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.

A neutron should be expressed as 11H, not 01n.

Answers

The expression is wrong because the neutron should be expressed as 10n, not 01n.

A neutron is a particle that has a mass of 1 but no charge. It is a neutral particle. Seeing that the neutron is uncharged, it has a charge of zero hence zero must be written under.

The mass of the neutron is 1 so 1 must be written on top. The correct way of writing the equation for the decay of U-235 is; 10n + 235 92U.

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

Answer:  0.178 mol

Explanation:

We can use the formula M₁V₁ = M₂V₂ to determine the moles remaining after the volume is decreased due to evaporation..  

Since M₁V₁ = M₂V₂    (starting mole × starting volume = end mole × end volume)

⇒  (0.125 mol)(265 mL) =  M₂ (186 mL)

         33.125 mol/mL =  186 mL × M₂

⇒                      M₂ = 33.125 mol/mL ÷ 186 mL

convert 2.5 X 10^24 atoms of copper to grams of copper

Answers

2.5 X 10²⁴ atoms of copper is equivalent to 266.7g of Cu.

HOW TO CALCULATE MASS:

The mass of a substance can be calculated by multiplying the number of moles of the substance by its molar mass. That is;

mass of substance (g) = no. of moles (mol) × molar mass (g/mol)

However, the number of moles of copper must first be calculated by dividing the number of atoms by Avogadro's number as follows:

no. of moles of Cu = 2.5 X 10²⁴ ÷ 6.02 × 10²³

no. of moles = 2.5/6.02 × 10²⁴-²³

no. of moles = 0.42 × 10¹

no. of moles = 4.2moles of copper.

Molar mass of copper = 63.5g/mol

Mass of copper = 4.2mol × 63.5g/mol

Mass of copper = 266.7g

Therefore, 2.5 X 10²⁴ atoms of copper is equivalent to 266.7g of Cu.

which element has the highest monetary value?

B) Silver

C) nickel

Answers

Answer:

A. gold has the highest monetary value?

Among the given elements, gold has the highest monetary value. So the correct option is A.

What is gold?

Gold (Au) is a chemical element that belongs to Period 6's Group 11 (Ib) and is a thick, glossy golden valuable metal. Gold has historically been extremely valued due to a number of characteristics. It is typically found in nature in a relatively pure form, is appealing in colour and brightness, resilient to the point of virtual indestructibility, and very flexible.

Due to its perceived worth from the beginning, gold has a history that is unmatched by that of any other metal. Gold is one of the densest metals.

It is a good heat and electrical conductor. It is also the softest, most malleable, and ductile of all the elements; a troy ounce (31.1 grammes) of gold may be hammered into gold leaf, which can be crushed into sheets as thin as 187 square feet (approximately 17 square metres).

Therefore the correct option is A.

13. Acid-catalyzed dehydration-condensation reactions of carboxylic acids and alcohols produce chemicals called
esters.
i. Using carbon skeletal notation, write the dehydration-condensation reaction that occurs between ethanol
and butanoic acid.
ii. What is the name of this ester?

Answers

Answer:

A condensation reaction joins two larger molecules by splitting out a smaller molecule — usually water or ammonia — between them.

In an esterification reaction, an OH  from the acid and an H from the alcohol form a molecule of water.

The larger parts join to form the ester.

Ethanol and butanoic acid react to form ethyl butanoate.

Acid-catalyzed dehydration-condensation reactions of carboxylic acids and alcohols produce chemicals called "esters". The dehydration-condensation reaction occurs between 'ethanol' and 'butanoic acid' giving an ester called as "ethyl butanoate".

What is an ester and how it is formed?Esters are produced when carboxylic acids are heated with alcohols in the presence of an acid catalyst. The catalyst is usually concentrated sulphuric acid. Dry hydrogen chloride gas is used in some cases, but these tend to involve aromatic esters (ones containing a benzene ring).Esters are represented by the formula RCOOR', where R and R' are hydrocarbon groups. The chemical reaction occurring in the formation of the ester is known as an esterification reaction.

The reaction that occurs between ethanol and butanoic acid:

Ethanol reacts with butanoic acid in the presence of an acid-catalyst and gives ethyl butanoate as ester and water as products. If an acid reacts with a base, salt and water are the products. But ester is not a salt.

i) The carbon skeletal notation for the given reaction is shown below.

ii) The ester is named "ethyl butanoate".

Why does silicone dioxide have a high melting point ?

Answers

Answer:

Where SiO2 has strong covalent bonds between molecules, SO3 only has weak van der waals intermolecular forces holding its molecules together. Since covalent bonds require more energy to overcome than van der waals, SiO2 requires a higher temperature than SO3 to melt, thus SiO2 has a higher melting point.
