Answer:
A. steel spoon
Explanation:
A steel spoon will get hot the quickest from the different given spoon. This is because steel is predominantly made up of a metal which shows metallic properties such as heat conduction.
- Metals have low specific heat capacity which is the amount of head needed to raise 1g of a substance by 1°C.
- By so doing, metals will conduct heat at a very fast rate.
- The delocalized electron around the central nucleus plays very important role.
Other properties originating from metallic bonds are ductility, malleability, luster etc.
Hello!
a gas thermometer measure temperature by measuring the pressure of a gas inside the fixed volume container a thermometer reads a pressure of 248 torr at 0 degrees Celsius what is the temperature when the thermometer reads a pressure of 345 torr
We have the following information:
P1 (initial pressure) = 248 torr
T1 (initial temperature) = 0 ºC (in Kelvin)
TK = TºC + 273.15 → TK = 0 + 273.15 → T1 (initial temperature) = 273.15 K
P2 (final pressure) = 345 torr
T2 (final temperature) = ? (in Kelvin)
According to the Law of Charles and Gay-Lussac in the study of gases, we have an isochoric (or isovolumetric) transformation when its volume remains constant or equal, then we will have the following formula:
If you want the solution in Celsius Temperature, we have:
TC = TK - 273.15
TC = 380 - 273.15
TC = 106.85 → Temperature = 106.85 ºC

Answer:
1.4 × 10^-4.
Explanation:
C3H6O3 + H2O <======> C3H5O3^- + H3O^+ ------------------------------------------(1).
So, from the question above we are given the following parameters or data which is going to help in solving this particular Question/problem;
=>concentration of the solution of lactic acid (CH3CH(OH)C00H) = 0.1 M and pH = 2.44.
Therefore, the concentration of the hydrogen ion[H^+} can be determined from the pH formula given below;
pH = - log { H^+}.
2.44 = - log { H^+}.
Therefore, {H^+} = 0.0036 M.
From the equation (1) given above, we have that the ratio for the equilibrium reaction is 1 : 1 : 1 :1. Therefore, molarity of C3H5O3^- = 0.0036 M and the molarity of C3H6O3 =( 0.1 - 0.0036 M) = 0.0964 M at equilibrium.
Hence, ka = {C3H5O3^-} { H3O^+} /{C3H6O3} = ( 0.0036 M)^2 /(0.0964 M) = 1.4 × 10^-4.
Answer:
In chemistry, a single bond is a chemical bond between two atoms involving two valence electrons. That is, the atoms share one pair of electrons where the bond forms. Therefore, a single bond is a type of covalent bond.
