Temperature is the independent variable in this experiment
Explanation:
A respirometer is a tool used to calculate the rate of breathing of a living organism by calculating the amount of exchange of oxygen and/or carbon dioxide.
When the yeast cells are given sugar in an aerobic (oxygen-containing) environment, then the yeast.
There would be an air bubble at the tip of the respirometer, and our dependent variable is the difference in the duration of the bubble, i.e. incubate in a warm water bath at body temperature (37 ° C) for about 20 minutes.
Answer is: directly up.
Neon (Ne) is noble gas with atomic number 10 and atomic mass around 20.
1) directly up is noble gas helium (He) with atomic mass around 4.
2) directly down is noble gas argon (Ar) with atomic mass around 40.
3) directly to the left is florine (F), with smaller atomic mass, but also from different group.
4) directly to the right there no elements, because noble gases are far right in 18. group of Periodic table.
If the atom is neutral (meaning, not charged) the number of electron is equal to the number of protons. The mass number of an atom is the sum of the number of proton and the number of neutrons. From the given above, the mass number of gallium is 31 + 39. The answer is letter D. 70.
Answer:
a) find attached image 1
b) find attached image 2
Explanation :
The more stable radical is formed by a reaction with smaller bond dissociation energy.
since the bond dissociation for cleavage of the bond to form primary free radical is higher, more energy must be added to form it. This makes primary free radical higher in energy and therefore less stable than secondary free radical.
<span>1. </span>Heat
gained in a system can be calculated by multiplying the given mass to the
specific heat capacity of the substance and the temperature difference. It is
expressed as follows:<span>
Heat = mC(T2-T1)
Heat = 100(4.184)(20 - 16)
<span>Heat = 1673.6 J</span></span>
