A certain metal M crystallizes in a lattice described by a body-centered cubic (bcc) unit cell. The lattice constant (a, the edg

Furkat [3]

Answer:

radius = 156 pm

Explanation:

The relation between radius and edge length of unit cell of BCC is

r=a $\sqrt{3}$ /4

Given

a = 360 pm

Therefore

r = r = radius = 360 $\sqrt{3}$ /4= 155.88 pm

Or

156 pm

If you can answer as many of these as possible that would be great, will give thanks, 5 stars, and brainliest :)

Answer:

The nucleus of the atom as suggested by "nuclear" chemistry.
Radioactive element are generally very large due to both their high number of protons, neutrons, and electrons.
An excessive amount of protons or neutrons.
Periodic table, table O, and table N.
Personal opinion question.
The atomic number.
It represents the number of protons, and can also represent the number of electrons in a neutral atom (an atom with no charge).
Protons ---- element.
Random, self-generated.
Gamma radiation is the only thing on table O that is mass less. Close to being the same is Beta particles which have almost no mass.
Neutrons and Gamma radiation.
Gamma radiation.
Electrons and Beta particles.
To turn one element into the isotope of another. Yes, I believe it is aptly named because you are changing the identity of the element.
The number of protons because they are what define the identity of an element.

Goodluck!

Consider the single‑step, bimolecular reaction. CH3Br+NaOH⟶CH3OH+NaBr When the concentrations of CH3Br and NaOH are both 0.120 M

GarryVolchara [31]

Answer:

Explanation:

CH₃Br+NaOH⟶CH₃OH+NaBr

It is a single step bimolecular reaction so order of reaction is 2 , one for CH₃Br and one for NaOH .

rate of reaction = k x [CH₃Br] [ NaOH]

.008 = k x .12 x .12

k = .55555

when concentration of CH₃Br is doubled

rate of reaction = .555555 x [.24] [ .12 ]

= .016 M/s

when concentration of NaOH is halved

rate of reaction = .555555 x [.12] [ .06 ]

= .004 M/s

when concentration of both CH₃Br and Na OH is made 5 times

rate of reaction = .555555 x .6 x .6

= 0.2 M/s
