Answer:
Releases a lot of energy. When hydrogen a highly reactive element reacts with oxygen, it does so using immense force, when the bonds break high amounts of emery is released.
Explanation:
In Homogeneous, "Homo" means same, so homogeneous means the same nature or kind.
Heterogeneous is the opposite. It means diverse.
A good way to remember is just think of homo as same. And the rest should come to you.
Hope this helps! :)
An element that is composed of a multiple bond is one that is formed between 2 atoms, and the electrons are shared, therefore, resulting in a neutral charge.
Answer:
electrons form the atoms f one material may move to the atoms of the other material. The movement of electrons from one atom to another changes the charge of the atoms. When an atom loses electrons, it is left with more protons than electrons, so it then has a positive charge. when an atom gains electrons, it has more electrons than protons so its charge is negative.
Explanation:
Answer:
14 moles
Explanation:
For an Ideal gas,
PV = nRT...................... Equation 1
Where P = Pressure, V = Volume, n = number of mole, R = Molar gas constant.
make n the subject of the equation
n = PV/RT.................. Equation 2
Given: P = 14.297 atm, V = 22.9 L = 22.9 dm³, T = 12 °C = (12+273) K = 285 K.
Constant: R = 0.082 atm.dm³/K.mol
Substitute these values into equation 2
n = (14.297×22.9)/(285×0.082)
n = 327.4013/23.37
n = 14.009
n ≈ 14 moles
