Answer:
47.01 g/mol is molar mass
Answer:
C8H18(g) + 12.5O2(g) -> __8__CO2(g) + 9H2O(g) + heat
CH4(g) + _2___O2(g) -> ____CO2(g) + _2___H2O(g) + heat
C3H8(g) + _5___O2(g) -> _3___CO2(g) + __4__H2O(g) + heat
2C6H6(g) + __15__O2(g) -> __12__CO2(g) + __6__H2O(g) + heat

Answer:
The correct option is C.
Solutions with low pH values have sour taste.
Explanation:
Low pH value show acidic property which can be define as , -log of conc. of hydrogen ion.
Acid has following properties
- Sour taste
- Turn blue litmus into red
- corrosive
-OH group: Base have OH groups. So it is not correct option so it not correct for low pH i.e. acid
turns litmus paper blue: Base turn red litmus into blue, so it not correct for low pH i.e. acid
feels slippery: Bases are mostly slippery like soap
tastes sour: Sour taste is for acid and bitter taste is for base. So it is correct option for acid
