Draw a line from each element to the reason for using that element

Ok so I have 3 beakers of clear liquid each holding a different substance, Water, Magnesium Sulphate and Sodium Carbonate how ca

For water you could add oil..ex: cooking oil separates form water because water is heavier than oil.

For Magnesium Sulfate you could add Sodium Carbonate..ex: Sodium Carb reacts to Mg Sulfate adding a darker hue to the liquid and adding a lot of bubbles.

For Sodium Carbonate you could add Sulfuric Acid..ex: Sulfuric Acid would add a reaction to the Sodium Carb that would resembling water boiling

Compounds X and Y are both C6H13Cl compounds formed in the radical chlorination of 3-methylpentane. Both X and Y undergo base-pr

zubka84 [21]

Answer:

Y is a 3-chloro-3-methylpentane.

The structure is shown in the figure attached.

Explanation:

The radical chlorination of 3-methylpentane can lead to a tertiary substituted carbon (Y) and to a secondary one (X).

The E2 elimination mechanism, as shown in the figure, will happen with a simulyaneous attack from the base and elimination of the chlorine. This means that primary and secondary substracts undergo the E2 mechanism faster than tertiary substracts.

Using the diagram below and the labels attached to it answer the following:

MAXImum [283]

Answer & Explanation:

Crest is a point in the cycle where maximum or peak amplitude exists. In another way, it is a point on the positive side of a wave where maximum amplitude exits. Trough is a point in the cycle where minimum amplitude exists.

Crest: points A and E

Trough: points C and J

Wavelength is the distance between two crests or two troughs. One example is distance between points A and E.

Frequency is 3 because there are 3 oscillations in 1 second (follow the line from beginning to point D, then D to G, the G to end).

I asked that question on my brainly account to answer your question so the people that answerd my question said this is right I HOPE IT IS!!

Answer:

See the answer below

Explanation:

1. Organisms produce energy for cells by chemically breaking down and unlocking the energy locked-up within food materials in a process known as cellular respiration. The unlocked energy is then utilized for the cell's metabolic activities.

2. Cellular respiration can be aerobic or anaerobic.

Aerobic respiration involves the breakdown of carbohydrates in the presence of oxygen to yield energy in the form of ATP while carbon dioxide and water are produced as by-products.

$C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP$

Anaerobic respiration involves the breakdown of carbohydrates in the absence of oxygen to produce ATP and lactic acid as a by-product. The lactic acid is later oxidized to carbon dioxide and water to prevent it from building up.

$C_6H_1_2O_6 -> 2C_3H_6O_3 + ATP$

3. Photosynthesis and cellular respiration are both considered metabolic processes that take place in living organisms. However, photosynthesis is peculiar only to green plants and some algae while respiration is common to all living organisms. While photosynthesis is anabolic, that is, it involves the building up of materials; respiration is said to be catabolic because it involves the breaking down of materials.

During photosynthesis, inorganic products are utilized to produce carbohydrates for plants with oxygen gas released as a by-product according to the following equation:

$6CO_2 + 6H_2O --> C_6H_1_2O_6 + 6O_2$

During respiration, the food taken by living organisms is broken down to unlock the energy in it for metabolic activities according to the following equation:

$C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP$
