Answer:
Freezing and condensation
Explanation:
Because they are exothermic, they release energy
673.5 in scientific notation would be 6.735 X 10^2.
The answer to this question would be: false
Solid foods have a smaller surface that can be digested by enzyme compared to the liquids food. Liquid food like milk can easily be digested as the substrate spread in the solution to the enzyme can bind freely to the substrate. In solid food, the area that can be digested would be only the outer part of the food. That is why organism have teeth so the food can be cut into smaller pieces, increasing the surface area that can be digested.
<span>The mass of the nail would increase, because the iron is adding oxygen to its chemical composition. This would increase the overall mass. If the mass increases from 23.2g to 24.1g, then the increase would be the difference between the two masses, or 0.9g.</span>
<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
