Answer:
See the answer below
Explanation:
A weak solution of acid would gradually dissolve the calcium carbonate in limestone statues. For example, dilute sulphuric acid formed from the dissolution of SO2 in rainwater would react with calcium carbonate according to the following equation;
<em>Generally, the rate of any reaction depends on a host of factors such as temperature, pressure, presence of catalysts, and surface area of reactants. The higher the surface area of reactants, the higher the rate of reaction.</em>
In this case, the rate of reaction of the dilute acid and the calcium carbonate depends on the surface area of the calcium carbonate which happens to be the only solid reactant. <u>Statues with intricate carvings seem to break down more quickly than ordinary statues because they offer more surface area for reaction to take place</u>. The intricate carvings create more surface area for reactions when compared to statues without intricate carvings.
Answer:
A: catalyst
Explanation:
In Chemistry, the rate of reaction of chemical elements (reactants) can be sped to produce a chemical compound or elements (products), through the addition of a catalyst that is unaffected by the reaction.
This ultimately implies that, to speed up a chemical reaction, add a catalyst that is unaffected by a reaction.
For example, an enzyme refers to a biological catalyst that is typically used to speed up (accelerate) the rate of a chemical reaction by lowering the activation energy of its reactants.
An enzyme can be defined as a biological catalyst that typically lowers the activation energy of a biological reaction. When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.
Generally, an increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.
Answer:
As more discovers were made, Whittaker proposed classifying organisms into five Kingdoms
Answer:
+1.76 V
Explanation:
Ecell = Ecathode - Eanode
= -0.19 - (-1.95) = + 1.76 V
Answer:
Higher molar mass compounds will be less soluble than lower molar mass molecules of the same type.
Explanation:
Bigger Mass = slower/less soluble
Small Mass = faster/more soluble
