How many moles of Al2O3 are formed when .78 mol O2 reacts with aluminum? 0.52 mole How many moles of aluminum are in Al2O3? 1 moles How many grams are in 1 mole of aluminum? 26.982 g How many moles of oxygen are in aluminum oxide? The mole ratio is 32 , so 32×4.68=7.02 mol […]
How then does water move up the height of a 40 m tall tree?
How then does water move up the height of a 40 m tall tree? Water is move up the tree by using cohesion-tension, transpiration pull and the root pressure, technical they all happen at the same time; However, the cohesion-tension get it up to the 10m mark and the transpiration pull and the root pressure […]

How is energy transferred in a bicycle?
How is energy transferred in a bicycle? Mechanical energy usually means the sum of the kinetic energy and potential energy. So when you ride your bike you hope that the muscular (chemical) energy is converted mainly into mechanical energy. Unfortunately friction will produce heat and sound and will reduce the amount of mechanical energy that […]
Why do electrons lose or gain electrons?
Why do electrons lose or gain electrons? Explanation: Atoms and chemical species lose or gain electrons when they react in order to gain stability. Thus, typically, metals (with nearly empty outer shells) lose electrons to non-metals, thereby forming positive ions. The number of electrons depends on their position on the Periodic table (in simple terms). […]
How do RBC survive without nucleus?
How do RBC survive without nucleus? The red blood cells without nuclei, called reticulocytes, subsequently lose all other cellular organelles such as their mitochondria, Golgi apparatus and endoplasmic reticulum. The spleen acts as a reservoir of red blood cells, but this effect is somewhat limited in humans. Is RBC a living cell? rbcs are living […]
How does my body know how do you carry out the essential functions of life?
How does my body know how do you carry out the essential functions of life? Systems of specialized cells within organisms help them perform the essential functions of life, which involve chemical reactions that take place between different types of molecules, such as water, proteins, carbohydrates, lipids, and nucleic acids. All cells contain genetic information […]

Which are examples of water absorbing energy?
Which are examples of water absorbing energy? When water absorbs enough heat, it becomes a gas (water vapor). This process is called evaporation. Water vapor (steam) mixes with the air and seems to disappear. A simple example is water boiling in a teapot and escaping into the air. What happens when the kinetic energy of […]
Does conditioning affect emotion?
Does conditioning affect emotion? Does Conditioning affect emotions? Conditioning applies to visceral or emotional responses as well as simple reflexes. As a result, conditioned emotional responses (CERs) also occur. Behavior that occurs as an automatic response to some stimulus ; skinner’s term for behavior learned through classical conditioning. How is classical conditioning used today? Classical […]
