Answer:
I)Acetylene
II)2-Methyl-1-butanol
Explanation:
I)appears as a colorless gas with a faint garlic-like odor. Easily ignited and burns with a sooty flame. Gas is lighter than air.
Answer:
mixture is amino acid, peptides, carbohydrates and other simple organic compounds can be separated by paper chromatography.
The heat needed to raise the temperature of 50g of substance by 15 c is calculated as follows
Heat = mc delta T
m= mass (50g)
c= specific heat capacity (0.92)
delta T= change in temperature( 15 c)
heat is therefore= 50 x 0.92 x 15 = 690
Nb: my answer has no units since the given specific heat capacity has no units
Answer:
V= 10.2L
Explanation:
NB , n= m/M= CV
Molar mass of NaOH= 40gmol-1
15.3/40= 0.0375×V
Simplify
V= 10.2L
