A is your answer.  it cant be B because H doesn't equal 2 on both sides.it cant be C because S doesn't equal 3 on both sides of the equation . It also cant be D because Au doesn't equal 3 on the first part of the equation so your best answer is A. Hope this helps!!!!

Explanation:

A balanced equation is defined as the equation where number of atoms of the reactant equal to the number of atoms of the product.  

This also means that mass of the reactants is equal to the mass of products in a chemical equation.

For example, Au_{2}S_{3} + 3H_{2} \rightarrow 2Au + 3H_{2}S

Here, number of atoms on reactant side are as follows.

  • Au = 2
  • S = 3
  • H = 6

Number of atoms on product side are as follows.

  • Au = 2
  • S = 3
  • H = 6

Hence, the number of atom of reactant side are equal to the number of atoms on product side.

Therefore, the reaction equation Au_{2}S_{3} + 3H_{2} \rightarrow 2Au + 3H_{2}S is a balanced equation.

Using two or more sentences, describe how a light microscope creates a magnified image.
a_sh-v [17]

Answer:  A microscope is an instrument that produces a clear magnified image of an object viewed through it. A microscope must be able not only to magnify objects sufficiently but also to resolve, or separate, the fine details of the object that are of interest to the viewer. In the optical microscope visible light rays, reflected from or transmitted by the viewed object, pass through a series of lenses and form an enlarged image of the object. This image is produced at the normal distance of clearest vision, which is about 10 inches, or 25 centimetres, from the eye of the viewer.

Which three of the following entities are acellular?.
arsen [322]

Answer:

Prions archea, viroids bacteria, viruses protists are acellular while fungi is cellular.

While viruses have indeed been closely researched for more than a century for infections of people and animals, most viruses, particularly those that infect microorganisms, are still poorly understood. 

Pathogenic RNA molecules are known as viroids. Contagious protein particles are identified as prions. Viruses are larger than that of viroids. Viroids are larger than prions in size.

Molds, wild yeasts, as well as mushrooms are examples of fungi. Numerous fungi are multicellular and also have nuclei in their cells. A protein-encased DNA or RNA core defines viruses being non - cellular organisms. Some scientists disagree with the notion that viruses are living things.
