In this type of bond, electrons are lost or gained by atoms, and the atoms are held together by electrical attraction.

1 answer:

8 0

<span>In Ionic type of bonding, electrons are lost (more protons than electrons and positive charge) or gained (more electrons than protons, still a negative charge) by atoms, and the atoms are held together by electrical attraction in the process. Covalent bondings are the sharing of electrons as well as partial bondings. Covalent bondings’ electrons have the same charges thus, there is no gaining or losing electrons in the process of sharing. Strong bondings are applicable only to Hydrogen (H) atoms. </span>

A charge partides round a 1 m radius circular particle accelerator at nearly the speed of light. Find : (a) The period (b) The c

Scrat [10]

Explanation:

It is given that,

Radius of circular particle accelerator, r = 1 m

The distance covered by the particle is equal to the circumference of the circular path, d = 2πr

d = 2π × 1 m

(a) The speed of satellite is given by total distance divided by total time taken as :

$speed=\dfrac{distance}{time}$

Let t is the period of the particle.

$t=\dfrac{d}{s}$

d = distance covered

s = speed of particle

It is given that the charged particle is moving nearly with the speed of light

$t=\dfrac{d}{c}$

$t=\dfrac{2\pi\times 1\ m}{3\times 10^8\ m/s}$

$t=2.09\times 10^{-8}\ s$

(b) On the circular path, the centripetal acceleration is given by :

$a=\dfrac{c^2}{r}$

$a=\dfrac{(3\times 10^8\ m/s)^2}{1\ m}$

$a=9\times 10^{16}\ m/s^2$

Hence, this is the required solution.

An 8.5-l tire is filled with 0.55 mol of gas at a temperature of 305 k. what is the pressure of the gas in the tire?

const2013 [10]

Answer:

1.62 atm

Explanation:

We can solve the problem by using the ideal gas equation:

$pV=nRT$

where:

p = ? is the pressure of the gas in the tire

V = 8.5 L is the volume of the tire

n = 0.55 mol is the number of moles of the gas

R = 0.0821 atm L / K mol is the gas constant

T = 305 K is the temperature of the gas

By re-arranging the equation and substituting the numbers in, we find:

$p=\frac{nRT}{V}=\frac{(0.55 mol)(0.0821 Latm/Kmol)(305 K)}{8.5 L}=1.62 atm$

there many things you could do, one is try getting a cooling system, another thing is its extramly hot and you may need to tunr off your car to prevent the engine from over heating.
