Answer:
A major characteristic of mixtures is that the materials do not chemically combine
Explanation:
Mixtures can be divided into those that are evenly distributed (homogeneous) and those that aren't (heterogeneous)
Solubility of a compound in water can be referred to as the amount of the compound that can be dissolved in 1 L of the solvent (water) at any given temperature. Solubility of a compound can be expressed in the units of g/L or mg/L.
Given that the solubility of calcium carbonate in water = 14 mg/L
We have to calculate the volume of water that can dissolve 11 g of calcium carbonate.
Converting 11 g calcium carbonate to mg:
Volume of water that would dissolve 11000 mg calcium carbonate
= 
=785.7 L
Rounding the volume 785.7 L to two significant figures, we get 790 L water.
Therefore, we would need 790 L water to completely dissolve 11 g of calcium carbonate.
Consumption of the acidic and the basic is equal during human's life. For example, acidic ones add sourness to things we eat and what about basic - the taste is quite bitter that conidered to be less enjoyable. Every our dish consists of both listed elements but our bodies are already accustomed to this fact.
Hope that helps.
Answer:
Iron and vermiculite.
Explanation:
Iron and vermiculite are the solid substances used to make a hand warmer. Hand warmers contains iron, water, activated carbon, vermiculite, cellulose, and salt. The high melting, boiling points, hard and brittle are the characteristics of an ionic solid used in hand warmer. Iron is the ionic solid which is used in the hand warmer. Once iron exposed to air, the iron oxidizes and releases heat in the process.
The name that I found is Silicate
