#1 is 95L balanced . #2 is 55^3G balanced.
Molar mass KCl = <span>74.5513 g/mol
Number of moles:
21.9 / 74.5513 => 0.293 moles
Volume = 869 mL / 1000 => 0.869 L
Molarity = moles / Volume
Molarity = 0.293 / 0.869
=> 0.337 M</span>
Ferromagnesian silicate minerals (i looked it up)
Yes, Fe(s)+CuSO4→FeSO4(aq)+Cu(s) is a redox reaction. The reducing agent is Fe(s), while the oxidizing agent is CuSO4.
<h3>Oxidation-reduction reaction (redox)</h3>
Oxidation-reduction reaction is the type of reaction in which electrons are transferred from one element to another. A compound or an element either gains are looses an electron in redox reactions.
Fe(s)+CuSO4→FeSO4(aq)+Cu(s)
From the equation above, Fe(s) is the reducing agent because it gives away 2 electrons and undergoes oxidation reaction.
From the equation above, CuSO4 is an oxidizing agent because it gives oxygen to Fe(s) and undergoes a reduction reaction.
Therefore, the reducing agent is Fe(s), while the oxidizing agent is CuSO4.

Answer:
B. Temperature
Explanation:
A thermometer is a device used to measure temperature. Temperature is the average kinetic energy of a material's molecules or its average thermal energy. Heat is transferred to the thermometer, causing changes in its physical properties.
