i need help with a packet that im struggling with my questions are
write the total number of atoms present for the following questions:
a. 4SO2 now i tried and got 8O'S and 1S
b. 8O2 i tried and got 16 all together
c. 3Al2(SO4)3 i tried and got 6Al, 3S, and 12O
my next question is one way to test salinity of a water sample is to add a few drops of silver nitrate solution with a known concentration. as the solutions of sodium chloride and silver nitrate mix, a precipitate of silver chloride forms, and sodium nitrate is left in solution. translate these sentences into a balanced chemical equation.
now i don't understand it but i tried some of it i just don't know where to put it at in the sentence but i know in the question i would need NaCl, Ag (NO3) and i know i need plus signs and a yield sign but i just don't know where everything goes or how to set it up can u help me
now i have to balance an equation and from that answer i have to translate it into a chemical equation my question is NaHCO3(S)=Na2CO3(S)+H2O(g)+CO2(g) now i tried the problem and got 2NaHCO3(S)=Na2CO3(s)+CO2(g)+H2O(g) and after that i have to translate it into a chemical equation but i don't know if my answer is correct to translate it
Sure! I can help you with all of your questions.
1. To find the total number of atoms present in a chemical formula, you need to multiply the subscript of each element by the number of molecules or ions present in the formula. In this case:
a. 4SO2: Each SO2 molecule contains 1 sulfur atom (S) and 2 oxygen atoms (O). Multiply this by the total number of molecules (4) to get: 4 x (1S + 2O) = 4S + 8O.
b. 8O2: Each O2 molecule contains 2 oxygen atoms. Multiply this by the total number of molecules (8) to get: 8 x 2O = 16O.
c. 3Al2(SO4)3: Each Al2(SO4)3 formula unit contains 6 oxygen atoms, 3 sulfur atoms, and 6 aluminum atoms. Multiply each element by its respective subscript and then by the total number of formula units (3) to get: 3 x (6Al + 3S + 12O) = 18Al + 9S + 36O.
2. To translate the sentences into a balanced chemical equation, you need to represent the reactants and products using their chemical formulas and balance the equation by ensuring that the number of atoms is the same on both sides. In this case, the sentence states that sodium chloride (NaCl) and silver nitrate (AgNO3) react to form silver chloride (AgCl) and sodium nitrate (NaNO3). Here's the balanced chemical equation:
NaCl + AgNO3 ā AgCl + NaNO3
3. To balance the equation NaHCO3(S) = Na2CO3(S) + H2O(g) + CO2(g), you need to ensure that the number of atoms is the same on both sides. Your attempt of 2NaHCO3(S) = Na2CO3(s) + CO2(g) + H2O(g) is close, but it can be improved. The balanced equation is:
2NaHCO3(s) ā Na2CO3(s) + H2O(g) + CO2(g)
Now, to translate the equation into a chemical equation, you simply need to write the names of the reactants and products. Here's the chemical equation:
Sodium bicarbonate (solid) ā Sodium carbonate (solid) + Water (gas) + Carbon dioxide (gas)
I hope this helps! Let me know if you have any more questions.
