The equilibrium pressure of H2 is 0.96 atm and the impossible solution of the quadratic equation is -1.379.
Equilibrium pressure of H2
The equilibrium pressure of H2 is calculated by creating ICE table as follows;
2 N H3 ( g ) ⟷ N2( g ) + 3H2
I: 1 1 1
C: -2x x 3x
E: 1 - 2x 1 + x 1 + 3x
0.83(1 - 2x)² = (1 + x)(1 + 3x)³
0.83(1 - 4x + 4x²) = (1 + x)((1 + 3x)³)
0.83 - 3.32x + 3.32x² = (1 + x)((1 + 3x)³)
0.83 - 3.32x + 3.32x² = 1 + 10x + 36x² + 54x³ + 27x⁴
27x⁴ + 54x³ + 32.68x² + 13.32x + 0.17 = 0
x = -1.379 or - 0.013
Partial pressure of H2 = 1 + 3x
H2 = 1 + 3(-1.379)
H2 = -3.13 atm
H2 = 1 + 3(-0.013)
H2 = 0.96 atm
Thus, the equilibrium pressure of H2 is 0.96 atm and the impossible solution of the quadratic equation is -1.379.

Answers
Answer: b} The exact time when an individual atom will decay can be accurately predicted.
c} After each half-life, the amount of radioactive material is reduced by half.
Explanation:
All radioactive decay follows first order kinetics.
Rate law expression for first order kinetics is given by:
where,
k = rate constant
t = time taken for decay process
a = initial amount of the reactant
a - x = amount left after decay process
Expression for calculating half life, which is the time taken by the half of the reactants to decompose is:
Answer:
For plato, the answer is C: after each half tile, the amount of radioactive material is reduced by half

Answer:
I assume you mean which best describes heat.
The answer is The energy transferred between samples of matter because of a difference in their temperatures.
To explain this further, heat is total energy of an object, temperature is average energy. The change in temperature between two objects is called heat!
Think about transfers of heat in everyday terms: if you put an ice cube in your tea (I don't know, just bear with me), the cold does not transfer to the tea. The heat of the tea is transferred to the ice cube! And this is clearly a difference in heat.

Answer:
The statements that describe Mg are:
1. is very reactive as a metal
2. forms a basic solution in water
3. is found in nature only combined with other elements
Explanation:
Magnesium is a s-block chemical element that belongs to group 2 and period 3 of the periodic table. It is a reactive alkaline earth metal that exists in nature only in the combined state with elements such as carbon, calcium and oxygen.
Magnesium reacts with water at room temperature, to give strongly basic metal oxide of the formula, MgO, which forms a basic solution in water.
It also reacts vigorously with halogens such as chlorine and bromine, to form salts.
Final answer:
Magnesium is a highly reactive alkaline earth metal that forms a basic solution in water and can react vigorously with alkali metals to form salts. It consists of diatomic molecules in its elemental form.
Explanation:
Magnesium is one of the alkaline earth metals, which are found in Group 2 of the periodic table. It is a highly reactive metal that forms a basic solution in water and can react vigorously with alkali metals to form salts. Magnesium also consists of diatomic molecules in its elemental form. However, it is not one of the least reactive elements; rather, it is one of the more reactive elements in Group 2.

Answer:
Explanation:
Fossil fuels are fuels that are formed by naturally processes leading to the formation of crude oil, coal and natural gas.
Scientists and engineers have used the energy from these fossil fuels to benefit the society by converting these fuels into consumable products for engines which are used for various daily life routine, such as transport (as in the case of the combustible engines in cars, trains, airplanes and ships), power generation (as in the case of gas turbines for power generation, petroleum or diesel for the engines of power generators) and even for home use in food processing (as in the case of cooking gas).
The chemical reaction mostly involved in this process especially in the case of engines is combustion reaction. Combustion reaction is an exothermic reaction in which an organic substance is burnt in excess oxygen to produce carbon dioxide. The energy conserved in this reaction (combustion reaction) is from stored potential energy (in the form of chemical energy) to thermal energy (which is the heat released when the hydrocarbon is burnt).
As mentioned earlier, one of the methods of using fossil fuels for energy is it's use in power generation by power generating sets (generators) and gas turbines. One advantage of using fossil fuel products for power generation is that it is cheaper than it's alternatives (such as solar power generation). However, one disadvantage of using fossil fuel products for power generation is that they release toxic gases/chemicals (such as carbon monoxide, CO, nitrogen oxides, NO and NO₂) into the atmosphere.
Final answer:
The energy in fossil fuels is harnessed and used mostly through the process of combustion which provides a high energy output but contributes negatively to the environment by increasing carbon dioxide levels.
Explanation:
Scientists and engineers harness and use energy in fossil fuels like coal, petroleum, and natural gas to benefit society in a number of ways, primarily through combustion. The combustion process is a chemical reaction whereby energy is released by burning these fuels amidst oxygen. This results in heat and energy, which is then converted to electricity and used for transportation, industrial production, and home heating purposes.
A common method is to burn these fuels, which in turn powers steam-driven turbines to produce electricity. The energy from the combustion of the fuels is transferred into mechanical work which is then converted into electrical energy. This process points to the principal of energy conservation which states that energy is neither created nor destroyed, but merely transformed from one form to another.
This method, however, has its pros and cons. On the positive side, fossil fuels are comparatively easy to extract, abundant, and provide a high energy output. But on the flip side, burning fossil fuels leads to environmental degradation by releasing carbon dioxide and contributing to global warming. Also, these fuels are non-renewable, and the resources are limited.

Answer: The reaction is exothermic. The value of q is -542 kJ.
Explanation:
Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and for the reaction comes out to be positive.
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and for the reaction comes out to be negative.
Thus evolves heat , it is exothermic in nature. The value of q is -542kJ.
