Answer:
1.Mg+O2.......MgO2
Explanation:
2.Very reactive towards halogens and reacts with water at room temperature. 3, Magnesium oxide is a simple basic oxide. 4.It will react with water to form magnesium hydroxide which is a base turning red litmus to blue 5.should be white. hope it helped. I help people although when I post a question it is left unanswered and then gets answers after two days when I don't really need it
Answer:
One molecule is made of two or more atoms bonded together.
Explanation:
Molecule is a substance which is made up chemically by two or more same or different atoms. The atoms joint together in a molecule due to a chemical bond. This chemical bond is formed either by mutual sharing of electrons or transfer of electrons between two atoms.
Examples:
A molecule of H₂O (water) is made up of two atoms of Hydrogen and one atom of Oxygen (H-O-H).
A molecule of CO₂ (Carbon Dioxide) is formed when a carbon atom is bonded to two oxygen atoms via a double bonds (O=C=O).
A molecule of N₂ (Nitrogen Gas) is formed between two nitrogen atoms through a triple bond (N≡N).
Answer: Δn for the following equation in relating Kc to Kp is 2.
Explanation:
The balanced chemical equation is:
Relation of 
with 
is given by the formula:
Where,
= equilibrium constant in terms of partial pressure
= equilibrium constant in terms of concentration
R = Gas constant
T = temperature
= change in number of moles of gas particles = 
Putting values in above equation, we get:
Thus the value of Δn for the following equation in relating Kc to Kp is 2.
Density = mass/volume
D = 500 g /200 cm^3
D = 2.5 g/cm^3
