Answer:
Four or Five
Explanation:
The five phases of matter. There are four natural states of matter: Solids, liquids, gases and plasma. The fifth state is the man-made Bose-Einstein condensates
The answer is 35 grams.
When we mix salt and water, salt will dissolve. Still, it mass does not disappear, but remains intact. Mass cannot be destroyed. When salt is dissolved in the water, salt molecules are only re-positioned, but all the molecules are present as well as their mass. <span>So if you add 5 grams of salt in 30 grams of water, the resulting mass will be 5 + 30 grams, which is 35 grams. </span>
Molarity is the measure of a concentration of a certain chemical substance
Atoms in the same group (column) of the periodic table have similar properties. This is because all elements in the same group have the same amount of valence (outer) electrons.
So, any element directly above or below Calcium on the periodic table would have similar properties.
These would be Magnesium, Barium, Strontium, Radium, and Beryllium.
1) during daylight, especially around noon, the relatively high air **temperature** and low humidity caused high evaporation, extracting pore water from the beach and leaving the **salt** behind, thereby resulting in high salinity near the beach surface (intertidal zone)
2) • algae and other intertidal plants grow in the abundant sunlight and support an entire food chain of animals
• constant wave action supplies the tide pool with **nutrients** and oxygen
• food is abundant
• a varied substrate provides hiding places and surfaces to cling to
3) the intertidal zone is one of a number of **marine** biomes or habitats, including: estuary (spray zone), neritic (lower/shallow zone), surface (middle zone), deep zones (high zones)
