Explanation:
is the kinetic energy due to the random motion of particles in an object
Answer:
You are correct however there is also potential energy because the energy is released over a period of time.

One step in the industrial production of nitric acid is the reaction of ammonia with oxygen gas. 4NH3(g)+5O2(g)-->4NO(g)+6H2O(g) What is the volume of nitrogen monoxide gas that can be produced from 8L of oxygen gas.
Answer:
Moles of nitrogen monoxide gas produced from 8.0 L of oxygen gas = 6.4 L of nitrogen monoxide gas
Explanation:
Equation of reaction: 4NH₃(g) + 5O₂(g) --> 4NO(g) + 6H₂O(g)
From the equation of reaction, 5 moles of oxygen gas produces 4 moles of nitrogen monoxide gas
1 mole of a gas at STP occupies a volume of 22.4 L
5 moles of oxygen gas occupies a volume of 5 * 22.4 L = 112 L
4 moles of nitrogen monoxide as occupies a volume of 4 * 22.4 L = 89.6 L
Therefore, 89.6 L of nitrogen monoxide gas are produced from 112.0 L of oxygen
Moles of nitrogen monoxide gas produced from 8.0 L of oxygen gas = 8.0 * (89.6/112
Moles of nitrogen monoxide gas produced from 8.0 L of oxygen gas = 6.4 L of nitrogen monoxide gas

How many elements are found in the following chemical equation? K + Cl → KCl
Answer:
2
Explanation:
It's important to remember that elements are
No, unless you're doing some sort of course where they demand that you do. It's useful to remember the general features of the periodic table (what each block is, where they are in relation to each other, roughly where the most common elements are), but memorizing the entire thing would simply be a mnemonic exercise

What does electronegativity measure
the correct electron-dot formula for a molecule of chlorine?
Answer:
Cl has 7 dots
if its Cl2; Cl-Cl it will contain 14 dots
Explanation:
The electron-dot formula of the chlorine molecule Cl₂is shown in the attached diagram below.
What is the lewis electron dot diagram?A lewis electron dot structure is used to represent the number of bonds, the bonding atoms, and the lone pairs left in the atoms in the molecule.
Lines are shown between atoms that are bonded to one another and excess electrons or lone pairs are represented as dot pairs and are placed next to the atoms.
As the valence electrons of each chlorine atom are equal to seven from the electronic configuration of the chlorine atom.
First, the total number of valence electrons in a chlorine molecule is 7 + 7 = 14.
As each chlorine atom needs only one electron to complete its octet. As the octet completes, the rest of the electrons are assigned as the lone pairs of atoms. Therefore, each chlorine atom has three lone pairs of electrons on it.

04. Which two methods can be used to separate a salt from its solution in water?
1 crystallisation
2 decanting
3 distillation
4 filtration
А 1 and 2
B 1 and 3
C 2 and 3
D 3 and 4
Answer:
B 1 and 3
this might be able to help you
Answer:
i think option b
C 1 and 3
Explanation:
Simple distillation is a method for separating the solvent from a solution. For example, water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates.
Crystals grow because salt molecules in the solution meet up and interlock. As they do so, they fit together like puzzle pieces, arranging themselves in a lattice structure, thus creating a crystal nucleus. ... it crystallizes.

1) What is the ground state electron configuration for Oxygen (O)?
2) What is the excited state electron configuration for Oxygen (O)
Help please
Answer:
1)Oxygen atoms have 8 electrons and the shell structure is 2.6. The ground state electron configuration of ground state gaseous neutral oxygen is [He]. 2s2. 2p4 and the term symbol is 3P2.
Explanation:
2)If the element were to become excited, the electron could occupy an infinite number of orbitals. However, in most texts the example will be the next available one. So for oxygen, it might look like this: 1s22s22p33s1 - where the valence electron now occupies the 3s orbital in an excited (i.e. not ground) state

1s^2 , 2s^2 , 2p^3How does the body use energy from respiration
Answer:
Some of the energy released in respiration is used to make larger molecules from smaller ones, to enable muscles to contract and to keep temperature steady. Some of the energy released in respiration in plants is used to make amino acids and proteins. c Food provides the amino acids needed to make body proteins.
Explanation:
You place 12.0 milliliters of water in a graduated cylinder. Then you add 15.0 grams of metal to the water and the new water level is 13.91 milliliters. What is the density of the metal in grams per milliliter?
Answer:
The answer is 7.85 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
volume = final volume of water - initial volume of water
volume = 13.91 - 12 = 1.91 mL
We have
[tex]density = \frac{15}{1.91} \\ = 7.853403141...[/tex]
We have the final answer as
7.85 g/mLHope this helps you
Answer:
Hello, Im Mack :)
Here is the Correct Solution for your question:
Answer is 7.85 g/mL
