Answer:
A) Has properties of both metals and nonmetals - Barium.
B) Nonreactive gas - Neon.
C) Great conductor of heat and electricity - Boron.
D) Malleable and highly reactive - Potassium.
Explanation:
hope it helps .
Graph D.
Charles's law states that at the same pressure, the Volumen of a gas is proportional to its temperature (absolute temperature).
This is
V = K T, where K is the constant of proportionallity.
You can also write it in the form
V1 / V2 = T1/ Ts
When Temperature rise Volumen rise in a proportional way. If Temperature doubles Volumen doubles, if Tempearature is decreases to on third, Volume will decrease to one third.
Neutralization reaction means the reactants must be one acid and one alkali, and the product will be H2O and metal salt.
The only one satisfying this will be B
Answer: The coefficient of nitrogen in the given equation is 2.
Explanation: The reaction for the oxidation of methamphentamine with oxygen gas in the body is given by:
By Stoichiometry,
4 moles of methamphentamine reacts with 55 moles of oxygen gas to produce 40 moles of carbon dioxide gas, 30 moles of water and 2 moles of nitrogen gas.
Coefficient of 
Coefficient of 
Coefficient of 
Coefficient of 
Coefficient of 
Hence, the coefficient of nitrogen in the given equation is 2.
