Which statement is true concerning the reaction N(g) + N(g) → N2(g) + energy? A bond is broken and energy is absorbed.
A bond is broken and energy is released.
A bond is formed and energy is absorbed.
A bond is formed and energy is released.

Answers

Answer 1

Answer:

Answer:

A bond is formed and energy is released.

Explanation:

Given a reaction equation, the elements which we have on the left side of the arrow are called the reactants and the elements which we have on the right side are called the products.

In this exercise, the reactants are N(g) and N(g) and the products N2(g) and energy.

After the reaction took place, N(g) and N(g) disappeared and instead N2(g) was formed. We can conclude that a bond was formed between both N(g).

Also, in the products certain amount of energy was released (because we have it on the products side)

The correct option is ''A bond is formed and energy is released''

What is special about nitrogen?
and what is it main function?

Answers

Nitrogen is present in many spheres of the Earth, including the atmosphere and biosphere. Nitrogen makes up around 80% of the atmosphere (more than oxygen), and exists as a diatomic molecule. it's also essential in the function of plants, as the most commonly used mineral nutrient. It is also used in photosynthesis and is a major component of amino acids which make protein.

Which element has the following mass spectrum?

Will mark as Brainliest✅

Answers

Cf, the element has the following mass spectrum. Therefore, option (D) is correct.

California (Cf) is a radioactive element with a complicated mass spectrum that shows its isotopic makeup and decay trends. Peaks in Cf's mass spectrum denote isotopes with differing mass-to-charge ratios. These peaks signify isotopes, which are elemental atoms with varying neutron counts.

The mass spectrum yields important information about the sample's isotope abundance and masses. Researchers can determine Cf's isotopic distribution and nuclear characteristics like decay modes and half-lives by analyzing peaks and intensities. This is crucial since Cf's radioactivity and prospective uses in nuclear research and medicine are vital.

In conclusion, Californium's massspectrum reveals its isotopic makeup and behavior, helping researchers understand its characteristics and uses. Therefore, option (D) is correct.

Explain how engineers and scientists may work together to produce a protein in the lab.

Answers

Scientists would deal with the aspect of cloning a particular gene into a bacterium or making of hybridoma cells that will produce the particular required protein. Engineers will then design and develop a bioreactor which is a programmed instrument that avails the required substances to the cells/bacteria in specific amounts and at particular time periods to grow and reproduce the cells in large amounts.

the scientists would do biological studies of how the protein breakdown and combines with the muscles the engineers with then create a delivery system to get the protein to the muscle quicker and more effectively

Elements that are characterized by the filling of p orbitals are classified as _____.a. Groups 3A through 8A
b. transition metals
c. inner transition metals
d. groups 1A and 2A

Answers

Answer : The correct option is, (a) Groups 3A through 8A

Explanation :

The general electronic configurations of :

Group 1A : $ns^1$

Group 2A : $ns^2$

Group 3A : $ns^2np^1$

Group 4A : $ns^2np^2$

Group 5A : $ns^2np^3$

Group 6A : $ns^2np^4$

Group 7A : $ns^2np^5$

Group 8A : $ns^2np^6$

Transition metal : $(n-1)d^((1-10))ns^((0-2))$

Inner transition metal (Lanthanoids) : $4f^((1-14))5d^((0-1))6s^2$

Inner transition metal (Actinoids) : $5f^((0-14))6d^((0-1))7s^2$

From the general electronic configurations, we conclude that the groups 3A through groups 8A elements that are characterized by the filling of p-orbitals.

Elements that are characterized by the filling of p orbitals are classified as $\boxed{{\text{a}}{\text{. Groups 3A through 8A}}}$ .

Further Explanation:

In order to make the study of numerous elements easier, these elements are arranged in a tabular form in increasing order of their atomic numbers. Such a tabular representation of elements is called a periodic table. Horizontal rows are called periods and vertical columns are called groups. A periodic table has 18 groups and 7 periods.

a. Groups 3A through 8A

The elements from group 3A to 8A has the general outermost electronic configuration of $n{s^2}n{p^(1 - 6)}$ . So the added electrons are to be filled in p orbitals.

b. Transition metals

These metals have the general valence configuration of $\left( {n - 1} \right){d^(1 - 10)}n{s^(0 - 2)}$ . This indicates that the added electrons enter either s or d orbitals.

c. Inner transition metals

These are classified as lanthanoids and actinoids. The general outermost configuration of lanthanoids is $4{f^(1 - 14)}5{d^(0 - 1)}6{s^2}$ while that of actinoids is $5{f^(0 - 14)}6{d^(0 - 1)}7{s^2}$ . In both cases, the added electron enters either d or f orbitals.

d. Groups 1A and 2A

The elements of group 1A have the general valence electronic configuration of $n{s^1}$ . It implies the last or valence electron enters in the s orbital. The group 2A elements have a general configuration of $n{s^2}$ . Here also the last electron enters the s orbital.

So elements from groups 3A to 8A are classified by the filling of p orbitals and therefore option a is correct.
