1) amount of energy required to change 1 gram of material from the solid to the liquid state at its melting point - latent heat of fusion.

The temperature at which the phase transition occurs is the melting point or the freezing point.

2)  a measure of the kinetic energy of the particles of a substance - temperature.

Temperature is the intensity of heat present in a substance and a thermometer is a device that measures temperature or a temperature gradient.

3) the amount of energy required to change 1 gram of a substance 1°C - specific heat.

Heat capacity of a sample is expressed in units of thermal energy per degree temperature (J/K).

Heat capacity is often defined relative to a unit of mass (J/kg·K or J/g·K), prefixed with the term specific.

For example, specific heat capacity of water is 4.184 J/g·K (Cp(H₂O) = 4.184 J/g·K).

4) amount of energy required to change 1 gram of material from the liquid to the gaseous state at its boiling point - latent heat of vaporization.

For example, evaporization is phase change process in which the water changes from a liquid to a gas (water vapor). Solar radiation is the source of energy for evaporation.

5) the amount of heat energy required to raise the temperature of 1 gram of liquid water from 14.5°C to 15.5°C - calorie.

Calorie (cal), or small calorie, is the amount of energy needed to heat one gram of water by one degree Celsius.

One small calorie is approximately 4.2 joules.

A calorie is a unit of energy.

You are given sodium acetate, 1m hcl, nahco3 and na2co3. Determine which of these four you would need and then show calculations
valentina_108 [34]

solution:

the given compounds are sodium acetate, 1M HCL,NaHCO₃ and Na2CO₃

pH of the buffer solution is 4.7

the value of pKa of sodium bicarbonate is 6.37

the value of pKa of acetic acid is 4.7

calculate concentration of acetic acid by using the following forumula

pH=pKa+lag[salt]/[acid]

substitute the pH and Pka values in the formula.

4.7=4.7+log[salt]/[acid]

log[salt]/[acid]=0

thus, the concentration ratio of the salt and acid should be equal to each other.

Thus, concentration of sodium acetate is 0.05M

Concentration of sodium acetate= concentration of acid

= 0.05M

Volume of the buffer solution is 100mL

The buffer solution can be prepared as 0.05M of 50mL sodium acetate will react with 0.05M of 50mL of 0.05M of HCL.

The chemical equation for neutralization of the weak base with strong can be represented as show as

CH₃COONa+HCL-->CH₃COOH+NaCL

Indicate which reaction will occur faster. explain your reasoning. select the single best answer. solvolysis of 1−chloro−2,2−dim
Radda [10]
The tert-butyl chloride in ethanol would surely react faster than the solvolysis of 1-chloro-2,2-dimethyl propane. It is known that both reactions are under the SN2 category so it would be hard for these reactions to occur. However, SN1 reactions are possible because of the ethanol which is a polar solvent. Both would form carbocations but tert-butyl chloride forms a more stable carbocation while the 1-chloro-2,2-dimethyl propane forms a primary carbocation only.

7. Ionic bonds are at one end of the bond spectrum. What kinds of bonds are at the other end?
blondinia [14]

Answer:

non-polar covalent bonds

this is when the electronegativity difference between the two non-metal atoms is very little to cause a partial charge (delta positive and delta negative; δ+ and δ-) on the atoms

The spontaneous intermingling of atoms among different substances is accomplished by_____. active transport energy combustion di
elixir [45]

Answer- The intermingling of atoms takes place the help of diffusion.

Explanation- There are two areas one has a higher concentration and the other has a lower concentration and a substance moves from higher to lower and the process happening is called diffusion.

Combustion is heating up of the substance hence does not have any intermingling atoms and energy transport also does not have any atoms mingling together hence diffusion is the correct option.
