Answer: 0.613 moles

Explanation: To convert from grams to moles, you have to use the molar mass provides on the periodic table. The molar mass of lead is 207.2 g/mol. To find the moles, we need to divide the grams of lead by the molar mass. 127/207.2 is equal to about 0.613 moles.

Nitrogen and hydrogen combine at a high temperature, in the presence of a catalyst, to produce ammonia. N2(g)+3H2(g)⟶2NH3(g) Ass

yaroslaw [1]

Answer:

moles of ammonia produced = 0.28 moles

Explanation:

The reaction is

$N_{2}(g)+3H_{2}(g) --> 2NH_{3}(g)$

As per equation, one mole of nitrogen will react with three moles of hydrogen to give two moles of ammonia

So 0.140 moles of nitrogen will react with = 3 X 0.140 moles of Hydrogen

= 0.42 moles of hydrogen molecule.

this will give 2 X 0.140 moles of ammonia = 0.28 moles of ammonia

the moles of ammonia produced = 0.28 moles

Here the nitrogen is limiting reagent.

Explanation:

Any substance that is able to neutralize acidity in the stomach is generally known as an antacid. There are various kinds of antacids that are in common use. It should be noted that the stomach is usually slightly acidic.

Milk of magnesia is the substance magnesium hydroxide with chemical formula Mg(OH)2. A solution of milk of magnesia contains Mg^2+ and OH^-.

Hence the negative ion contained in milk of magnesia is the hydroxide ion OH^-.

Why do the particles of objects have both kinetic and potential energy?

OLEGan [10]

The particles of objects have both kinetic and potential energy because these forces are drive by the force of motion or stillness of an object. Potential energy is the a type of energy which an object possess however without motion. Kinetic energy in the other hand, is the energy in motion or if the object moves along from one space to another with respect to time. They both have these two energies by the presence of atoms in these entities.

If you were going to graphically determine the enthalpy of vaporization, δhvap, for this liquid, what points would you plot

Klio2033 [76]

It depends on what type of graph you have. The easiest would be using a H-T diagram. Enthalpy of vaporization is the physical change from liquid to vapor. It occurs at a constant pressure and a constant temperature. As shown in the picture, 1 point is drawn on the subcooled liquid, and another point of the saturated vapor isothermal line. Now, the difference between those two points is the value for the enthalpy of vaporization of water.
