Answer:

D. Zn → Zn²⁺ + 2e⁻, 2H⁺ + 2e⁻ → H₂.

Explanation:

  • It is a redox reaction that is consisted of two half-reactions:

Oxidation reaction:

Zn losses 2 electrons and is oxidized to Zn²⁺:

<em>Zn → Zn²⁺ + 2e⁻.</em>

<em></em>

Reduction reaction:

H⁺ gains 1 electron and is reduced to H:

<em>2H⁺ + 2e⁻ → H₂.</em>

<em></em>

<em>So, the right choice is: D. Zn → Zn²⁺ + 2e⁻, 2H⁺ + 2e⁻ → H₂.</em>

Solar- the sun is not always shining, for example at night you can't get any energy from the sun

Select the correct answer. Elements Electronegativity aluminum (Al) 1.61 calcium (Ca) 1 carbon (C) 2.55 chlorine (Cl) 3.16 fluor
marishachu [46]

Answer: Fe - O


Explanation:


1) Start by showing the chart information in a more understandable way:


Elements ---------- Electronegativity


aluminum (Al) ----- 1.61


calcium (Ca) ------- 1


carbon (C) ---------- 2.55


chlorine (Cl) -------- 3.16


fluorine (F) --------- 4


hydrogen (H) ------ 2.2


iron (Fe) ------------- 1.83


nitrogen (N) --------- 3.04


oxygen (O) ----------- 3.44


phosphorus (P) ----- 2.19


potassium (K) -------- 0.82


silicon (Si) ------------- 1.9


sulfur (S) --------------- 2.58


2) Find the electronegativity differences for the atoms in each compound:


i) Ca – Cl: 3.16 - 1 = 2.16


ii) Fe – O: 3.44 - 1.83 = 1.61


iii) H – S: 2.58 - 2.2 = 0.38


iii= F – F = 4 - 4 = 0


3) Analysis


i) The higher the electronegativity difference between two non-metal elements, the the more the polar the covalent bond. Therefore, the bond H - S is the most polar among the non-metal - non-metal bonds listed. But 0.38 is a small difference, so this is not very polar.


ii) For metal - non-metal bonds, when the difference in electronegativities is too high (close to or greater than 2.0) the ionic character is dominant, and so you cannot classify the bond as polar but as ionic. Therefore, Ca - Cl with 2.16 electronegativity difference is a ionic bond.


iii) The bond in Fe – O has electronegativty difference of 1.61, so it is yet covalent, and highly polar.

In which are the ionic solids ranked in order of increasing melting point?
abruzzese [7]

Answer:A

Explanation:

The melting points of solids depend in the relative sizes of ions in the ionic lattice. The smaller the relative sizes of the ions, the higher the lattice energy and the stronger the lattice hence higher melting point. Comparing relative ionic sizes, fluoride ion is lesser in size than chloride ion hence NaF has a higher melting point than NaCl.

At what Celsius temperature does 0.750 mol of an ideal gas occupy a volume of 35.9 L at 114 kPa?
shepuryov [24]

382.85  Celsius is the temperature does 0.750 moles of an ideal gas occupy a volume of 35.9 L at 114 kPa.

Explanation:

Given data:

number of moles of the gas  = 0.75 moles

volume of the gas = 35.9 liters

pressure of the gas = 114 KPa or 1.125 atm

R = 0.0821 latm/moleK

temperature of the gas T = ?

The equation used to calculate temperature from above data is ideal gas law equation.

the equation is :

PV = nRT

T = \frac{PV}{nR}

Putting the values in the above rewritten equation:

T = \frac{1.125 X 35.9}{0.75 X 0.0821}

T = 655.9 K

To convert kelvin into celsius, formula used is

K = 273.15+ C

putting the values in the equation

C = 656 - 273.15

   = 382.85  Celsius
