The answer is milk spoils because spoiling doesn't have to to with the chemical foundation.
What they have in common is that they both have the same number of atoms. Hope this helps. :)
Answer:
a solution color becoming less intense due to dilution- is not an evidence of a chemical reaction
bubbles (gas formation) - evidence of a chemical reaction
explosion or fire - evidence of a chemical reaction
changes in color- evidence of a chemical reaction
precipitation- evidence of a chemical reaction
changes in temperature - evidence of a chemical reaction
a solid liquifying - is not an evidence of a chemical reaction
solution colors mixing - is not an evidence of a chemical reaction
Explanation:
A chemical change is not easily reversible and yields new substances. It is often accompanied by a loss or gain of heat.
In the answer section, i have shown some evidences that lead us to conclude that a chemical reaction has taken place. The occurrence of a chemical change often goes with the formation of new substances as earlier stated and any of these signs may accompany the process.
For instance, when a metal is dropped in dilute acid solution, bubble of hydrogen gas indicates that a chemical reaction has taken place.
Answer:
Heat by radiation will most likely be transferred through empty space by thermal radiation.
Explanation:
Radiation is method in which heat is transferred without depending upon the contact of heat source and the heated object, which happens in the case of conduction and convection. The heat can be transferred through the empty space by the help of thermal radiation. This complete phenomenon is called as the infrared radiation. Which is a type of electromagnetic radiation. The heat is found to be convected in the atmosphere when the warm particles are transferred from one location to another.
Answer: Thus pOH has value of 8.19
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pOH is calculated by taking negative logarithm of hydroxide ion concentration.
Putting in the values:
Thus pOH has value of 8.19
