How insoluble impurities removed during recrystallization?
Insoluble impurities are removed during recrystallization by filtration. After dissolving the mixture in a hot solvent and allowing it to cool, the desired compound forms crystals while the insoluble impurities remain suspended in the solution. The crystals are then collected through filtration, separating them from the impurities.
What is the substance which reacts with unwanted impurities in ores to form a fusible mass which can easily be removed?
The substance that reacts with unwanted impurities in ores to form a fusible mass is called a flux. Fluxes are added during the smelting process to help separate the impurities from the desired metal, forming a slag that can be easily removed.
Why slag is produced in metal extraction?
Slag is produced during metal extraction as a byproduct of the reaction between impurities in the ore and the flux added to extract the desired metal. The slag, which consists of non-metallic compounds, forms from the impurities that are removed during the smelting process. It helps to separate the impurities from the metal being extracted.
What is it called when alum is added to water and forms sticky globs?
This is called flocculation. When alum is added to water, it reacts with impurities and causes them to clump together, forming sticky globs that can be easily removed.
What is a furnace for refining gold?
A furnace for refining gold is used to melt and separate impurities from gold ore, resulting in pure gold. This process involves heating the gold ore to high temperatures to melt it, while impurities separate and are removed as slag. The pure gold is then cast into bars or other forms for further processing.

Relation between Dew point temperature and pressure?
Dew point temperature is the temperature at which air becomes saturated with moisture and dew forms. As pressure increases, the air can hold more moisture before reaching saturation, leading to a higher dew point temperature. Conversely, a decrease in pressure lowers the air's capacity to hold moisture, resulting in a lower dew point temperature.
When the pressure in hurricane gets lower or higher what does the wind do?
The lower the barometric pressure is in a hurricane, the stronger the wind will be. Hurricanes form over warm ocean water and the lower the pressure is, the more moisture that will be attracted from the water. This warm moisture rises up and forms into clouds and wind, so the more moisture is rising, the stronger the winds will be. If the barometric pressure is high, the moisture can't move up and form clouds and wind.
How come when you roll a bottle and create pressure when the cap is released a cloud forms in the bottle?
Because the carbon dioxide is dissolved under pressure. When the cap is removed the pressure decreases , thus removing any gas that is dissolved under pressure.

What is the term that describes all forms of moisture leaving the atmosphere?
The term that describes all forms of moisture leaving the atmosphere is "precipitation." This includes rain, snow, sleet, and hail.
How do things rust and what factors contribute to the process of rusting?
Rust forms when iron or steel reacts with oxygen and water, causing a chemical reaction called oxidation. Factors that contribute to rusting include exposure to moisture, salt, and acids, as well as high temperatures and the presence of impurities in the metal.
What happens before it snow?
Before it snows, the moisture in the air condenses and forms clouds. As the temperature drops, the moisture in the clouds freezes and falls to the ground as snow when the conditions are right. This process is part of the water cycle and can be influenced by factors such as temperature, humidity, and air pressure.
What is the relative humidity when dew forms?
The relative humidity when dew forms is 100%. Dew forms when the air temperature cools down to the point where it can no longer hold all of its moisture, causing the excess moisture to condense and form droplets on surfaces.
