Consider each of the following molecules in turn: (a) dimethyl ether, (CH3)2O; (b) trimethylamine, (CH3)3N; (c) trimethylboron,

(CH3)3B; and (d) carbon dioxide (CO2). Describe the hybridization state of the central atom (i.e., O, N, B, or C) of each molecule, tell what bond angles you would expect at the central atom, and state whether the molecule would have a dipole moment.

Suppose you have a sample of table salt (NaCl) that has a mass of 100.0 grams. If
IgorC [24]

Taking into account the definition of molarity, the concentration of the solution is 0.855 \frac{moles}{liter}.

<h3>Definition of molarity</h3>

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

Molarity=\frac{number of moles}{volume}

Molarity is expressed in units \frac{moles}{liter}.

<h3>Molarity of NaCl</h3>

In this case, you have:

  • number of moles of NaCl= 100 grams\frac{1 mole}{58.45 grams} =1.71 moles (being 58.45 g/mole the molar mass of NaCl)
  • volume 2 L

Replacing in the definition of molarity:

Molarity=\frac{1.71 moles}{2 L}

Solving:

Molarity= 0.855 \frac{moles}{liter}

Finally, the concentration of the solution is 0.855 \frac{moles}{liter}.

Substances that have a define size and shape and vibrating particles that are close together are​
Mazyrski [523]

Substances that have a define size and shape and vibrating particles that are close together are called Solid.

Explanation:

There are three states of matter - solid, liquid and gas.

Lets talk about solid state in detail.

In solid particles are closely packed and so they have very less or no space to move which results in vibrating particles. This results in solid substances having a fixed shape and volume.

The particles have very little space in between them, so it is not easy to compress solid.

There is no free space for particles to slide over each other, which does not allow solids to flow.

Also, particles in solid have a regular arrangement, they are not randomly packed.

How many moles of neon gas are there 25.0 L of gas or 5.0°C with a pressure of 89.9 KPa?
vladimir2022 [97]
  • Volume=25L
  • Temperature=5°C
  • Pressure=89.9kPa

Now

\\ \rm\rightarrowtail PV=nRT

\\ \rm\rightarrowtail n=\dfrac{PV}{RT}

\\ \rm\rightarrowtail n=\dfrac{89.9(25)}{5R}

\\ \rm\rightarrowtail n=89.9(5)/R

\\ \rm\rightarrowtail n=449.5/R mol

A small motor does 4000 J of work in 20 s. What is the power of the motor in watts?
TEA [102]

Answer:

200 W

Explanation:

Formula of Power is

P= W/T

where

W= Work and T= Time

so

4000/20 = 200J/s or 200 W
