A .gamma
Because composed of photons, which have neither mass nor electric charge and, as a result, penetrates much further through matter than either alpha or beta radiation.
Answer:
Synthesis
Explanation:
The reaction:
2Mg + O₂ → 2MgO
This reaction above is a synthesis or combination reaction. In such reaction, several products combines to give a single product.
The formation of a single product from two or more reactants is classified under this type of reaction
The driving force for this reaction type is the large and negative heat of formation of the product.
Answer:
D)2.0
Explanation:
Avogadro’s number represent the number of the constituent particles which are present in one mole of the substance. It is named after scientist Amedeo Avogadro and is denoted by
.
Also, it is the number of particles in exactly 12.000 g of isotope carbon 12.
Avogadro constant:-

Thus,
Number of particles as 12 grams of carbon-12 constitutes 1 mole
<u>Twice the number of particles as 12 grams of carbon-12 constitutes 1*2 mole</u>
Thus, moles in the substance = 2.0 moles
