6 0

We have that

  • The Element with 49 protons is Indium

the isotope symbol in the one-line format

  • indium -104
  • We have that this is a cation

From the question we are told

An ionic isotope has 49 protons, 50 electrons, and 55 neutrons.

• What is the name of the element?

What is the isotope symbol in the one-line format (e.g., hydrogen-2)?

Is this a cation or is this an anion? Explain how you know.

Generally

Generally an isotope is an a variant form of a element bearing different number of Neutrons but same Proton

Therefore

For an isotope with 49 protons, 50 electrons, and 55 neutrons.

  • The Element with 49 protons is Indium

the isotope symbol in the one-line format

  • indium -104

  • We have that this is a cation

What is the velosity of a 72.3 kg jogger with a kinetic energy of 1080.0 J?
Svet_ta [14]

Answer: 5.47m/s

Explanation:

Mass = 72.3kg

K.E = 1080.0J

V =?

K.E = 1 /2MV^2

V^2 = 2K.E /M = (2x1080)/72.3

V = sqrt [(2x1080)/72.3]

V = 5.47m/s

A sample of oxygen gas is compressed from 30.6 L to 1.8 L at constant temperature pressure of 1.8 atm. Calculate the amount of e
ad-work [718]

Answer:

the change in the internal energy of the system is 3,752.67 J

Explanation:

Given;

initial volume of the gas, V₁ = 30.6 L

final volume of the gas, V₂ = 1.8 L

constant pressure of the gas, P = 1.8 atm

Energy released by the system, Q = 1.5 kJ = 1,500 J

Apply pressure-volume work equation, to determine the work done on the gas;

w = -PΔV

w = -P(V₂ - V₁)

w = - 1.8 atm(1.8 L - 30.6 L)

w = 51.84 L.atm

w = 51.84 L.atm x 101.325 J/L.atm

w = 5,252.67 J

The change in the internal energy of the system is calculated as;

ΔU = Q + w

Since the heat is given out, Q = - 1,500 J

ΔU = -1,500 J  +  5,252.67 J

ΔU = 3,752.67 J

Therefore, the change in the internal energy of the system is 3,752.67 J
