A solvent is something that can have something else dissolved within it and turn into a homogenous solution, while the solute is that something else that can be dissolved into the solvent. Usually, the solvent is found in greater amount because most (except for rare cases) solvents have a saturation point that is below the equal-mass point.
A crushed garlic will have a lot of flavor when placed in food due to the surface area that is in contact with the food. When we have a large piece of garlic, only the external part touches the food and its full capacity is not used. When we reduce the size of the year by crushing the internal parts that were not in contact with the food, now they will be, in addition, liquids are also released due to the pressure exerted on the garlic and these liquids mix more easily with the food and they give it more flavor. For better understanding we can see the following figure:
Simply to understand it, in the figure, there is a clove of whole garlic represented by the rectangle that will have a height of 3 and a width of 1, the units do not matter in this case. The area that is in contact will be equal to 8, but if we divide the garlic into three equal parts, it will have a contact area greater than 12. Therefore, the more we divide the garlic, the more area it will be in contact with the food and will give it more flavor.
Answer: A. An early form of chemistry that people used to try to turn metal
into gold.
Explanation:
Alchemy is indeed an early form of chemistry in which people try to turn metal into gold.
Answer:
D) 174 g/mol
Explanation:
Step 1: Given and required data
- Density of the gas (ρ): 7.10 g/L
- Ideal gas constant (R): 0.0821 atm.L/mol.K
Step 2: Convert "T" to Kelvin
We will use the following expression.
K = °C + 273.15
K = 25.0°C + 273.15
K = 298.2 K
Step 3: Calculate the molecular weight (M) of the gas
We will use the following expression derived from the ideal gas equation.
ρ = P × M / R × T
M = ρ × R × T / P
M = 7.10 g/L × (0.0821 atm.L/mol.K) × 298.2 K / 1.00 atm
M = 174 g/mol
Generally, a liquid freezes exothermally on cooling and a crystal melts endothermally on heating.
The 6 phase changes are vaporization, condensation, freezing, melting, sublimation, and deposition
