First, calculating the amount of zinc carbonate by multiplying the given mass of the ore by the percent zinc carbonate.
mass of zinc carbonate = (976 tons)(0.78)
= 761.28 tons
Then, calculate for %Zn in zinc carbonate
%Zn = ((65.38) / (125.39)) x 100%
% Zn = 52.141%
tons of Zn from the sample,
mass of Zn = (761.28 tons)(0.52141)
= 396.94 tons Zn
The characteristic of water that is responsible for frost wedging is that it expands as it freezes and is denoted as option A.
<h3>What is Frost wedging?</h3>
This is referred to a type of physical weathering which is characterized by rocks being broken down into smaller particles through the freezing and thawing process.
This is possible because water is known to expand as it freezes thereby resulting in the expansion of the rocks which forms cracks as a result of frequent freezing and thawing processes.
This is therefore the most appropriate characteristic of water which makes it possible for frost wedging to take place.

Conception occurs when a sperm from a man fertilizes an egg from a woman. This fertilization occurs in the woman's fallopian tubes, not in her va..gina or u..terus.
Answer: B
Explanation: concentratio = amoiunt of moles / volume
n = c/V = 0.27 mol / 0.30 l = 0.900 M
Answer:
F has the smallest atomic radius.
Explanation:
Atomic radius is one of the perIodic properties defined by the Periodic Table.
Atomich radius is the distance to the nucleus that comprises 95 % of the density electronic load. It can be defined as a function of the internuclear distance. Although this distance varies, depending on whether the atoms are linked by a chemical bond or simply in contact without forming link.
Atomic radius is a periodic property that increases by period (from the top to below) and decreases (from left to right) by group.
In the same group are O and F, so F < O
In the same group, we have S and Cl, so Cl < S
As Cl and F are in the same period, we define the atomic radius Cl > F and
S > Cl (In the same period)
The right way to order the elements are S > Cl > O > F
