Answer:
As you go down the periodic table, usually atoms get bigger because n gets bigger (there are electrons in higher shells). Effective nuclear charge does get bigger too going down the periodic table, but this effect is smaller than the change in shell.

Answer:
Physical properties are used to observe and describe matter. Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.
Explanation:
The answer to this question is A
We are given the pOH of the solution of 10.75. pOH is the property of the solution that is related to the OH ion concentration of the solution. THe formula to be followed is pOH = -log (OH); OH- = 10^-pOH. In this case, OH- = 10^-10.75 equal to B. 1.778 x 10^-11 M
NH4 itself is called ammonium ion with positive charge of 1+. hence the oxidation state will be +1
OH itself is called hydroxide ion with negative charge of 1-. hence the oxidation state will be -1
there's actually no such compound as stated in your chemical formula. although it's simply called ammonium hydroxide by looking at the chemical formula, in fact the compound should rightly be called as aqueous ammonia with chemical formula of NH3 (aq). this is because the ammonia molecule will ionise due to the presence of water molecule to be protonated, hence forming ammonium ion and hydroxide ion in the solution.
