1. Iodic acid, HIO3, can be prepared by reacting iodine, I2, with concentrated nitric
acid. The skeleton equation is:
I2(s) + NO3
-
(aq) → IO3
-
(aq) + NO2(g). Balance this equation using the half reaction method.
u+v =3,4 and u ➖ v=1, ➖ 2 then find v and u
what is probability
Suppose a random sample of 38 sports cars has an average annual fuel cost of K2218 and the standard deviation was K523. Construct a 90% confidence interval for μ. Assume the annual fuel costs are normally distributed.

A proton beam through a region of space where the magnetic field is a uniform value of 5.0 T directed along the positive z-axis. The protons have a velocity of magnitude 4.0 x 10⁵ m/s in the xz plane at an angle of 30° to the positive z-axis. Find the force on the portion
The critical angle for material C is 570. If an incident ray approaches the boundary between material C and the air at 590, the refracted ray will lie along the boundary between the material.
How many moles present in 23.3 Kg Ar ?
3 A random of sample of size 25 is taken with replacement from a population with 121.4 and 50.5. 4. A random sample of 20 independent observations is taken from a population with p = 23.8 and a = 5.
