Answer:
1.16L can be made
Explanation:
Molarity = Mol / Volume
Volume = Mol / Molarity
Let's determine the moles of salt, with that mass:
130 g FeCl₂ . 1mol / 126.75 g = 1.02 moles of FeCl₂
Volume = 1.02 mol / 0.88 mol/L → 1.16L
Answer:
Molecules in the gas move faster due to the fact they have more energy
Explanation:
If you put more heat the higher the volume will be. Less heat means less volume.

Answer:
chemical
Explanation:
A chemical change is irreversible and leads to the formation of new products.
Rusting occurs as a result of an irreversible chemical reaction between iron, oxygen and moisture. Rusting is the oxidation of iron when exposed to oxygen and moisture.
The rusting of iron is an electrochemical process in which water serves as the electrolyte and iron serves as the anode. The rusting of iron leads to the formation of hydrated iron III oxide (rust) usually seen an brown flakes that surround a rusted iron material.
Answer:
d. changing temperature
Explanation:
The thermodynamic equilibrium constant K is defined as a quantity characterizing the equilibrium of a chemical reaction. For a reaction where concentrations are in equilibrium:
aA + bB ⇄ cC + dD
The equilibrium constant is:
Thus, the equilibrium constant will change if:
a. Varying the initial concentration of reactants
. FALSE. The k constant doesn't depend of initial concentrations but concentration in equilibrium does.
b. Adding other substances that do not react with any of thespecies involved in the equilibrium
. FALSE. The equilibrium constant just depends of substances that are involved in the equilibrium
c. Varying the initial concentration of products
. FALSE. Again, equilibrium constant doesn't depend of initial concentrations.
d. Changing temperature
. <em>TRUE. </em>As a thermodynamic constant, k depends of temperature thus:
e. Changing the volume of the reaction vessel. FALSE. The changing in the volume of the reaction vessel will change just the initial concentrations of the reactants.
