Calculate the specific heat capacity of a new alloy if a 15.4 g sample absorbs 297 Joules when it is heated from 5.0 °C to 20.7 °C. The key assumes you are giving your answer in Joules/g°C and rounding to 2 or 3 sig figs
Answer: The specific heat of alloy is [tex]1.23J/g^0C[/tex]
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
[tex]Q=m\times c\times \Delta T[/tex]
Q = Heat absorbed = 297 J
m= mass of substance = 15.4 g
c = specific heat capacity = ?
Initial temperature = [tex]T_i[/tex] = 5.0°C
Final temperature = [tex]T_f[/tex] =20.7°C
Change in temperature ,[tex]\Delta T=T_f-T_i=(20.7-5.0)^0C=15.7^0C[/tex]
Putting in the values, we get:
[tex]297J=15.4g\times c\times 15.7^0C[/tex]
[tex]c=1.23J/g^0C[/tex]
The specific heat of alloy is [tex]1.23J/g^0C[/tex]
The specific heat capacity of the new alloy is approximately 1.22 J/g°C.
Calculating Specific Heat Capacity:
To calculate the specific heat capacity of a new alloy, we use the formula:
q = mcΔTWhere:
q = heat absorbed (297 Joules)m = mass (15.4 g)c = specific heat capacity (J/g°C)ΔT = change in temperature (20.7 °C - 5.0 °C) = 15.7 °CRearranging the formula to solve for c:
[tex]c = \frac{q}{m\Delta T} = \frac{297\ J}{15.4 g \times 15.7 ^\circ C} \approx 1.22 J/g^\circ C[/tex]Therefore, the specific heat capacity of the alloy is approximately 1.22 J/g°C.

how to find final temperature
Answer:
to Calculate the final temperature of the water mixture using the equation T(final) = (m1_T1 + m2_T2) / (m1 + m2), where m1 and m2 are the weights of the water in the first and second containers, T1 is the temperature of the water in the first container and T2 is the temperature of the water in the second container.
To find the final temperature, use the reciprocal form of Charles's law to relate the initial and final temperatures and volumes of a gas.
Explanation:In order to find the final temperature, we can use the reciprocal form of Charles's law, which relates the initial and final temperatures and volumes of a gas. The equation is T1/V1 = T2/V2, where T1 and V1 are the initial temperature and volume, and T2 and V2 are the final temperature and volume. By rearranging the equation, we can solve for the final temperature:
T2 = (T1 * V2) / V1
Example: If the initial temperature is 20°C, the initial volume is 2 liters, and the final volume is 3 liters, we can substitute these values into the equation to find the final temperature:
T2 = (20 * 3) / 2 = 30°C

Final answer:
After 7 half-lives, approximately 2.15 grams of carbon-14 will remain from the original 550-gram sample.
Explanation:
The question asks how much remains after 7 half-lives of a 550-gram sample of carbon-14. To solve this, we need to understand that each half-life reduces the amount of carbon-14 by half. So after the first half-life, we have 275 grams left, after the second half-life, we have 137.5 grams left, and so on. After 7 half-lives, we will have:
275 grams / 2 = 137.5 grams137.5 grams / 2 = 68.75 grams68.75 grams / 2 = 34.375 grams34.375 grams / 2 = 17.1875 grams17.1875 grams / 2 = 8.59375 grams8.59375 grams / 2 = 4.296875 grams4.296875 grams / 2 = 2.1484375 gramsSo, after 7 half-lives, we will have approximately 2.15 grams of carbon-14 remaining from the original 550-gram sample.

A bag of potato chips is sealed in a factory near sea level. The atmospheric pressure at the factory is
0.82 millimeters of mercury (mm Hg). The pressure inside the bag is the same. What is the pressure
inside the bag of potato chips in Pascal's (Pa)?
Answer: The pressure inside the bag of potato chips in Pascal's is 109
Explanation:
Pressure of the gas is defined as the force exerted by the particles on the walls of the container. S.I unit of pressure is pascal.
Thus units of pressure can be mm Hg or atmosphere or bar or Pascal.
Given : Pressure inside the bag is the same as atmospheric pressure at the factory = 0.82 mmHg
Pressure 760 mm Hg = 101325 Pa
0.82 mm Hg = [tex]\frac{101325}{760}\times 0.82=109Pa[/tex]
Thus the pressure inside the bag of potato chips in Pascal's is 109
Final answer:
The pressure inside the bag of potato chips, sealed at 0.82 mm Hg, is equivalent to 109.324 Pascals (Pa) when converted using the factor 1 mm Hg = 133.322 Pa.
Explanation:
The pressure inside a bag of potato chips, if sealed at 0.82 mm Hg near sea level, can be converted to Pascals (Pa). As the conversion factor between mm Hg and Pa is 1 mm Hg = 133.322 Pa, we simply multiply the given pressure in mm Hg by this factor to obtain the pressure in Pascals.
To calculate the pressure in Pascals:
Multiply the pressure in mm Hg by 133.322 Pa/mm Hg.
So, the pressure inside the bag in pascals is:
Pressure in Pa = 0.82 mm Hg × 133.322 Pa/mm Hg
Pressure in Pa = 109.324 Pa
Therefore, the pressure inside the bag of potato chips is 109.324 Pascals (Pa).

Evaporation of alcohol from skin: liquid C3H8O+5.2 kJ 》 vaporized C3H8O. Burning of propane ina gas grill: C3H8+5O2 》 3CO2+4H2O+1652 kJ. Oxidation of iron to form rust: 4Fe+3O2》2Fe2O3+2221 kJ.
1. Endothermic reaction
2. Exothermic reaction
3. Exothermic reaction
Explanation:
1. Evaporation of alcohol from the skin, here the heat is absorbed by the alcohol so that it gets evaporated from the skin and it is an endothermic process. As the reaction says that, the energy is added to the system, so it is endothermic.
C₃H₈O + 5.2 kJ → C₃H₈O(g)
2. Burning of propane in a gas grill:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O + 1652 kJ.
Here energy is released or given out which is termed as exothermic reaction.
3. Oxidation of iron to form rust:
4 Fe + 3O₂ → 2 Fe₂O₃ + 2221 kJ.
Here also energy is released along with the products, so it is termed as exothermic reaction.
Whenever energy is absorbed, the reaction is endothermic in contrast if the energy is released then the reaction is exothermic.

carrying capacity is the maximum population that a given area can support.
am I right???
There will be change in the population of a species everyday. The carrying capacity is the maximum population that a given area can support. Thus the given statement is right.
What is carrying capacity?The carrying capacity is defined as the maximum population, density or biomass that a specific area can support sustainably. This likely changes over time and also depends on many environmental factors, presence of predators, etc.
It is the carrying capacity which denotes the point where the population cannot grow further theoretically and it is not growing any larger. It can be increased by supplying greater amount of food, decreasing predation, raising the amount of habitat, etc.
It can be decreased by increasing predation, decreasing the amount of habitat, etc. A constant K is used to represent the carrying capacity. It is due to this the population is found to be in a stable state.
Thus carrying capacity is the maximum population that a given area can sustain.

Answer : The spectator ions are [tex]Ba^{2+}[/tex] and [tex]CrO_4^{2-}[/tex]
Explanation:
Neutralization is a chemical reaction in which an acid and a base reacts to form salt and water.
Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.
The given chemical equation is:
