Answer:
1
Explanation:
The pH scale goes from 0 to 14. 0 is the most acidic and 14 is the most basic so the middle, 7, is neither acidic or basic. Anyway, thos most acidic rating is the lowest number, so here that's 1
Question: When an atom that has no charge loses two electrons, it becomes a:
A: positive ion.
B: negative ion.
C: positive isotope.
D: negative isotope.
Answer:
When an atom that has no change loses two electrons, it becomes "positive ion".
Explanation:
It is known that electrons hold a negative charge. So, when the negative charge that is electrons are taken out an atom then the number of electrons become less in number as compared to the number of protons. Hence, the atom attains a positive charge.An isotope is formed when an atom shows same number of protons and different number of neutrons. So, when an atom loses 2 electrons there will be no change in the number of neutrons. Therefore, an isotope will not form.Thus, it is concluded that when an atom with no charge loses two electrons, it becomes a positive ion.
The best answer is starch.
Starch is a type of carbohydrate.
Carbohydrates are made of simple sugars, namely glucose. A simple sugar is a single molecule of a sugar. A single sugar molecule is called a monomer.
Starch is made of many monomers or units of glucose linked together and is thus called a polysaccharide. When it is broken down, the result is its many glucose units are separated from each other by breaking the chemical bonds that hold them together, and are thus released as simple sugars.
The population will later, cease to exist.
Since the population is experiencing (about) the same rates of immigration and emigration, these 2 factors will not change anything.
A low birth rate and a high death rate means that more people are dying than being born.
Therefore the population will decrease until there is nobody and it will cease to exist.
