Explanation:

Solids have a definite shape and volume. Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.

The kinetic theory of matter (particle theory) says that all matter consists of many, very small particles which are constantly moving or in a continual state of motion.

Your question seems incomplete, the probable complete question is:

What synthetic products are derived from the natural resource aluminum? What kind of chemical processes are used to create these synthetic products?

Answer:

0.225 L = 225 mL

Explanation:

Charles' Law states that for a fixed pressure, the volume is directly proportional to the temperature, which means things expand at the same rate as the rate of it being heated up

Mathematically, we can write that as:

V1/T1 = V2/T2, where 1 and 2 are the two situations

So, when we substitute the values in, we get:

0.25 L/298 K = V2/268 K

Rearranging this, we get:

(0.25/298) x 268 = 0.225 L = 225 mL.

This also makes sense, as the volume reduced a little when the temperature reduced (cooled down)

Let me know if this makes sense, and hope I helped! :)

The medullary index of hair is the ratio of medullary diameter to the diameter of hair. Thus the medullary  of  hair with 110 microns and medulla diameter of 58 microns is 0.533. This is an animal hair.

Medullary index of hair is the ratio of diameter of the medullary part and the diameter of the hair strand. From this value, we can identify whether the sample hair is of humans or animals.

Hair is made proteins called keratin. The protein structure of hair vary from human to  human even one hair strand to the other and similar way it is different in animal hair too.

The hair strand of humans are thin than the hair strands of animals. Thus the medullary index of humans is 0.333 or less. If the index is 0.50 or greater it is of animals.

Here the diameter of hair is 110 microns and that of medulla is 58 microns thus medullary index is 58/110 = 0.55 microns. Which means that it is an animal hair.

Answer:The answer to your question is It will be formed 0.39 moles of H₂

Data

moles of H₂ = ?

moles of HCl = 0.78

moles of Zinc = excess

Balanced chemical reaction

             2 HCl  +  Zn  ⇒  1 H₂  +  ZnCl₂

Process

Explanation:

1.- Use proportions to solve this problem. Consider the coefficients of the balanced reaction.

              2 moles of HCl ---------------------- 1 mol of H₂

              0.78 moles of HCl -----------------  x

              x = (0.78 x 1) / 2

- Simplification

             x = 0.78 / 2

- Result

             x = 0.39 moles of H₂

Explanation:

Streak is the microscopic remains of minerals in powder form after being rubbed with porcelain plates. The streaks do not have orderly arranged lattice structure or unit cells.

They are randomly arranged and microscopic size powders. The streak of minerals cannot be distinguished easily as it mostly appears similar for all minerals.

Thus, among the given options streak is one in the property of minerals. We can rely upon streaks as it cannot be easily affected by impurities.

The Law of Conservation of Matter states that matter cannot be created or destroyed. In a physical change, substances can change form, but the total mass remains the same. In a chemical change, the total mass of the reactants always equals the total mass of the products. Materials.

Explanation:

microfilaments are composed of repeating actin subunits in a thin double-helix arrangement.

Given the six solutions, the solution that will separate aqueous barium ion and aqueous lead(II) ion is ammonium chloride.

In qualitative analysis, it is common to separate substances in solution by introducing a solution that preferentially precipitates one of the ions in solutions while leaving the other one in solution.

In this case, we know that all chlorides are soluble except those of lead, mercury and silver according to the solubility rules. Hence, if ammonium chloride is added to a solution of aqueous barium ion and aqueous lead(II) ion, lead II chloride is preferentially precipitated hence the ions are separated.

When fossil fuels are burnt, CO2 is released into the air and is taken up by plants during photosynthesis to form glucose and subsequently starch.

Fossil fuels contain a large proportion of carbon atoms. When fossil fuels are burnt, these carbon atoms are released as carbon dioxide and escape to the atmosphere as atmospheric CO2 in air.

Recall that plants take up the CO2 in air during the process of photosynthesis. This CO2 becomes combined with water in the presence of sunlight to form glucose.

This glucose is converted to starch and stored in plant tissues. This is how the  carbon atom inside a fossil fuel  becomes a carbon atom inside a plant.
