Answer:

10.1 g = 0.0011 kg is incorrect

Explanation:

When converting from g to kg we divide by 1000 and when converting from kg to g we multiply by 1000.

765 g = 0.765 kg is correct since 1 kg = 1000 g  

10.1 g = 0.0011 kg is incorrect since 1 kg = 1000 g

10.1 g = 0.0101 kg is correct

1000 g = 1 kg is the correct conversion factor

5.44 g = 0.00544 kg is correct since 1 kg = 1000 g

Natali [406]

Answer:

D 2,2

Explanation:

We can see that there are 2 chlorines on the reactant side so there has to be a 2 on the product side

Now we have Na + Cl2 --> 2NaCl

The problem now is that there are 2 sodiums on the product side so add a 2 to the Na on the reactant side

2Na + Cl2 --> 2NaCl

Now it's balanced!

A buffer solution is composed of 7.50 mol of acid and 4.75 mol of the conjugate base. If the pKa of the acid is 4.90 , what is t
Mamont248 [21]

Answer:

The correct answer is: pH= 4.70

Explanation:

We use the <em>Henderson-Hasselbach equation</em> in order to calculate the pH of a buffer solution:

pH= pKa + log   \frac{ [conjugate base]}{[acid]}

Given:

pKa= 4.90

[conjugate base]= 4.75 mol

[acid]= 7.50 mol

We calculate pH as follows:

pH = 4.90 + log (4.75 mol/7.50 mol) = 4.90 + (-0.20) = 4.70
