Answer:
338.38 K
Explanation:
Applying,
PV = nRT............... Equation 1
Where P = pressure, V = Volume, R = Temperature, n = number of moles, T = temperature.
Make T the subject of the equation,
T = PV/nR............. Equation 2
From the question,
Given: P = 1.95 atm, V = 12.3 L, n = 0.854 moles
Constant: R = 0.083 L.atm/K.mol
Substitute these values into equation 2
T = (1.95×12.3)/(0.854×0.083)
T = 338.38 K
Answer:
You meant binary compounds ryt?
Then,
Binary compounds are chemical compounds comprising of two distinct elements
A double covalent bond.
<h3>Explanation</h3>
As their name suggest, ionic bonds are forces between ions of opposite charges. Ionic bonds involve the transfer of electrons from one atom to another. Such transfer can't occur between two carbon atoms. They belong to the same element and have the same tendency to gain or lose electrons. As a result, the bond between them cannot be ionic.
Ion dipole is a force <em>between</em> an ion and a molecule. The bond between the two carbon atoms is located <em>within</em> an organic molecule. The force between the two carbon atoms can't be ion dipole, either.
There are four valence electrons in each carbon atom. Each of them needs four more electrons to achieve an octet. They would achieve that octet by sharing four electrons with other atoms. Each shared electron pair acts as a covalent bond. Each hydrogen atom demands one more electron and would share only one electron with the carbon atom. The first carbon atom in this question shared two electrons with two hydrogen atoms. It needs to share two more with the other carbon atom so that it could achieve an octet. As a result, it would share two pairs of electrons, which will make a double covalent bond between the two carbon atoms.
Phosphorus has 5 valence electrons
Answer:
A nuclear reaction releases more energy per gram and appears to violate the law of conservation of mass.
Explanation:
- In nuclear reactions there arises a shift in the nucleus of the atom. This results in the production of a different element altogether. While in chemical reactions the electrons are rearrangement and there is no change in the nucleus.
- Factors like temperature, pressure, and catalysts do not affect the rate of nuclear reactions while they influence the chemical reactions.
- The change in the energy is higher in nuclear reactions. It arises out of the destruction of mass.
