Answer:
Transcribed image text: A lake has a surface area of 12.9 square miles and an average depth of 32.6 feet. What is its
In the reaction we gives the magnesium chloride and released hydrogen gas.
The reaction is carried out by contaning positive and negative charged on elements as follows
Mg + HCl --->MgCl2 + H2
Net reaction gives
Mg+ + 2Cl- + 2H+---> Mg+² + 2Cl- + 2H
Check it Mg(s) and Mg2+ not equal . The donor is element while the acceptor is an ion. The same process is done for H2 (g) and H+.
At standard temperature and pressure, the volume of 58 gms of chlorine gas is 7.08 L.
<h3>What is STP?</h3>
STP is the condition of the ideal gas that relates to the moles, pressure, temperature, and volume. The ideal gas law at the STP is given as:
PV = nRT
Given at STP,
Pressure (P) = 1 atm
Temperature (T) = 273 K
Gas constant (R) = 0.0821 L atm/ mol K
Moles (n) of chlorine gas is calculated as:
Moles = Mass / Molar mass
n = 58.0 / 70.90
= 0.818 moles
The volume for the ideal gas equation is calculated as:
V = n * R * T / P
V = 7.08 / 1
V = 7.08 L
Therefore, at STP the volume of the gas is 7.08 L.

Draw an arrow from outside the cell (where there is only 1 water molecule) to inside that circle. Then color the water molecules that are labeled h2o:)
