A neutralization process is a reaction between an acid and a base which yields a salt and water. From the choices, a neutralization reaction would be: 2 HBr + Ca(OH)2 yields CaBr2 + 2 H2O. Moreover, <span>NH3 + HCl yields NH4Cl is also a neutralization reaction. The complete reaction is actually NH4OH + HCl --> NH4Cl + H2O. NH4OH is the aqueous solution of NH3. This reaction is still a neutralization reaction.
On the other hand, the reaction </span><span>HCl + HBr yields H2 + ClBr is not valid. There is no reaction between HCl and HBr because both are strong acids. They would just dissociate into ions like H+, Cl- and Br-.
The valid reaction that is clearly not a neutralization process is </span><span>H2 + Br2 yields 2 HBr. This is a combination reaction yielding a strong acid HBr.</span>
Answer:
10kg = 10 x 1000 = 10,000g
Explanation:
To know the quantity with the largest mass, we have to express all the units in grams:
for: 2 x 10mg = 2 x 10 x 10⁻³ = 0.02g
0.001kg = 0.001 x 1000 = 1g
1 x 10⁵ng = 1 x 10⁵ x 10⁻⁹ = 0.0001g
2 x 10²cg = 2 x 10² x 10⁻² = 2g
10kg = 10 x 1000 = 10,000g
Note:
10⁻ ¹ deci(d)
10⁻² centi(c)
10⁻³ milli(m)
10⁻⁹ nano(n)
10³ kilo(k)

Answer:
D. The number of atoms present
Explanation:
In a balanced equation, coefficients always represent the number of atoms present.
The appropriate response is high. The best approach to consider it is those molecules have more vitality than the normal and it is unequivocally those higher enthusiastic ones that have enough vitality to break the intra-molecular forces and leave. By the way this is the reason when we sweat we chill off - the most enthusiastic molecules vanish diverting warmth.
