When ionic bonds form compound structures in a solid state, they arrange in latticed, crystalline patterns.
What does this say about the structure of the compound on the molecular level? What does it say about
the properties of that compound?
Answer:
Structures are determined by two principal factors: the relative sizes of the ions and the ratio of the numbers of positive and negative ions in the compound.
Ionic compounds at a molecular level are arranged in definite patterns to give a crystalline structure leading to a high melting point, high boiling point and high density in ionic compounds.
In ionic bond is formed when a metal transfers electrons to a nonmetal and an ion pair is formed. The ions are held together by strong electrostatic interaction as described by Coulomb's law.
However, the smallest unit of an ionic substance is called the formula unit. The compound arranges itself in definite patterns to form a crystalline lattice. Hence, the structure of ionic compound is highly ordered. This leads to a high melting point, high boiling point and high density in ionic compounds.

A crate is pulled by a force (parallel to the incline) up a rough incline. The crate has an initial spped shown in the figure below. The crate is pulled a distance of 8.24m on the incline by a force of 150N force. b) What is the speed of the crate after it is pulled the 8.24M? Answer in units of m/s.
Answer:
(a) Kinetic energy of the cart is 648.32 J.
(b) Speed of the cart is 11.44 m/s.
Explanation:
From the attached below figure we came to know that,
Mass of the crate is 10 kg (m)
Initial speed of the crate is 1.2 m/s (v)
Coefficient of friction on a rough plane is 0.286 (µ)
Force on the cart is 150 N (F)
The distance which crate is moved (d) is 8.05 m.
Calculation of kinetic energy:
Acceleration of the cart:
We know that,
F = F – m × g × sinθ - µ × m × g × cosθ (F = ma)
m × a = F – m × g × sinθ - µ × m × g × cosθ
10 × a = 150 – (10 × 9.8 × sin 27) – (0.286 × 10 × 9.8 × cos 27)
10 × a = 150 – 44.49 – 24.97
10 × a = 80.54
Calculation of speed:
Change in kinetic energy = m × a × d
Change in kinetic energy = 10 × 8.054 × 8.05
Change in kinetic energy = 648.32 J

How can you determine the mass number of the daughter product after alpha decay has taken place?
Answer:
Reduce the mass number of the parent by 4
Explanation:
To determine the mass number of the daughter product after alpha decay has taken place, reduce the mass number of the parent by 4.
An alpha particle reduces the mass number of the parent by 4 and the atomic number by 2.
It has the the same structure as an helium atom.
So, since helium has mass number of 4 and atomic number of 2, it reduces the daughter product by this number.
A basketball with a mass of 0.5 kilograms is accelerated at 2
meters per second2. The net force acting on the mass is
A) 0.5 N
B) ON
C) 1N
D) 2N
Answer: 1N
Explanation: its not 0N.
If a basketball with a mass of 0.5 kilograms is accelerated at 2 meters per second². The net force acting on the mass is 1 Newton, therefore the correct answer is option C.
What is Newton's second law?Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.
As given in the problem, if a basketball with a mass of 0.5 kilograms is accelerated at 2 meters per second², then we have to find out the force acting on the basketball.
The net force acting on the basketball = 0.5 × 2
= 1 N
Thus, the net force acting on the mass is 1 Newton, therefore the correct answer is option C .

A 15.0kg object is resting on the earth. What is the mass and weight of the object?
Answer:
The mass of the object is 15.0 kg
The weight of the object is 147.15 N
Explanation:
The mass of the object is the quantity of matter contained in the object or the measure of the its property of inertia.
The mass is constant through out the universe
The mass of the object is given as 15.0 kg
The weight of the object is the force of attraction of the Earth on the object
The weight is dependent on the interacting objects.
The weight of the object = The mass of the object × Acceleration due to gravity
Where;
The acceleration due to gravity, g = 9.81 m/s²
∴ The weight of the object = 15.0 kg × 9.81 m/s²= 147.15 N
The weight of the object = 147.15 N
