Answer : The mass of sulfur trioxide is, 488.8 grams.

Explanation : Given,

Moles of sulfur trioxide = 6.11 mole

Molar mass of sulfur trioxide = 80 g/mole

Formula used :

\text{Mass of }SO_3=\text{Moles of }SO_3\times \text{Molar mass of }SO_3

Now put all the given values in this formula, we get the mass of sulfur trioxide.

\text{Mass of }SO_3=6.11mole\times 80g/mole=488.8g

Therefore, the mass of sulfur trioxide is, 488.8 grams.

It would be approximately 489 g, rounded for significant figures. The calculator given answer would be 489.20326. To get that, all you have to do is take your 6.11 moles and multiply it by 80.066 (the molar mass) divided by 1 mol to cancel out the unit.

125 ml of nitrogen gas is collected at 70.0 degrees Celsius. The pressure
dybincka [34]

Answer: Volume of the gas at STP is 22.53 L.

Explanation:

Given : Volume = 125 mL   (as 1 mL = 0.001 L) = 0.125 L

Temperature = 70^{o}C = (70 + 273) K = 343 K

Pressure = 125 kPa = 125 kPa \times \frac{0.01 atm}{1 kPa} = 1.25 atm

According to the ideal gas equation, the volume of given nitrogen gas is calculated as follows.

PV = nRT

where,

P = pressure

V = volume

n = number of moles

R = gas constant = 0.0821 L atm/mol K

T = temperature

Substitute the values into above formula as follows.

1.25 atm \times V = 1 mol \times 0.0821 L atm/mol K \times 343 K\\V = \frac{1 mol \times 0.0821 L atm/mol K \times 343 K}{1.25 atm}\\= \frac{28.1603}{1.25} L\\= 22.53 L

Hence, volume of the gas at STP is 22.53 L.

Bronze is an alloy made of mostly copper (Cu) and tin (Sn). What type of bond forms bronze?
Snezhnost [94]

Answer:

A. Metallic bond

Explanation:

Think about it: copper and tin are both common metals. That's how we know it's a metallic bond!

Why not B: Covalent bonds are between two nonmetals.

Why not C: Ionic bonds are between a nonmetal and a metal.

Why not D: Paired bond isn't a common phrase in chemistry.

Which statement is TRUE about oxidation-reduction reactions? a. Every oxidation must be accompanied by a reduction. b. There are
Tomtit [17]

Answer:

Every oxidation must be accompanied by a reduction.

Explanation:

Oxidation and reduction are complementary processes. There can be no oxidation without reduction and vice versa. It is actually a given an take affair. A specie looses electrons which must be gained by another specie to complete the process. This explains why the selected option is the correct one.

Do atoms lend and borrow electrons from inner shells
zaharov [31]
False. They don't borrow electrons at all. They already have their respective electron affinities. This is called as electronegativity, and it's an occurence where it already has its own from its actual structure. It never borrows any electrons at all.
