Answer:
chemical reaction are the processes in which new substances with new properties of from are called as chemical reaction ex double displacement reaction
Explanation:
Answer:
Normalidad = 4N
%p/V = 27.6%
Explanation:
La solución 2M de carbonato de potasio contiene 2moles de carbonato por litro de solución. La normalidad son los equivalente de carbonato de potasio (2eq/mol) por litro de solución:
2moles * (2eq/mol) = 4eq / 1L = 4N
El porcentaje peso volumen es el peso de carbonato en gramos dividido en el volumen en mL por 100:
%p/V:
Masa K2CO3 -Masa molar: 138.205g/mol-
2moles * (138.205g/mol) = 276g K2CO3
Volumen:
1L * (1000mL/1L) = 1000mL
%p/V:
276g K2CO3 / 1000mL * 100
<h3>%p/V = 27.6%</h3>
The two control bases would be water and salt.
Answer:
1. H2O is a covalent bond, NaCl is an ionic bond
2. H2O uses hydrogen bonding (H-bonds), NaCl does not
3. H2O is liquid at room temperature. NaCl is solid.
