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

Answers

Answer 1

Answer: 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.

Which of the following is a major consequence of the shifting of the Intertropical Convergence Zone (ITCZ)? A. monsoon rains in South Asia B. few winds in the horse latitudes C. jet streams over the North Atlantic D. lush vegetation in the Amazonian rainforest

Answers

The shifting of the Intertropical Convergence Zone (ITCZ) results to A. monsoon rains in South Asia. The ITCZ is a region on Earth where the Northern and Southern hemispheres meet, causing the trade winds from both regions to meet. This causes a belt of low pressure, making the region prone to heavy rainfall or monsoon rains.

In any pure sample of CO2, the ratio of the mass of carbon to the mass ofoxygen is always the same. You can justify this ratio by the fact that
compounds are composed of which of the following?
A. Identical molecules created from atoms combined in whole

B. Atoms whose chemical properties do not change during a
chemical reaction
O C. Atoms whose masses do not change during a chemical reaction
D. Different molecules which together produce the observed
elemental ratios

Answers

Identical molecules created from atoms combined in whole number ratios this is the best justification for In any pure sample of CO2, the ratio of the mass of carbon to the mass of oxygen is always the same.

What ratio of Mass of Oxygen and Carbon?

Consider the elements carbon and oxygen. Combined in one way, they form the familiar compound carbon dioxide. In every sample of carbon dioxide, there are 32.0g of oxygen present for every 12.0g of carbon. By dividing 32.0 by 12.0, this simplifies to a mass ratio of oxygen to carbon of 2.66 to 1.
Carbon has an atomic weight of 12, oxygen in diatomic form(O2) of 32 and CO2 of 44. This means that the mass of 6x1023 atoms of CARBON has a mass of 6 kilograms, the mass of 6x1023 diatomic oxygen molecules is 32 kg, and for CO2 it is 44kg. So carbon is the lightest and CO2 the heaviest.

Exactly 1/16 of a given amount of protactinium-234 remains after 26.76 hours. What is the half life of protactinium-234?

Answers

This is a problem involving half-lives. We can solve this problem by using the equation as shown: A=Aoe^-(ln2/t)T where A is the final amount (1gram *assumed), Ao is the initial amount (16g *assumed), t is the half-life *required) and lastly T time elapsed (26.76h). Plug in the values in the equation and you should get 6.69 hours.

the reaction below shows how silver chloride can be synthesized. agno3 nacl nano3 agcl how many moles of silver chloride are produced from 15.0 mol of silver nitrate?

Answers

The balanced chemical reaction is:

AgNO3 + NaCl = AgCl + NaNO3

We are given the amount of silver nitrate to be used for the reaction. This will be the starting point of our calculations.

15.0 mol AgNO3 ( 1 mol AgCl / 1 mol AgNO3 ) = 15.0 mol AgCl
