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.

Based on the flow rate data provided for the 6 M sulfuric acid solution;

The molar mass of sulfuric acid is obtained from the molar atomic masses of it component elements.

Molar mass of H2SO4 = (2 × 1) + (32 × 1) + (16 × 4)

Molar mass of H2SO4 = (2 = 98 g/mol

Based on the flow rate data provided:

Moles of 6 M sulfuric acid in 100 L = molarity × volume

Moles of 6 M sulfuric acid in 100 L = 6 M × 100 L = 600 moles

molar flow rate = 600 mol/min

Mass of 600 moles sulfuric acid = moles × molar mass

Mass of 600 moles sulfuric acid = 600 × 98 = 58.8 kg

Mass flow rate = 58.8 kg/min

Mass of sulfuric acid in 100 L solution = volume × density

density of sulfuric acid = 1.34 g/cm^3 = 1.34 kg/L

Mass of sulfuric acid in 100 L solution = 1.34 kg/L × 100 L = 134 kg

Therefore, total mass flow rate = 134 kg/min

Answer: ionic bonds, covalent bonds

Explanation:

Got it right on my test.

Metals can forms ionic bond with non-metals by losing electrons from metals to the non-metals. They can also form metal metal bonds when they make metallic complexes and dimers. Thus option 4 is correct.

Ionic bond is the strongest type of bond formed between metals and nonmetal. Metals are electron rich and thus they are electropositive. They can donate electrons to non-metals.

Electronegative non metal atoms gain one or more electrons from the metals and thus forms the ionic compounds. Hence, ionic compounds are formed between atoms of high electronegativity difference.

Non metals like oxygen, nitrogen , halogens etc are highly electronegative and withdraw electrons from metals. Ionic compounds can have polarity if there occurs a charge separation between atoms.

Metals can also form metal-metal bonds with other metals in the case of coordination compounds and organometallic compounds. Hence, option 4 is correct.

"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-.

Answer:

the compound contains C, H, and some other element of unknownidentity, so we can’t calculate the empirical formula

Explanation:

Mass of CO2 obtained = 3.14 g

Hence number of moles of CO2 = 3.14g/44.0 g = 0.0714 mol

The mass of the carbon in the sample = 0.0714 mol × 12.0g/mol = 0.857 g

Mass of H2O obtained = 1.29 g

Hence number of moles of H2O = 1.29g/18.0 g = 0.0717 mol

The mass of the carbon in the sample = 0.0717 mol × 1g/mol = 0.0717 g

% by mass of carbon = 0.857/1 ×100 = 85.7 %

% by mass of hydrogen = 0.0717/1 × 100 = 7.17%

Mass of carbon and hydrogen = 85.7 + 7.17 = 92.87 %

Hence, there must be an unidentified element that accounts for (100 - 92.87) = 7.13% of the compound.

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.

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.

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.
