What particle is needed to complete the following equation?
14/7N + ____ ---> 14/6C + 1/1H

Answers

Answer 1
Answer:

Explanation:

The given reaction equation is as follows.

      ^(14)_(7)N + ___ \rightarrow ^(14)_(6)C + ^(1)_(1)H

As there is release of one hydrogen which shows that mass number has increase by 1 on the product side.

Therefore, particle ^(1)_(0)n must be added in order to balance the given reaction equation.

Hence, the complete reaction equation will be as follows.

      ^(14)_(7)N + ^(1)_(0)n \rightarrow ^(14)_(6)C + ^(1)_(1)H
Answer 2
Answer:

Final answer:

To complete the nuclear reaction equation, the particle required is a neutron (1/0n). It's calculated based on the law of conservation of mass and atomic numbers in nuclear reactions.

Explanation:

To complete the nuclear reaction equation 14/7N + ____ ---> 14/6C + 1/1H, we need to conserve both the mass number (the sum of protons and neutrons) and atomic number (number of protons). On the left side of the equation, we have nitrogen (represented by 14/7N), with a mass number of 14 and atomic number of 7. On the right side, Carbon (14/6C) has atomic number 6 and a mass number of 14 and Hydrogen (1/1H) has atomic number 1 and a mass number of 1. So, to balance the equation we need an element with atomic number (7-6-1) = 0 and mass number (14-14-1) = -1. This element is a neutron (represented as 1/0n), as it has a mass number of 1 and atomic number of 0.

Which molecule has a nonpolar covalent bond?

Answers

Nonpolar covalent bonds are chemical bonds where two atoms share a pair of electrons with each other and the electronegativities of the two atoms are equal. An example is methane. It has four carbon-hydrogen single covalent bonds. These bonds are nonpolar because the electrons are shared equally.

Final answer:

Nonpolar covalent bonds form when two atoms of the same element or different elements share electrons equally, resulting in a balanced charge distribution. Examples include Methane (CH4) and molecular oxygen (O2). Another case is the CO2 molecule, which is nonpolar because its polar bond moments cancel out.

Explanation:

This leads to a balanced distribution of charges in the molecule, making it nonpolar. Methane, for instance, consists of a carbon atom that shares four electrons equally with four hydrogen atoms, resulting in a bond where the difference in electronegativity between the carbon and hydrogen atoms is minimal.

Another case is CO₂ where the molecule, though consisting of polar bonds, is overall nonpolar because the geometric layout of the molecule allows for the bond moments to cancel each other out, hence no region of the molecule is more positive or negative than any other. Considering the geometry of the molecule is essential when determining the polarity of a molecule with more than one bond.

The density of an object is defined as mass per unit volume. Mathematically we write that: D = M/V. Rearrange this expression for: (a) M = ? (b) V = ?

Answers

The density of an object is defined as mass per unit volume. This can be rearranged to determine the mass or the volume of an object. For mass, the expression of density is rearranged to: M = VD. For the volume, the density is rearranged to: V = D/M.
