Answer:
6.02x10^23 atoms
Explanation:
From the background knowledge of Avogadro's hypothesis, we understood that 1mole of any substance contains 6.02x10^23 atoms. This implies that 1mole of carbon also contains 6.02x10^23 atoms.
1mole of carbon = 12g.
Therefore, 12g of carbon contains 6.02x10^23 atoms
just K Y M kid. to be honest none of this is worth it
Answer:
mezcla homogénea
El agua en sí es un ejemplo de mezcla homogénea. Todo el agua, excepto la más pura, contiene minerales y gases disueltos. Estos se disuelven en todo el agua, por lo que la mezcla se presenta en la misma fase y es homogénea.
I think the effect of increasing temperature would be; the equilbrium will shift back wards. Increase in temperature favors backward reaction since the forward reaction is exothermic and the backward reaction is endothermic. Therefore, the equilibrium will shift back wards, and there will be more reactants (H2 and Cl2) compared to the products
441 g CaCO₃ would have to be decomposed to produce 247 g of CaO
<h3>Further explanation</h3>
Reaction
Decomposition of CaCO₃
CaCO₃ ⇒ CaO + CO₂
mass CaO = 247 g
mol of CaO(MW=56 g/mol) :

From equation, mol ratio CaCO₃ : CaO = 1 : 1, so mol CaO :

mass CaCO₃(MW=100 g/mol) :
