To solve this we assume
that the gas inside the balloon is an ideal gas. Then, we can use the ideal gas
equation which is expressed as PV = nRT. At a constant pressure and number of
moles of the gas the ratio T/V is equal to some constant. At another set of
condition of temperature, the constant is still the same. Calculations are as
follows:
T1 / V1 = T2 / V2
V2 = T2 x V1 / T1
V2 = 293.15 x 300 / 333.15
V2 = 263.98 cm^3
Talc is not a good choice when building a statue because the mineral Talc is one of the weakest minerals on the Mohs Scale with a hardness of 1 since it could be scratched by a fingernail, which means that when people build a statue with Talc, it could be easily broken down.
Answer:
You didnt give use the choices you have but I can try to help. Climate can change when it snows,rains,when it is sunny,or cloudy.
Explanation:
The rain allows the climate to cool down depending in the weather out. Same with cloudy weather. Snow can also cause temperature to drop down. When it is sunny, the climate in the sun will be warm, until getting in the shade and it gets cold again.
Answer:
Transition state falls apart to form products.
Explanation:
Reactants collide to form a transition state is actually the initial step (not the last step) because reactants have react with each other. Transition state is the middle stage, once this stage falls or passes, you get products. I have attached an example reaction scheme to better understand.
