LekaFEV [45]

Answer:

1) Condensation.

2) See below.

Explanation:

1) The warmer water vapour from the surroundings came into contact with the cooler inner surface of the glass jar and condensed, forming the water droplets (water vapour) on the inside of the glass jar.

2) As condensation occurs, condensed water vapour will drip into the water solution in the glass jar, causing the water to rise in the glass jar.

Write the net ionic equation (including phases) that corresponds to fe(clo4)2(aq)+na2co3(aq)
olganol [36]
<h2>The net ionic equation that correspond to Fe(ClO4)2 +Na2CO3  is</h2>

<u>Fe ^2+(aq)  +CO3^2-(aq) →  FeCO3 (s)</u>


<h3>Explanation</h3><h3 /><h3>write the  balance chemical equation</h3>

  Fe(ClO4)2 (aq) + Na2CO3(aq)→ FeCO3 (s)  + 2 NaClO4

<h3>write the ionic equation</h3>

 Fe^2+(aq)  + 2ClO4 ^-(aq)  + 2Na^+(aq) +CO3^2- (aq) → FeCO3 (s)   + 2Na^+ + 2ClO4^-

<h3>cancel the  spectator ions   in both side</h3>
  • that is ( 2ClO4^-  and 2Na+)

the ionic equation  is therefore

<u>Fe^2+(aq)   + CO3^2-  →FeCo3(s)</u>

How many liters of hydrogen gas are formed from the complete reaction of 1.03 mol of C? Assume that the hydrogen gas is collecte
aliina [53]

Answer:

27 liters of hydrogen gas will be formed

Explanation:

Step 1: Data given

Number of moles C = 1.03 moles

Pressure H2 = 1.0 atm

Temperature = 319 K

Step 2: The balanced equation

C +H20 → CO + H2

Step 3: Calculate moles H2

For 1 mol C we need 1 mol H2O to produce 1 mol CO an 1 mol H2

For 1.03 moles C we'll have 1.03 moles H2

Step 4: Calculate volume H2

p*V = n*R*T

⇒with p = the pressure of the H2 gas = 1.0 atm

⇒with V = the volume of H2 gas = TO BE DETERMINED

⇒with n = the number of moles H2 gas = 1.03 moles

⇒with R = the gas constant = 0.08206 L*Atm/mol*K

⇒with T = the temperature = 319 K

V = (n*R*T)/p

V = (1.03 * 0.08206 *319) / 1

V = 27 L

27 liters of hydrogen gas will be formed

What is the standard reduction potential, E, for the half-reaction Al3+ (aq)
olchik [2.2K]

Answer:

E° = -1.66 V

Explanation:

The standard reduction potential is also known as the standard electrode potentials and it tries to find the probability that an element will be reduced or undergo reduction.

From activation series online showing the standard reduction potentials for half cells, the standard reduction potential of Al3+ (aq) + 3e- -> Al(s) is;

E° = -1.66 V
