Which of the following techniques is used to separate proteins by function?
Anon25 [30]

Ammonium sulfate precipitation is used to separate proteins by function

However, it is one of the most commonly used methods for laboratory scale protein purification and fractionation. This method is also used to separate proteins by altering their solubility.

<h3>What is separation techniques?</h3>

Separation technique is a process or method used to the components of mixtures.

There are different types of separation technique which includes sublimation, precipitation, sieving, evaporation and many more.

Write the electron configuration diagram that shows the transfer of electrons that takes place to form the compound sodium
Dafna1 [17]

Answer:

See explanation

Explanation:

Now the element sodium has electronic configuration of [Ne]3s1

Florine has an electronic configuration of [He] 2p5

We know that in the formation of sodium flouride, sodium looses one electron to form Na^+ while F gains one electron to form F^-. So the electronic configuration of both Na^+ and F^- now become;  1s2 2s2 2p6

How many moles of CuO are needed to react with 5.9 moles of CO2
Likurg_2 [28]

Answer:

If 5.9 moles of CO₂ react, 5.9 moles of CuO will also react.

Explanation:

The balanced reaction is:

CuO + CO₂ → CuCO₃

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

  • CuO: 1 mole
  • CO₂: 1 mole
  • CuCO₃: 1 mole

You can see that the stoichiometric relationship between CuO and CO₂ is 1: 1. In other words, for each mole of CuO that reacts, one mole of CO₂ will also react.

So <u><em>if 5.9 moles of CO₂ react, 5.9 moles of CuO will also react.</em></u>

what is a major drawback of using fossil fuels they warmn the planet they contain no greenohuse gases
Charra [1.4K]

The major drawback of fossil fuels is that they warm the planet i.e. they cause global warming.

The reaction typically gives off heat and light as well. The general equation for a complete combustion reaction is:

                                  Fuel + O2 → CO2 + H2O + ENERGY

<h3>Disadvantages of Fossil fuels</h3>

The term "fossil fuels" refers to flammable organic geologic formations, including dead organic matter that has been buried hundreds of feet beneath sediment.

  • Fossil fuel emissions include various oxides, such as carbon, nitrogen, and sulfate, which cause acid rain and harm the soil's fertility and water quality.
  • Both coal and petroleum burning discharge a significant amount of pollutants into the atmosphere, contributing to pollution levels.
  • Gases like carbon dioxide are released through the burning of fossil fuels, which aids in climate change.

Sodium is a dull-coloured metal. It is very reactive and must be stored in oil for safety.
Bond [772]

Answer:

Hi there!

It is difficult to remove chlorine out of sodium chloride because in order to separate them you must put that energy into the salt.

Chlorine gas is toxic, and extremely irritating to the eyes and mucous membranes.
