Answer:
Pressure
Explanation:
Basically when you are pressing something you are applying force over an area thus Pressure is force divided by area.
Mass of Magnesium nitrate produced : 593.2 g

The reaction equation is the chemical formula of reagents and product substances
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
2HNO₃ + Mg(OH)₂ → Mg(NO₃)₂ + 2H₂0
mol HNO₃ = 8
From the equation, mol ratio of HNO₃ : Mg(NO₃)₂ = 2 : 1, so mol Mg(NO₃)₂ :
Mass Mg(NO₃)₂(MW=148,3 g/mol) :
Answer:
a molecule is the <u>smallest</u> particle of a substance that can normally exist independenty
Answer:
Electrons are always marked negative Hence electronic energy is also always taken as negative. It is because when an electron is at infinite distance from nucleus , there the kinetic energy of that electron can not be calculated. So, it is taken to be zero . ... And thus the energy of electron becomes less negative
Finding the volume of regular geometric objects uses standard formulas. The volume of a box equals length times width times height, for example. Not every object, however, fits a formula. Water displacement is best only used for irregular shaped objects.
