For a hypothetical reaction the linear Arrhenius equation is LaTeX: y=-15035x+41.45y = − 15035 x + 41.45. What is the activation

Y_Kistochka [10]

Arrhenius equation is LaTeX: y=-15035x+41.45y = − 15035 x + 41.45. What is the activation energy for this reaction is described below.

Explanation:

When the rates are equal and the concentration of reactants and products are constant not equal. Other like activation energies and potential energies are not necessary for equilibrium.

The activation energies of the forward and reverse reactions ,the rates of the forward and reverse reactions are 25 minutes ago.

What is the change in heat energy when 132g of copper at 32.2°C is raised to 45.0oC? The specific heat of copper is 0.385 J/g °C

Rudik [331]

Heat energy can be calculated by using the specific heat of a substance multiplying it to the mass of the sample and the change in temperature. It is expressed as:
<span>
Energy = mCΔT
</span><span>Energy = 132 (0.385) (45 - 32.2)
</span><span>Energy = 650.50 J</span>

Tin has many possible isotopes. Three of these isotopes are 116sn, 120sn, and 126sn. What is the mass number of each? How many p

Aneli [31]

Isotopes are defined as atoms of same element with different mass number and same atomic number.

Here, atomic number is equal to number of protons and number of electrons, it is denoted by symbol Z thus,

$Z=n_{e}=n_{p}$

and, mass number is equal to sum of number of protons and neutrons, it is denoted by symbol A thus,

$A=n_{p}+n_{n}$

The three isotopes of tin are given, Sn-116, Sn-120 and Sn-126, mass number for these three isotopes is 116, 120 and 126 respectively. Since, they are isotopes thus, atomic number remains the same that is 50.

Since, $Z=n_{e}=n_{p}$ thus, number of protons and electrons will be 50.

For Sn-116,

$A=n_{p}+n_{n}$

Or,

$116=50+n_{n}$

Or,

$n_{n}=116-50=66$

For Sn-120,

$n_{n}=120-50=70$

For Sn-126,

$n_{n}=126-50=76$

Therefore, mass number, number of protons, electrons and neutrons in all three isotopes are:

Sn-116:

Mass number= 116

Protons=50

neutrons=66

electrons=50

Sn-120:

Protons=50

neutrons=70

electrons=50

Sn-126:

Protons=50

neutrons=76

electrons=50
