Answer:
Decomposition Reaction
Explanation:
If you are referring to what type of reaction that occurred then the answer would be decomposition reaction.
This is a chemical reaction where one reactant is broken down into two or more products.
REACTANT → PRODUCT
AB → A + B
The products can be two or more elements or two or more compounds, depending on what was decomposed.
Answer: 5.84x10^4
Explanation: You start with (9.00x10^26 atoms)x(1 mol/ 6.022x10^23)x(39.10 g/1 mol)
The grams of ethane present in a sample containing 0.4271 mole is 12.84 g
<h3>Description of mole </h3>
The mole of a substance is related to it's mass and molar mass according to the following equation
Mole = mass / molar mass
With the above formula, we can obtain the mass of ethane. Details below
<h3>How to determine the mass of ethane</h3>
The following data were obtained from the question:
- Mole of ethane = 0.4271 mole
- Molar mass of ethane = 30.067 g/mol
- Mass of ethane =?
The mass of ethane present in the sample can be obtained as follow:
Mole = mass / molar mass
Cross multiply
Mass = mole × molar mass
Mass of ethane = 0.4271 × 30.067
Mass of ethane = 12.84 g

Answer:
A and B
Explanation:
This is because there was emission of gamma (Y) radiations in both the reactions.
1. The name of this element is Carbon because there are 6 electrons in the shell.
2. Sorry I didn't learn that. And I don't know.
1. A metal is a solid substance, usually hard. On the other hand, a non-metals is a solid or gaseous material, in which the metallic properties are absent.
2. When a new substance is formed at that time we can understand that chemical reaction has taken place. It can't be reversed.
4. Neutron = no charge
Electron = negative
Proton= positive
5. Nucleus has a positive charge.
6. An atom is bigger. Because electrons are what takes up space in atoms, the result is that the size of the biggest filled orbital determines the size of the atom or ion.
