1 answer:

3 0

The reactant being used up is called limiting reagent as it limits the total amount of product produced.

if 4 units of HCL gives 2 units of Cl therefore
4:2
0.98:x
x=(0.98*2) /4
x=0.49L

the pressure of 8.4 of nitrogen gas in a flexible container is decreased to one-half its original size

lutik1710 [3]

The new volume is 33.6 L.

<h3>What is volume?</h3>

Volume can be described as a measure of occupied three-dimensional space.

From the question above, we obtain the following data:

Initial volume (V1) = 8.40 L L

Initial pressure (P1) = P

Initial temperature (T1) = T

Final pressure (P2) = one-half the original pressure = ½P

Final temperature (T2) = double the original temperature = 2T

Final volume (V2) = what?

The new volume can be obtained by using the universal gas law;

P1V1/ T1 = P2V2 /T2

P × 8.40 / T = ½P × V2 /2T

P × 8.40 / T = P × Volume 2 / 4T

Cross multiply

T × P × Volume 2 = P × 8.40 × 4T

Divide both side by T × P

Volume 2 = (P × 8.40 × 4T) /T × P

Volume 2 = 8.40 × 4

Volume 2 = 33.6 L

Thus, the new volume of the gas is 33.6 L.

When is gas behavior most ideal?

Fiesta28 [93]

Answer: so B

Explanation:

Generally, a gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to intermolecular forces becomes less significant compared with the particles' kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.

What is the volume, in l, of 0.682 moles of o'what 2 gas having a temperature of 68.2 ºc and pressure of 5.82 atm?

klemol [59]

We will use Ideal gas equation. PV=nRT where P= pressure(in atm)=5.82atm V=Volume=? n= moles of gases=0.682 R = gas constant= 0.0821L atm / mol K T = temperature= 68.2 C= 68.2 + 273.15 = 341.35 K V= nRT/ P= 0.682 X 0.0821 X 341.35/ 5.82 V= 3.284 L.

Breyana and her friend found a piece of metal which they want to

alina1380 [7]

Answer:

The density of beryllium is 1.85 g/cm³. Thus given metal is beryllium.

Explanation:

Given data:

Mass of metal = 37 g

Volume of metal = 20cm³

Which metal is this = ?

Solution:

We will solve this problem by using density formula. After finding density we will check from literature which metal has a density similar to our calculated density.

d = m/v

d = 37 g/ 20cm³

d = 1.85 g/cm³

The density of beryllium is 1.85 g/cm³. Thus given metal is beryllium.
