Answer: The ratio of mass of sulfur atom to mass of oxygen atom in sulfur dioxide is 1: 1.
Explanation:
Law of constant proportion states that In a chemical substance the elements are always present in definite proportions by mass. This law is also known as 'Law of definite proportions '.
Mass of 1 atom of sulphur = 32 g
Mass of 1 atom of oxygen = 16 g
Mass of 2 atoms of oxygen =
In formation of , 1 atom of sulfur combines with 2 atoms of oxygen and thus the mass ratio will be 32: 32= 1:1 .
Thus the ratio of mass of sulfur atom to mass of oxygen atom in sulfur dioxide is 1: 1.
Answer:
Option D.
Explanation:
Some of the alpha particles Rutherford shot at the gold foil bounced back, some scattered; but the majority of them went right through. That meant there had to be some sort of positively charged subatomic particle in there that pulled them through, but it had to be at the center and couldn't take up a lot of room.
Number of hydrogen atoms in 0.98 mol of cisplatin is 0.98* 6.023*10^23 atoms.

What is cisplatin?</h3>
A number of malignancies are treated with the chemotherapeutic drug cisplatin. In this group are cancers of the testicles, ovaries, cervix, breast, bladder, head and neck, esophagus, lung, mesothelioma, brain tumors, and neuroblastoma. To administer it, a vein is injected.
The suppression of bone marrow, hearing issues, kidney damage, and vomiting are frequent adverse effects. Other severe side effects include heart disease, electrolyte imbalances, allergic responses, numbness, and difficulty walking. The growing fetus may suffer from use while pregnant. Cisplatin belongs to the class of drugs known as platinum-based antineoplastics. It functions in part by attaching to DNA and preventing replication.
