It is believed the major reason for the decline in amphibian species is _______.
a.
death through disease
b.
changing reproductive habits
c.

d.
climate change

Answers

Answer: It is believed the major reason for the decline in amphibian species is death through disease.

Explanation:

The major reason for the decline in amphibian species is climate change.

Amphibians are organisms that can live on land and in water. They are

usually found around moist areas because they need water bodies to cool

off in order for their survival.

Climate change is characterized by an increase in temperature which

doesn't favor them as they lose more water which thereby threatens survival

and leads to their decline in the ecosystem.

How do protons, neutrons, and electrons differ in terms of their electrical charges and
locations within the atom?

Answers

Answer:

Protons and Neutrons are large particles and are densely compacted into the nucleus of the atom. Protons are electrochemically positive in charge and the Neutrons are electrochemically neutral in charge. ... Electrons are electrochemically negatively charged particles that move random around the nucleus

Explanation:

Protons are positively charged, neutrons are neutral and they both are located in the nucleus whereas electrons are negatively charged and located outside the nucleus.

Explanation:

Atom is defined as the smallest unit of a matter.It consists of three subatomic particles: protons, neutrons, electrons.Protons and neutrons are located inside the nucleus. They are also known as nucleonsElectrons are located outside the nucleus.Protons carry a positive charge, electrons carry a negative charge, and neutrons carry no charge (neutral).

So from this, we conclude that the protons are positively charged, neutrons are neutral and they both are located in the nucleus whereas electrons are negatively charged and located outside the nucleus

O [Rn]7s2547
O [Ne]3s 3p
O [Xe]6s25d1
Plz help

Answers

Answer:

the answer is [Rn]7s25f14 (first option)

Explanation:

i took the test

The electronic configuration for nobelium (No) is [Rn]7s²5f¹⁴, hence the correct option is A.

What is electronic configuration?

The distribution of an element's atoms' electrons throughout several atomic orbitals is symbolically represented by the electronic configuration of that element.

A standardized nomenclature is used for expressing electron configurations, in which the energy level and type of orbital are written first, followed by the number of electrons in the orbital, which is expressed in superscript.

The atomic number of nobelium (No) is 102.

The number of protons is equal to the atomic number, which is 102.

The number of electrons is equal to the number of protons, which is 102.

Therefore, electronic configuration for nobelium (No) is [Rn]7s²5f¹⁴.

Oil and water placed in a jar will separate. Even when
shaken and mixed, the oil still separates from the
water.
Which best describes oil and water?
Oil and water are highly soluble because they have
separate chemical properties.
Oil and water have a low solubility because they
have separate chemical properties.
Oil and water are highly soluble because they exert
different pressures
Oil and water have a low solubility because they
exert different pressures.

Answers

The answer is option B :)

According to the concept of solubility, oil and water have a low solubility because they have separate chemical properties.

What is solubility?

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

Q1.What is the mass of 5 moles Of 1.Mg 2.CaCO3 Q2. Calculate the number of atoms in 10g of Na Q3.calculate the number of molecules in 10g of NaCl Q.4.What is Avogadro's number? How many number of atoms are present in 4g of Oxygen?

Answers

Answer:

Explanation:

Q1) as we know that moles=given mass/molar mass

     mass of 5 moles of Mg is

mass =moles*molar mass

mass=5*24

mass=120 g

mass of 5 moles of CaCO3 is

mass= moles*molar mass

mass=5*100=500

Q2) number of atoms in 10 g Na

first we need number of moles of sodium

moles =mass/molar mass

moles=10/23=0.43

now we know that moles=number of atoms /avogadro number

for number of atom the formula become

number of atom=moles*avogadro number

number of atom=0.43*6.023*10^23=2.6*10^23

Q3)number of molecule in 10 g of NaCl

again we need number of moles of NaCl

moles=given mass/molar mass

moles=10/58.5=0.17

now number of molecules=moles*avogadro number

number of molecules=0.17*6.023*10^23=1.02*10^23

Q4) avogadro number is the number of particles(atoms,molecules,ions) present in one mole of a substance its value is 6.023*10^23

Q5)Number of atoms in 4g of oxygen

again we need number of moles of oxygen

moles=mass/molar mass

moles=4/16=0.25

now number of atoms=moles*avogadro number

number of atoms=0.25*6.023*10^23 =1.5*10^23
