30.4 is the answer
<span> composition is: 58.8 0/0 C, 9.9 0/0 H, and 31.3 0/0 </span>O<span>. Ifit's molecular mass is 306 ... composition of the </span>compound<span> is </span>30.4<span>% </span>
Convert Mg to grams
1g =1000mg what about 3.91 Mg
= 3.91mg x 1g/1000mg= 3.91 x10^-3 g
moles= mass/molar mass
that is 3.91 x10^-3g /99 g/mol=3.95 x10^-5moles
concentration= moles / vol in liters
that is 3.95 x10^-5/100 x1000= 3.94 x10^-4M
equation for dissociation of CUCl= CUCl----> CU^+ +Cl^-
Ksp=(CU+)(CI-)
that is (3.95 x10^-4)(3.95 x10^-4)
Ksp= 1.56 x10^-7
Answer:
The White Dwarfs are very hot stars, which are small in size and relatively dim. They are found in the lower left of the H-R Diagram. The Main Sequence is a band of stars, which includes most of the stars, like our Sun. These are usually smaller stars, often dwarf stars.

Answer:
Double displacement chemical reaction.
Explanation:
Hello,
In this case, for the given reaction we firstly balance it:
Then, since the lithium and potassium cations are being exchanged to each other from bromide and carbonate, we are talking about a double displacement chemical reaction.
Best regards.
Explanation:
Protons are the positively charged particles found in an atom.
- A proton is found within the nucleus of an atom.
- Together with the neutron, they make up the nuclear region of an atom.
Protons and neutrons constitutes the bulk mass of the atom.
The mass of a proton is 1.67 x 10⁻²⁷kg
The proton have the same mass as neutrons.
Compared to electrons, it is 1840 times the mass of an electron.
