Answer:
Chemical change.
Explanation:
When it is heated it decomposes into mercury and oxygen gas. The mercury oxide reactant becomes the silver color of mercury. Hence, a color change can be noticed throughout the reaction.
Answer:
CO₃²⁻(aq) + 2H⁺(aq) → CO₂ (g) + H₂O (l)
Explanation:
The balanced reaction between Na2CO3 and HCl is given as;
Na₂CO₃ (aq) + 2 HCl (aq) → 2 NaCl (aq) + CO₂ (g) + H₂O (l)
The next step is o express the species as ions.
The complete ionic equation for the above reaction would be;
2Na⁺(aq) + CO₃²⁻(aq) + 2H⁺(aq) + 2Cl⁻(aq) → Na⁺(aq) + Cl⁻(aq) + CO₂ (g) + H₂O (l)
The next step is to cancel out the spectator ion ions; that is the ions that appear in both the reactant and product side unchanged.
The spectator ions are; Na⁺ and Cl⁻
The net ionic equation is given as;
CO₃²⁻(aq) + 2H⁺(aq) → CO₂ (g) + H₂O (l)
M=260 g
M=414.215 g/mol
n=m/M
n=260 g / 414.215 g/mol = 0.6277 mol
Answer:
no it is a ionic compound
Answer:
"Synchronize" means to place together in terms of time and manner.
Explanation:
- In the word 'synchronize' the prefix added is 'syn'.
- The prefix 'syn' has been derived from the Greek language.
- The prefixes 'syn' and 'sym' are equivalent in terms of their meanings.
- The meaning of the prefix is to put 'together'.
- The words formed by adding the prefix es 'syn' and 'sym' highlights the meaning of togetherness of the specific things.
- Here, the word 'synchronize' means to put together in terms of time and manner.
