Answer: option A
Explanation: Organic chemistry deals with the study of carbon and hydrogen containing compounds, drugs and pharmaceuticals etc.
A chemical change is defined as something that changes the substance of something (such as the creation of water from hydrogen and water), and can be figured out if chemical or physical based on different changes and properties. Your answer will be D because these are two different elements (compounds in case of CO2) that combine to form a different substance, thus changing the identity of the substance.
The precise shape of a molecule is usually very important to its function in the living cell. Molecular shape is crucial in biology because it determines how biological molecules recognize and respond to one another with specificity. ... Protein function is directly related to the structure of that protein.
<u>Answer:</u> The complete ionic equation contains ions
<u>Explanation:</u>
Complete ionic equation is defined as the equation in which all the substance that are strong electrolyte are present in an aqueous are represented in the form of ions.
The chemical equation for the reaction of sodium sulfide and magnesium chloride is given as:
Ionic form of the above equation follows:
The complete ionic equation for the above reaction follows:
Hence, the complete ionic equation contains ions
