The element in question is Sodium

An atomic mass unit is defined as 1/12 th of the mass of carbon-12 atom.

The mass of an atom is mainly due to its protons and neutrons in the nucleus.

Weight of a proton is 1.6 x 10^-27 kg

Weight of a neutron is 1.6 x 10^-27kg

However weight of an electron is 9 x 10^-31kg and hence is negligible in calculation of amu

It is given that weight is 23 AMU and number of protons is 11

The protons in a nucleus also act as atomic number of the periodic table

Proton number 11 is the atomic number of Sodium

Hence the element is Sodium

When aqueous solutions of sodium chloride and silver (I) acetate combine, what are the products?
lesya692 [45]

Answer: The products are sodium acetate (CH_3COONa) and solid silver chloride (AgCl)

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

The reaction of  aqueous solutions of sodium chloride and silver (I) acetate is :

NaCl(aq)+CH_3COOAg(aq)\rightarrow CH_3COONa(aq)+AgCl(s)

Thus the products are aqueous sodium acetate (CH_3COONa) and solid silver chloride (AgCl)

How do you test pH levels in bottled water?
dimaraw [331]
You can use a universal indicator. The color of the universal indicator before contact with other chemicals is green, which is the pH of 7. We know that bottled water is pH 7. So when we put a few drops of universal indicator, the color would be green indicating neutral pH.
