Hydrochloric acid<span> is known as a monoprotic </span>acid<span> because it loses one hydrogen ion when it is dissolved in water. It is one of seven strong </span>acids<span>. The base sodium hydroxide is more commonly known as lye. It is used in the manufacture of products such as soap, paper and detergent.</span>
The answer is A)
A nuclear reaction releases more energy per gram and appears to violate the law of conservation of mass.
The mass number is the sum of the protons and neutrons
64 = #protons + #neutrons
Find the number of protons given the number of neutrons
64 = #protons + 33
#protons = 31
In a neutral element (such as this), the number of electrons equals the number of protons
#electrons = #protons
#electrons = 31
Average speed (aka average velocity) is the change in displacement (distance) over the chance in time.
The average velocity of the baseball is 15 meters/sec
The answer for #1 description is Hypothesis: Redi's hypothesis is that flies can only be produced by other flies.
The answer for #2 description is Control: The control group was the meat in the container with no covering, thus leaving it open to the flies.
The answer for #3 description is Independent Variable: The independent variable is covering the meat in the container with a mesh so the flies can't get to it.
The answer for #4 description is Dependent Variable: The dependent variable is the presence of maggots on the meat that is observed in response to the independent variable.
The answer for #5 description is Constants: The constants or factors that are kept the same for both groups are the location of containers and temperature, so that it was not one of these that caused the change.
