Answer:
The answer is c( to send signals to control the body)
The 4 major characteristics of a mineral are: -It is formed by natural processes- not man made -It is inorganic- it's not alive, it never will be -It is a crystalline solid- a definite volume and shape with a repeating structure -It can be an element or compound with a definite chemical composition- made the same each time w/ and orderly arrangement of atoms Also, another answer might <span>be: -Texture -Hardness -Luster or shine -Color/streak Hope that helps</span>
Answer:
Explanation:
The easy way is knowing that all gases basically are 22.4 L/mol at SATP.
There fore 3.45 L/22.4 L/mol =0.154 mol
Or use PV=nRT
n=(1 atm)(3.45L)/(273 K)(0.82 L atm)/(mol K) =0.154 mol
same answer
Answer:
True statment
2) Styrofoam would make a good calorimeter
3) Insulating material would make a good calorimeter
Explanation:
The calorimeter is one which is insulated that is which will not absorb or let the heat to escape from it. the calorimeter is used to measure the heat change during a process so if it will allow to exchange heat with surrounding it will deviate the readings or observence.
Copper is a good conductor of heat so we cannot use it make a calorimeter.
Hence
1) Copper would make a good calorimeter : False
2) Styrofoam would make a good calorimeter: True
Styrofoam is a bad conductor or insulator so it can be and it is used for calorimeter.
3) Insulating material would make a good calorimeter
: True
4) A good calorimeter should easily absorb heat : false
