Answer:
This group metal is Barium (Ba)
Explanation:
Metals generally loses valence electrons easily. Barium is a chemical-like, but more volatile, metallic component of calcium. It is a smooth, silvery metal, and due to the formation of barium oxide (BaO), this quickly turns a black color when sliced. It is also extremely liquid and alcohol reactive.
Answer:
1. succession
2. exponential growth
Explanation:
1. Ecological succession is how biological communities change, re-structure and re-assemble over time, usually after some change or disturbance, or occupation of a new habitat. Ecological succession usually starts with a very simplistic structure, with some founder species that begin, then over time (it could be 10 years, it could be millions of years), the population grows in complexity and develops.
2. Exponential growth refers to a specific pattern of growth that occurs when resources are not limited. This pattern is when the size of the population is always increasing at a greater and greater rate. The best example is in bacteria. When they are in favourable conditions, the cells keep dividing, doubling every day, leading to exponential growth until nutrients become limited and growth slows.
Answer is: Na₂SO₄ (sodium sulfate).
The solubility of sodium sulfate increases up to 32.38°C and than decreases at higher temperatures, the solubility becomes almost independent of temperature.
At 32.38°C it releases of crystal water and melting of the hydrated salt.
Sodium sulfate is the white, inorganic compound.
Sodium sulfate is highly soluble in water.
