Explanation:
They found it at Monday 5 pm so its done before that time so its 3 p.m
Answer:
Selenium has 36 valence electrons.
Answer:
c. salty.
Explanation:
From the question,
The reaction of an acid , i.e hydrochloric acid and a base i.e. , sodium hydroxide takes place , which is a type of neutralization reaction,
Where the acid and a base reacts to give salt along with water .
From the question,
The reaction is as follows -
2 HCl + NaOH → NaCl + H₂O
Hence, the resulting product is a salt ,
Therefore , the resulting solution would taste like salt.
Answer:
D) Rate = K [NO2][Cl2]
Explanation:
2 NO2 + Cl2 → 2 NO2Cl (overall reaction)
NO2 + Cl2 → NO2Cl + Cl (slow)
NO2 + Cl → NO2Cl (fast)
The rate-determining step is the slowest step in a reaction mechanism. Because it is the slowest, it determines the rate of the overall reaction.
Rate of reaction is typically given as;
Rate = K [Reactants]
In the slow step i the reaction mechanism, the reactants are; NO2 and Cl2. Since both are not intermediates, there is no need for further working out.
Rate = K [NO2][Cl2]
