1. What are at least 3 effects of the oceanic plate/continental plate convergent boundary?

Chemistry
1 answer:
creativ13 [48]3 years ago
3 0

Answer 1: The correct answer is b. convergent continental-continental boundary.

A convergent continental-continental boundary refers to a convergent plate boundary where two continental plates meet or come together. When this happens, a forceful collision occurs, and structures like mountains start to form. The Himalaya mountain range is formed as a result of the convergence of the Indian and Eurasian continental plates.

Answer 2: The correct answer is d. convergent oceanic-oceanic boundary.

Volcanic island arcs refers to a curved line of volcanoes formed from the subduction (sinking) of one oceanic plate below another plate. Examples of volcanic island arcs include Japanese Islands and Alaskan Islands.

Answer 3: The correct answer is b.convergent oceanic-continental boundary.

A continental volcanic arc is an arc-shaped chain of volcanoes that form from the subduction of an oceanic plate under a continental plate.

(5 pts) Calculating Heat from Thermochemical Equations
Vadim26 [7]

The heat that is released by the combustion of 3.5 moles of methane is 3115 kJ/mol.

<h3>What is a thermochemical equation?</h3>

A thermochemical equation is a reaction equation that incorporates the amount of heat lost/gained.

In this case, the reaction equation is; CH4 + O2 ----->CO2 + 2H2O dH = -890 kJ/mol

If 1 mole of methane releases 890 kJ/mol

3.5 moles of methane will release 3.5 moles * 890 kJ/mol/1 mole

= 3115 kJ/mol

Classify these salts as acidic, basic, or neutral. KCL, NH4Br, K2CO3, NaCN, LiClO4? This is what I put but got it wrong: KCl = b
MaRussiya [10]
In classifying salts as neutral, acidic, or basic, it is important to take note of the strength of the acids and bases that they come from. A strong acid and strong base produce a neutral salt. A weak acid and strong base produce a basic salt. A strong acid and weak base produce an acidic salt. So the answers must be:

KCl = neutral (from HCl and KOH)
NH4Br = acidic (from NH4 and HBr)
K2CO3 = basic (from KOH and H2CO3)
NaCN = basic (from NaOH and HCN)
LiClO = basic (from LiOH and HClO)

Consider the following reaction at 298K.
lakkis [162]

The true statements are;

  • K < 0
  • Eocel  < 0

<h3>What is a redox reaction?</h3>

We define a redox reaction as one in which a specie is oxidized and another is reduced.

Now;

Eo cell = cell potential = -0.13 V - (+0.34 V) = -0.47 V

n =number of moles of electrons = 2 mole of electrons

K = equilibrium constant

ΔG = change in free energy

Eo cell = 0.0592/n log K

-0.47 =  0.0592/2 log K

log K =  -0.47  * 2/0.0592

K = 1.3 * 10^-16

ΔG = -nFEo cell

ΔG = -(2 * 96500 * -0.47)

ΔG = 90.7kJ

Which of the statements below correctly describes the chair conformations of trans-1,4-dimethylcyclohexane? A. The higher energy
Taya2010 [7]

Answer:

D. The higher energy chair conformation contains two axial methyl groups.

Explanation:

The diaxial trans-1,4-dimethylcyclohexane has the highest energy (the least stable) and the diequatorial chair conformation has the lowest energy (the most stable).

The diaxial conformation has a higher energy due to the interaction between the methyl groups.
