Answer:
d liquid
Explanation:
Bromine occurs in the liquid state at room temperature.
Bromine is the only nonmetallic element that occurs in the liquid state at room temperature.
Answer:
- HNO3(aq)+NH3(aq)→NH4NO3(aq)+H2O(l): neutralization.
- 2Cu(s)+O2(g)→2CuO(s): redox.
- NaCl(aq)+AgNO3(aq)→NaNO3(aq)+AgCl(s): precipitation.
- 2LiOH(aq)+H2SO4(aq)→Li2SO4(aq)+2H2O(l): neutralization.
- CaCl2(aq)+K2CO3(aq)→2KCl(aq)+CaCO3(s): precipitation.
Explanation:
Hello,
Based on the given reaction and their classification as redox, neutralization or precipitation, one obtains:
- HNO3(aq)+NH3(aq)→NH4NO3(aq)+H2O(l): neutralization as ammonia which is a base, is reacting with nitric acid which is an acid to yield ammonium nitrate which is a base.
- 2Cu(s)+O2(g)→2CuO(s): redox as both copper's and oxygen's oxydation states change by increasing by 2 and reducing by 2 respectively.
- NaCl(aq)+AgNO3(aq)→NaNO3(aq)+AgCl(s): precipitation as the inital reactants are soluble but the yielded silver chloride is not.
- 2LiOH(aq)+H2SO4(aq)→Li2SO4(aq)+2H2O(l): neutralization as lithium hydroxide which is a base reacts with sulfuric acid which is an acid to yield lithium sulfate which is a salt.
- CaCl2(aq)+K2CO3(aq)→2KCl(aq)+CaCO3(s): precipitation since both calcium chloride and potassium carbonate are soluble whereas calcium carbonate is not.
Best regards.
There is a website for this, when I was in 7th grade I had a paper that looked exactly like this, just look up the answers until you find a website for it.
Answer:
D. The flesh should return to normal after you press it.
Explanation:
The water content stored in the flesh of the fish, paired with the elasticity are both indicators of freshness, and will cause the flesh to return to normal after its been pressed.
