A glass tube contains mercury. What would be the height of the column of mercury which would create pressure equal to 1.00 atm

1 answer:

7 0

Since 1.00 atm is equal to 760 mmHg, the height of the column of mercury which would create pressure equal to 1.00 atm is 760 mm or 76 cm

<h3>What are the units of pressure?</h3>

Pressure is defined as the force acting perpendicularly per unit area of a surface.

The units of pressure include;

millimetres of mercury, mmHg
aatmospheres, atm,
pascals, Pa
Newtons per square metre, N/m^2

1 atmosphere is equal to 760 mmHg.

Therefore, the height of the column of mercury which would create pressure equal to 1.00 atm is 760 mm or 76 cm

which number should be placed before F2 on the reactants side equation to make equation balanced? Xe + ___F2 > XeF4

Ivahew [28]

There are four F atoms on the products side.

Since two more F atoms are required on the reactant side, you multiply the number of F2 molecules by two.

So 2 should be placed in front of F2

(c) O2 gas is transferred from a 3 L vessel containing oxygen at 4 atm to an evacuated 20 L vessel at a constant temperature of

Fudgin [204]

Answer:

After the transfer the pressure inside the 20 L vessel is 0.6 atm.

Explanation:

Considering O2 as an ideal gas, it is at an initial state (1) with V1 = 3L and P1 = 4 atm. And a final state (2) with V2 = 20L. The temperature remain constant at all the process, thus here applies the Boyle-Mariotte law. This law establishes that at a constant temperature an ideal gas the relationship between pressure and volume remain constant at all time:

$P x V = k$

Therefore, for this problem the step by step explanation is:

$P_{1} xV_{1} = P_{2} xV_{2}$

Clearing P2 and replacing

$P_{2}= \frac{P_{1} xV_{1}}{V_{2} } = \frac{4atmx3L}{20L} = 0.6atm$

(Please help, ASAP) How many grams are in 3.45x10^23 atoms of P?

Daniel [21]

one mole of P weights about 31 grams

in one mole there are 6.022*10^23 atoms

we use the rule of threes

6.022*10^23atoms......weight..........31 grams

3.45*10^23 atoms.........weight...........x grams

x=(3.45*10^23*31)/6.022*10^23

x=106.95/6.022=<u><em>17.76 grams</em></u>
