The gas law for an ideal gas at absolute temperature T (in kelvins), pressure P (in atmospheres), and volume V (in liters) is PV

allsm [11]

Answer:

The rate of change of the temperature is 0.0365 Kelvin per minute.

Explanation:

Step 1: Given data

ideal gas law: P*V = n*R*T

with P= pressure of the gas ( in atm) = 9.0 atm

with V= volume of the gass (in L) =12L

with n = number of moles = 10 moles

R = gas constant = 0.0821 L*atm* K^−1*mo^−1

T = temperature = TO BE DETERMINED

The volume decreases with a rate of 0.17L/min = dV/dT = -0.17

The pressure increases at a rate of 0.13atm/min = dP/dT

Step 2: The ideal gas law

P * [dV/dT] + V * [dP/dT] = nR * dT/dt

9 atm * (-0.17L/min) + 12L * 0.13atm/min = 10 moles * 0.0821 L*atm* K^−1*mo^−1 *dT/dt

0.03 = 0.821 * dT/dt

dT/dt = 0.03/0.821

dT/dt = 0.0365

Since the gas constant is expressed in Kelvin and not in °C, this means that the rate of chagnge of the temperature is 0.0365 Kelvin per 1 minute.

Give the nuclear symbol for the isotope of gallium, ga, that contains 40 neutrons per atom. Replace the question marks with the

Cerrena [4.2K]

The nuclear symbol of an element have three parts namely:

the symbol of an element
mass number of the element
atomic number of the element

The general representation is as:

$_{Z}^{A}X$

where X is the chemical symbol of the element, A is mass number of the element that is total number of neutrons and protons in the nucleus of an atom, and Z is atomic number of the element that is number of protons in the atom.

Element = Gallium, $Ga$ (given)

Number of neutrons = 40 (given)

Let the nuclear symbol be $_{?}^{?}Ga$ . So, we need to determine the values of "?" in the symbol.

Atomic number of Gallium, $Ga$ = 31

Since, atomic number = Number of protons.

So, number of protons of Gallium, $Ga$ = 31

Mass number = number of protons + number of neutrons

Substituting the values:

Mass number = $31+40 = 71$

So, the nuclear symbol is $_{31}^{71}Ga$ .
