Answer:
2542
Rule for multiplying Significant Figures:
- The product is limited to the number of sig figs equal to the least number of sig figs in the problem
Explanation:
52.733 has 5 significant figures and 48.21 has 4 significant figures. Therefore, the answer given must have 4 significant figures.
52.733(48.21) = 2542.25793
This answer round to have 4 significant figures is 2542.
The correct option is C.
Finance charge on credit card refers to the interest you pay for borrowing money when you are using a credit card. It is the interest you are charged on the debts you owe and sometimes it might include other charges such as penalty fees for late payment. Individual finance charge is usually calculated using the the person APR [Annual Percentage Rate], amount of debt owe and the time period been considered. The higher your debts, the higher your finance charge.
Answer: Gamma Rays
Explanation:
The waves with the highest frequency are Gamma Rays. These electromagnetic waves travel at a very high speed. Best of Luck to you!
Answer:
The gases and particles of earths atmosphere scatter sunlight in different directions making the sky a specific color. Since blue light travels shorter, smaller waves its scattered more than others.
The balanced equation for the reaction is as follows;
2H₂S + SO₂ —> 2H₂O + 3S
Stoichiometry of H₂S to SO₂ is 2:1
Limiting reactant is fully used up in the reaction and amount of product formed depends on amount of limiting reactant present.
Number of H₂S moles - 8.0 g / 34 g/mol = 0.24 mol of H₂S
Number of SO₂ moles = 12.0 g / 64 g/mol = 0.188 mol of SO₂
According to molar ratio of 2:1
If we assume H₂S to be the limiting reactant
2 mol of H₂S reacts with 1 mol of SO₂
Therefore 0.24 mol of H₂S requires - 1/2 x 0.24 = 0.12 mol of SO₂
But 0.188 mol of SO₂ is present therefore SO₂ is in excess and H₂S is the limiting reactant.
H₂S is the limiting reactant
Amount of S produced depends on amount of H₂S present
Stoichiometry of H₂S to S is 2:3
2 mol of H₂S forms 3 mol of S
Therefore 0.24 mol of H₂S forms - 3/2 x 0.24 mol = 0.36 mol of S
Mass of S produced = 0.36 mol x 32 g/mol = 11.5 g of S is produced
