A 6.00 L container of N_2 has a temperature of 273 K. Calculate the volume if the temperature is doubled.
vfiekz [6]
V1/T1 =V2/T2 (using charles law)

V1=6.00
V2=?
T1=273
T2=273

Making V2 the subject of formula the equation then becomes

V2= V1xT2/T1

6.00x263/273=6.0L

How many moles of methane will react to form 3.2 moles of carbon dioxide?
Hunter-Best [27]

Answer:

3.2 moles

Explanation:

First, we'll begin by writing a balanced equation for the Combustion of methane to produce carbon dioxide. This is illustrated below:

CH4 + 2O2 —> CO2 + 2H2O

From the balanced equation above,

1 mole of methane (CH4) reacted to produced 1 mole of carbon dioxide (CO2).

Therefore, 3.2 moles of methane (CH4) will react to produce 3.2 moles of carbon dioxide (CO2).

From the illustration above, 3.2 moles of methane is needed to produce 3.2 moles of carbon dioxide.

A sample of 0.0860 g of sodium chloride is added to 30.0 mL of 0.050 M silver nitrate, resulting in the formation of a precipita
Grace [21]

Answer:

0.21 g

Explanation:

The equation of the reaction is;

NaCl(aq) + AgNO3(aq) -----> NaNO3(aq) + AgCl(s)

Number of moles of NaCl= 0.0860 g /58.5 g/mol = 0.00147 moles

Number of moles of AgNO3 = 30/1000 L × 0.050 M = 0.0015 moles

Since the reaction is 1:1, NaCl is the limiting reactant.

1 mole of NaCl yields 1 mole of AgCl

0.00147 moles of NaCl yields 0.00147 moles of AgCl

Mass of precipitate formed = 0.00147 moles of AgCl × 143.32 g/mol

= 0.21 g
