Answer:
A calorimeter is an apparatus for measuring the amount of heat involved in a chemical reaction or other process.
Answer:
0.0970 M
Explanation:
Remember this equation:
mol/M x V
Convert it so that you can get M.
M=mol/V
Convert the 2.14 grams of H2SO4 into mols
=0.0218
Convert mL to L
225/1000
=0.225
Plug it in.
0.0218/0.225
=0.0970 M
Answer:
Coefficient: number balancing sulfuric acid in a chemical reaction.
Subscripts: number of atoms of each element forming the compound.
Explanation:
Hello!
In this case, since sulfuric acid is a molecule containing hydrogen, sulfur and oxygen in the following way:
- Two hydrogen atoms.
- One sulfur atom.
- Four oxygen atoms.
We can notice the 2 at H represents those two hydrogen atoms, the subscriptless S represent that 1 sulfur atom and the 4 at O represents those four oxygen atoms.
Moreover, since the molecules is given as 7 H2SO4
; from stoichiometry, we infer that every number preceding the molecule stands for a coefficient which is used to balance a undergoing chemical reaction reaction.
Best regards!
Answer : The number of servings of this potato chips eaten to consume 0.0230 moles of NaCl must be, 5.39
Explanation :
First we have to calculate the moles of NaCl.
Now we have to calculate the number of servings.
As, the number of serving in 0.004269 moles of NaCl = 1 serving
So, the number of serving in 0.0230 moles of NaCl = 
serving
Thus, the number of servings of this potato chips eaten to consume 0.0230 moles of NaCl must be, 5.39
