what is the density of a 5 mL sample of 1.95g of Gold

Answers

Answer:

density=mass/volume

=1.95/5 = 0.39 g(mL)-¹

Part A
In the year 2012, an estimated amount of 31.6 billion metric tons (1 metric ton = 1000 kg) of carbon dioxide (CO2) was emitted worldwide due to fossil fuel combustion
and cement production. Express this mass of CO2 in grams without exponential notation, using an appropriate metric prefix

Answers

The mass of CO₂ in grams without exponential notation and with the appropriate metric prefix is 31.6 Eg.

First, let's calculate the amount of mass in grams of 31.6 billion metric tons.

Knowing that 1 metric ton is equal to 1000 kg, 31.6 billion metric tons is:

[tex]m = \frac{1000 kg}{1 \: metric \: ton}*\frac{1000 g}{1 kg}*31.6 \cdot 10^{12} \: metric \: ton = 3.16 \cdot 10^{19} g[/tex]

The metric prefix that is close to the above result is exa (E), which is equal to 10¹⁸.

Therefore, the mass of CO₂ in grams without exponential notation and with the appropriate metric prefix is 31.6 Eg (exa-gram).

10 advantages of atomic absorption spectrometer over flame photometer

Answers

Answer:

(1) It does not suffer from spectral interference, which occurs in flame emission spectroscopy.

(2) By atomic absorption technique, traces of one element can easily be determined in presence of high concentration of other elements.

The technique makes use of the atomic absorption spectrum of a sample in order to assess the concentration of specific analytes within it. It requires standards with known analyte content to establish the relation between the measured absorbance and the analyte concentration and relies therefore on the Beer–Lambert law.

Acrylonitrile and ethyl acetate have the same boiling point: 77.2ºC. In one to two sentences, explain what outcome you would expect if a mixture of these two substances were distilled (SHORT ANSWER)

Answers

Acrylonitrile and ethyl acetate will be collected together since they both have the same boiling point.

The method of distillation highly depends on the difference between the boiling points of the Acrylonitrile and ethyl acetate.

Since they have the same boiling point, the two substances turn into vapor at the same temperature and are collected simultaneously.

Hence separation is not achieved by distillation.

Answer:

19.278049929737628457607385688801

Explanation:

Volume = L * W * H

Volume = 17.78 * 9.21 * 4.45 = 728.70441

Density = Mass / Volume

Mass = 14,048

14,048 / 728.70441 = 19.278049929737628457607385688801

Density = 19.278049929737628457607385688801

Explanation:

So density = mass/volume

Using this formula we'll solve the question.

mass = 14,048g/1000 = 14.048 kg

volume = 17.78/100 x 9.21/100 x 4.45/100

volume = 0.3143 m³

density = 14.048 kg/ 0.3143 m³

density = 44.69 kg/m³

round off to = 44.7 kg/m³

How can the Swartz process be modified to work for bacteria? Explain.

Answers

Answer:

https://swartzbiotechnologylab.sites.stanford.edu/research

Explanation:

Alkyl chlorides and alkyl bromides are typically transformed into alkyl fluorides in the organic reaction known as the Swarts Reaction.

Swartz reaction?

Frederick Jean Edmond Swarts first reported this procedure in 1892. Heating the alkyl chloride or alkyl bromide in the presence of heavy metal fluorides like AGF, Hg2F2, CoF2, or SbF3 causes this reaction.

Swartz process can be used to modify work for bacteria. Bacterial biofilms are collections of microorganisms where the cells are immersed in an extracellular polymeric matrix that the bacteria have self-produced.

In contrast to planktonic bacteria, which are in a state of free movement in a bulk solution, this situation is very different.

Applications:

In this process, alkyl fluorides are created.Fluorinated aliphatic organic molecules, or Freons, are produced via a different variation of the same process.Anhydrous hydrogen fluoride is fluorinated to produce Freons in the presence of antimony salts, which exhibit the oxidation states +3 and +5.

Therefore, Alkyl chlorides and alkyl bromides are typically transformed into alkyl fluorides in the organic reaction known as the Swarts Reaction.

How are electrons arranged around an atom?

Answers

Answer:

Viewed simply, electrons are arranged in shells around an atom's nucleus. Electrons closest to the nucleus will have the lowest energy. Electrons further away from the nucleus will have higher energy.

Answer:

Electrons are placed in the lower energy level first and when this is completely filled, we move on to the second energy level and so on. The way the electrons are arranged in an atom is called the atom's electronic structure or electronic configuration. The maximum number of electrons that the first shell can contain is 2.

Which of the following is a result of increasing the temperature of a system that includes a reaction in the forward direction that is exothermic?
a) The equilibrium constant decreases.
b) The concentrations of the products increase.
c) The equilibrium constant increases.
d) The concentrations of the reactants decrease.

Answers

Answer:

I believe the answer your looking for is out of A or B

Explanation:

Option B because if the heat increases its essentially causing the concentration to increase by replacing the weak bonds with stronger ones

In increasing the temperature of a system that includes a reaction in the forward direction that is exothermic, the concentration rises as weak bonds are replaced by stronger ones.

What is the temperature of a system?

The average kinetic energy of the atoms or molecules in a system is measured by temperature. No heat is transmitted between two objects in thermal equilibrium, according to the zeroth law of thermodynamics.

In conclusion, as the temperature of the system rises, the concentration rises as weak bonds are replaced by stronger ones.
