1. The limiting reactant in the reaction is NH₃

2. The mass of the excess reactant remaining is 0.49 g

3. The mass of NO produced from the reaction is 3.35 g

4NH₃ + 5O₂ —> 4NO + 6H₂O

Molar mass of NH₃ = 14 + (3×1) = 17 g/mol

Mass of NH₃ from the balanced equation = 4 × 17 = 68 g

Molar mass of O₂ = 16 × 2 = 32 g/mol

Mass of O₂ from the balanced = 5 × 32 = 160 g

Molar mass of NO = 14 + 16 = 30 g/mol

Mass of NO from the balanced equation = 4 × 30 = 120 g

SUMMARY

From the balanced equation above,

68 g of NH₃ reacted with 160 g of O₂ to produce 120 g of NO

From the balanced equation above,

68 g of NH₃ reacted with 160 g of O₂

Therefore,

1.90 g of NH₃ will react with = (1.90 × 160) / 68 = 4.47 g of O₂

From the calculation made above, we can see that only 4.47 g out of 4.96 g of O₂ given is needed to react completely with 1.90 g of NH₃.

Therefore, NH₃ is the limiting reactant.

Mass of excess reactant (O₂) remaining = 4.96 – 4.47

Mass of excess reactant (O₂) remaining = 0.49 g

In this case, the limiting reactant (NH₃) will be used.

From the balanced equation above,

68 g of NH₃ reacted to produce 120 g of NO

Therefore,

1.90 g of NH₃ will react to produce = (1.90 × 120) / 68 = 3.35 g of NO.

Thus, 3.35 g of NO were obtained from the reaction.

There don't seem to be any H atoms in that formula. All I see is Hg, which is mercury.

An example would be oil. Oil is considered to be hydrophobic (which translates to "fear of water" so it is repelled by water). It floats on the top of water, which is why oil spills result in black blobs that float on the surface of the ocean rather than mix underneath the surface.

Answer: C

Explanation:

The force of gravity is proportional to the amount of mass in the system, and is inversely proportional to the separation distance between the two masses.

Adding mass to one of the objects would increase the gravitational field it produces, which in return increases the force of gravity.

Increasing the charge of one of the objects would technically add mass to the system, but it can be considered negligible. The adding of charge would cause an attraction between the two objects, but that is not the gravitational force. It is the Coulomb force.

Reducing the mass of one of the objects would decrease the gravitational field it produces, which would cause the force of gravity to decrease. This is the answer.

Moving the objects closer would cause the denominator of the force equation to decrease. A smaller denominator would cause the equality to increase, aka the gravitational force.

Answer:

Chemical energy to kinetic energy and gravitational potential energy

Explanation:

The kinetic and potential energy is collectively known as the mechanical energy. When you eat a large meal and then hike up a hill the energy change taking place is Chemical energy to kinetic energy and gravitational potential energy. The correct option is A.

The physical quantity which is transferred from one object to another to perform work or to heat the object is defined as the energy. The SI unit of energy is Joule and it is a derived unit.

The energy possessed by a moving body due to its motion is defined as the kinetic energy. The energy stored by an object due to its position is called the potential energy.

When we eat food, our body uses the chemical energy of food and during climbing, the body gets moved so the kinetic energy gets converted into gravitational potential energy.

Thus the correct option is A.

The number of electrons in the atom in its neutral state will be equal to 12. Therefore, option (2) is correct.

A neutral atom can be defined as one in which the number of the positive charge will be equal to the number of the negative charge. Therefore, the overall electrical charge on such an atom is zero and that type of atom is called a neutral atom.

For a neutral atom, commonly say that the number of electrons is equal to the number of protons. All chemical elements present in the modern periodic table are neutral.

Given, the electrical charge of the nucleus of an atom is equal to + 12. It means the given atom has 12 protons. As the number of protons and electrons in the neutral atom is the same, therefore the number of electrons in the given atom is equal to 12.

"Critical thinking is the analysis of available facts, evidence, observations, and arguments to form a judgment. The subject is complex; several different definitions exist, which generally include the rational, skeptical, and unbiased analysis or evaluation of factual evidence. Critical thinking is self-directed, self-disciplined, self-monitored, and self-corrective thinking. It presupposes assent to rigorous standards of excellence and mindful command of their use. It entails effective communication and problem-solving abilities as well as a commitment to overcome native egocentrism and sociocentrism." - Searched it up on Wiki, so at least I stated this-.
