explain how a metal and a non-metal form an ION when they chemically react together.

Answers

Answer:

When metals react with non-metals, electrons are transferred from the metal atoms to the non-metal atoms, forming ions. The resulting compound is called an ionic compound. In all of these reactions, the metal atoms give electrons to the non-metal atoms.

A spiracle ball of lead has a diameter of 3.5 cm. What is the mass of the sphere if lead has a density of 11.34 g

Answers

Answer:

mass =  volume  x   density

volume = πr²

   since Diameter = 3.5 cm

   then   radius = 1.75cm

∴ volume  =  π  x  (1.75cm)³

                ≈  16.8369731 cm³

Thus mass  =  16.8369731 cm³  x  11.34  g / cm³

                   =  190.93 g

2. Why do researchers need a lot of data to monitor a species population? What trends can
you see in the data that you would have missed otherwise?

Science

Answers

To study the population of a species we have to collect many data regarding the factors affecting the growth of the species and those which adversely affects their survival.

What is population monitoring?

A key element of conservation practice and policy is species population monitoring, which is defined here as the regular, systematic gathering of data to detect long-term changes in the populations of wild species.

To examine regional, chronological, taxonomic, and methodological patterns in global species monitoring, we built a database of over 1200 programs .

Through standardized web searches, an online stakeholder survey, thorough national searches in a selection of nations, and a review of international biodiversity databases, we discovered monitoring systems.

Most taxonomic groups continue to have scant and poorly coordinated monitoring, and the majority of the data produced are elusive and unlikely to contribute to larger processes for biodiversity conservation.

B
C1 = trigonal planar, C2 = tetrahedral
C
C1 = bent, C2 = trigonal planar
D
C1 = tetrahedral, C2 = linear

Answers

The hybridization state of the atom determines its shape in the molecule. C1  is sp2 hybridized and has trigonal planar geometry while C2 is sp3 hybridized and has a tetrahedral geometry.

The shape of a molecule or a moiety in a molecule is determined by the number of electron pairs that are present on the valence shell of the central atom in the molecule.

The hybridization state of the atom also determines the shape of the atom. In the compound, the carbon atom labelled 1 is sp2 hybridized so it will have a trigonal planar geometry. The carbon atom labelled 2 is sp3 hybridized hence it is tetrahedral.

Plss help
thx

Answers

Answer: There you go.

Explanation:

These types of decay involve the nuclear capture of electrons or emission of electrons or positrons, and thus acts to move a nucleus toward the ratio of neutrons to protons that has the least energy for a given total number of nucleons. This consequently produces a more stable (lower energy) nucleus.

When radioactive decay occurs, the original nucleus splits into daughter nuclei and the resulting nucleus is more stable than the original nucleus. The nucleus can be of a different element than the original.

Unstable nuclei often undergo radioactive decay. In a radioactive decay, the unstable nucleus is broken up into other nuclei. Usually, the nuclei formed during radioactive decay are smaller in mass compared to the original nucleus.

Also, the resulting nucleus is more stable than the original nucleus. The nucleus can be of a different element than the original.

The quantity which determines how two atoms bond is; The difference in their electronegativities.

The electronegativity value of an element is a measure of its electron affinity.

In essence, the electronegativity value of an element determines if the element is an electron donor or acceptor.

Ultimately, the difference between the electronegativities of two atoms determines how the atoms bond.

Aeration basins increase the rate of bacteria working to break down the organic matter in wastewater. True or False?

Answers

Answer:

it is true

Explanation:

Aeration basins increase the rate of bacteria working to break down the organic matter in wastewater is true.

What is aeration basins?

Aeration basins is defined as the biomass consumes both oxygen and organic pollution, resulting in net microorganism growth and carbon dioxide release.

It can also be defined as the process of introducing air into wastewater in order to allow aerobic bio-degradation of pollutant components.

Aeration is frequently used to reduce the amount of carbon dioxide released by a treatment process.

It is the best methods for waste water treatment .

The main disadvantage of the aeration process is that too much oxygen is absorbed and the water becomes corrosive.

Thus, aeration basins increase the rate of bacteria working to break down the organic matter in wastewater is true.
