A gamma ray has a frequency of 1 x 10^20 Hz and has a speed of c. What is the
wavelength?
Answer:
λ = 3.0 × 10⁻¹² m
Explanation:
Speed of Light = Wavelength × frequency
c = λν
Step 1: Define
c = 3.0 × 10⁸ m/s
λ = unknown
ν = 1 × 10²⁰ Hz
Step 2: Substitute and Evaluate for λ
3.0 × 10⁸ m/s = λ · 1 × 10²⁰ Hz
λ = 3.0 × 10⁸ m/s ÷ 1 × 10²⁰ Hz
λ = 3.0 × 10⁻¹² m

What is the hybridization of the C atoms in C2Cl4 ?
Answer:
sp2
Explanation:
Orbital hybridization is defined as the changes in the orbitals of atoms when they pair with electrons of other atoms to form chemical bonds.
C atoms in C2Cl4 or tetrachloroethene have a total of three bond pairs, two with each chlorine atom and one with other carbon atom and zero lone pairs. Thus, C atoms in C2Cl4 is sp2 hybridized.
Hence, the correct answer is "sp2".
The hybridization of the C atoms in C2Cl4 is sp² hybridized.
The concept of hybridization deals with the merging of atomic orbitals to produce fresh hybridized orbitals, which impact molecule geometry and bonding characteristics.
In the given compound, C2Cl4 (tetrachloroethene)
There is a substitution of all the hydrogen atoms attached to the organic compound ethene with chlorine to produce tetrachloroethene. The two carbon atoms are doubly bonded to each other with two chlorine attached to each of the carbon atoms diagonally given rise to a bond angle of 120°. Thus, the resulting hybridization of the C atom is sp² hybridized.
Therefore, we can conclude that the hybridization of the C atoms in C2Cl4 is sp² hybridized.

B. When the molecule contains polar bonds
C. When the molecule contains hydrogen bonds
D. When the molecule contains nonpolar bonds
Answer:
B When the molecule contains polar bonds.
Explanation:
AP-EXpert
The shape of a molecule affect its polarity, when the molecule contains polar bonds because polarity depends on polar bonds.
What is the effect on polarity?The polarization of a molecule greatly depends on the shape of the molecule. The net dipole moment occurs only due to the uneven distribution of electrons between the two atoms.
So we can conclude that the shape of a molecule affect its polarity, when the molecule contains polar bonds because polarity depends on polar bonds.

at the bottom of the ocean a rock has a mass 25 g. At sea level the same rock wilk have a mass of:
less than 25 g
more than 25 g
exactly 25 g
Answer:
exactly 25 g
Explanation:
The mass of an object is universally the same every where. Even in outer space.
This is because, mass is the amount of matter contained in a substance. Since there is no loss in the amount of matter, the mass of the body stays the same.
It is weight that is subjected to changes with the value of gravity. Weight differs from places to places. A place with higher gravity will have a higher value of weight for any given mass.Mass accounts for every individual matter present in a substance.
When they remain the same, mass does not change. Only a change in the amount of matter in a body can cause variation in mass.
Therefore, at the bottom of the ocean, a body will have the same mass as on top and even at sea level.

c. exactly 25 g

correct.
option 1: movement
2: none of these answers are correct
3:growth
4:development
Answer:
1. movement
3. growth
4. development
Explanation:
ATP provides a source of chemical energy that powers all cell functions.
Any process in the body that requires energy relies on the conversion of ATP to ADP and the associated release of chemical energy. Therefore, movement, growth, and development all use ATP to take place.
Which describes an atom that has fewer neutrons than protons and more electrons than protons?
0negative compound
0positive compound
0positive ion
0negative ion
Answer:
Option d is correct = Negative ion
Explanation:
We know that an atom consist of electrons, protons and neutrons. Neutrons and protons are present inside the nucleus while electrons are present out side the nucleus. Electron has a negative charge and is written as e⁻. The mass of electron is 9.10938356×10⁻³¹ Kg . While mass of proton and neutron is 1.672623×10⁻²⁷Kg and 1.674929×10⁻²⁷ Kg respectively.
Symbol of proton= P⁺
Symbol of neutron= n⁰
The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons. The umber of protons and electrons are always equal to make the atom electrically neutral and when an atom loses its valance electron the number of protons increases and thus positive charge increased and atom form cation.
When an atom gain electron negative charge increase because of more number of electron thus atom form negative ion or anion. For example,
Anion formation:
X + e⁻ → X⁻
Cation formation:
X → X⁺ + e⁻
Thus option d is correct option.

Calculate the volume of a liquid with a density of 5.35 g/mL and a mass of 62.0 g.
Answer to the proper significant figures and include the proper unit.
My answer was 11.6 mL, but it was wrong.
Answer:
V= 12mL
Explanation:
you had the right idea with your Significant figures however, when we divide we see that it requires 2 significant figures as our least amount. this is because when looking at our division, 62 has 2 sig. fig. while 5.35 has a total 3. when looking at your answer we see that you had a total of 3 sig. figures. so in actuakity you had to round up to 12 and not to the tenths because the decimal makes .6 count as your third sig fig.

cubic centimeter (cm^3) has the same volume as a
Answer:
1 cc=1 ml=0.001 liter
Explanation:
One cubic centimeter has the same volume as one milliliters. Both are equally used in analytical problems to express the volume of a substance.
What is volume ?Volume is a physical quantity that measures the total space occupied by a substance. Volume is an extensive quantity and thus depends on the amount of the substance.
The mass of a substance per unit volume is called its density. Volume is dependent on the intermolecular forces between the particles of the substance. The SI unit of volume is liter (L). Other units are ml, cm³, dm³ etc.
One cubic centimeter has the volume as one milliliters.
Hence, 1 cm³ = 1 ml
1000 m or 1000 cm³ is one liter of the substance.
