Answer:
Below are some general properties of these (HCl and H2SO4) solutions, and their common behavior in terms of the species present.
Explanation:
1) Aqueous solutions of these acids have a sour taste. i.e they can destroy body tissue and materials.
2) Both acids react with active metals and release hydrogen gas, H2.
Recall, in terms of an activity series. Metals above hydrogen in the series undergo displacement reactions with these acids. For example
2Na + 2HCl ------- 2NaCl + H2
and 2Na + H2SO4 ------- Na2SO4 + H2
3) The acids will react with bases to produce salts and water. These are neutralization reaction
s and the products are water and an ionic compound called a salt. For example
NaOH + HCl --------- NaCl + H2O
2NaOH + H2SO4 ---------- Na2SO4 + 2H2O
The question is: WHAT DATA OF THE ELECTRONIC CONFIGURATION ALLOWS YOU TO LOCATE THE CHEMICAL ELEMENTS IN THE PERIODIC TABLE?
Explanation:
Elements which have same number of valence electrons tend to show similar chemical properties due to which they are placed in the same group.
Hence, electronic configuration of an element tells us the number of valence electrons present in an element. As a result, it becomes easy to locate the element in its respective group.
Answer:
C11H25SO4
Explanation:
The total mass of the compound is 253.4 g, so, the mass of each element will be:
C: 52.14% of 253.4 = 0.5214x253.4 = 132.12 g
H: 9.946% of 253.4 = 0.09946x253.4 = 25.20 g
S: 12.66% of 253.4 = 0.1266x253.4 = 32.08 g
O: 25.26% of 253.4 = 0.2526x253.4 = 64.00 g
The molar mass are: C = 12 g/mol, H 1 g/mol, S = 32 g/mol, and O = 16 g/mol
So, to know how much moles will be, just divide the mass calculated above for the molar mass:
C: 132.12/12 = 11 moles
H: 25.20/ 1 = 25 moles
S: 32.08/32 = 1 mol
O: 64.00/16 = 4 moles
So the molecular formula is C11H25SO4
Answer:
D. As water flows through the channels toward the turbines, it has kinetic energy. This is changed to mechanical energy as the water turns the turbines. Then the mechanical energy of the turbines is changed to electrical energy by the generator.
