What are three units you can measure moler mass in

liraira [26]

By looking at a periodic table, we can conclude that the molar mass of lithium is 6.94g, the molar mass of zinc is 65.38g, and the molar mass of gold is 196.97g. Each of these quantities contains 6.02×1023 atoms of that particular element. The units for molar mass are grams per mole, or g/mol.

So The answers are Lithium, Gold, Zinc

How does the equilibrium change to counter the removal of A in this reaction? A + B ⇌ AB The equilibrium . Simultaneously, there

kykrilka [37]

Based on Le Chatelier's principle, if the equilibrium of a system is disturbed by changing the temperature, pressure or concentration, then it will shift in a direction to undo the effect of the induced change.

The given equilibrium is:

A + B ↔ AB

Removal of the reactant A implies that the concentration of A has decreased, therefore the equilibrium will shift in a direction to produce more of A. Thus, it will shift to the left and the rate of the reverse or backward reaction will increase.

18. Use the activity series to predict whether the following synthesis reaction will occur. Write the chemical equations for the

MAXImum [283]

Answer: The chemical reaction for the synthesis reaction is given below.

Explanation:

Synthesis reaction is defined as a chemical reaction in which two small chemical substances combine together to form a single compound. The general equation for this chemical reaction follows:

$A+B\rightarrow AB$

For the reaction of calcium and oxygen combining together to form calcium oxide, the equation follows:

$2Ca(s)+O_2(g)\rightarrow 2CaO(s)$

By Stoichiometry,

2 moles of calcium element combines together with 1 mole of oxygen gas to produce 2 moles of calcium oxide.

Hence, the chemical equation for the reaction is given above.

Three carbon atoms are linked by single covalent bonds such that they form the shape of a V. All of the unshared electrons form

Nostrana [21]

Answer:

C) 8

Explanation:

Total number of carbon atoms = 3

Number of single bonds = 3

So, each carbon is bonded to the next carbon with the single bond, Number of unshared electrons left with the terminate carbons are 3 and with the intermediate carbon is 2.

Thus, the two terminate carbon have 3 hydrogen each and the intermediate will have 2.

Total - 8

Graph of the relationship between mass and thermal energy

elixir [45]

Thermal energy is the sum of the kinetic and potential energies of all the particles in an object.

Assume that you have 250 gL of water and 1 kg of water at the same temperature.

Then, each water molecule has the same kinetic energy.

The larger sample contains four times as many molecules, so it contains four times as much thermal energy.

Thus, thermal energy is directly proportional to mass.

In symbols, KE ∝ m or KE = km.

The graph of a direct proportion is a straight line passing trough the origin.

It should look something like the graph below.
