Potassium chlorate is a mean little chemical. It likes to decompose rather violently, and when it does, it decomposes into two d

ifferent products--potasssium chloride and a gas. What is this gas produced in the reaction?

Answer:

Oxygen gas

Explanation:

Potassium chlorate KClO3 decomposes thermally to form potassium chloride KCl and oxygen gas is given off. This is in the presence of a catalyst, manganese iv oxide.

Hence, what is being said in essence is that when potassium chloride is heated in the presence of manganese iv oxide catalyst, oxygen is given off as the gaseous product with the formation of potassium chloride.

The chemical equation for the reaction is :

2KClO3 ——-> 2KCl + 3O2

This procedure is one of most important ways through which oxygen can be produced in the laboratory and can be used as a source of oxygen is industrial processes if on a large scale

What orbital is represented by the transition metals in period four
andreev551 [17]

The name transition metal refers to the position in the periodic table of elements. The transition elements represent the successive addition of electrons to the d atomic orbitals of the atoms. In this way, the transition metals represent the transition between group 2 (2A) elements and group 13 (3A) elements.

What is the electron structure of a sodium atom?
Irina-Kira [14]

Answer:

1s2 2s2 2p6 3s1

Explanation:

All the elements in the periodic table, has an atomic number. This number tell us different things, such as number of protons, position in the periodic table among others.

One of the things that tell us the atomic number is the electron structure.

First, all elements begins always with 1s. This is because the first number indicates number of energy level which is in. This tell us, the period of the periodic table is the element, the s, is the type of orbital which the electrons are located. the s orbytal can only have 2 electrons max, and with the increasement of the atomic number, this electrons also increase.

Therefore for an element like Helium, (atomic number = 2) means that we have to begin with the 1s and put 2 electrons, to complete the atomic number. In this case, it would be 1s2.

When we surpass this number, we use another energy level, in this case, 2, and begin again with orbytal s. Then, when we surpass 2s2, we use now another orbytal, which is p. This is because we have more elements in the second period of the table, so we need another kind of energy levels to carry all the electrons. orbytal p can carry up to 6 electrons max, so for an element like Florine (Atomic number = 9), it's structure would be 1s2 2s2 2p5. As you can count the electrons, we have 2 + 2 + 5 = 9, we complete the atomic numbers and the electrons would be, the numbers of electrons located in the last energy level, in this case, the 2s and 2p, and it would be 7 electrons.

Now after this explanation, in the case of sodium (Na), the atomic number of sodium is 11, therefore, we need to count til 11 so:

[Na] = 1s2 2s2 2p6 3s1

As you can see, sodium is the first element of period 3 of the table, and we begin with the energy level 3. In your case it would be the last option you put.

Answer: Wind current

Explanation:

The wind current is the main driving force along with the water currents when one reaches to the seashore. The wind currents above surface of water generates due to the evaporation of water.

The strong wind currents can pull any animal or human walking or running near the sea shore. These currents bring the animal or human towards the sea.
