The substances that are formed by a chemical change are called the product.
While the state of matter in which a material has a definite volume and a definite shape is the solid.
In a chemical reaction, the reactant on the left hand side undergoes a chemical change and gives product.
While in a solid state, a material has a definite volume and a definite shape is the solid.
The process should be natural erosion
Answer:
3.88kg
Explanation:
weight=mass_of_body(m) x acceleration_due_to_gravity(g)
The weight is given and acceleration is also give
For mass divide the weight by acceleration.
Answer:
See explanation
Explanation:
The periodic table shows the atomic number and mass number of each element.
We know that the atomic number shows;
- The number of protons in the nucleus of the atom
- The number of electrons in the neutral atom of the element.
So we obtain the number of protons and electrons by looking at the atomic number shown in the periodic table.
We also know that;
Mass number = Number of protons + number of neutrons
Since number of protons = atomic number of the atom
Number of neutrons = Mass number - atomic number
Hence we obtain the number of protons by subtracting the atomic number from the mass number given in the periodic table.
