β⁻ emission is an
emission of an electron from the parent atom while converting a neutron into a
proton.<span> Hence, the formed daughter nucleus has the same
number of mass but the atomic number is higher by 1 and number of neutrons is
lower by one than the parent atom.</span><span>
After a β⁻<span> emission of ¹⁰⁶Ru, the formed daughter nucleus
should have 106 as mass number but (44 + 1) = 45 </span>as the atomic number. </span><span>
<span>Hence the daughter nucleus is </span>Rh<span> (</span>Rhodium<span>) which has </span>45<span> protons
(atomic number).</span></span>
Chlorophyll: green
Anthocyanins: red
Carotene: orange.
Sorry I couldn’t find the 4th one
Answer:
The correct answer would be - observing with the help of five senses.
Explanation:
To find and describe the physical properties of the given substance or the solution or liquid students can observe using their five senses. By looking at the liquid one can find its state and color, by smelling students can find the odor of the sample, by touching it one can observe and describe the texture.
Fluidity can also be measure by the touch if the solution is viscous or free-floating. By using a thermometer and using a graduated cylinder one can find the temperature at room temperature and the weight of substance respectively.
Answer:
A mixture is a physical combination of substances thus it only requires physical processes to separate. However, a compound is chemically combined and can only be separated by chemical processes. Therefore, it is much harder to separate a compound than a mixture.
Answer:
Electric engines have efficiencies of roughly 90% whilst combustion engines about 10% to 30%. This is because combustion engines emit much more heat, which is always energy that is not used as work, and thus increases inefficiency.
