Answer:
Al
Explanation:
The reduction potentials of the metals are
Al= -1.66
Zn= -0.76
Cu= +0.34
Pb= -0.13
Hence All has the most negative reduction potential and is the most reducing element among all the elements listed.
Answer:
Rivers were attractive locations for the first civilizations because they provided a steady supply of drinking water and made the land fertile for growing crops. Moreover, goods and people could be transported easily, and the people in these civilizations could fish and hunt the animals that came to drink water.Rivers were attractive locations for the first civilizations because they provided a steady supply of drinking water and made the land fertile for growing crops.

Explanation:
Molar mass Argon = <span>39.948 g/mol
number of moles = mass solute / molar mass
n = 150 / </span><span>39.948
n = 3.7548 moles
hope this helps!</span>
Stoichiometry:
First, calculate the number of grams for one mole of Ca3 (PO3)4
(3 * (Mass of Ca)) + (4 * (Mass of P + (3 * Mass of Oxygen)))
= (3*40.08) + 4(30.97 + (3*16.00))
=(120.24) + 4(78.97)
=436.12 g / mol Ca3(PO3)4
This means there are 436.12 g per 1 mole of Ca(PO3)4. Since there are 4.50 moles of Calcium Phosphate, mulitply the molar mass of Ca(PO3)4 by 4.50 and you should get 1962.54 g. Since there are 3 sigfigs, the final answer is 1960 g.
on a side note: I put in all my work in case 1. your periodic table if different, 2. my work is wrong, 3. you put in the question wrong because I feel that the actual compound would be Ca3(PO4)3 instead of Ca3(PO3)4 (if this is the case, the answer should be 1820 g).
The appropriate response is Aluminum. It has higher in the movement arrangement than a nickel. Aluminum metal is so artificially responsive that local examples are uncommon and constrained to outrageous decreasing conditions. Rather, it is discovered joined in more than 270 unique minerals.
