<u>Answer:</u> The given number in scientific notation is 
<u>Explanation:</u>
Scientific notation is the notation where a number is expressed in the decimal form. This means that the number is always written in the power of 10 form. The numerical digit lies between 0.1.... to 9.9.....
If the decimal is shifting to right side, the power of 10 is negative and if the decimal is shifting to left side, the power of 10 is positive.
We are given:
A number having value = 0.000000093425
Converting this into scientific notation, we get:

Hence, the given number in scientific notation is 
Protons: 29
neutrons : 35
electrons : 29
Oxidation-Reduction Reactions Suggested Reading Thus the oxidation number for oxygen in calcium oxide is -2. ... In effect, each calcium atom loses two electrons to form Ca2+ ions, and each O atom in O2 gains two electrons to form O2- ions. The net result is a transfer of electrons from calcium to oxygen, so this reaction is an oxidation-reduction reaction.
+<u>O²</u><u>(</u><u>g</u><u>)</u><u>=</u><u>2</u><u>CaO</u><u>(</u><u>s</u><u>)</u>
Explanation:
we can conclude that in the reaction there is both reduction and oxidation.
Atomic Mass Number = Atomic Number + Number of Neutrons
Answer:
Change in temperature of calorimeter is 
Explanation:
Molar mass of anethole = 148.2 g/mol
So, 0.950 g of anethole =
of anethole = 0.00641 moles of anethole
1 mol of anethole releases 5541 kJ of heat upon combustion
So, 0.00641 moles of anethole release
of heat or 35.52 kJ of heat
7.854 kJ of heat increases
temperature of calorimeter.
So, 35.52 kJ of heat increases
or
temperature of calorimeter
So, change in temperature of calorimeter is
