Answer:
<h2>9.03 × 10²³ atoms </h2>
Explanation:
The number of atoms of Al can be found by using the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 1.5 × 6.02 × 10²³
We have the final answer as
<h3>9.03 × 10²³ atoms</h3>
Hope this helps you
Answer:
Sodium Bicarbonate on decomposition produces Carbon dioxide gas and Water vapors.
<span> 2 NaHCO</span>₂<span> </span> →<span> Na</span>₂<span>CO</span>₃<span> (s) </span>+ <span> CO</span>₂<span> (g) + H</span>₂<span>O (g)
</span>
Explanation:
Let suppose you burn 168 g ( 2 moles ) of NaHCO₃, a gas will produced and product is left behind. On measuring the product formed it will be almost equal to 105 g. This shows that the product is Na₂CO₃ and 1 mole of it is being produced after decomposition of sodium bicarbonate.
Each type of
mineral has a chemical composition that is unique such as its chemical composition
and the arrangement of atoms. For example, the mineral hematite is Fe2O3. There
are two atoms of iron (Fe) and three atoms of oxygen (O).
The answer should be <span>C. nuclear reaction.</span>
