Which refers to the type of chemical bond that involves the transfer of electrons between atoms? O metallic O polar covalent Oionic O covalent
Answer:
C-
Ionic
Explanation:
Just did the quiz
The bonding occurs between the valence electron of an atom. The ionic bond involves the transfer of electrons between atoms. Thus, option c is correct.
What is an ionic bond?A chemical bond that involves the complete transfer of electron/s from one element to another in a molecule or compound is an ionic bond.
The ionic bonds comprise cations that gave the electron to another element called the anion that gained or accepted the electron. This results in an attractive force between them to form a bond.
The positive and negative charges attract one another which leads to the formation of the ionic bond. The most common example is NaCl in which sodium has a positive and chloride has a negative charge.
Therefore, option c. ionic bond involves the transfer of electrons.

The bowling ball weighs 3.6 kg and the bowling pin weighs 1.36 kg. If the mass of the bowling ball is increased to 7.2 kg and the bowling pin is increased to 2.7 kg, what is the effect on the force between them? Group of answer choices
Answer:
F₂ = 3.97 F₁
Hence, the force will be increased by a factor of 3.97
Explanation:
The force between the ball and the bowling pin is given by Newton's Gravitational Law, as follows:
F = Gm₁m₂/r²
where,
F = Force
G = Gravitational Constant
m₁ = mass of ball
m₂ = mass of bowling pin
r = distance between ball and bowling pin
So, initially:
F₁ = G(3.6 kg)(1.36 kg)/r²
F₁ = 4.896 G/r²
After increase in masses:
F₂ = G(7.2 kg)(2.7 kg)/r²
F₂ = 19.44 G/r²
F₂/F₁ = (19.44 Gr²)/(4.896 G/r²)
F₂ = 3.97 F₁
Hence, the force will be increased by a factor of 3.97
table salt has a density of 2.16g/cm3. a cylindrical box holds 4.25 kg of salt. what is the volume, in cm3 occupied by the salt in the box?
Given parameters:
Density of table salt = 2.16g/cm³
Mass of table salt = 4.25kg = [tex]\frac{0.00425}{2.16}[/tex][tex]\frac{0.00425}{2.16}[/tex]g (1000g = 1kg)
Unknown:
Volume of table salt = ?
Solution:
To find the volume of the table salt, let us state the relationship between density, mass and volume.
Density is the mass per unit volume of substance.
Density = [tex]\frac{mass}{volume}[/tex]
Since the unknown is volume;
Density x volume = mass
Volume = [tex]\frac{mass}{density}[/tex]
Input the parameters and solve';
Volume = [tex]\frac{0.000425}{2.16}[/tex] = 1.97 x 10⁻³cm³
Volume of the table salt is 1.97 x 10⁻³cm³

What makes the atomic radius change along a period in the periodic table?
A. The increased atomic mass makes the atomic radius bigger.
B. More electrons in the valence shell make the radius bigger.
C. More electrons pair in orbitals, making the atomic radius smaller.
D. More protons in the nucleus pull the electrons in, making the
atomic radius smaller
Answer:
D
Explanation:
More protons in the nucleus pull the electrons in, making the atomic radius smaller. Therefore, the correct option is option D.
The atomic radius is determined by the nucleus's balance between the attracting force of positively charged protons and the repelling force of electrons.
The most crucial element in calculating the average atomic radius is not Option A. Although atomic mass typically increases with time, increasing nuclear charge has a greater impact on atomic size.
Over time, Option B has no discernible impact on atomic radius. Although the number of valence electrons changes over time, increasing nuclear charge has the biggest impact on atomic size. The valence shell is the outermost electron shell.
The gradual decrease in atomic radius is unaffected by Option C. The most frequent electron pairing occurs within orbitals of the same energy level, and it has little impact on atomic size over a period.
Therefore, the correct option is option D.

To bring heavy boxes down a fight of stairs. Tyrone uses a camp. He shoes the boxes down the ramp. The movement transforms ce type d energy into the fons made togos
the way that most of the energy is transformed?
potential energy into chemical energy and mechanical energy
o potential energy into light energy and mechanical energy
o potential energy into sound and chemical energy
O potential energy into heat and kinetic energy
Answer:
This question is unclear, the comprehensive question is:
To bring heavy boxes down a flight of stairs, Tyrone uses a ramp. He slides the boxes down the ramp. The movement transforms one type of energy into two other forms. Which of the following describes the way that most of the energy is transformed:
ANSWER:
Potential energy into heat and kinetic energy
Explanation:
According to this question, a ramp is used to bring heavy boxes down a flight of stairs. Tyrone does this by sliding the boxes down the ramp. The ramp is in a fixed position i.e. not moving, meaning the energy in the ramp is POTENTIAL ENERGY.
However, when the boxes slide down the ramp, the potential energy transforms to energy due to motion called KINETIC ENERGY, and HEAT ENERGY, which is caused by the friction between the boxes and the ramp.
Therefore, the potential energy of the ramp is transformed to kinetic energy in the boxes and heat energy.
a boy and a girl are pulling a heavy crate at the same time with 7 units of force each what is the net force on the object is the object balanced or unbalanced
Answer:
Net force= 0N or 0units
Object is balanced
Explanation:
Net force refers to all the sum total of all forces acting upon an object. In this case, a boy and a girl are pulling a heavy crate at the same time with 7 units of force each.
- This means that the force exerted on the crate by the boy is F1 = 7units
- The force exerted on the crate by the girl is F2 = -7units
Hence, the Fnet = F1 + F2
Fnet = 7 + (-7)
Fnet = 0 units
An object which possess a net force is said to be unbalanced, while an object with no net force i.e 0 units or N. Hence, the heavy crate in this case being pulled by a net force of 0units is BALANCED.
The force applied on the object is a balanced force since the object is at equilibrium.
The given parameters;
force applied by the boy, F₁ = 7 N
force applied by the girl, F₂ = 7 N
The net force on the object is the resultant of the two equal both opposite directed force.
Let the boy's direction be positive
Let the girl's direction be negative
The resultant of the two forces is calculated as;
[tex]\Sigma F_x = F_1 + F_2\\\\\Sigma F_x = (7 \ N) + (-7 \ N)\\\\\Sigma F_x = 0[/tex]
Thus, the force applied on the object is a balanced force since the object is at equilibrium.
