Usually calcium & magnesium ions.

What can you find dissolved in large quantities in hard water?
Calcium and magnesium are typically found dissolved in large quantities in hard water. These minerals can cause a buildup of scale in pipes, appliances, and fixtures over time.
Why is not hydrogen fueling all cars?
Hard to store large quantities of pure hydrogen, very volotile
What is the scum that on the surface of boiling hard water?
The scum on the surface of boiling hard water is usually a buildup of mineral deposits, such as calcium and magnesium. These minerals are present in high quantities in hard water and can form a layer of scum when the water is boiled, especially if there are impurities present.
Why do we use prefixes when explaining quantities?
We use prefixes to easily communicate and visualize very large or very small quantities. Prefixes like kilo-, mega-, giga- denote larger quantities, while milli-, micro-, nano- signify smaller quantities. This helps us avoid writing out a large number of zeros and makes it easier to understand the scale of the quantity being expressed.
What is something hard to find in a desert?
Water and food is hard for humans to find in a desert. Shelter from the sun is also hard to find.
Explain why soaps can be effective in hard water if relatively large quantities of soap are added to water?
A soap is an organic molecule that has a polar/hydrophilic end and a nonpolar/hydrophobic end. The polar end typically has a hydroxyl functional group, which acts like a weak acid in water. Hard water is water that has a relatively large solute load, typically calcium, magnesium and other metals. When you add a soap to hard water, the metal ions in the water attach themselves to the polar end and you get a precipitate of the salt form of the soap. This inactivates the soap. However, if you add enough soap, you will effectively "soften" the water by pulling enough metal ions out of solution to still have active soap molecules in the water.
What is the meaning of quahog?
An American market clam (Venus mercenaria). It is sold in large quantities, and is highly valued as food. Called also round clam, and hard clam.
Why is drinking ocean water harmful?
The science clearly points out that drinking sea water in large amounts is very unhealthy. Drinking small quantities without ever offsetting it with fresh water is also very clearly unhealthy. As most times it would be impossible, if not extremely hard, to supplement sea water with a proper amount of fresh water in a survival situation, it is best to avoid it altogether.
What is hard to find in a desert?
Water, Shelter, Food.
In which lands is water plentiful?

What is a hard thing to find in the desert?
