Answer:

The particles have a medium amount of kinetic energy and slide past one another

Explanation:

If particles move at a high rate of speed its gas, and if they vibrate in place and they have a fixed volume and shape its probably a solid. So a medium amount of kinetic enery is correct.

Gold is element 79 and its symbol is Au.

Answer:

If you're just looking at the Lewis Structure from the perspective of the octet rule, it does appear that the structure is correct. Dinitrogen always has a lone pair of electrons which could conceivably be used for dative bonding as you suggest. So from that perspective there appears to be nothing wrong at all - other than that it doesn't exist in nature in this way.

Answer:

Organelles; role.

Explanation:

A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells. Generally, cells have the ability to independently replicate themselves. In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles with their respective functions in all living organisms such as trees, birds, and bacteria include;

1. Nucleus : it controls all the activities taking place in the cell and the synthesis of proteins.

2. Mitochondria : it provides all the energy required in the cell by transforming energy forms.

3. Lysosomes : they are responsible for absorbing materials and breaking the materials taken in by the cells.

4. Chromosomes : they give sets of instructions for the synthesis of products.

5. Ribosomes : they are involved in the build up of proteins.

6. Endoplasmic Reticulum : this is where the ribosomes perform their tasks.

7. Cytoskeleton : they help to maintain and support the shape of the cells.

8. Vesicles : they ensure proteins are properly transported to the right and exact location.

9. Golgi apparatus : it prepares the protein for export by chemically tagging them.

10. Cell membrane : is the wall of the cell and typically controls what leaves and enters the cell.

Hence, cells are made of many parts, or organelles, that help the cell do its job. Each cell organelle has a specific function, or role.

answer below:

Explanation:

1) 4 Al + 3 O2 --> 2Al2O3.

2) Al mol= 28/27 = 1.037mol

O mol= 45/16 = 2.812mol

Al : O

4 : 2

x : 2.812

cross multiply

4 x 2.812/2  = 5.624 mol of Al

Al is limiting reactant

3) 28/5.246 = 5.34product can be formed (not that much sure)

4) 45/ 0.5185 = 86.79

86.79 - 5.34 = 81.45g

5) 50 / 81.45 x 100 = 61.39% ( i guess)

Answer:

28.23 g NH₃

Explanation:

The balanced chemical equation is:

N₂(g) + 3 H₂(g) → 2 NH₃(g)

Thus, 1 mol of N₂ reacts with 2 moles of H₂ to produce 2 moles of NH₃. We convert the moles to mass (in grams) by using the molecular weight (MW) of each compound:

MW(N₂) = 2 x 14 g/mol = 28 g/mol

mass N₂= 1 mol x 28 g/mol = 28 g

MW(H₂) = 2 x 1 g/mol = 2 g/mol

mass H₂ = 3 mol x 2 g/mol = 6 g

MW(NH₃) = 14 g/mol + (3 x 1 g/mol) = 17 g/mol

mass NH₃= 2 moles x 17 g/mol = 34 g

Now, we have to figure out which is the limiting reactant. For this, we know that the stoichiometric ratio is 28 g N₂/6 g H₂. If we have 36.85 g of H₂, we need the following mass of N₂:

36.85 g H₂ x 28 g N₂/6 g H₂ = 171.97 g N₂

We have 23.15 g N₂ and we need 171.97 g. So, we have lesser N₂ than we need. Thus, the limiting reactant is N₂.

Now, we calculate the product (NH₃) by using the stoichiometric ratio 34 g NH₃/28 g N₂, with the mass of N₂ we have:

23.25 g N₂ x 34 g NH₃/28 g N₂ = 28.23 g NH₃

Therefore, the maximum amount of NH₃ that can be produced is 28.23 grams.

Answer: 35.6 g/mol

Explanation: I guessed and got it correct

The molar volume of any gas behaving ideally at STP is 22.414 L. The molar mass of the gas at STP is 35.59 g.

The molar mass of a substance is defined as the mass of one mole of molecules. In other words one gram molecular mass of a substance is same to its molar mass in g mol⁻¹.

The molar mass of a substance can be obtained by adding the atomic masses of each elements.  At 0°C and 1 atm, 1 mole of any gas behaving ideally occupies a volume of 22.414 L.

Here 5.00 L of the gas at STP has a mass of 7.94. Then the molar mass of 22.414 liters of the gas can be calculated as:

7.94 × 22.414/5.00 = 35.59 g.

Thus the molar mass of the gas is 35.59 g.

Answer:

Genotypic ratio = 1 Bb: 1 bb

Phenotypic ratio = 1 black rabbit : 1 brown rabbit

Explanation:

This question involves a gene coding for hair color in rabbits. The allele for Black hair (B) is dominant to the allele for brown hair (b).

According to this question, a black rabbit whose mother is brown haired (bb) is crossed with a brown hair rabbit. This means that the black rabbit will have a genotype 'Bb' while the brown rabbit will have a genotype 'bb'. Each parent will produce the following gametes:

Bb - B and b

bb - b and b

Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

Bb, Bb, bb and bb

This means that the;

Genotypic ratio = 1 Bb: 1 bb

Phenotypic ratio = 1 black rabbit : 1 brown rabbit

Answer:

H2 would have a coefficient of 2.

Explanation:

According to the balanced chemical equation, the coefficient of hydrogen is 4.

Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.

A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .

The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.
