Answer: 203.5 millilitres
Explanation: ???
Answer:
B
Explanation:
the element is boron, therefore B is the symbol
Answer:
it would break when it hits the ground
Explanation:
Answer:
Mass = 23.36 g
Explanation:
Given data:
Number of particles of CO₂ = 3.20 ×10²³
Mass of CO₂ = ?
Solution:
1 mole contain 6.022×`10²³ particles,
3.20 ×10²³ particles × 1 mol / 6.022×`10²³ particles
0.531 mol
Mass of CO₂:
Mass = number of moles × molar mass
Molar mass = 44 g/mol
Mass = 0.531 mol× 44 g/mol
Mass = 23.36 g
Answer:
Energy required to remove an electron from the atom.
Explanation:
Energy required to remove an electron from an atom describe ionization energy because in chemistry, ionization energy in is the amount of energy needed to remove electrons from the atoms or ions of chemical species.
Ionization energy increases as we move across the period of elements in the group and this is because electrons are bond tighter by high effective nuclear charge and ionization energy of elements increases down the group because electrons are bond together in lower energy orbitals.
