Answer:Li2O

Explanation:  Lithium is an alkali metal in Group 1.  It has a single valence electron that it would be pleased to give up, or share, with another element.  Oxygen is in Group 16, just one removed from the halogens.  It has 6 valence electrons, and wants 2 mosr to complete it's valence shell.  One lithium will contribute 1 electron, so oxh=ygen will keep looking for a second.  If another lithium is available, it will react with that one also, resulting in Li2O.

If the mass of the products measured 120g what would the mass of the reactants
Ket [755]
It has to be 120g because each and every chemical equation has to satisfy the law of conservation of mass, ie sum of mass of products is always equal to the sum of masses of reactants. If reactants=120g, then products=120g

<em>Answer:</em>

  • At 60 centigrade, the kinetic energy of the substance will be greatest.

<em>Explanation:</em>

As we know, the kinetic energy of substance is directly proportional to Temperature.

The total Kinetic energy can be calculated as follow

                                                K.E = 3/2 n.R.T

From the equations, it is cleared that Temperature is directly proportional to temperature.

What does the difference in potential energy between the reactants and products represent? A. It represents the energy required
Scrat [10]

Answer:

B. It represents the change in enthalpy for the reaction.

Explanation:

The potential energy diagram for a chemical reaction shows its potential energy plotted against the reaction progress coordinate. The potential energy diagram shows how the potential energy of reactants and products vary as reactants are converted into products.

The potential energy of the system refers to energy stored in the chemical bonds of reactants and products. The difference between the potential energy of reactants and products is known as the enthalpy of reaction. This difference in potential energy may be positive or negative. A positive difference in potential energy implies an endothermic reaction while a negative difference in potential energy implies an exothermic reaction.
