Hello, Ginamuhs2!
The oxidizing agent in 2H2S + 3O2 → 2SO2 + 2H2O is the oxygen.
I hope this helps;)
Answer:
The substance has a density of 2.636 grams per mililiter.
Explanation:
We must remember that density (), measured in grams per mililiters, is the mass of the substance (), measured in grams, divided by its volume (), measured in mililiters. That is:
In addition, a kilogram equals 1000 grams and a liter equals 1000 mililiters. If we know that and , then:
The substance has a density of 2.636 grams per mililiter.
B. c-14
C. u-235
D. u-238
Answer:
C. U-235
Explanation:
A fission reaction is one in which an unstable radioisotope breaks down into smaller nuclei when bombarded with energetic particles.
The highly unstable isotope that is often used in fission reactions is U-235. When bombarded with neutrons that atom breaks down to form krypton and barium along with the release of a large amount of energy. The reaction is given as:
₉₂U²³⁵ + ₀n¹ → ₃₆Kr⁸⁹ + ₅₆Ba¹⁴⁴ + 3₀n¹ + 210 Mev energy
Answer : In an aqueous solution, a chloride ion is attracted to the hydrogen end of the water molecule.
Explanation :
The meaning of aqueous solution is the solution in which the solvent is water. In water molecule , oxygen atom is more electronegative than the hydrogen atom. That means, the hydrogen in the water molecule has partial positive charge and oxygen has partial negative charge.
As the chloride ion have the (-1) negative charge. So, it will be attracted towards the positive charge that is hydrogen end of the water molecule because opposite charges attract to each other.
Hence, in an aqueous solution, a chloride ion is attracted to the hydrogen end of the water molecule.
(B)The positive charge on the nucleus of the ion is two units greater than the nuclear charge on the atom.
(C)The ion has two more protons than the atom.
(D)The ion will react more readily with free Cl₂.
(E)The ion has two more planetary electrons than the atom.
Can anyone explain this one?
The amino acids are the molecules where we can found the carboxyl group (-), amino group (-), hydrogen atom (H) and a residual R-group. On the structure of the residual R-group the name of the amino acid depends. Like if R is hydrogen (H) the amino acid is alanine; If R- group is a phenyl group i.e. , the compound is called phenyl alanine. The structure of the general amino acid skeleton can be shown as-
