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
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
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.
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
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 ...
