This question is incomplete, the complete question is;

A 1.00 g sample of NH4NO3 is decomposedin a bomb calorimeter. The temperature increases by 6.12°C. What is the molar heat of decomposition for ammonium nitrate?

Molar mass, NH4NO3 80.0 g/mol

Calorimeter Constant   1.23 kJ/°C

Answer:

the molar heat of decomposition for ammonium nitrate is - 602.4 kJ/mol

Explanation:

Given that;

change in temperature ΔT = 6.12 °C

Calorimeter Constant C = 1.23 kJ/°C

Molar mass, NH4NO3 = 80.0 g/mol

we know that;

Heat gained by the calorimeter (Q1) = Heat lost by the decomposition of NH4NO3 (Q2)

Q1 = C × ΔT

Q1 = (1.23 kJ/K) × (6.12 K) = 7.53 kJ

Q value we get becomes negative since we are talking about reaction and not calorimeter

hence

Q1 = - 7.53 kJ

now

1 g NH4NO3 decomposed, - 7.53 kJ of heat is released

so if 80 g which is 1 mol NH4NO3 decompose, the heat will be;

(80 g/mol x -7.53 kJ) / 1 g = - 602.4 kJ/mol

Therefore the molar heat of decomposition for ammonium nitrate is - 602.4 kJ/mol

Answer:

4.67 atm

Explanation:

Step 1: Given data

Step 2: Convert "T" to Kelvin

We will use the following expression.

K = °C + 273.15

K = 27.0 °C + 273.15 = 300.2 K

Step 3: Calculate the moles of Ar

The molar mass of Ar is 39.94 g/mol.

4.73 g × 1 mol/39.94 g = 0.118 mol

Step 4: Calculate the partial pressure of Ar

We will use the ideal gas equation.

pAr × V = nAr × R × T

pAr = nAr × R × T / V

pAr = 0.118 mol × (0.0821 atm.L/mol.K) × 300.2 K / 2.00 L

pAr = 1.45 atm

Step 5: Determine the total pressure of the gaseous mixture

The total pressure of the gaseous mixture is equal to the sum of the partial pressures of the individual gases.

P = pAr + pHe = 1.45 atm + 3.22 atm = 4.67 atm

Answer:

2.9 g/cm³

Explanation:

From the question given above, the following data were obtained:

Mass = 236.376 g

Volume = 81.5 cm³

Density =?

Density can be defined as the mass of a substance per unit volume of the substance. It can be expressed mathematically as:

Density = mass /volume

With the above formula, we can obtain the density of the object as shown below:

Mass = 236.376 g

Volume = 81.5 cm³

Density =?

Density = mass /volume

Density = 236.376 / 81.5

Density = 2.9 g/cm³

Thus, the density of the object is 2.9 g/cm³

Answer:

0.491 atm

Explanation:

Initial volume V1 = 571.5 mL = 0.5715 L

Initial Pressure P1 = 0.944 atm

Initial Temperature T1 = 10 oC + 273 = 283 K (Converting to kelvin units)

Final Temperature T2 = 32 oC + 273 = 305K (Converting to kelvin units)

Final volume V2 = 1.183 L

Final Pressure P2 = ?

These parameters related by the combined gas law;

P1V1 / T1   = P2V2 / T2

Mke P2 subject of formular;

P2 = P1 V1 T2 / V2 T1

P2 = 0.944 * 0.5715 * 305  /  1.183 * 283

P2 = 0.491 atm

Answer:

All of the above

Explanation:

Answer:

Explanation:

What occurs here (the description in the question) is condensation. Condensation is the process in which water changes from it's gaseous state (steam) to it's liquid state. When the hot air leaves the oven, and it touches/ passes through the glasses of John (that is of a lower thermal energy), the hot air would lose some of it's thermal energy (due to the lower thermal energy of the glasses) and then transits back to liquid forming the visible fog steam on the glasses.

Answer:

The correct answer is Pu, 234.

Explanation:

In the given case, let us consider the reactant as X. Now the mass number (balanced) on both the sides will be,

Mass of X = Mass of Molybdenum + Mass of Tin + Mass of neutrons

M = 1 * 103 + 1 * 131 + 2 * 0

M = 234

Now the atomic number (balanced) on both the sides,

Atomic number of X = Atomic number of Molybdenum + Atomic number of Tin + Atomic number of neutrons

A = 1*42 + 1*50 + 2*1

A = 94

The atomic number 94 is for the element Plutonium, whose symbol is Pu. Thus, the reactant is 234-Pu.

Answer:

carbohydrates, lipids, proteins, and nucleic acids.

Explanation:

Carbohydrates serve several key functions in your body. They provide you with energy for daily tasks and are the primary fuel source for your brain's high energy demands.

The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes. Lipids have applications in the cosmetic and food industries as well as in nanotechnology.

Protein has many roles in your body. It helps repair and build your body's tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance.

The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.

Answer: synthesis, decomposition, single-displacement, double-displacement, combustion and acid-base reactions.

Explanation:

The correct statement : The atomic number of the radioactive nuclide is 90.

In the following element notation,

[tex]\large {{{A} \atop {Z}} \right X}[/tex]

X = symbol of elemental atom

A = mass number

   = number of protons + number of neutrons

Z = atomic number

   = number of protons = number of electrons, on neutral elements

The symbol for a radioactive nuclide :

[tex]\tt ^{234}_{90}Th[/tex]

atomic number  = 90

mass number  = 234

number of neutrons = 234-90=144

number of protons = atomic number = 90

Answer:

Sn(C2H3O2)2

Explanation:

C2H3O2 is Acetate

Sn is tin

Acetate has a -1 charge

In order for tin to have a +2 charge, we need two acetates

So we write it as (C2H3O2)2

You just leave Sn blank because of the roman numeral and since it is a transition metal.

So the answer is Sn(C2H3O2)2

Answer:

[tex]\boxed {\boxed {\sf Sn (C_2 H_3 O_2)_2}}[/tex]

Explanation:

First, find what tin and acetate is.

Next, find the charge on acetate, which is -1.

The Roman Numeral 2 in parentheses after tin (II), signifies that the tin has a charge of +2.

We need to balance the charges, so they will equal 0.

The best way to balance is by using 2 acetate molecules

If we want 2 acetate molecules, we must add a subscript of 2 after acetate.

Add the tin (Sn) in front

The formula for tin (II) acetate is Sn (C₂H₃O₂)₂

Answer:

2.64g of CO₂ are produced

Explanation:

The reaction of hexane with O₂ is:

C₆H₁₄ + 19/2O₂ → 6CO₂ + 7H₂O

To solve this question, we must convert each mass of reactant to moles in order to find limiting reactant and, with the chemical reaction we can find the moles of carbon dioxide produced and the maximum mass produced:

Moles hexane -Molar mass: 86.18g/mol-:

0.862g * (1mol / 86.18g) = 0.01 moles

Moles Oxygen -Molar mass: 32g/mol-:

5.1g * (1mol / 32g) = 0.16 moles

For a complete reaction of 0.01 moles of hexane there are required:

0.01moles hexane * (19/2 Oxygen / 1mol Hexane) = 0.095 moles oxygen

As there are 0.16moles, limiting reactant is hexane.

0.01 moles of hexane produce:

0.01 moles * (6 moles carbon dioxide / 1 mole hexane) = 0.06 moles of CO₂.

The mass is -Molar mass CO₂: 44g/mol-:

0.06 moles of CO₂ * (44g/mol) =

Answer:

the answer is hot,dense points; each smaller than an atom

Explanation:

the big bang theory was proposed to suggest the expansion of the universe by describing the origin of all components of the universe and its planetary bodies. its suggested that the whole universe was in a state of high temperature and highly dense points (which were smaller than atoms) but continuously expanded by cooling down which gave rise to the formation of subatomic particles, atoms, etc.

Answer:

160 g

Explanation:

The chemical equation is:

C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + 6H₂O(g)

According to the equation, 1 mol of glucose (C₆H₁₂O₆) reacts with 6 moles of O₂. We calculate the masses of the reactants from the molar masses of the chemical elements:

1 mol C₆H₁₂O₆ = (6 x 12 g/mol)+ (12 x 1 g/mol) + (6 x 16 g/mol) = 180 g

6 mol O₂ = 6 x (2 x 16 g/mol) = 6 x 32 g/mol = 192 g

So, 180 g of C₆H₁₂O₆ reacts with 192 g of O₂. The stoichiometric ratio is 192 g O₂/180 g C₆H₁₂O₆. To calculate the grams of O₂ needed to react with 150 g of C₆H₁₂O₆ we can simply multiply the stoichiometric ratio by the grams of C₆H₁₂O₆:

150 g C₆H₁₂O₆ x 192 g O₂/180 g C₆H₁₂O₆ = 160 g O₂

Therefore, 160 grams of O₂ are needed to fully react with 150 g of glucose.
