the reaction below shows how silver chloride can be synthesized. agno3 nacl nano3 agcl how many moles of silver chloride are produced from 15.0 mol of silver nitrate?

Answers

Answer 1
Answer: The balanced chemical reaction is:

AgNO3 + NaCl = AgCl + NaNO3

We are given the amount of silver nitrate to be used for the reaction. This will be the starting point of our calculations. 

15.0 mol AgNO3 ( 1 mol AgCl / 1 mol AgNO3 ) = 15.0 mol AgCl

0.5 grams of sodium chloride is dissolved to make 0.05 liters of solution. How do I solve this?

Answers

The concentration of the solution has been 0.17 M.

The molarity has been defined as the moles of solute that has been dissolved in a liter of solution. The molarity of the solution has been expressed as:

\rm Molarity=(Mass)/(Molar\;mass)\;*\;(1)/(Volume\;(L))

Computation for Molarity of the solution

The molar mass of sodium chloride solution has been 58.5 g/mol.

The given mass of NaCl in the solution has been 0.5 grams.

The volume of NaCl solution has been 0.05 L.

Substituting the values for molarity of the solution:

\rm Molarity=(0.5)/(58.5)\;*\;(1)/(0.05\;L)\n\nMolarity=0.17 M

The concentration of the solution has been 0.17 M. The solution has been prepared by dissolving 0.5 g NaCl in minimal water, and makeup the volume to 0.05 L.

If you are trying to find the molarity of this solution you first need to find the number of moles of sodium chloride that are present in the 0.5g sample.  To do this you need to divide the mass of sodium chloride (0.5g) by its molar mass (58.45g/mol) to get 0.00855mol of sodium chloride.  Then you divide the number of moles (0.00855mol) by the volume of solution (0.05L) to get 0.171M (The units for molarity is mol/L).  Therefore the solution has a concentration of 0.171M.

I hope this helps.  Let me know in the comments if anything was unclear or if you were asking a different question.

Which statement describes the composition of potassium chlorate, KClO3?(1) The proportion by mass of elements combined in potassium chlorate is fixed.
(2) The proportion by mass of elements combined in potassium chlorate varies.
(3) Potassium chlorate is composed of four elements.
(4) Potassium chlorate is composed of five elements.

Answers

Answer : The correct option is, (1) The proportion by mass of elements combined in potassium chlorate is fixed.

Explanation :

The composition of any compound is studied on the basis of law of fixed proportion. This law stats that in a compound the elements are present in fixed proportion by their mass.

In the given options, the option (1) statement describes the composition of potassium chlorate.

While the other options (2), (3) and (4) statements does not describe the composition of potassium chlorate.

Hence, the correct option is (1).

The statement that best describes the composition of potassium chlorate, KCIO3 is " The proportion by mass of elements combined in potassium chlorate is fixed."

How are elliptical galaxies different from spiral galaxies?a. They contain older stars and less gas and dust.
b. They contain younger stars and more gas and dust.
c. They are bigger than spiral galaxies.
d. They are smaller than spiral galaxies.

Answers

Answer:

A. They contain older stars and less gas and dust.

Explanation:

There are three types of galaxies:

  • elliptical galaxies
  • spiral galaxies
  • lenticular galaxies

Elliptical galaxies are galaxies shaped like an ellipse, while spiral galaxies consist of a flat, rotating disk that contains stars, gas, and dust, and a central concentration of stars called the bulge.

The difference between elliptical and spiral galaxies is in the amount of gas and dust they contain. Spiral galaxies contain large amounts of gas and dust, which means that new stars are born very often. This makes them brighter than relatively dim elliptical galaxies, which contain less gas and dust. This is why fewer new and brighter stars are born in elliptical galaxies, leaving them with older, dimmer stars.
