in a certain volume. So the equation is D = m/v.

For this example, D = 60 g/15 ml. so the answer would be 4 g/ml.
