What is the total pressure exerted by a mixture containing two gases if the partial pressure of one gas is 70 kPa and the partial pressure of the other gas is 30 kPa?

Answer:Demagnetizing a magnet is also possible. Only a few substances are ferromagnetic; the most common ones are iron, cobalt and nickel and their alloys. The rare-earth metals neodymium and samarium are less common examples.

Total mass of carbon must be decreasing in different step of carbon cycle because matter is conserved in the processes and reactions of carbon cycle. Carbon is a matter and it is the major constituent of living organisms.

Carbon cycle refers to processes where carbon move from the atmosphere to the biosphere and Earth and then back to the atmosphere.

It involves processes of using and reusing carbon again and again and it's conservation.

Carbon is an organic matter found in living organisms and total mass of carbon reduces because it is a matter that is conserved.

Carbon is released from that atmosphere, use for photosynthesis, plants and animals consume the plants. They defecate , respirate and carbondioxide is released during respiration.

Therefore,Total mass of carbon must be decreasing in different step of carbon cycle because because matter is conserved in the processes and reactions of carbon cycle. Carbon is a matter and it is the major constituent of living organisms.

Db

Dubnium/Symbol

Explanation:

please mark my answer in brainlist plz

Answer:

DbCl5

Explanation

Dubnium has 2 electron in 7s orbital and 3 electron in 6d orbital. Because Dubnium is synthetically produced with atomic number of 105, it is highly radioactive and quickly decay. Like other transition, it can have different oxidation state and it is assumed that dubnium have +3,+4,+5 oxidation state number(that most likely involves electron from 6d orbital). Hence chloride ions with -1 oxidation number would react to form Dubnium Chloride as DbCl3, DbCl4, and DbCl5. Now it is highly unlikely these compounds can really be formed. However if you read nature chemistry article https://www.nature.com/articles/nchem.2610, there is mention that DbCl5, DbBr5, and DbOCl3 may be expected to form.

Answer:

empirical formula

Answer:

1. How many moles of oxygen will occupy a volume of 2.5 liters at 1.2 atm and 25° C? PV = V (1.2 n. 0821) (298) = 123 mols 2.

2.0 moles of oxygen gas will occupy a volume of 6.67 L at the same temperature and pressure.

Moles is a unit of measurement used in chemistry to express the amount of a substance. It is a counting unit that represents the number of particles, such as atoms, molecules, or ions, in a given sample.

One mole of a substance is defined as the amount of that substance that contains Avogadro's number of particles, which is approximately 6.022 x 10²³. This number is based on the concept that atoms, molecules, and ions are extremely small and difficult to count individually, so using moles allows for a more practical and convenient representation of quantities.

Given:

Moles of oxygen gas (initial) = 0.45 mol

Volume of oxygen gas (initial) = 1.5 L

Moles of oxygen gas (final) = 2.0 mol

Volume of oxygen gas (final) = ?

Using the principle of molar volume, we can set up the following ratio:

(0.45 mol / 1.5 L) = (2.0 mol / V)

V = (1.5 L × 2.0 mol) / 0.45 mol

V = 6.67 L

Answer:

448mL AgNO3

Explanation:

M x V

n = 0.230 x .045 = 0.01

2AgNO3 + Na2S --> Ag2S+2NaNO3

1 mol Ag2S --> 2 moles AgNO3

.01 mol Ag2S --> ? moles AgNO3

.01x2/1=.02 moles AgNO3

Moles to L conversion is multiplying by 22.4L so we do .02 x 22.4=0.448L

Then we convert to mL so we multiply by 1000 (1000 x 0.448)

448mL AgNO3

Answer:

Volume = 35.3L

Explanation:

Use Ideal Gas Law (PV=nRT) and isolate for V (volume) by dividing both sides by P (pressure). You will then get the eqaution listed below and you can solve by using the method I used below.

V = nRT/P

V = (0.75kPa)(8.314)(298K)/(52.7kPa)

V = 1858.179/52.7

V = 35.3L
