Answer:

the final pressure is 3.94 atm

Explanation:

Given that,

Initial pressure (P1) = 3.80atm

Initial temperature (T1) = 25°C

since the standard unit of temperature is Kelvin, convert 25°C to Kelvin

(25°C + 273= 298K)

Final pressure P2 = ?

Final temperature T2 = 36°C

(36°C + 273= 309K)

Since pressure and temperature are given while volume is held constant, apply the formula for Pressure's law

P1/T1 = P2/T2

3.80 atm / 298K = P2 / 309K

To get the value of P2, cross multiply

3.80 atm x 309K = P2 x 298K

1174.2 atm•K = 298K•P2

Divide both sides by 298K

1174.2 atm•K/298K = 298K•P2/298K

3.94 atm = P2

Thus, the final pressure is 3.94 atm

Initial temperature (T1) = 25°C

1174.2 atm•K = 298K•P2

Divide both sides by 298K

1174.2 atm•K/298K = 298K•P2/298K

3.94 atm = P2

Thus, the final pressure is 3.94 atm

Answer:

Plants and animals are pH sensitive. The growth of plants is dependent on the nature of the soil. If the pH of the soil is greater than 7 and is alkaline, then the plants cannot grow in the soil.

A 3.42 gram sample of an unknown gas is found to occupy a volume of 1.90 L at a pressure of 547 mm Hg and a temperature of 33 °C
liq [111]
Use the Ideal Gas Law to find the moles of gas first.

Be sure to convert T from Celsius to Kelvin by adding 273.

Also I prefer to deal with pressure in atm rather than mmHg, so divide the pressure by 760 to get it in atm.

PV = nRT —> n = PV/RT
P = 547 mmHg = 547/760 atm = 0.720 atm
V = 1.90 L
T = 33°C = 33 + 273 K = 306 K
R = 0.08206 L atm / mol K

n = (0.720 atm)(1.90 L) / (0.08206 L atm / mol K)(306 K) = 0.0545 mol of gas

Now divide grams by mol to get the molecular weight.

3.42 g / 0.0545 mol = 62.8 g/mol

How do i balance the first chemical reaction above?? plz plz help
soldier1979 [14.2K]

Answer:

2K +F₂→ 2KF

Explanation:

When we balance an equation, we are trying to ensure that the number of atoms of each element is the same on both sides of the arrow.

On the left side of the arrow, there is 1 K atom and 2 F atoms. On the right, there is 1 K and 1 F atom.

Since the number of K atoms is currently balanced, balance the number of F atoms.

K +F₂→ 2KF

Now, that the number of F atoms is balanced on both sides, check if the number of K atoms are balanced.

<u>Left</u>

K atoms: 1

F atoms: 2

<u>Right</u>

K atoms: 2

F atoms: 2

The number of K atoms is not balanced.

2K +F₂→ 2KF

<u>Left</u>

K atoms: 2

F atoms: 2

<u>Right</u>

K atoms: 2

F atoms: 2

The equation is now balanced.
