What is the difference between displacement and double displacement reactions?

steposvetlana [31]

Displacement reactions:
it is the type of reaction in which reaction starts with the help of two compounds,,, but in the product the reactant that was initially with 1st compound joins with the 2nd compound..
 A+BC⇒AC+B
example:
Fe+CuSO4⇒Cu+FeSO4
Double displacement reactions:
while it is the type of reaction in which one product is obtained parts of both reacting compounds interchange with each other..
 AB+CD⇒AD+BC
example:
AgNO3+NaCl⇒AgCl+NaNO3.....:)

A technician measures the weight of a reagent . The weight is 3269 g. What is the weight in kilograms ? Write your answer as a d

Georgia [21]

Answer:

3.269 kg

Explanation:

1000g = 1 kg. Since kg is the larger unit, you need to divide by 1000 to get kilograms. You can do the problem as a unit conversion:

3269 g × 1 kg = 3.269 kg

1000g

What is the ph of a buffer prepared by adding 0.809 mol of the weak acid ha to 0.608 mol of naa in 2.00 l of solution? The disso

Anarel [89]

The pH of the buffer is 6.1236.

Explanation:

The strength of any acid solution can be obtained by determining their pH. Even the buffer solution strength of the weak acid can be determined using pH. As the dissociation constant is given, we can determine the pKa value as the negative log of dissociation constant value.

$pKa=-log[H] = - log [ 5.66 * 10^{-7}]\\ \\pka = 7 - log (5.66)=7-0.753=6.247\\\\pka = 6.247$
