Answer: C the study of living things
Explanation:
Rocks are made of many different materials. Different types of rocks are made from different sediments. Depending on the sediment that the rock is made of depends on how strong the rock will be. There are six main types of sedimentary rocks. All of the rocks are different colors depending on the sediments it consist of.
Answer:
Filtration and evaporation
Explanation:
A mixture of sand, pink sugar and water can be separated by filtration and evaporation.
The pink sugar is already dissolved in the water but the sand remains undissolved in the water hence it can be filtered off. The filtrate now contains the sugar.
The sugar is obtained from the filtrate by evaporation of the solution to yield the solid pink sugar and steam which can be condensed again to give liquid water.
Answer:
Moles
Explanation:
Mole is used to describes the amount of matter. The one mole of every substance have different mass, because every matter has different mass. The one mole of substance is equal to the molar mass of that substance.
The molar mass of substance is the mass in gram in one mole and it is represented by g/mol.
For example:
The molar mass of oxygen is 16 g/mol. If we take 16 g of oxygen we would say we taken one mole of oxygen. If we take 32 g of oxygen than it is describe as two mole of oxygen.
Consider the following reaction:
2H₂ + O₂ → 2H₂O
In this reaction two mole of hydrogen gas combine with one mole of oxygen and produce two moles of water.
