What is the equilibrium temperature if a 0.700 kg piece of copper at 273 degC is placed in a 0270 kg aluminum cup with 4.30 kg of water at the same initial temperature of 22.1 degC? Number Units Not the question you’re looking for? Post a...
For pure solids such as P(4)O(10) and P(4), the active mass (expressed through density) is constant at a given temperature. For mathematical convenience, it is taken as unity (1). Thus, K(eq)= (1)/([O(2)]^(5))
When the temperature of an exothermic reaction is increased, what happens to the equilibrium? A. Shifts to the right B. Shifts to the left C. No change D. Can't determine 相关知识点: 试题来源: 解析 B。解析:对于放热反应,升高温度,平衡向逆反应方向即向左移动。

The equilibrium constant is a characteristic of a specific chemical reaction at a specific temperature. It cannot be changed, but it can be affected by changes in temperature, pressure, or concentrations of reactants and products. The equilibrium constant can also be manipulated by altering the re...

But temperature comes about only when particles interact and achieve thermal equilibrium, Alexander explains. "To have a notion of temperature, you need to have a notion of interaction."EngberDanielPopular Science: The What's New Magazine
Another kind of equilibrium that we learned in chemistry is thermal equilibrium. This is what happens when we hold a piece of metal in our hand for some time, for example. The heat from hand will transfer to the metal and will change its temperature. The metal will become warmer and warme...
The brain is the control center of the body and regulates all systems to make sure we are alive and healthy. It is important for our bodies to maintain homeostasis, which means that we must keep internal conditions, such as body temperature, consistent....
