C3H8 + O2 --> CO2(g) + H2O(g) + energy(heat)
butane + oxygen --> carbon dioxide + water + heat
Neon is an element and elements are pure oxygen is. Or it is a gas
2.565L
Explanation:
- Charles law states that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature.V/T=K
V1/T1=V2/T2
Unit of Kelvin = 273.15
- To get the absolute temperature, we need to convert the degree celsius temperature to kelvin.
T1= 22+273.15= 295.15 K
T2 = 71+273.15= 344.15 K
V1 = 2.20 L
V2 =?
2.20/295.15=V2/344.15
0.00745 x 344.15 = 2.565 L
Hence, 2.565 L is the new volume of the balloon.
Answer:
Number of peptide fragments resulting from cleaving with cyanogen bromide? A: Three peptide fragments
Number of peptide fragments resulting from cleaving with trypsin? A: Four peptide fragments
Which of these reagents gives the smallest single fragment (in number of amino acid residues)? A: CnBr, a dipeptide fragment consisting of AL (Alanine-Leucine)
Explanation:
Cyanogen bromide cleaves the methionine C-terminus, then we have a first fragment of 8 amino acids: DSRLSKTM, a second fragment of 15 aas YSIEAPAKLDWEQNM, and a last fragment of only 2 aas is produced, AL
Trypsin cuts the C-terminus of Arginine and Lysine, then we'll have a first fragment of 3 aas DSR, a second fragment consisting of also 3 aas LSK, a third fragment of 10 aas TMYSIEAPAK, and a last fragment of 9 aas LDWEQNMAL. All produced in three cut sites.
