What is the percent of SO2 in H2SO4? Help Please

Chemistry
1 answer:
Yakvenalex [24]3 years ago
3 0

The percent of SO₂ in H₂SO₄ : 65.3%

<h3>Further explanation </h3>

Proust states the Comparative Law that compounds are formed from elements with the same Mass Comparison so that compounds have a fixed composition of elements

%Mass A in AxBy =  

\tt \dfrac{x.Ar~A}{MW~A_xB_y}\times 100\%  

For SO₂ in H₂SO₄ :

MW SO₂ = 32 + 2.16=64 g/mol

MW H₂SO₄ =2.1+32+4.16=98 g/mol

The percent of SO₂ :

\tt \dfrac{64}{98}\times 100\%=65.3\%

Write a summary of the science of muscle growth?
frez [133]

Answer:Muscle growth or “skeletal muscle hypertrophy,” as it's called at science parties) is the result of a complex process that adds more myosin “filaments” to each muscle fiber. This makes the “engine” of the cell bigger and stronger over time. ... This process is called muscle protein synthesis, or MPS. Skeletal muscle is composed of thread-like myofibrils and sarcomeres that form a muscle fiber and are the basic units of contraction. The 650 skeletal muscles in the human body contract when they receive signals from motor neurons, which are triggered from a part of the cell called the sarcoplasmic reticulum.

Two containers hold the same radioactive isotope. Container A contains 1000 atoms, and container B contains 500 atoms. which con
enyata [817]

Answer:

The rate of decay of atoms in container A is greater than the rate of decay of atoms in container B.

Explanation:

From the question,

Container A contains 1000 atoms

Container B contains 500 atoms

<u>The rate of decay of atoms in container A is greater than the rate of decay of atoms in container B.</u>

The reason for such is due to the difference in the concentration of the isotopes. Container A which contains higher number of atoms will have the more changes of the release of the neutron as the changes of the hitting and splitting increases as the density of the atoms increases.

<u>Thus, the atoms in the container A will therefore decay faster than the atoms in the container B. </u>
