Predict the organic product formed when phosgene reacts with an excess of methanol.

Answers

Answer 1

Answer: When phosgene is reacted with an excess of methanol, this produces dimethyl carbonate. Dimethyl carbonate is used in methylating anilines, phenols, and carboxylic acids, and is also being studied for its use as an alternative additive in fuel.

The industrial production of dimethyl carbonate no longer uses phosgene because of the latter's toxicity. Phosgene widely gained infamy when it was used in chemical warfare during WWI.

Based on the trend, an electron will be most strongly attracted to Cl, chlorine. The correct option is D.

What is electronegativity?

Electronegativity is a property of an element which show the tendency of that element to accept electrons from other element. When an atom accept electrons, it gets a negative charge, the charge increase with the increase of accepting number of electrons.

Chlorine is a gas and is highly acidic. It has the highest electronegativity because it has the highest tendency to form a covalent bond with other element.

Chlorine has seven electrons in its outer shell, and it needs only one electron to complete its octave equal to the noble gas configuration.

Thus, the correct option is D. Cl.

Answer:

Explanation:

The electronegativity follow the trend that the higher the element is the more electronegative he is, for exemplo, in F, Cl and Br are all from the same group, 17A, put F has the lowest atomic number, followed by Cl and Br is the last, because of that F is the more electronegative from them, followed for Cl and Br is the element with lowest electronegativity.

And this trend also says that the element that are on the right of the table will have the higher electronegativity, for exemplo F, K and Be, all of the will have electron on the second band of valence but F is for the group 17A, K is from the 1A and Be is form the 2A. Because of that F is, one again, the one with the highest electronegativity followed by Be and K is the one with the lowest electronegativity of them all.

What's the balanced equation for cellular respiration?

Answers

Correct answer is:

$C_(6)H_(12)O_6+6O_(2)\Rightarrow 6CO_(2)+6H_(2)O+energy$

But how to get there?

Let's start with simple explanation of what exactly is cellular respiration.

Cellular respiration is a multistage biochemical oxidation process of organic substances when prime product is energy (ATP - adenosine triphosphate) and other are released waste products. Cellular respiration takes place even if other metabolic processes are stopped, but cellular respiration may differ in particular organism groups.Some reactions during whole process of cellular respiration are similar in all types of living organisms.

Cellular respiration is prime indication of declining living processes.Only viruses which are on the edge of living organism and chemical particle are not performing cellular respiration.But to the point :P

In cellular respiration all substrates which are in the cell might be organic, but mostly we are using sugar oxidation - glucose in the presence of oxygen. Chemical formula of sugar looks like this:

$C_(6)H_(12)O_6$

Oxygen is just

$O_2$

so for now we have just part of the equation:

$C_(6)H_(12)O_6+O_(2)\Rightarrow$

But what would be on the right hand side?

It's quite simple, remember equation of full combustion? If we want to burn something we need oxygen like in the equation, so the product of this equation would be carbon dioxide, water and of course energy (ATP).Carbon dioxide formula looks like this:

$CO_(2)$

As a reminder water formula:

$H_(2)O$

Full formula would look like that:

$C_(6)H_(12)O_6+O_(2)\Rightarrow\ CO_(2)+H_(2)O+energy$

But still as you see this equation is unbalanced, after balancing it would like that:

$C_(6)H_(12)O_6+6O_(2)\Rightarrow 6CO_(2)+6H_(2)O+energy$

At the end I would like to explain one more thing. Energy which has been released during this process is part of high-energy connection which might be used to perform chemical reactions in the cell or to move organism for example in muscles. We need to remember that production of ATP is not happening with 100% efficiency and part of this energy is released as heat.

C2H5OH is able to dissociate in water to conduct an electric current. This compound could be classified as

Answers

The fact that when in solution C₂H₅OH conducts electricity means that it is an electrolyte so you can automatically cross out A and C (the definition of an electrolyte is a substance that will conduct electricity when in a solution). I think the correct answer is B due to the -OH group (the - indicates a covalent bond) which allows the molecule to give up a proton (H⁺).
I hope this helps. Let me know if anything is unclear.

Photosynthesis transfers carbonfrom the nonliving environment to the living environment.
from the cell to the air.
from the water to the cell.
from the nucleus to the mitochondria.

Answers

Photosynthesis is the process in plants to make their food. This involves the use carbon dioxide to react with water and make sugar or glucose as the main product and oxygen as a by-product. I think the best answer would be the first statement.

Answer: Option A

Explanation:

Photosynthesis is a process that helps the plants to make food by the help of carbon dioxide from the atmosphere and water, nutrients from soil and converts it into glucose in the presence of sunlight.

Atmosphere is a non living component of environment where carbon dioxide is present and it is transferred to plants which is a living component of ecosystem.
