What is the molarity of NaOH if 83.5 mL of NaOH is needed to react with 35.0mL of a 0.275 M solution of H2SO4?

Lostsunrise [7]

Answer:

0.231 mol/L

Explanation:

The first step is to write the balanced equation for this reaction:

$H_{2}SO_{4} +2NaOH ===> Na_{2}SO_{4} +2H_{2}O$

The second step is to find the number of moles in the acid:

number of moles = volume * concentration

= 0.035 L * 0.275 mol/L

= 0.009625 mol

The third step is to use the molar ratio from the balanced chemical equation to find the number of moles of NaOH that can neutralize 0.009625 mol of sulphuric acid.

n(sulphuric acid) : n(sodium hydroxide)

1 : 2

0.009625 mol : x

x = 0.01925 mol

Fourth step is to calculate the concentration of sodium hydroxide:

$concentration = \frac{number of moles}{volume} = \frac{0.01925}{0.0835} =0.231 mol/L$

Explain three ways in which the sugar revolution impacted on the caribbean

denis-greek [22]

Answer:

During the colonial period, the arrival of sugar culture deeply impacted the society and economy in the Caribbean. It not only dramatically increased the ratio of slaves to free men, but it increased the average size of slave plantations

The negative impact of the slave trade on the development of the Caribbean islands. The slave trade had long lasting negative effects on the islands of the Caribbean. The native peoples, the Arawaks, were wiped out by European diseases and became replaced with West Africans

The sugar revolutions were both cause and consequence of the demographic revolution. Sugar production required a greater labor supply than was available through the importation of European servants and irregularly supplied African slaves

At 20 °C, a saturated aqueous solution of silver acetate, AgCH3CO2, contains 1.0 g of silver compound dissolved in 100.0 mL of s

tester [92]

Answer:

Ksp = 0.0036.

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to calculate the Ksp of the silver acetate, by knowing that its equilibrium expression is:

$Ksp=[Ag^+][CH_3COO^-]$

Next, we calculate molar concentration of the ions in the solution, the same to that of the acetate ions, due to the 1:1 mole ratio, as follows:

$[Ag^+]=[CH_3COO^-]=\frac{1.0g/(166.9122 g/mol)}{0.1000L} =0.0600M$

Therefore, the Ksp is:

$Ksp=0.0036$

Regards!
