The size of an atom would be described in _______.

Answers

Answer 1

Answer:

atomic radius

Explanation:

so radius

Answer 2

Answer:

Explanation:

The average size of an atom is about 100 picometers or one ten-billionth of a meter. Almost all of the mass of an atom is in its nucleus; almost all of the volume of an atom is occupied by electrons. The number of protons (also known as its atomic number) determines the element. Varying the number of neutrons results in isotopes.

4. How does the
productivity of
photosynthesis affect the
productivity of cellular
respiration?

Answers

Answer: it’s the chemicals between the biological

Explanation:

The productivity of photosynthesis affect the productivity of cellular respiration by providing energy.

What is photosynthesis?

Photosynthesis is a process where plants prepare their food in the presence of sunlight.

Photosynthesis process chemically illustrated as :

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

From the above it is clear that carbohydrate is produced in the photosynthesis process and this carbohydrate provide energy to the plant for the completion of another chemical process. So, for the cellular respiration plants use this energy.

Hence, the productivity of photosynthesis directly affect the productivity of cellular respiration.

6. Which of the following molecules has a central atom with precisely two unshared
pairs of electrons?
methane, CH4
ammonia, NH3
hydrocyanic acid, HCN
water, H20
CLEAR ALL

Answers

Answer:

water, H20

Explanation:

From the given choices, only water has two unshared or lone pairs of electrons in its central atom.

The formula of water is:

              H₂O

H is hydrogen with 1 electron

O is oxygen with 8 electrons and 6 valence electrons

To form the covalent bond, the 6 valence electrons are involved. Two out of the 6 bonds with the two oxygen.

The remaining 4 gives the two lone pairs.

How many grams are there in 4.30 x 10²⁶ molecules of H₂SO₄?

Answers

Mass of H₂SO₄ : 69,972 g

Further explanation  

A mole is a number of particles(atoms, molecules, ions)  in a substance

This refers to the atomic total of the 12 gr C-12  which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles  

Can be formulated :

N = n x No

N = number of particles

n = mol

No = 6.02.10²³ = Avogadro's number

moles of H₂SO₄ :

[tex]\tt mol=\dfrac{N}{No}\\\\mol=\dfrac{4.3\times 10^{26}}{6.02\times 10^{23}}\\\\mol=7.14\times 10^2[/tex]

how many moles of oxygen molecules can be produced from 6 moles of lead oxide

Answers

Answer:

Moles of oxygen molecules produced = 3 mol

Explanation:

Given data:

Moles of oxygen molecules produced = ?

Number of moles of lead oxide decomposed = 6 mol

Solution:

Chemical equation:

2PbO₂          →        2PbO + O₂

Now we will compare the moles of oxygen and lead oxide.

                   PbO₂        :          O₂

                      2           :            1

Which of the following properties would a substance that has metallic bonding
normally have?
I. thermal conductivity
II. electrical conductivity
III. malleability
IV. ductility

Answers

Answer:

I, II, III,IV

Explanation:

Metals are known to possess metallic bonds. In a metallic bond, electro-positive metals loose electrons which form a cloud of electrons which exerts an attractive force on the positive metallic ions. This attractive force holds the metal atoms together in the crystal lattice.

The physical properties of metals include;

I. thermal conductivity

II. electrical conductivity

III. malleability

IV. ductility

Hence, substances that exhibit properties I-IV are metals and have metallic bonds.

The following properties which a substance that has metallic bonding

normally have include

thermal conductivityelectrical conductivitymalleabilityductility

Metals are elements which have metallic bonding which is always strong as

it helps to form a lattice.

Metals are good conductors of heat and electric current , they can also be

bent in to different shapes . This means it has all the properties listed above.

A radioactive nucleus can change from one element to another. How does this happen?

Answers

Radioactive decay happens when an unstable atomic nucleus spontaneously changes to a lower-energy state and spits out a bit of radiation. This process changes the atom to a different element or a different isotope

A radioactive decay is occurring by the emission of charged particles such alpha or beta to form a new stable atom with changes mass number and atomic number.

What is radioactive decay?

Heavy unstable radioactive elements undergo nuclear decay by which they form a stable isotope or new atom with changed atomic number. There are two types of nuclear decays mainly. They are alpha decay and beta decay.

During alpha decay isotopes with higher mass number undergo alpha emission and forming a new species with mass number reduced by 4 units and atomic number reduced by 2 units.

In the case of beta- decay, electrons are emitted from the atom and then forming a new atom with atomic number increased by one unit. For an electron capture process, an electron is captured to the atom forming an element with atomic number reduced by one.
