Answer:
Chlorophyll is one. I can't quite remember other
Answer : The correct option is, (C)
Explanation :
A. 
This is synthesis reaction in which the two or more reactant react to give a single product.
B. 
This is combination reaction in which the two reactants combine to form a single product.
C. 
This is a neutralization reaction in which an acid react with a base to give a salt and water as a product.
D. 
This is a double displacement reaction in which the positive cation and negative anion of two reactants exchange their places to give two new products.
Hence, the reaction (C) is a neutralization reaction.
<u>Answer:</u> The enthalpy of the reaction is 269.4 kJ/mol
<u>Explanation:</u>
To calculate the heat absorbed by the calorimeter, we use the equation:
where,
q = heat absorbed
c = heat capacity of calorimeter = 675 J/°C
= change in temperature = 
Putting values in above equation, we get:
To calculate the heat absorbed by water, we use the equation:
where,
q = heat absorbed
m = mass of water = 925 g
c = heat capacity of water = 4.186 J/g°C
= change in temperature =
Putting values in above equation, we get:
Total heat absorbed = 
Total heat absorbed = ![[19993.5+114690.12]J=134683.62J=134.7kJ](https://tex.z-dn.net/?f=%5B19993.5%2B114690.12%5DJ%3D134683.62J%3D134.7kJ)
To calculate the enthalpy change of the reaction, we use the equation:
where,
q = amount of heat absorbed = 134.7 kJ
n = number of moles of hydrocarbon = 0.500 moles
= enthalpy change of the reaction
Putting values in above equation, we get:
Hence, the enthalpy of the reaction is 269.4 kJ/mol
We all struggle in some subjects, you do badly when you don't try, and sometimes we try and can't get the answer, I'll help with that. :)
The first answer is CO2(g), CO2 is a gas, and all gas have... 4) No definite shape, no definite volume.
A piece of ice, a block of wood, and a ceramic cup are solids. They have shapes that do not change and volumes that can be measured. Any matter that is a solid has a definite shape and a definite volume.
A liquid takes the shape of what holds it, besides a flat surface, which will just evidently, take the shape of a flat surface. A liquid has a definite volume, because the volume of a liquid is constant because forces of attraction keep the particles loosely together.
Gases attempt to fill a container of any shape or size. Therefore, it has no definite shape.
There are forces of attraction among the particles in all matter, therefore, it has no definite volume.
The second question might become easier with the explanation above. A liquid has a definite volume because the forces of attraction are loosely together! Therefore, it has a definite volume, but it will take the shape of it's container.
This means... Yes! 2) It retains its original volume but changes shape.
This one is easy. To convert one gram of a solid at its normal heating point to a liquid at the same temperature, is the 1) Heat of Vaporization.
Heat of Vaporization is the amount of heat energy required to convert one gram of a substance from a liquid to a gas.
The third question, the molecules for H20, in a solid phase are always in an geometric and arranged pattern.
Most solids are arranged in geometric and arranged patterns, and since H20 is not in its indefinitely shaped liquid phase, it has a definite shape and thus, retains a repeating (geometric) pattern.
(Note- Some solids like wax or rubber do not have an arranged or geometric pattern.)
The “average of a kinetic energy” is defined as the vitality of movement of particles of a framework.
Or in simpler terms, “energy motion”.
So when temperature increases, the average kinetic energy of a molecule(s) 1) increases.
