Hello!
First, HNO₃ dissociates in the following way:
HNO₃(aq) → H⁺(aq) + NO₃⁻(aq)
Next, there is a neutralization reaction with Methylamine:
H⁺(aq) + CH₃NH₂(aq) → CH₃NH₃⁺(aq)
Finally, the formed methylammonium ion weakly dissociates in the following way:
CH₃NH₃⁺(aq) + H₂O(l) ⇄ H₃O⁺(aq) + CH₃NH₂ (aq)
From this sequence of reactions, we can see that the resulting solution would be slightly more acidic than the initial one, as the buffer solution resists the addition of strong acid.
Have a nice day!
The answer is Solid.
This is on account of the substances that develop a solid are packed in a settled, firmly pressed geometric plan.
to write 0,0045 in scientific notation, we will have to move the decimal point three point to right, which literally means multiplying by 1000=103 . Hence in scientific notation 0.0045=4.5×10−3 (note that as we have moved decimal three point to right we are multiplying by 10−3 this is an example
Answer:
In a salt halogen element have negative charge if it gain an electron.
Explanation:
Fluorine,chlorine, bromine and iodine belongs to the family of halogen elements.These elements have high tendency to acquire electron due their high electronegativity.
When a halogen element forms a salt for example potassium chloride(KCl), the Cl or chlorine is a halogen element which get negative charge when it gains or acquires an electron.
Cl2 + NaI -> NaCl + I2
We are unbalanced with Chlorine and Iodine so we can do this:
Cl2 + 2NaI -> 2NaCl + I2
Reactants: Cl = 2, Na = 2, I = 2
Products: Cl = 2, Na = 2, I = 2
So we are balanced.
