A hot air balloon can have a volume of 2950 cubic meters (2.95 ✕ 106 liters) and operate at temperatures up to 250°F (121°C). As
TiliK225 [7]

Answer:

2.64 × 10⁶ g

Explanation:

We can find the mass of air using the ideal gas equation.

P.V=n.R.T=\frac{m}{M} .R.T

where,

P is the pressure (P = 1.00 atm)

V is the volume (V = 2.95 × 10⁶ L)

n is the number of moles

R is the ideal gas constant (0.08206atm.L/mol.K)

T is the absolute temperature (121°C + 273 = 394 K)

m is the mass

M is the molar mass (28.09 g/mol)

m=\frac{P.V.M}{R.T} =\frac{1.00atm \times 2.95 \times 10^{6} L \times 28.97g/mol}{(0.08206atm.L/mol.K) \times 394 K } =2.64 \times 10^{6} g

How would adding the catalyst nitrogen monoxide (NO) affect this reaction?
steposvetlana [31]

If nitrogen monoxide (NO) is added to 2SO2(g) + O2(g) → 2SO3(g),

it will react with O2 and decrease the reaction rate by lowering the amount of O2.  So the answer is C.  NO decreases collisions between the SO2 and O2 molecules.

If 25.0 mL of a 2.00 M CaCl2 solution is used for the reaction
RideAnS [48]

0.1 moles of chloride ions were involved  in the reaction if 25.0 mL of a 2.00 M CaCl2 solution is used for the reaction.

Explanation:

Data given:

volume of CaCl_{2} = 25 ml 0r 0.025

molarity of the calcium chloride solution = 2M

number of chloride ions =?

Balance chemical reaction:

Ca + 2Cl_{2} ⇒Ca_{} Cl_{2}

number of moles in 25 ml is calculated as:

molarity = \frac{number of moles}{volume}

number of moles of calcium chloride  = molarity x volume

putting the values in the equation:

number of moles = 2 x 0.025

                            = 0.05 moles of calcium chloride

1 mole of  CaCl_{2}  decomposes as 1 calcium ion and 2 chloride ions

so 0.05 moles will have x moles of chloride ion

\frac{2}{1} = \frac{x}{0.05}

x= 0.1

0.1 moles of chloride ions will be involved in the reaction.
