Answer: The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. Hope this is what your looking for.
Explanation:
False, carbon is an allotrope that can be in the forms of graphite, diamond etc
Answer:
Volume = mass/density
Rearrange the equation for Mass:
Mass = Volume x Density
That is one way you can do it
Conceptually, just look at the units, the wood block's density is 0.6<u>g/cm^3</u> while the volume is 2.2 <u>cm^3</u>
So if density is every gram per centimeter cubed, and the volume is at centimeter cubed, the logical thing to do would be to multiply the density by the volume to get the total mass.
0.6g/cm^3 x 2.2cm^3 = 1.32g
<u>Therefore the mass of the block of wood is 1.32g </u>
Explanation:
The substance that is in excess that doesn't get used up as a reactant is called limiting reactant.
Answer:
It increases when a catalyst is added.
Explanation:
The following factors control reaction rates:
1. Nature of reactants
2. Concentration of the reactants or pressure of gaseous
3. Temperature
4. Presence of catalyst
5. Sunlight
The addition of a foreign body to a reaction may influence the speed of the reaction. If a foreign body increases the rate of reaction, it is a called a positive catalyst or simply a catalyst. A negative catalyst is called an inhibitor.
A catalyst is a substance that is introduced into a chemical reaction to change the rate of the reaction without itself being affected at the end of the reaction.
Catalysts helps to reduce reaction time of many slow reactions. Most catalysts are specific in their actions and works on certain reactions or substrates.
Temperature change has a considerable effect on reaction rates since temperature is directly proportional to the average kinetic energy of reacting particles. Generally, reaction rate varies as temperature directly.
