Answer:
Below are some general properties of these (HCl and H2SO4) solutions, and their common behavior in terms of the species present.
Explanation:
1) Aqueous solutions of these acids have a sour taste. i.e they can destroy body tissue and materials.
2) Both acids react with active metals and release hydrogen gas, H2.
Recall, in terms of an activity series. Metals above hydrogen in the series undergo displacement reactions with these acids. For example
2Na + 2HCl ------- 2NaCl + H2
and 2Na + H2SO4 ------- Na2SO4 + H2
3) The acids will react with bases to produce salts and water. These are neutralization reaction
s and the products are water and an ionic compound called a salt. For example
NaOH + HCl --------- NaCl + H2O
2NaOH + H2SO4 ---------- Na2SO4 + 2H2O
A. represents a situation in which the person is not handling frustration well. In the other situations, the people found they weren't doing as well as they had hoped and so they actively found ways to maneuver around this to improve their lives. Leslie gave up her job simply the move back with her parents with no indication that she would be able to support herself until she got the job she wanted. It's important to keep a source on income while chasing down a dream job.
Hope this helps! :)
When electrons are removed from the outermost shell of calcium atom, its atom becomes positively charged, with a charge of plus one.
When an electron is added to an atom, the atom becomes negatively charged, with a charge of minus one.
When these atoms become positively or negatively charged, they are known as ions. Positively charged ions are called cations and negatively charged ions are called anions.
Calcium is identified as one of the cations because it is positively charged when its electrons are removed from its outermost shell.
Density=mass/volume
density=2/8
density=0.25g/ml
Answer:
The over all charge on atom will be +2.
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.
For example
X is the element having 12 protons 10 electrons and 14 neutrons.
The number of protons and electrons are not equal which means two electrons are lose by the given atom and it is present in the form of cation.
The over all charge on atom will be +2.
