How does a solution with a pH of 2 compare to a solution with a pH of 1?

Chemistry
1 answer:
Thepotemich [5.8K]3 years ago
5 0
I’m going to go with The pH 1 solution is two times more acidic than that with a pH of 1. If that’s not the answer, then my second best guess would be The pH solution is ten times more acidic than that with a pH of 2.

The first and third answer choice wouldn’t even be an answer so you can just cancel those two out and pick between answer choice 2 or 4.

Hope this helps, and have an amazing day!! :))

A molecule contains four bonded pairs of electrons and zero lone pairs. What is the name of the molecular geometry?
vagabundo [1.1K]

Answer: Option (d) is the correct answer.

Explanation:

A tetarhedral geometry is the geometry which includes four atoms bonded to the central atom and it does not contain any lone pair of electron.

For example,  CH_{4} has tetrahedral geometry.

Thus, we can conclude that a molecule which contains four bonded pairs of electrons and zero lone pairs. The name of the molecular geometry is tetrahedral.

Propose a mechanism for the following reaction.
raketka [301]
First, recognize that this is an elimination reaction in which hydroxide must leave and a double bond must form in its place. It is likely an E2 reaction. Here is an efficient mechanism:
1) Pre-reaction: Protonate the -OH to make it a good leaving group, water. H2SO4 or any strong H+ donor works. The water is positively charged but still connected to the compound.
2) E2: Use a sterically hindered base, such as tert-butoxide (tButO-) to abstract the hydrogen from the secondary carbon. [You want a sterically hindered base because a strong, non-sterically hindered base could also abstract a hydrogen from one of the two methyl groups on the tertiary carbon, and that leads to unwanted products, which is not efficient]. As the proton of hydrogen is abstracted, water leaves at the same time, creating an intermediate tertiary carbocation, and the 2 electrons in the C-H bond immediately are used to make a double bond towards the partial positive charge.
In the products we see the major product and water, as expected. Even though you have an intermediate, remember that an E2 mechanism technically happens in one step after -OH protonation.

A plant release it’s seed , but soon there after, the area seeds are in experiences a yearlong drought. How would the seeds most
SOVA2 [1]

Answer:

Plants will absorb water through their roots and release water as vapor into the air through these stomata. To survive in drought conditions, plants need to decrease transpiration to limit their water loss. Some plants that live in dry conditions have evolved to have smaller leaves and therefore fewer stomata.

15. When traveling through a smoke-filled area, a person must be able
maxonik [38]

When traveling through a smoke-filled area, a person must be able to have distance of at least 4 feet in order to safely reach a fire exit. That is option C.

<h3>What is a smoke-filled area?</h3>

Smoke-filled area is an enclosed area that is filled with smoke gas that is usually made up of carbon monoxide.

The smoke-filled area is usually caused by

  • Fire out break

  • Burning of plastics or chemical products

  • Release of fuming gases.

When there is smoke-filled area die to fire out break, there are some guidelines to follow to safely reach the fire exit early enough.

The importance of these guidelines include the following:

  • enable rescuers to navigate a scene more quickly,

  • identify risks and hazards,

  • locate safety points,

  • determine the safest way in and out of a building, and

  • map out evacuation routes.

The affected individual should get down and crawl while taking short breath through the nose because cleaner air is nearest to the floor.
