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.
Answer:
Induction
Explanation:
When a body is brought in contact with another, electrons are rearranged by contact.
When a body is rubbed against one another, charging by friction occurs.
The process whereby electrons are rearranged without direct contact with one another is called induction.
By induction electrons can get charged without them having to be in contact with one another.
- When a charged body is brought to the vicinity of the electrons, either an attraction or repulsion force is set up.
- Similar charges causes repulsion
- If a negatively charged body is brought near the electrons, there would be heavy repulsion and the electrons would be forced to rearranged.
- This effect is product as a result of a force field.
Answer:
Yes
Explanation:
Yes, you can test this by comparing grades you received when you studied and when you did not study
The number of milliliters of the solution that you need to give to the patient is calculated as follows
32mg is in 1 ml of the solution
what about 320mg
=( 320mg x 1 ml) /32mg= 10ml
Answer:
You haven't given enough information, you have to tell us how many grams of which reactant are present, as well as the initial and final temperatures of the solution.
