salantis [7]

Answer:

The answer to your question is:

Explanation:

a)

Metals: are shiny, malleable and ductile, they can conduct electricity and heat,  form cations in aqueous solutions.

Nonmetals: non-lustrous, brittle, not good conductors of heat and electricity, form anions in aqueous solutions.

b)

Metals are located in the left side of the periodic table

Nonmetals are located in the right side of the periodic table.

c)

Metal are use to make pans because they are good conductors of heat and also are malleable and ductile.

Nonmetals are used to make sleeping bags and coolers because they do not conduct heat so they can isolate matter.

Explain why a propane torch is lit inside a hot air balloon during preflight preparations. Which gas law applies?
Olegator [25]

Propane torch is lit inside a hot air balloon during pre-flight preparation because the heat from the touch is needed to heat the cold air inside the balloon, so that the air will expand and become less dense and rise, thus providing a lift for the balloon. This is line with charle's law, which states that, the volume of a fixed mass of ideal gas is directly proportional to the absolute temperature. This law implies that, as the temperature of the air inside the balloon increase, the volume of the balloon also increases.

For the reaction shown, calculate how many moles of NO2 form when each amount of reactant completely reacts.
Anton [14]

Answer:-  2.4 mol NO_2 .

Solution:- It asks to calculate the moles of NO_2 formed when 1.2 moles of N_2O_5 are reacted.

There is 2:4 mol ratio between N_2O_5 and NO_2 . So, the moles of reactant are multiplied by the mol ratio to get the moles of NO_2 . The calculations are shown below:

1.2mol N_2O_5(\frac{4mol NO_2}{2mol N_2O_5})

= 2.4 mol NO_2

So, 2.4 moles of NO_2 are formed when 1.2 moles of  N_2O_5 were reacted.
