Covalent bonds uses prefixes to indicate the number of atoms in the compound.
And example would be water which is dihydrogen monoxide, which means there are 2 hydrogen molecules and one oxygen molecule. The chemical formula would be H2O.

1.00g of a metallic element reacts completely with 300cm3 of oxygen at 298K and 1 atm pressure to form an oxide which contains O
elena55 [62]

Answer:

The metal is most likely calcium which has a molar mass of 40.078 g

<em>Note: The question is incomplete. The complete question is given below:</em>

1.00g of a metallic element reacts completely with 300cm3 of oxygen at 298K and 1 atm pressure to form an oxide which contains O2– ions. The volume of one mole of gas at this temperature and pressure is 24.0dm3 .

What could be the identity of the metal?

<em>A calcium B magnesium C potassium D sodium</em>

Explanation:

Number of moles of the oxygen gas reacted is first determined:

Volume of oxygen gas = 300 cm³ = 0.30 dm³

1 mole of a gas occupies 24.0 dm³ at this temperature and pressure

Number of moles of oxygen gas that will occupy 0.30 dm³ = 0.3/24 = 0.125 moles

Let M be represent the metallic element. The equation of the reaction will be:

2M + O₂ ----> 2MO

From the equation of reaction;

2 moles of the metal reacts with 1 mole of oxygen gas

2 * 0.125 moles of the metal will react with 300 cm³ of oxygen  = 0.025 moles

Since the mass of the metal that reacted with oxygen is 1.0 g, therefore, 1.0 g of the metal = 0.025 moles

mass of 1 mole of the metal = 1 /0.025 = 40.0 g

Therefore, the metal is most likely calcium which has a molar mass of 40.078 g

NAME the four phases of matter and DESCRIBE how the intermolecular forces and kinetic energy change as you change phases.
weqwewe [10]

Answer: Substances on Earth can exist in one of four phases, but mostly, they exist in one of three: solid, liquid or gas. Learn the six changes of phase: freezing, melting, condensation, vaporization, sublimation and deposition. Intermolecular forces are forces between molecules that determine the physical properties of liquids and solids. 11.2 Vaporization and Vapor Pressure— vaporization is the conversion of a liquid to a gas (vapor), and the quantity of heat associated with this phase change is known as the enthalpy (heat) of vaporization. When kinetic energy is increasing molecules are simply moving faster. However, when the potential energy is increasing molecules are changing phases. Therefore, when the potential energy is increasing is when the molecule is changing phases. Phase changes require either the addition of heat energy (melting, evaporation, and sublimation) or subtraction of heat energy (condensation and freezing). ... Changing the amount of heat energy usually causes a temperature change.

HOpe this helps..... Stay safe and have a Merry Christmas!!!!!!!!!! :D

How can you describe the arrangement of sodium ions and chloride ions?
Blababa [14]
A sodium ion has a charge of +1
A chlorine ion has a charge of -1
These ions are bonded by electrostatic forces, by the principles rule that all opposites attract. So it looks like a one Na atom bonded to one Cl atom. Like a double scoop ice cream that's not stacked
