a sample of gold has a mass of 96.5 g and a volume of 5.00 cm3. the density of gold is
Answer:
19.3 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 96.5 g
volume = 5 cm³
We have
[tex]density = \frac{96.5}{5} \\ = 19.3[/tex]
We have the final answer as
19.3 g/cm³Hope this helps you

- ¿Qué otros materiales de tu entorno podrías utilizar que te permita mejorar tu filtrador de agua?
Suelo, grava, bolas de algodón, material de desecho, carbón, arena y astillas de madera.
El suelo, la grava, las bolas de algodón, los desechos, el carbón, la arena y las astillas de madera son materiales extraídos del medio ambiente que nos permiten mejorar la filtración del agua porque estos materiales filtran partículas y otras impurezas del agua y la hacen potable.
La arena y la grava se consideran buenos filtros de agua porque forman capas permeables que filtran el agua. El agua puede pasar lentamente a través de estas capas permeables y la mayoría de las partículas de suciedad quedan atrapadas, por lo que podemos concluir que los materiales anteriores se pueden utilizar como filtros de agua.

Calculate the medullary index of a hair whose diameter is 110
microns wide and whose medulla measures 58 microns. Is this
a human or animal hair?
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.
What is hair medullary index?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:
relative proportions of the elements in a chemical reaction
A molecule or a compound can easily be represented by their formula.Subscripts in chemical formulas are used to indicate the relative proportions of the elements in a compound.
What is chemical formula?A chemical formula represent the identity and number of elements in a molecule or compound. Each element in periodic table has their own symbols. For example, hydrogen is H, oxygen having O, N for nitrogen, Na for sodium etc.
These chemical symbols are came from the first one or two letters of the Latin names of the elements. The number of these elements in a compound is given as subscripts of their symbols.
For example, there are two hydrogens and one oxygen in water and the formula is H₂O. Similarly the formula of carbon dioxide is CO₂ where one carbon and two oxygens are present. In this way the compounds can be easily identified and distuinguished using their chemical formulas.

explain why the yield of grain increases when nitrate-containing fertiliser is added.
Explanation:
Nitrogen is an essential element for plant growth and development; however, due to environmental pollution, high nitrate concentrations accumulate in the edible parts of these leafy vegetables, particularly if excessive nitrogen fertilizer has been applied. Consuming these crops can harm human health; thus, developing a suitable strategy for the agricultural application of nitrogen fertilizer is important. Organic, inorganic, and liquid fertilizers were utilized in this study to investigate their effect on nitrate concentrations and lettuce growth. The results of this pot experiment show that the total nitrogen concentration in soil and the nitrate concentration in lettuce increased as the amount of nitrogen fertilizer increased. If the recommended amount of inorganic fertilizer (200 kg·N·ha−1) is used as a standard of comparison, lettuce augmented with organic fertilizers (200 kg·N·ha−1) have significantly longer and wider leaves, higher shoot, and lower concentrations of nitrate.
Nitrogen is a critical element for plant growth and development; however, due to environmental pollution, high nitrate concentrations get in the edible regions of these leafy vegetables, particularly if excessive nitrogen fertilizer has been involved.
What are nitrate-containing fertilizer?The main nitrate fertilizers exist as ammonium, sodium, potassium, and calcium salts. Nitrate exists highly reachable and can efficiently travel with water from the soil if there stands excessive rainfall and can get groundwater.
Nitrates in the soil exist as a primary source of nitrogen which is important for plant growth. Under normal conditions, nitrates are transformed to protein in the plant at about identical rates as they exist absorbed into the root system.

Are cations nonmetals
and anions are metals?
Answer:
First, each element that forms cations is a metal, except for one (hydrogen), while each element that forms anions is a nonmetal. This is actually one of the chemical properties of metals and nonmetals: metals tend to form cations, while nonmetals tend to form anions. Are positive ions metals or nonmetals?

The photoelectron spectrum for the element nitrogen is represented above. Which of the following best explains how the spectrum is consistent with the electron shell model of the ato
f the atom?
A. The leftmost peak represents the valence electrons.
B. The two peaks at the right represent a total of three electrons.
C. The electrons in the ls sublevel have the smallest binding energy
D. The electrons in the 2p sublevel have the smallest binding energy
Answer:
D. Is the correct option.
Explanation:
2p level contains the electrons furthest from the nucleus in the case of Nitrogen thus it's much easier to disperse/remove the electrons from the shell due to low pull of nucleus energy.
The best explanation of how the spectrum is consistent with the electron shell model of the atom is the electrons in the 2p sub level have the smallest binding energy. Thus, option D is correct.
What is photoelectron spectrum?
Photoemission spectroscopy also known as photoelectron spectroscopy which photoelectric effect is the process in which electron are get energy from external source of energy like sunlight deals with energy measurement of energy emission or electrons emitted from solids, gases or liquids by the process of photoelectric effect,
Photoelectric effect is the process in which electron are get energy from external source of energy like sunlight and get excited and comes in excited state from the ground state due to this process continuos flow of electron is take place and after that flow of energy is takes place.
