HELP, HELP! WILL MARK BRAINLIEST 55 kernels of popcorn have a mass of 6.0 g before popping and 4.5 g after popping.

3.)Calculate the average mass of 1 kernel of unpopped popcorn.

4.) Calculate the average mass of water lost from 1 kernel of popped popcorn.

5.) How many water molecules are lost from an average kernel of popcorn? HELP PLEASE

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
