Answer:
There are three forces acting on the skateboard. One of these forces is the weight of the rider. Another is the force of gravity on the board itself. The third is the force of the ground pushing up on the skateboard.
Compounds have different conductivity because if they have the same meaning it wont be a other word. the compounds have to have a conductivity so there can be more meanings.
A.Because the Carbon dioxide in the air mixes it to form carbonic acid
You can determine an element based on its protons due to the atomic number.
Atomic number is the number of protons in an atom and you can locate it on your periodic table as the number above the letter. Each element has a different number of protons and because of that you can find the element on the periodic table based on its atomic number.
Following three <span>things when applied could make the reaction to occur more quickly;
1) Increasing Temperature:
Increase in temperature increases the Kinetic energy of molecules. This results in increase in the velocity and rate of collisions between reactants. Hence, greater the number of collisions between reactants per time greater will be the probability of formation of product per unit time.
2) Grinding Calcite:
Grinding of Calcium carbonate results in the increase of surface area of calcite. So greater the surface area greater is the exposure of Calcium carbonate to HCl molecules, hence the rate of formation of product increases.
3) Using Catalyst:
Very important. Catalyst when used decreases the activation energy and increase the rate of reaction by following methods.
a) Providing new pathway
b) weakening the bonds
c) providing surface area
d) holding up the reactant close to each other.</span>
