Students were investigating heat transfer by conduction and they set up the simple experiment you see here. They utilized three spoons made of different materials: the specific heat capacity of each material was recorded in the students' data table. Each spoon was placed in a pot of hot (90°C) water and a pat of butter was placed on the handle of each spoon. The butter melted first on the tin spoon and in about the same amount of time on the plastic and wood spoons. Based on the data table and the experimental results select ALL of the conclusions that are appropriate.
A) Conduction occurred more readily in the tin due to its lower specific heat
capacity
B) Heat transfer via conduction occurred from the hot water to the spoons
and then to the butter,
C) When in contact with hot water, there was no transfer of kinetic energy
through the wood or plastic
D) The atoms in the tin spoon vibrated and collided at a greater rate thon
those in the wood or plastic spoons
E) In all three cases energy s transferred from the faster moving hot water
molecules to the slower moving molecules in the spoon
Answers
Answer:
the Answer is A B D
Explanation:
the cunduction in the spoons are equal to all the following answers
Conduction occurred more readily in the tin due to its lower specific heat capacity, Heat transfer via conduction occurred from the hot water to the spoons and then to the butter, The atoms in the tin spoon vibrated and collided at a greater rate thon those in the wood or plastic spoons. Thus option A,B, D are correct.
What is specific heat ?
Specific heat can be measured as the quantity of heat required to increase the temperature of one gram of a substance by one degree Celsius.
The units of specific heat are represented as calories or joules per gram per Celsius degree such as the specific heat of water is 1 calorie per gram per Celsius degree
Specific heat capacity= Heat quantity/ mass × change in temperature.
If Q is the quantity of heat in joules, M is the mass of substance heated,
If ∆O is the change in temperature in Kelvin, Then Q= MC∆O, C is a constant called Specific heat capacity. Therefore, making C the subject of formula:
C= Q /M∆O
Thus option A,B, D are correct.

Answers
The enthalpy of this reaction is -296. 8 kJ/mol.
The equation of the reaction is;
S(s) + O2(g) -----> SO2(g)
Recall that the enthalpy of the reaction can be obtained from the formula;
ΔHrxn = ΔHf(products) - ΔHf(reactants)
We know that;
ΔHf S(s) = 0 KJ/mol
ΔHf O2(g) = 0 KJ/mol
ΔHf SO2(g) = -296. 8 kJ/mol
Hence;
ΔHrxn = -296. 8 kJ/mol - [0 KJ/mol + 0 KJ/mol]
ΔHrxn = -296. 8 kJ/mol

In one to two sentences, explain how to compare the strength of electrostatic forces between molecules in salt water to the strength of electrostatic forces between molecules in freshwater. Include a description of the data to be collected and how that data would allow one to draw conclusions about the relative strengths of the electrostatic forces in the two substances.
Answers
Answer:
-Salts are composed of ions that form a tightly packed and ordered network, which is called a crystal lattice, and it is held together by ionic bonds.
Explanation: salts are ionic compounds, which are composed by oppositely charged ions (cations and anions) which are bonded each other by ionic bonds, in an ordered arrangement, often a crystalline solid.
-When a salt is added to a polar solvent like water, the ions interact with the solvent molecules via ion-dipole forces, which overcome the forces originally holding the ions together.
Explanation: the molecules of a polar solvent are dipoles because they have dipolar momentum (a difference in charge due to a electronegativiy difference). When a salt is dissolved in a polar solvent, it dissociates in ions. So, the resulting interactions between these species are ion-dipole forces.
-The ions are then isolated and stabilized in solution via these interactions, and when this occurs for most of the salt compound, it is considered soluble in that solvent.
Explanation: the ions in solution are surrounded by solvent molecules which stabilizes them. A salt which is enterely dissolved in a solvent is soluble in that solvent.
-Due to the nature of the interaction between ions and solvent molecules, a concentration of ions can be dissolved higher in water than in alcohol.
Explanation: water molecules have unique properties that make water an universal solvent. Due to these properties and its polarity, water can dissolve larger quantities of salt than other polar solvents such as alcohol.
The electrostatic force in water without salt is stronger as compared to the water due to the presence of free electrons.
In water hydrogen bonding is present that is the only kind of electrostatic force present in the water. In water containing salt sodium and chloride ions are present which conduct strong electrostatic force. A static meter is ideal for measuring the of liquids. It measures the charge on the liquid. Hence, the electrostatic force in salt water is stronger as compared to the water due to the presence of free electrons.Learn more about electrostatic:

A sample of Ammonia gas at 650mmHg and 15 degree has a mass of 56.8g.calculate the volume occupied by the gas. Take N=14, H=1,R=8.3145jk.
Answers
Answer:
The first thing we have to do is change and state all the units so that we can use our ideal gas law equation ([tex]PV = nRT[/tex]).
650 mmHg is a pressure unit, we have to convert this to kiloPascals. We know that 760 mmHg gives us 101 kPa.
[tex]650 \ mmHg \ * \ \frac{101kPa}{760 mmHg} = 86 \ kPa[/tex]
P = 86kPa
T = 15°C + 273K = 288K
R (Gas constant) = 8.31 kj/mol
Molar mass of Ammonia ([tex]NH_{3}[/tex]) = (1 x 3) + (14) = 17g/mol
n (moles) = [tex]\frac{mass}{molar \ mass}[/tex] [tex]= \frac{56.8}{17} =[/tex] 3.34 mol
V = ?
Rearrange the equation to solve for Volume:
[tex]V = \frac{nRT}{P}[/tex]
Substitute the values inside:
V = [tex]\frac{(3.34)(8.31)(288)}{(86)} = 93 L (rounded)[/tex]
Therefore 93 L of volume is occupied by the ammonia gas.
