The elements that do not ordinarily form compounds are noble gases as they have complete octet.

What are elements?

An element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.

Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.

The number of protons in the nucleus is the defining property of an element and is related to the atomic number of the element.All atoms with same atomic number are atoms of same element.

A student measures the mass of a substance as 1.7132kg and it's volume as 0.65l. What is the density substance in g/mL? Round your answer to the correct number of significant figures

Answers

Answer:

The substance has a density of 2.636 grams per mililiter.

Explanation:

We must remember that density (\rho), measured in grams per mililiters, is the mass of the substance (m), measured in grams, divided by its volume (V), measured in mililiters. That is:

\rho = (m)/(V)

In addition, a kilogram equals 1000 grams and a liter equals 1000 mililiters. If we know that m = 1713.2\,g and V = 650\,mL, then:

\rho = (1713.2\,g)/(650\,mL)

\rho = 2.636\,(g)/(mL)

The substance has a density of 2.636 grams per mililiter.

The tendency of molecules to move toward areas of lower concentration is called _____.a. suffusion
b. diffusion
c. suspension
d. effusion

Answers

The correct answer is B. The tendency of molecules to move toward areas of lower concentration is called diffusion. This happens when there is a concentration gradient. This is described by the Fick's laws of diffusion. Diffusion is the net movement of molecules from a higher concentration to lower concentration to achieve equilibrium.

Answer:

B: diffusion

How many moles of H2O are produced when 64.0 g C2H2 burns in oxygen

Answers

The balanced chemical reaction will be: 

C2H2 + 5/2O2 = 2CO2 + H2O

We are given the amount of C2H2 being burned. This will be our starting point.

64.0 g C2H2 (1 mol C2H2 / 26.02 g C2H2) (1 mol H2O/1mol C2H2) ( 18.02 g H2O/1mol H2O) = 44.32 g H2O.

Thus, the answer is 44.32 g H2O.
