Convection

Explanation:

Heat is a form of thermal energy borne as result of thermal energy. It is observed as temperature differences between places.

There are different types of heat transfer:

Conduction
Convection
Radiation

Conduction is a heat transfer which involves the actual movement of the collision of the molecules of the medium.

Convection is a heat transfer in fluids by their movement from areas of higher to places of lower heat.

Radiation is heat transfer using electromagnetism and does not involve molecules of the medium

The process of heat transfer from ground to the air touching it is convection. It involves particles of the air.

g Gaseous methane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 0.96 g of methane

galben [10]

Answer: 2.64 g of carbon dioxide that could be produced by the chemical reaction.

Explanation:

To calculate the moles :

$\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}$

$\text{Moles of} CH_4=\frac{0.96g}{16g/mol}=0.06moles$

$\text{Moles of} O_2=\frac{6.37}{32}=0.20moles$

$CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)$

According to stoichiometry :

1 mole of $CH_4$ require = 2 moles of $O_2$

Thus 0.06 moles of $CH_4$ will require= $\frac{2}{1}\times 0.06=0.12moles$ of $O_2$

Thus $CH_4$ is the limiting reagent as it limits the formation of product and $O_2$ is the excess reagent.

As 1 moles of $CH_4$ give = 1 mole of $CO_2$

Thus 0.06 moles of $CH_4$ give = $\frac{1}{1}\times 0.06=0.06moles$ of $CO_2$

Mass of $CO_2=moles\times {\text {Molar mass}}=0.06moles\times 44g/mol=2.64g$

Thus 2.64 g of carbon dioxide that could be produced by the chemical reaction.

Calculate the density of a 20.015 g object that occupies 5.44 cm3 .

Scilla [17]

Answer:

$density = \frac{mass}{volume} \\ \\ density = \frac{20.015}{5.44} \\ \\ { \boxed{ \boxed{density = 3.679 \: g {cm}^{ - 3} }}}$
