The substance that is made up of only one type of atom is an ELEMENT.

Further Explanation

Matter can be classified into two major groups: pure substances and mixtures.

Pure substances are substances that have a uniform and definite composition. If one were to take a sample of any pure substance, the particles that make up the substance will all be the same and will have similar properties.

Mixtures are made up of two or more substances that are placed in a similar “container”. Their composition is not uniform so a sample of a mixture may have variable amounts of its components. The substances are only physically combined so they keep their original properties and they may be separated by simple means.  

Mixtures may be homogeneous or heterogeneous.

  • Homogeneous mixtures or solutions are mixtures wherein the components are evenly mixed and distributed so that it appears that they all exist in one phase. The individual components cannot be distinguished. Example, a mixture of salt and water is homogeneous because upon looking at it, it seems like salt and water exist in the liquid state because the salt particles are so small and evenly dispersed in the water that it is invisible.
  • Heterogeneous mixtures are mixtures wherein the components are distinguishable. An example of a heterogeneous mixture is sand and water. It is very clear to see the sand particles and the liquid water.  

Elements and compounds are examples of pure substances.

  • All atoms of the same element have the same number of protons. Elements cannot be broken down further into simpler substances by simple means.
  • Compounds are chemical combinations of two or more elements. Their properties are different from the properties of the elements that make up the compound. Compounds have a definite composition and cannot be broken down into their component elements by ordinary means.

Element is a pure substance that is <span>made up of only one type of atom.

An element cannot be broken down by any chemical means. However, nuclear reactions can lead to the generation of new elements.
Examples of elements include: copper, neon and iron.
Currently, there are 115 known elements in nature.</span>

Write a net ionic equation to show that acetylsalicylic acid (aspirin), hc9h7o4, behaves as a brønsted-lowry acid in water.
Thepotemich [5.8K]
By definition, Bronsted-Lowry acid is a proton donor in the acid-base neutralization reaction. When a weak acid like acetylsalicylic acid is reacted with water, the water here acts as the Bronsted-Lowry base. This is possible because water has properties of amphoterism - can act as an acid or base. In this case, acetylsalicylic acid would have to donate its H+ atom to water, so that it would yield a hydronium ion, H₃O⁺. The complete net ionic reaction is shown in the picture.

So, in the reaction, the products yield are the acetylsalicylate ion and the hydronium ion.

Which of the following will produce a precipitate?
nekit [7.7K]

Reaction of option c produces precipitate.

Rhodium on reacting with potassium phosphate produces rhodium phosphate which remain in solution due to low lattice energy for rhodium phosphate.

Niobium on reacting with lithium carbonate produces niobium carbonate and it will remain in aqueous form.  

Cobalt on reacting with zinc nitrate produces cobalt nitrate. This, Co(NO3 )2 is insoluble precipitate and settles at bottom whereas zinc ion will remain in solution as follows:

Co^2^+ + Zn(NO¬_3 )¬_2    Co(NO¬_3 )¬_2    + Zn^2^+

Potassium ion on reacting with sodium sulfide produces potassium sulfide which remain in solution

How many grams of water are made from the reaction of 4.0 grams of hydrogen gas with the given reaction 2H2+O2---&gt;2H2O
Sergeeva-Olga [200]

Answer:

The mass of water is 36 g.

Explanation:

Mass of hydrogen = 4 g

Mass of water = ?

Solution:

First of all we will write the balance chemical equation:

2H₂ + O₂  →  2H₂O

Number of moles of hydrogen = mass / molar mass

Number of moles of hydrogen = 4 g/ 2 g/mol

Number of moles of hydrogen = 2 mol

Now we compare the moles of water with hydrogen from balance chemical equation.

                               H₂     :     H₂O

                                2      :       2

Mass of water = moles × molar mass

Mass of water =  2 mol × 18 g/mol

Mass of water =  36 g

If the water oxygen is in excess than mass of water would be 36 g.

A 4.24 kg marble slab has the volume of 1564 cm3 What is the density in g/cm3
miskamm [114]

Answer:

The answer is

<h2>2.71 g/cm³</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

volume of marble = 1564 cm³

1 kg = 1000 g

4.24 kg = 4240 g

mass = 4240 g

The density is

density =  \frac{4240}{1564}   \\  = 2.710997442...

We have the final answer as

<h3>2.71 g/cm³</h3>

Hope this helps you
