Answer:

cannot be used to produce energy in reactors.  

Explanation:

Currently, there is no reactor that can allow the use of nuclear fusion, although nuclear plants use nuclear fission reactors.

Nuclear fusion happens when thousands of atoms collide with each other when they are in the midst of extreme conditions of literature and pressure. This collision causes the atoms to fuse, creating another element. The process releases amounts of light and heat, promoting a high release of energy. This whole process occurs without the release of CO2 into the atmosphere, without the release of toxic waste and without the risk of explosions, which makes nuclear plants have a strong interest in building a reactor to use this type of energy. For this reason, scientists from different countries have collaborated with each other on a project called Iter, which seeks to build a reactor and achieve the first reaction in 2025.

22-yes, they belong to the same group
23- they are metals
24-Atoms of group 1 elements all have one electron in their outer shell. This means Na and K have the same valence electrons.
25-Metals are solids at room temperature, therefore Na and K are solid.
26- mass number=A=235
Protons=z=92
Neutrons=mass number-protons
Neutrons=A-Z
Neutrons=235-92
Neutrons=143

Determine the heat of reaction for the process TiO2(s) + 4HCl(g) TiCl4(l) + 2H2(g) + O2(g) using the information given below: Ti
Aleks [24]

Answer : The heat of reaction for the process is, 1374.7 kJ

Explanation :

According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.

According to this law, the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.

The main chemical reaction is,

TiO_2(s)+4HCl(g)\rightarrow TiCl_4(l)+2H_2(g)+O_2(g)    \Delta H_{rxn}=?

The intermediate balanced chemical reaction will be,

(1) Ti(s)+O_2(g)\rightarrow TiO_2(s)     \Delta H_1=-939.7kJ

(2) 2HCl(g)\rightarrow H_2(g)+Cl_2(g)    \Delta H_2=-184.6kJ

(3) Ti(s)+2Cl_2(g)\rightarrow TiCl_4(l)    \Delta H_3=-804.2kJ

We reversing reaction 1, 3 and multiplying reaction 2 by 2 and then adding all the equations, we get :

(1) TiO_2(s)\rightarrow Ti(s)+O_2(g)     \Delta H_1=939.7kJ

(2) 4HCl(g)\rightarrow 2H_2(g)+2Cl_2(g)    \Delta H_2=2\times (-184.6kJ)=-369.2kJ

(3) TiCl_4(l)\rightarrow Ti(s)+2Cl_2(g)    \Delta H_3=804.2kJ

The expression for heat of reaction for the process is:

\Delta H_{rxn}=\Delta H_1+\Delta H_2+\Delta H_3

\Delta H_{rxn}=(939.7kJ)+(-369.2kJ)+(804.2kJ)

\Delta H_{rxn}=1374.7kJ

Therefore, the heat of reaction for the process is, 1374.7 kJ

Carbon monoxide is a gas at 0 °c and a pressure of 1.58 × 105 pa. it is a diatomic gas, each of its molecules consisting of one
Hoochie [10]

Given temperature = 0^{0}C = (0^{0} + 273 )K  = 273 K

Pressure = 1.58 ×10^{5} Pa ×\frac{1 atm}{1.01325*10^{5}Pa}

= 1.56 atm

Density =\frac{PM}{RT}

ρ = \frac{(1.56 atm)(28.01 g/mol)}{(0.08206 L.atm/mol.K)(273 K)}

= 1.95 g/L
