Answer:

Buoyancy is the ability or tendency of an object to float in a fluid: a liquid or a gas. This happens because fluid pressure increases with depth. According to Archimedes' Principle, the buoyant force on a submerged object is equal to the weight of the liquid displaced by the object.

Henry Moseley used X-ray experiments to determine the atomic number of elements. How did his discovery contribute to the develop

sesenic [268]

Here we have to chose the correct statement which affect the discovery of the atomic number on the periodic table.

The discovery of the atomic number of the elements: C. It allowed the elements to be placed in strict order of increasing atomic number.

The use of X-ray determined the atomic number or number of electrons present in an element. The number of electrons is the basis of generate the periodic table, where the elements are arranged in terms of the number of electrons present in the atom in early stage of periodic table.

However in later the modern periodic table generated, which has group and period in terms of their property. Although the strictness on the increasing number of electrons are followed.

Please help me I'm really confused on how to do this. Can someone break it down for me? (stoichiometry)

bazaltina [42]

Answer:

so with every stoichiometry problem with a mass it will make it so you can do the conversion factor with reactants or products.

if you dont understand unit conversions try to study how to set it up. anyways

a.) C12H22O11 has a mass of 342.01 Grams per mole

divide 1.202 G by 342.01 G to get 0.004 miles

b.) you're just taking the AMU of each element in the chemical multiply it by how many there is of it in the chemical, then divide it by the mass of a mole of the chemical.

c.) you take your answers of part b and multiply them by Avogadro's number

What cycloalkanes are present in a steroid ?

11Alexandr11 [23.1K]

Steroids are biologically very important compounds. They are made up of more that seventeen carbons. The structure of Steroid is comprised of a fused cycloalkane ring system. The simplest steroid and the main skeleton of all steroids is Gonane.

Gonane is made up of four cycloalkane rings i.e. tetracyclic hydrocarbon ring structure. Among these four rings 3 are cyclohexanes (designated as A, B and C) and one is cyclopentane (Designated as D). These four rings fuse to form a <span>cyclopentaperhydrophenanthrene.

The Nucleus (Gonane) of steroids along with some derivatives are shown below,</span>
