<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2>

<h2>_____________________________________</h2><h2>CALORIMETER:</h2>
Calorimeter is device used for the measurement of heat. In a calorimeter we can use the temperature change of water to quantify an amount of heat. A calorimeter just captures all the energy released (or absorbed) by a reaction in the water. So Option A and B are wrong as calorimeter don't have anything to do with providing the heat or letting the the heat in, as it is the insulated calorimeter too.
<h2>_____________________________________</h2><h2>Energy in the reaction:</h2>
In the formation of any bond there is equal amount of heat required as to break that bond. It means Energy released in the making of bond is equal to the energy required in the breaking of the bond. So Option D is wrong as it says we need more energy in making then breaking.
<h2>_____________________________________</h2><h2>Enthalpy:</h2>
Enthalpy is the total heat content of the system. As we provide energy to the reactants and the product is formed, so The enthalpy(heat content) of product is more than the Enthalpy of the reactant, Thus Option C is correct.
Enthalpy is denoted by H or Q, its formula is,
H = U + PV
Where,
U is internal energy
PV is equals to Work done ; P = Pressure, V = Volume

Answer:
True
Explanation:because of the motion
Magnesium (Mg) has atomic number 12 with electronic configuration :

The valence shell of Mg is 3s which has 2 electrons as shown in above electronic configuration.
Therefore, A = 3 and B =2
Answer:
Organelles, prokaryotic, organelles, cytoplasm, prokaryotic, nucleus
Explanation:
<u>Organelles</u> are membrane bound only in eukaryotic ccells.
Prokaryotic cells unlike eukaryotic cells, do <u>not have membrane bound organlles.</u>
Something that is found in <u>both prokaryotic and eukaryotic cells is the cytoplasm</u>, which is fluid that is inside the whole cell.
Unlike eukaryotic cells, <u>prokaryotic cells have loose DNA</u>, which floats around the cell quite literally.
The only way DNA is stored in eukaroyotic cells is in the <u>nucelus</u>, which is only found in eukaryotic cells, not prokaryotic.
Hope this helps ;)
