The oxidation of oxygen in peroxides is?
-1
Peroxides include hydrogen peroxide, H2O2. This is an electrically neutral compound and so the sum of the oxidation states of the hydrogen and oxygen must be zero.
National University of Science and Technology NUST is top rated engineering university of Pakistan. NUST was founded in 1991 with an aim of providing quality education to the students. NUST grow up dramatically in a very little time period because of their focus towards quality education and dedication toward their work.

What shunt resistance must be connected across a galvanometer of 50.0 ohm resistance which gives full scale deflection with 2.0MA current so as to convert it into an ammeter of range 10.0A?
0.01Ω
In fish, gills surface is ventilated by constant flow of?
Water
Marine species obtain oxygen dissolve in water so gills are constantly ventilated by water to oxygenate the blood.
Some reaction start very slow, but then gain speed and eventually become very fast. These reactions exhibit which phenomena?
Auto catalysis
In these reaction product formed acts as a catalyst. That is why they start very slow, but then gain speed (as the product catalyst is available) and eventually become very fast.
Value of cos (tan-1 15/8 – sin-1 7/25) =?
297/425
Find the work done in moving a charged particle of 3 micro columb from infinity to a distance of 0.04m to another charged particle of 5 micro columb?
3.4 J
Trypsinogin is converted into trypsin by the activity of:
Enteropeptidase
Trypsinogen is the precursor form of the pancreatic enzyme trypsin. It is found in pancreatic juice, along with amylase, lipase and chymotrypsinogen. It is activated by enteropeptidase, which is found in the intestinal mucosa, to form trypsin. Once activated, the trypsin can activate more trypsinogen into trypsin. Trypsin cleaves the peptide bond on the carboxyl side of basic amino acids such as arginine and lysine.
