1. BONDING PATTERNS BETWEEN ATOMS.
2. TYPES OF MATTER IN SOLIDS.
Solids generally have their constituent particles arranged in a pattern known as crystalline structure. The crystalline structure of the solid is due to the types of matter and the chemical bonds that exist between the particles of solids. The constituent particles of a solid can be atoms, ions or molecules.
Answer:
Na2SO4 + Bi(NO3)3 = Bi2(SO4)3 + NaNO3
Answer:
B
Explanation:
Elements in a group are determined by the number of valence electrons
Elements in a period are determined by the number of electrons shell
The electronic configuration of the element is
2,8,8
the number of valence electron is 8 that means it is in Group 8/O
the number of electron shell is 3 that means it is in period (row) 3
Group 8/O elements are called Noble gases
<h3>
Answer:</h3>
Velocity is 1 m/s
<h3>
Explanation:</h3>
<u>We are given;</u>
- Mass of the kiddy train is 1000 kg
- Radius of the curve is 5.0 m
- Centripetal force is 2000 N
We are required to determine the maximum speed of the train.
- Centripetal force refers to the force experienced by an object in a circular motion towards the center of a circular path.
- It is calculated by the formula;
- , where m is the mass, v is the velocity and r is the radius of the circular path.
- Therefore, using the formula we can find the maximum speed.
Therefore, the maximum speed of the train is 1 m/s
