Potassium outermost electron occupy "4s" orbital
Answer:
Sc(OH)₃ = 96 g/mol
Explanation:
Gram formula mass:
Gram formula mass is the atomic mass of one mole of any substance.
It can be calculated by adding the mass of each atoms present in substance.
Sc(OH)₃:
Atomic mass of Sc = 45 amu
Atomic mas of O = 16 amu
There are three atoms of O = 16 ×3
Atomic mas of H = 1 amu
There are three atoms of H = 1 ×3
Gram formula mass of Sc(OH)₃:
Sc(OH)₃ = 45 ×1 + 16 ×3 + 1 ×3
Sc(OH)₃ = 96 g/mol
Answer:
false
Explanation:
There are a equal number of protons and electrons in neutral atoms.
There are two types of 'quantities' namely: scalar and vector
A 'vector' is a quantity that has both magnitude and direction whereas a 'scalar' has only magnitude.
Magnitude is a measure or the size of the quantity or object.
In the given example of the vector: '75 mph to the north'
Magnitude is the number 75 mph
Direction is north
