Answer:
Explanation:
We're given the following ions:
Hydrogen sulfide is a weak acid, so it only ionizes to ions to a very low extent. This means we would expect to see it in a molecular form in a net ionic equation rather than a dissociated form (hydrogen cations and sulfide anions). In each of these net ionic equations, we expect the three cations to displace hydrogen from hydrogen sulfide and form three precipitates.
Firstly, iron(II) displaces hydrogen forming iron(II) sulfide and acidic conditions:
Secondly, chromium(III) cation displaces hydrogen forming chromium(III) sulfide:
Thirdly, nickel(II) cation displaces hydrogen forming nickel sulfide:
Answer:
Explanation:
Base your answer to the question on the information below and on your knowledge of chemistry. At 1023 K and 1 atm, a 3.00-gram sample of SnO2(s) (gram formula mass = 151 g/mol) reacts with hydrogen gas to produce tin and water, as shown in the balanced equation below. SnO2(s) + 2H2(g) → Sn(L) + 2H2O(g) Show a numerical setup for calculating the number of moles of SnO2(s) in the 3.00-gram sample.
Grams to Atoms Calculator is a free online tool that displays the conversion from grams to atoms for the particle. BYJU’S online grams to atoms calculator tool makes the conversion faster and it displays the conversion to atoms in a fraction of seconds.

The procedure to use the grams to atoms calculator is as follows:
Step 1: Enter the atomic mass number, grams and x in the respective input field
Step 2: Now click the button “Calculate x” to get the output
Step 3: Finally, the conversion from grams to atoms will be displayed in the output field
How to Convert Grams to Atoms?
The conversion of particles from grams to atoms can be determined as below:
Suppose you have 10 gram of carbon. Now, it should be converted in terms of atoms.
We know that the molar mass of 1 mole of carbon is equal to 12. It means that 12 grams per mole
Also, the Avogadro constant is 6.02 x 1023
So, the conversion of carbon from grams to atoms is given by
= 10(1/12)( 6.02 x 1023)
= 5.02 x 1023
Therefore, 10 grams of carbon is equal to 5.02 x 1023 atoms
