Answer:
strontium oxide + hydrochloric acid (HCL) = strontium chloride
Answer:
<h2>2. H2O < CH3OH < CH3CH2OH < C9H20</h2>
Explanation:
Decane is a hydrocarbon so it is a non-polar molecule. Non-polar molecules are soluble in non-polar molecules and polar molecules are soluble in polar molecules. Water is a polar molecule so it is least soluble in decane molecule and
is a non-polar molecule so it is most soluble in decane molecule. Methanol and ethanol are the derivatives of hydrocarbon so they have more solubility than water but less solubility than nonane molecules.
Answer: A. Refrigerator technology has helped improve people’s nutrition.
Explanation:
The element that has been reduced in the chemical equation is
.
The given reaction has been:

The reaction has been the redox reaction, in which the one of the reactant has been oxidized, and the other has been reduced in the chemical reaction.
<h3>Reduction in the reaction</h3>
The reduction has been defined as the gain of electrons. In the given reaction, the Mg loses 2 electrons and has been converted to the Mg ion.
Thus, Mg has been oxidized in the reaction.
The Cl has been present as the diatomic molecule and with the gain of two electrons from the Mg it has been converted to two chloride ions.
Thus, the element that has been reduced in the chemical equation is
.
