How would I Determine the number of moles in 3.51 x 10^23 formula units of CaCl2
Andrej [43]

Answer:

by using this formula you will get it

Explanation:

number of mole = number of particles÷ Avogadro's number

n=3.51×10^23÷ 6.02×10^23

n = 0.58 moles

How many grams of NaF form when .508 mol of HF react with excess Na2SiO3?
jonny [76]
2HF + Na2SiO3 ---->  2NaF +  H2SiO3   is the balanced equation.

2 moles of HF  form 2 moles of NaF

therefore 0.508 Mol  HF forms 0.508 mol of NaF

In grams this is 0.508( rel atomic mass of Na + RAM of F)
                        = 0.508 (22.99+19)
                        =  21.33 grams

The following reaction has been reported in the chemical literature and gives a single organic product in high yield. Write the
Alla [95]

Answer:

Explanation:

The principle applied is the Markovnikoff's rule which states that when hydrogen chloride adds to a double bond, the hydrogen atoms join to the carbon that already has the most hydrogen atoms bonded to it. The rule wa postulated by a russian chemist known as Vladimir Markovnikoff.

In the markovnikoff's rule, there are sveral conditions that must be met, one of them is that no free radicals must be involved.

The reaction and the structure of the product is as shown in the attachment.

A sample of gas is held at 1000C at a volume of 20 L. If the volume is increased to 40 L, what is the new temperature of the gas
kaheart [24]

Answer:

The new temperature will be 2546 K or 2273 °C

Explanation:

Step 1: Data given

The initial temperature = 1000 °C =1273 K

The volume = 20L

The volume increases to 40 L

Step 2: Calculate the new temperature

V1/T1 = V2/T2

⇒with V1 = the initial volume = 20L

⇒with T1 = the initial temperature = 1273 K

⇒with V2 = the increased volume = 40L

⇒with T2 = the new temperature = TO BE DETERMINED

20L/ 1273 K = 40L / T2

T2 = 40L / (20L/1273K)

T2 = 2546 K

The new temperature will be 2546 K

This is 2546-273 = 2273 °C

Since the volume is doubled, the temperature is doubled as well

How many moles of sulfur are present in 5 moles of h2so4?.
dusya [7]

Answer:

One mole of sulfuric acid consists of one mole of sulphur.

Explanation:

This is because  in the molecule of sulfuric acid there is  only one atom of sulphur that is present. As a result of this since in case of one mole of sulfuric acid there should be only one 1 mole of sulphur.

According to the molar concept one mole of sulphur means 6.023 x10^ 23 atoms of sulphur is present in one complete mole of sulfuric acid. in addition to this the molecule also consists of 2 moles of hydrogen and 4 moles of oxygen in 1 mole of sulfuric acid

to know more about sulfuric acid,

. Calculate the mass (in g) of 0.500 mol of sulfuric acid (H2SO4 ...
