Response: The increase in temperature is 
Reasoning:
The amount of thermal energy needed to elevate the temperature of a given substance by one degree Celsius is referred to as the specific heat capacity.

Q = Heat gained by ice = 5280 J
m = mass of ice = 2.40 kg = 2400 g (1kg=1000g)
c = heat capacity of water = 
Initial temperature =
Final temperature =
Temperature change ,
Substituting the values, we obtain:


Therefore, the temperature increase is 
Answer: The overall width of a crystal measures 1.65 mm.
Explanation:
Horizontal distance separating the two molecules is 16.5 nm.
Width of the
molecules:

The overall width of a crystal measured in millimeters=
The overall width of a crystal is 1.65 mm.
The mixture’s density is 1.57 g/cm³.
Step 1: Determine the mass of the butter.

Step 2: Determine the mass of the sand.

Step 3: Determine the density of the mixture.
Total mass = 0.860 g + 2.28 g = 3.14 g.
Total volume = 1 cm³ + 1 cm³ = 2 cm³

Answer:
1. 192.0 g/mol.
2. 84.0 g/mol.
Explanation:
- The molar mass refers to the weight of all atoms combined in a molecule measured in grams per mole.
- To find a molecule's molar mass, we begin by looking up the atomic weights of the relevant elements from the periodic table. Next, we tally the atoms present and multiply that by their respective atomic weights.
1. Molar mass of citric acid (C₆H₈O₇):
Molar mass of C₆H₈O₇ = 6(atomic mass of C) + 8(atomic mass of H) + 7(atomic mass of O) = 6(12.0 g/mol) + 8(1.0 g/mol) + 7(16.0 g/mol) = 192.0 g/mol.
2. Molar mass of baking soda (NaHCO₃):
Molar mass of NaHCO₃ = (atomic mass of Na) + (atomic mass of H) + (atomic mass of C) + 3(atomic mass of O) = (23.0 g/mol) + (1.0 g/mol) + (12.0 g/mol) + 3(16.0 g/mol) = 84.0 g/mol.
Answer:
The work done in this process will be considered Negative.
Explanation:
The energy transferred by the system to the environment is negative
Therefore, if work is done on the system, it is labeled as positive. Conversely, when work is done by the system, it is regarded as negative.
In this scenario, the argon gas is expanding, and the work is exerted by the system into the surroundings (container), making the sign Negative.
Thus, the result for the work pertaining to this process will carry a Negative sign.
