C
I have had this question on a test before!! Hope this helps
a) figure describe ionization energy , electron affinity & electron negativity
b) figure describe Atomic Radius
c) does represent anything
Electronegativity : An atom attracted the bond pair of electrons in a covalent bond is called electronegativity of an element. H-->Cl
Ionization energy : The amount of energy is required to remove of an electron from an isolated gas atom is called Ionization energy. M + IP-----> M+ + e-
Electron affinity: The amount of enery is released when an electron added to an isolated atom is called electron affinity.
X + e- ------> X- =- EA
Atomic radius ; The distance between the center of neuclies and outer most shell is called atomic radius.
A chemical change is defined as something that changes the substance of something (such as the creation of water from hydrogen and water), and can be figured out if chemical or physical based on different changes and properties. Your answer will be D because these are two different elements (compounds in case of CO2) that combine to form a different substance, thus changing the identity of the substance.
Answer:
<h3>The answer is 8.98 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of cube = 150 g
volume = 16.7 cm³
We have
We have the final answer as
<h3>8.98 g/cm³</h3>
Hope this helps you
<span>C6H12O6 + O2 --> CO2 +H2O </span>
<span>In the balancede form we have: </span>
<span>C6H12O6 + 6O2 ---> 6CO2 + 6H2O </span>
<span>C -6 , H -12 and O - 18 </span>
<span>in both sides.</span>
