What's a word equation
Yuri [45]
A word equation is a chemical reaction described using words.
A common example is the act of photosynthesis - the process plants use to make glucose (sugar) to use as 'food'.
Plants convert water and carbon dioxide into oxygen and glucose.
A word equation to express this is:
Water + Carbon Dioxide → Glucose + Oxygen
The other type of equation is a symbol equation - this uses the symbols of the elements instead of the common names:
H₂O + CO₂ → C₆H₁₂O₆ + O₂
There is also a balanced version:
6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂
<em>If you want information on the balanced symbol equations, feel free to PM me.</em>

Can we cover the earth with one mole of pennies? Explain.
mezya [45]

Answer:

No we can’t cover the earth with one mole of pennies

Explanation:

We can’t cover the earth with one mole of pennies due to the fact that making this possible will require the flattening and extra expansion before it covers the whole surface.

The extra expansion and flattening with result in the loss of intermolecular forces and won’t remain as a solid and form other states of matter which won’t be able to cover the surface.

Carbon naturally occurs in two forms: diamond and graphite. Why do these two forms have very different properties?
Nookie1986 [14]
The differences in the properties of diamond and graphite is as a result of how their particles are arranged in space. This space arrangement leads to distinct crystal structures for the two compounds. In diamond, the carbon atoms are arranged in tetrahedral shape while in graphite the carbon atoms arrayed in planes.
 Hope this helps :)

To what volume should 5.0 g of KCl be diluted in order to prepare a 0.15 M solution? L
Nesterboy [21]

Answer:0.45L

Explanation:

molarity=0.15M

Mass=5g

No of moles=mass ➗ molecular mass

Molecular mass of KCL=39.0983x1+35.453x1

Molecular mass of KCL=74.5513

No of moles=5 ➗ 74.5513

No of moles=0.067

Volume in liters=No of moles ➗ molarity

Volume in liters=0.067 ➗ 0.15

Volume in liters=0.45L
