If two compounds chemically react together and upon interchanging their elements with each other is known as a double displacement reaction.
For example,
In this reaction, OH in is replaced by Cl of HCl. As a result, is formed.
Therefore, the statement when calcium hydroxide powder is placed into a hydrochloric acid solution, aqueous calcium chloride and water are formed, is true.
<span>Answer: yes, when calcium hydroxide powder is placed into a hydrochloric acid solution, aqueous calcium hydroxide and water are formed. </span> <span /><span /><span> Explanation:
</span><span>1) Calcium hydroxide is a base whose chemical formula is: Ca(OH)₂</span> <span /><span> 2) Hydrochloric acid is the acid with chemical formula HCl
</span><span>3) Acids and bases react in a double replacement reaction forming salt plus water: Acid + Base → salt + water </span> <span /><span /><span> 4) The specific chemical equation for these reactants is:
</span><span>Ca(OH)₂ (s) + 2HCl(aq) → CaCl₂ (aq) + 2H₂O(l)</span> <span /><span> </span><span>5) CaCl₂ is calcium chloride, a salt, and H₂O is water </span><span> </span>
The heat source for our planet is the sun. Energy from the sun is transferred through space and through the earth's atmosphere to the earth's surface. Since this energy warms the earth's surface and atmosphere, some of it is or becomes heat energy. There are three ways heat is transferred into and through the atmosphere:
The Ph value for Pro will be neutral and neutral charge on the Ser. Molecules of atoms generally have neutral electrical charge. If the overall charge of a peptide is negative then it is considered as negative. Pro and Ser amino acids have neutral Ph values.
