Answer:
From this I could observe the effect of concentration and surface area on the reaction rate. The concentrated acids can dissolve a large piece of limestone in a few days because the higher reactant concentration leads to more frequent collisions which increases the reaction rate. Acid rain is diluted with water which is why it can take decades. However, statues with intricate carvings break down more quickly because it increases the surface area which increases reaction rate.
Explanation:
What question are you talking about?
Density (p) is defined as the mass (m) per unit volume (v) or:
p = m/v
Using this relationship, the volume is:
v = m/p
Using the given values of mass of 80 grams and density of 8 g/cm3, the sample volume is:
v = 80 grams/8 grams/cm3
v = 10 cm3
The final answer is 10 cm3.
There’s no picture? regardless, if there are two numbers of electrons adding up to 8, then they will likely form an ionic bond/compound. if they can form a covalent bond with whatever amount of electrons, ex carbon 4 and 4, then it would b covalent compound
Answer:
No one is reduced.
Explanation:
It is an example oxidation reaction in which carbon is oxidised to form carbon dioxide.
