YES
The number of protons. Carbon = a Z number of 6. Hydrogen = a Z number of 1 Oxygen = a Z number of 8. And so on. Just read it off the periodic table.
Not a singular "Z", but there are two: Zn- Zinc Zr- Zirconium.
The solvent is the water (chemical formula H2O). The solute is the salt (table salt, NaCl or another substance).
The solubility table is used to predict whether a given solute will dissolve in a particular solvent at a specific temperature. It provides information on the maximum amount of solute that can dissolve in a solvent under those conditions.
There are two on the Periodic Table of Elements, both transition metals: Zinc, number 30 and Zirconium, number 40.
NO
Yes
If the value given in the table for Z = z is k: that is, pr(Z > z) is 1 - k, then the two-tailed probability of observing a value which is at least as extreme, ie Pr(|Z| > z) is 0.5*(1-k).
The solute is the extract of maples and the solvent is water.
See the attached link. The area that is read from the table is 1 - .9066 or .0934. Go to the body of the table for the value .0934 and the answer is -1.32. Therefore Z = -1.32.

yes because the thing that you dissolve it in is the solvent
The solvent is the water (chemical formula H2O). The solute is the salt (table salt, NaCl or another substance).
From the table in the related link, the value at z equal one is 0.3413. The area then to the right of z equal one is 0.5 - 0.3413, or 0.1587.
Assume the z-score is relative to zero score. In simple terms, assume that we have 0 < z < z0, where z0 is the arbitrary value. Then, a negative z-score can be greater than a positive z-score (yes). How? Determine the probability of P(-2 < z < 0) and P(0 < z < 1). Then, by checking the z-value table, you should get: P(-2 < z < 0) ≈ 0.47725 P(0 < z < 1) ≈ 0.341345

Table salt or sodium chloride is indeed a solute. It will dissolve and disperse in water. In that context, water is a solvent.
