Answer:
Chlorine
Explanation:
The tendency of an atom to attract electron is referred to as electronegativty. In the periodic table, electronegativity increases across the period from left to right and decreases down the group.
Following that trend, the element with the greatest electronegativty is;
Chlorine
The atom that has the strongest attraction for electrons in a chemical bond in the options is Chlorine.
The tendency of an atom to attract electrons to itself is know as electronegativity.
The most electronegative element is fluorine.
Electronegativity increases across the period in the periodic table.
Electronegativity decreases down the group in the periodic table.
Examples of electronegative elements are mostly non metals like oxygen, fluorine, chlorine, etc.
Therefore, the atom that has the strongest attraction for electrons in a chemical bond is Chlorine.

What volume of chlorine gas (Cl2), measured at STP, can be produced by the decomposition of 73.0g of hydrogen chloride gas (HCl), according to the balanced equation? (the other product is hydrogen gas (H2))
Answer:
Explanation:
2HCl = H₂ + Cl₂
2 mole 1 mole 1 mole
73 gram HCl = 73 / 36.5 = 2 mole of HCl
2 moles of HCl will produce 1 mole of chlorine gas .
At STP , one mole of chlorine gas has volume equal to 22.4 litre .

what does solubility mean?
Solubility means the ability of a solute to dissolve in solvent to form a solution.
What is solubility?Solubility is defined as the maximum amount of a substance that will dissolve in a given amount of solvent at a particular temperature.
The solute can be a solid, liquid or a gas.
The solubility of a solid or a liquid solute in a solvent is affected by the temperature, while the solubility of a gaseous solute is affected by both the temperature and the pressure of the gas.
Therefore, Solubility means the ability of a solute to dissolve in solvent to form a solution.

Where are fusion reactions found
Answer:
In a nuclear fusion reaction, the nuclei of two atoms combine to create a new atom. Most commonly, in the core of a star, two hydrogen atoms fuse to become a helium atom. Although nuclear fusion reactions require a lot of energy to get started, once they are going they produce enormous amounts of energy.

what is a flame,metion two types of flames
Answer:
A flame is defined as the gaseous part of the fire which is visible to us. A flame is created due to the high exothermic reaction.
Two types of flames based on the amount of oxygen available are:
Non-luminous or blue flame: In this type of flame the amount of oxygen is sufficiently large and it gives blue flame. For example: flame of Gas stove. Luminous flame: In this type of flame, the oxygen availability id not sufficient for the complete combustion and left unburnt carbon particles that forms yellow light flame. For example: kerosene lamp.How are you able to light a bunsen burner
