Answer:I feel the object will continue moving north

Explanation Well in this example an object is moving north at a constant velocity so it has no acceleration, just uniform velocity.

Now if a force of 5N pushes the object eastwards while another force counter acts this force by pushing the object with a force of 5N from the west as well.

So, the object continues moving north as both forces counter act each other which is in a common man's language as both of them sorta neutralize each other effect in a very very informal definition

Which orbital that would never exist in the quantum description of an atom is _____.

Anton [14]

Answer:

C. 2s

Explanation:

the "s" orbital is only possible at an energy level of n = 1. 2s means the energy level is at n = 2 and that's not possible for the "s" sublevel.

Rank the following elements in order of decreasing atomic radius.

Vladimir79 [104]

Answer:

I > Br > Cl > F

Explanation:

Bromide (Br), Fluorine (F), Chlorine (Cl) and Iodine (I) are halogens and they are in the same group of the periodic table. We know that as we go down in the group the atomic radius will increase. The decreasing order of the atomic radius will be:

I > Br > Cl > F

All molecules are compounds<br> True or false

Harrizon [31]

False (All compounds are molecules, but not all molecules are compounds. That is because a molecule can be made up of two atoms of the same kind, as when two oxygen atoms bind together to make an oxygen molecule. However, all compounds are made up of two or more different types of atoms.)

Q 16.1: Select the first step in the Wittig reaction. A : The alkyltriphenylphosphonium halide is deprotonated by a base to make

Dennis_Churaev [7]

Answer:

The phosphorus ylide reacts with the aldehyde or ketone to make an oxaphosphetane.

Explanation:

The Wittig reaction is a reaction that occurs between a phosphorus ylide and an aldehyde or ketone. The final products are an alkene and triphenyl phosphine oxide.

The first step in the reaction is the attack of the phosphorus ylide on the aldehyde or ketone. This is followed by attack of oxygen on phosphorus to form a [2+2] cycloaddition product (oxaphosphetane) which decomposes to form the alkene and triphenylphosphine oxide.

why is a graduated cylinder most appropriate for measuring the volume of a liquid instead of a beaker ?

katovenus [111]

Answer:

Graduated cylinders are designed for accurate measurements of liquids with a much smaller error than beakers. They are thinner than a beaker, have many more graduation marks, and are designed to be within 0.5-1% error. ... Therefore, this more precise relative of the beaker is just as critical to almost every laboratory.

Explanation:

hope this helped!
