Answer 1

The phase of water at 0.5 atm and 100°C is gaseous phase.

What is water phase?

Water exists in three different phases such as liquid, gas, and solid.

The phase of the given water can be determined using phase diagram at standard temperature and pressure as shown in the image uploaded.

At 0.5 atm and 100 °C, the water is still in vapour or gaseous phase.

Thus, the phase of water at 0.5 atm and 100°C is gaseous phase.

Answers

It can be said that water will take more heat to raise its temperature by 1°C than copper. Details about specific heat can be found below.

What is specific heat capacity?

Specific heat capacity of a substance can be defined as the amount of heat (J) absorbed per unit mass (kg) of the material when its temperature increases 1 K or 1 °C.

According to this question, water has a specific heat of 4.184 J/g°C while Copper metal has a specific heat of 0.385 J/g°C. This shows that water has a higher specific heat.

Therefore, it can be said that water will take more heat to raise its temperature by 1°C than copper metal.

The enthalpy change of the given reaction is negative, so the reaction is an exothermic reaction.

What is enthalpy change of a reaction?

Enthalpy change of a reaction is the energy changes that occur when reactant molecules form products.

Enthalpy is the heat content of a substance.

When enthalpy change is positive, the heat content of the product is greater than that of the reactant and the reaction is an endothermic reaction.

Whereas, when enthalpy change is negative, the heat content of the reactant is greater than that of the product and the reaction is an exothermic reaction.

Therefore, since the enthalpy change of the given reaction is negative, the reaction is an exothermic reaction.

The densities of copper, silver, iron, and magnesium are in that order. You are given grams of each metal. Which one has the largest volume

Answers

Density is the ratio of mass to volume. The substance with the lowest density has the largest volume. The volume of magnesium will be the largest.

What is density?

Density is the mass per volume of the substance. It is denoted by the Latin letter rho (ρ) or D. It is the division of the mass in kilograms to the volume in cubic meters.

The relation of the density is inversely proportional to the volume and when the order is given in increasing order of density then magnesium will have the largest volume as it has the least density.

Therefore, magnesium has the largest volume.

How many kilojoules of heat are produced when 34.0 g of Fe2O3 reacts with an excess of CO according to the following reaction? Fe2O3 + 3 CO 2 Fe + 3 CO2 ΔH = -26.3 kJ

Answers

The heat produced when iron oxide reacts with carbon monoxide is -23.47 kJ/mol.

What is the enthalpy of reaction?

The standard enthalpy of the reaction is given by the enthalpy of formation of the products and the reactants. The reactants and the products of the reaction are:

Fe₂O₃ (s) + 3CO (g) → 2Fe(s) + 3CO₂ (g)

We know,

The standard enthalpy of formation of iron oxide = −825.50 kJ/mol

The standard enthalpy of formation of carbon monoxide = −110.53 kJ/mol

The standard enthalpy of formation of carbon dioxide = −393.52 kJ/mol

The standard enthalpy of reaction is calculated as:

[tex]\rm \Delta H_{rxn}[/tex] = [2(0) + 3(−393.52)] - [1(-825.50) + 3(-110.53)]

= (0−1180.56+825.50+331.59)

= −23.47 kJ/mol

Therefore, −23.47 kJ/mol is produced.

The SA would often use violence to break-up political meetings of opposing parties, such as the Communist Party. When elections were held, the SA would be out in force encouraging, i.e. frequently threatening citizens to vote for the Nazis. After 1933, the SA became too powerful a force of its own; Hitler recognized that, if Germany were to go to war, it would need the support of the traditional German military machine, i.e. support of the elite General Staff officers, many of whom were soldiers in the first World War, many who were from wealthy, land owning families, many who were sympathetic to the concept of having and needing a strong leader and a strong military, many who were, at heart, suspicious of a democracy, such as the German Weimar Republic, established as part of the Versailles Peace Treaty ending World War 1. The SA was forced to dissolve about 1934 and most of its members were integrated into the German armed forces. The SS, Hitlers elite military force was established to raise a generation of specially trained men who would follow orders without question. They participated, for example, as the Einsatzgruppen (Special Forces) and were responsible for conducting the mass executions in front of open pit grave sites (usually dug by the victims themselves) of thousands of innocent, Jewish citizens and political dissidents. Especially in the Soviet Union. Many were concentration camp guards or, as Rudolf Hoess at Auschwitz, rose to the ranks of a commandant of a concentration camp.The Main Office of the Order Police participated in roundups of Jews, guarding and shooting of Jews in ghettos, concentration camps and in towns occupied by the Germans.
