The atomic number of Arsenic (As) is 33 and the average atomic mass is 74.92 amu. A neutral arsenic atom will have protons
Given :
The atomic number of Arsenic (As) is 33.
The average atomic mass is 74.92 amu.
To Find :
A neutral arsenic atom will have protons.
Solution :
We know, atomic mass is the sum of number of protons and neutrons.
Also, atomic number is the number of protons present in an atom.
Therefore, a neutral arsenic atom will have 33 protons.

How many grams are there in 4.30 x 10²⁶ molecules of H₂SO₄?
Mass of H₂SO₄ : 69,972 g
Further explanationA 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]

[tex]\tt mass=mol\times MW\\\\mass=7.14.10^2\times 98\\\\mass=69,972~g[/tex]
Which of the following properties would a substance that has metallic bonding
normally have?
I. thermal conductivity
II. electrical conductivity
III. malleability
IV. ductility
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 conductivitymalleabilityductilityMetals 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.

Which of the following best describes the relationship between the speed of sound and the type of medium?
A.
Sound travels slower in air because of the large distance between air particles
B.
Sound travels slower in solids because of the small distance between solid particles
C.
Sound travels slower in air because of the small distance between air particles
D.
Sound travels slower in solids because of the large distance between solid particles
Answer:
A. Sound travels slower in air because of the large distance between air particles
Explanation:
Sound is a mechanical wave that requires a medium for its propagation. Without a medium, sound cannot go through easily or readily. This implies that sound cannot be propagated through a vacuum.
A vacuum is an empty space without any particles in side. Sound waves travel fastest the most in solids because the particles are dense and close to one another. The speed of sound in air is the least because of the large distance between air particles. Therefore, the speed of sound is medium dependenthow many moles of oxygen molecules can be produced from 6 moles of lead oxide
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
6 : 1/2×6 =3 mol
three moles of oxygen molecules are produced.

What makes Carbon-14 so useful in “carbon dating” or “radiodating”?
Answer:
Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon. ... The carbon-14 method was developed by the American physicist Willard F. Libby about 1946.
Explanation:
Under which conditions does a real gas behave most like an ideal gas? A. At low temperatures and high pressures B. At low temperatures and low pressures C. At high temperatures and high pressures D. At high temperatures and low pressures
Answer: D. At high temperatures and low pressures
Explanation:
At low temperature and high pressure, the kinetic energy of gas molecules is negligible and molecules will have negligible forces of attraction. So real gases will behave least like an ideal gas under such conditions.
At high temperature and low pressure, energy due to intermolecular forces becomes less important in comparison to the kinetic energy of particles. The size of molecules also become less significant than the empty space between the gas molecules. So real gases behave in a similar manner to ideal gases at high temperature and low pressure.

Many of the lunar craters are due to volcanic eruptions true or false
Answer:
false
Explanation:
Craters on the Moon are caused by asteroids and meteorites colliding with the lunar surface. The Moon's surface is covered with thousands of craters. ... It also has very little geologic activity (like volcanoes) or weathering (from wind or rain) so craters remain intact from billions of years.

To make a balanced equation, 6 H2O + 6 CO2 ---> C6H12O6 + _
Answer:
6O₂
General Formulas and Concepts:
Chemistry/Biology
Photosynthesis Equation: 6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂Explanation:
Most of the equation comes from the Photosynthesis Equation. Plants take in water and carbon dioxide and sunlight (energy) to produce glucose and oxygen. When we balance the equation and predict reaction. we should get 6O₂ as our answer.
When building electric circuits,_______ flow along the path ( wires, energy source, and resistor(s)).
-neutrons
-matter
-electrons
-protons
Electron is negatively charged particle. When building electric circuits electron flow along the path. so, option C is correct.
What is Electron ?Electrons are fundamental to many physical processes, including gravity, electromagnetic interactions, weak interactions, electricity, magnetism, chemistry, and thermal conductivity.
The outer shells of atoms in the common items you encounter are made up of matter particles called electrons.
A negatively charged subatomic particle known as an electron can either be free or attached to an atom (not bound). One of the three main types of particles within an atom is an electron that is bonded to it.
The other two are protons and neutrons. The nucleus of an atom is made up of electrons, protons, and neutrons together.
Thus, Option C is correct.

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.
