Answer:

d. the conjugate base.

Explanation:

The general reaction of a weak acid, HA, with a strong base YOH, is:

HA + YOH → A⁻ + H₂O + Y⁻

<em>Where A⁻ is the conjugate base of the weak acid and Y⁻ usually is a strong electrolyte.</em>

<em />

That means after he complete reaction you don't have weak acid nor strong base, just conjugate base that will be in equilibrium with water, thus (Strong electrolyte doesn't change pH:

A⁻ + H₂O ⇄ HA + OH⁻

As the equilibrium is producing OH⁻, the pH of the solution is being affected for the conjugate base

Right option:

<h3>d. the conjugate base. </h3>

At what temperature, in Celsius, will 88.0 g of Ne exert a pressure of 350. kPa in a
bezimeni [28]

Answer:

191 °C

Explanation:

We'll begin by calculating the number of mole in 88.0 g of Ne. This can be obtained as follow;

Mass of Ne = 88.0 g

Molar mass of Ne = 20 g/mol

Mole of Ne =?

Mole = mass /molar mass

Mole of Ne = 88 / 20

Mole of Ne = 4.4 moles

Next, we shall determine the temperature. This can be obtained as follow:

Mole of Ne = 4.4 moles

Pressure (P) = 350 KPa

Volume (V) = 48.5 L

Gas constant (R) = 8.314 KPa.L/Kmol

Temperature (T) =?

PV = nRT

350 × 48.5 = 4.4 × 8.314 × T

16975 = 36.5816 × T

Divide both side by 36.5816

T = 16975 / 36.5816

T = 464 K

Finally, we shall convert 464 K to celsius temperature. This can be obtained as follow:

T(°C) = T(K) – 273

T(K) = 464 K

T(°C) = 464 – 273

T(°C) = 191 °C

Thus, the temperature is 191 °C

How many fe(ii) ions are there in 10.0 g of feso4?
hram777 [196]

Iron sulfate can be shown as FeSO4 and the number mole of FeSO_4  can be determined as

Molar mass of Iron sulfate = 151 g /mole

Mass of Iron sulfate = 10 g

Mole = mass /molar mass\\ = 10 /151 = 0.066 mol

Number of Fe ion  can be determined as

Mole = Number of ion / Avogadro number\\ 0.066 = Number of ion / 6.02 * 10^23\\ Number of ion = 3.98 * 10^22

Thus, 3.98 * 10^22 ions are present in Iron sulfate
