They require diffrent types of atoms for their makeup I belive is the answer Hope this helps
Explanation: Wow you have a lot a questions XD :D :3
Answer: The pressure after the tire is heated to 17.3°C is 167 kPa
Explanation:
To calculate the final temperature of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
Putting values in above equation, we get:
Hence, the pressure after the tire is heated to 17.3°C is 167 kPa
Answer:
a.
b.
Explanation:
a. First, we solve the specific heat equation as follows:
b. Then, we use the molar mass of titanium to determine its molar heat capacity, as follows:
answer:
1) reaction is exothermic
2) some bonds are broken and some are formed (see explanation below)
Explanation:
When energy is written on the product side of a chemical reaction, means that the energy is appearing as consequence of the reaction, that is a released energy (heat) that heats the surroundings.
This kind of reaction where heat is released and, as a consequence, the temperature of the surroundings increase, is called exothermic.
In every chemical reaction some bonds are broken and others are formed.
Breaking bonds requires energy.
Forming bonds release energy.
The energy written on the chemical reaction is a net change of energy: the bonds broken on the reactant side used energy and bonds formed on the products side released energy.
When the energy released by the formation of the product is greater than the energy of the bonds broken on the reactant side, the chemical reaction is exothermic.
