If two gases a and b in separate 1 liter containers

Anton [14]

The pressure exerted when both gases are put together in a single 1 liter container is 5 atm.

<h3>What is pressure?</h3>

Pressure is the force exerted by any object on another object.

Given that, a and b separate 1 liter containers and exert pressure of 2 atm and 3 atm respectively.

When both gases a and b exert together, the pressure then

2 atm + 3 atm = 5 atm.

Thus, the pressure exerted when both gases are put together in a single 1 liter container is 5 atm.

What is mass in grams of

ELEN [110]

The mass in grams 550 mL of salt water with a density of 1.50 g/cm³ is 825grams.

<h3>DENSITY:</h3>

The mass of a substance can be calculated by multiplying the density of the substance by its volume. That is;

Mass = density × volume

According to this question, the volume of the salt is 550mL while its density is given as 1.50g/mL. The mass is calculated as follows:

Mass = 1.50g/mL × 550mL

Mass = 825grams.

Therefore, the mass in grams 550 mL of salt water with a density of 1.50 g/cm³ is 825grams.

Given the two half-reactions, what must be done in the next step before the reaction can be balanced? Au3+ --> Au I- --> I

Artyom0805 [142]

Answer:

The balance equation is

$2Au^{+3} + 6I^{-}$ → $2Au + 3I_{2}$

Explanation:

first, we have to make sure that the atoms are balanced

$Au^{+3}$ → $Au^{}$

$2I^{-}$ → $I_{2}$

then we proceed to balance charges of each half-reaction

$Au^{+3} + 3e^{-}$ → $Au^{}$

$2I^{-}$ → $I_{2}$ $+ 2e^{-}$

Now we multiply the half-reactions to match the number of electrons in each one

( $Au^{+3} + 3e^{-}$ → $Au^{}$ )x2

( $2I^{-}$ → $I_{2}$ $+ 2e^{-}$ )x3

and now we do the sum of the half-reactions

2 $Au^{+3} + 6e^{-}$ → 2 $Au^{}$

$6I^{-}$ → 3 $I_{2}$ $+ 6e^{-}$

$2Au^{+3} + 6I^{-}$ → $2Au + 3I_{2}$

note: the only atom that needed to be balanced was I

A 3.78-gram sample of iron metal is reacted with sulfur to produce 5.95 grams of iron sulfide. Determine the empirical formula o

Alexeev081 [22]

Answer:

The answer to your question is FeS₃

Explanation:

Data

mass of Fe = 3.78g

mass of S = 5.95 g

mass of FeS

Chemical Balanced Reaction

Fe + S ⇒ FeS

Process

1.- Convert the grams to moles

For Iron

55.85g of Fe -------------- 1 mol

3.78 g of Fe ----------- x

x = (3.78 x 1) / 55.85

x = 0.0677 moles

For Sulfur

32 g of S ------------------- 1 mol

5.95 g ------------------ x

x = (5.95 x 1)/32

x = 0.185 moles

2.- Divide by the lowest number of moles

Iron = 0.0677 /0.0677 = 1

Sulfur = 0.185 /0.0677 = 2.73 ≈ 3

3.- Write the empirical formula

FeS₃
