The right answer for the question that is being asked and shown above is that: "B 1.5 X 1-^-5 ppm." A 250-mL aqueous solution contains 1.56 mc025-1.jpg 10–5 g of methanol and has a density of 1.03 g/mL. The concentration in ppm is that <span>1.5 X 1-^-5 ppm</span>
air pollution would cause trees to die and animals to die . It would coaus most harm by killing everything on land and in the sea beacuse the animals that die might wash away in the ocean killing other animals slowly but surely. and it doesnt help there is soil erosion sooner rather that later it will turn into nothing.
Explanation:
Answer:
B)
Explanation:
Dalton was the first scientist to propose an atomic model. He said that each element is composed of extremely small particles called atoms, which are indivisible, atoms of a given element are identical, and atoms of different elements have different properties.
With the advance of the studies, it was proven that elements are composed of small particles, atoms and that the atoms of each element are identical, and have different properties from atoms of different elements.
But, now we know that the atom can be divisible: it's formed by electrons, protons, and neutrons. So only postulate <em>ii</em> is no longer considered valid.
Answer:
0
Explanation:
pure elements will always possess an oxidation number of 0, regardless of their charge.
