Answer:
The smallest tiny particles of matter which can't be divided further is called atom, i.e., an atom is the smallest building block of matter. For example: Sodium (Na), Hydrogen (H), Oxygen (O), etc.
Answer:
A series circuit is defined as the circuit in which a number of resistances are connected one after the other.. In a series circuit, the flow of current follows a single path.
A parallel circuit is defined as the circuit in which a number of resistances are linked across each other in such a way that one terminal of each resistance is connected to form a junction point while the remaining end is also connected to form another point.
You havent added the diagram so i cant tell you the answer, but i added the definition of each circuit, see if that helps!
Molarity is defined as the number of moles of solute per 1 L of solvent.
the mass of NaCl in the solution is 87.75 g
number of moles of NaCl is calculated by dividing mass present by molar mass
number of NaCl moles = 87.75 g / 58.44 g/mol = 1.502 mol
the number of NaCl moles in 500 mL is - 1.502 mol
therefore number of NaCl moles in 1000 mL is - 1.502 mol/ 500 mL x 1000 mL/L = 3.004 mol
molarity of NaCl is - 3.004 M
answer is D. 3.00 M
- No of protons=No of electrons=15
<h3>Mass no:-No of neutrons+No of protons </h3>
Now
- It has atomic no 15 hence its Phosphorus(P)
Electronic configuration:-
