Answer:

AgNO3 is soluble dissolves in water to give the Ag+ ion and the NO3- ion

Pb(C2H3O2)2 is soluble in water to give the Pb2+ ion and the CH3COO- ion

KNO3 is soluble in water to give K+ ion and the NO3- ion

(NH4)2S is soluble in water to give the NH4+ ion and the S2- ion

Explanation:

This question requires a knowledge of a few solubility rules

All nitrates are soluble in water

All group I salts are soluble in water

All ammonium salts are soluble in water

All ethanoates are soluble in water except silver ethanoate

Answer:

According to the solubility rules:

<u>1. Silver nitrate</u>: AgNO₃ is soluble.

Reason: Nitrates (NO₃⁻) are soluble.

AgNO₃ (aq) → Ag⁺(aq) + NO₃⁻(aq)

<u>Ions present</u>: silver ion (Ag⁺) and nitrate ion (NO₃⁻)

<u>2. Lead(II) acetate:</u> Pb(C₂H₃O₂)₂ is soluble.

Reason: Acetates (C₂H₃O₂⁻) are soluble

Pb(C₂H₃O₂)₂ → Pb²⁺(aq) + 2 CH₃COO⁻(aq)

<u>Ions present</u>: lead(II) ion (Pb²⁺) and two acetate ions (CH₃COO⁻)

<u>3. Potassium nitrate</u>: KNO₃ is soluble.

Reason: Nitrates (NO₃⁻) are soluble and group-1 ions such as K⁺ are soluble.

KNO₃ (aq) → K⁺(aq) + NO₃⁻(aq)

<u>Ions present:</u> potassium ion (K⁺) and nitrate ion (NO₃⁻)

<u>4. Ammonium sulfide: </u>(NH₄)₂S is soluble.

Reason: Ammonium (NH₄⁺) ions are soluble

(NH₄)₂S (aq) → 2 NH₄⁺(aq) + S²⁻(aq)

<u>Ions present:</u> two ammonium ions (NH₄⁺) and sulphide ion (S²⁻)

If the theoretical yield of a reaction is 22.7 g and the actual yield is 21.0 g , what is the percent yield?
guajiro [1.7K]
Percentage yield = actual yield/theoretical yield

So divide 21.0 g by 22.7 g and multiply it by 100 to find the percentage yield

14. An enzyme-catalyzed reaction was carried out with the substrate concentration initially a thousand times greater than the Km
emmainna [20.7K]

Answer:

27 min

Explanation:

The kinetics of an enzyme-catalyzed reaction can be determined by the equation of Michaelis-Menten:

v = \frac{vmax[S]}{Km + [S]}

Where v is the velocity in the equilibrium, vmax is the maximum velocity of the reaction (which is directed proportionally of the amount of the enzyme), Km is the equilibrium constant and [S] is the concentration of the substrate.

So, initially, the velocity of the formation of the substrate is 12μmol/9min = 1.33 μmol/min

If Km is a thousand times smaller then [S], then

v = vmax[S]/[S]

v = vmax

vmax = 1.33 μmol/min

For the new experiment, with one-third of the enzyme, the maximum velocity must be one third too, so:

vmax = 1.33/3 = 0.443 μmol/min

Km will still be much smaller then [S], so

v = vmax

v = 0.443 μmol/min

For 12 μmol formed:

0.443 = 12/t

t = 12/0.443

t = 27 min

How many moles of LiOH are needed to react completely with 25.5 g of CO2
LekaFEV [45]

Answer:

3.18 mol

Explanation:

2LiOH+CO_{2}-> Li_{2}CO_{3} +H_{2}O

n(CO2) = mass/ Mr.

             = 25.5 / 16

             = 1.59 mol

As per the equation above,

n(LiOH) : n(CO2)

     2      :    1

∴  3.18   :  1.59

Sound wave a has lower frequency than sounds wave b but both waves have the same amplitude . What must also be true of these two
Nady [450]

Explanation:

Higher the frequency smaller will be the wavelength. Higher frequency have shorter wavelength and lower frequency waves have larger wavelength. Also, Beats are formed by the superposition of two waves with slightly different frequencies but with similar amplitudes. In time, waves switch between constructive interference and disruptive interference, giving the resultant wave a time-varying amplitude.
