Whoever answers this ill give brainliest! PLS ANSWER QUICK AHH! You are titrating a 125 mL sample of KOH solution; the pH meter reads 7.00 after the addition of 84.7 mL of 0.750 M HNO3.

What is the concentration of the KOH solution?

A. 0.125 M KOH
B.0.750 M KOH
C.0.508 M KOH
D. 0.0635 M KOH

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

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.
