The answer is hydrogen bonding
To know how, first, we have to know that how much the molecules of the substance are moving relative to another one by measuring the temperature. when the temperature gets higher the more molecules are moving. all these moves of the molecules take energy.In our case, we are talking about the pure water H2O the reason that makes the more energy used to get the molecules of water moving and raising the temperature is that the molecules of water are sticking together tightly, As the water molecules are very polar. One side is negative charge O- and the other is a positive charge H+ (It's just like a magnet).So the attraction between the water molecules makes the movement of those molcules harder to move. So to break this attraction, we need more energy to raise the water temperature to change the water phase from solid (ice) to liquid phase.
Answer:
Explanation:
1. Increasing the concentrations of reactants in a chemical reaction would affect a reaction positively by increasing the number of collisions within a particular period which in turn increases the rate of reaction.
2. The molecules gains energy,which enable them to move faster and collide with the right energy for a reaction to take place.
3. The average kinetic motion of molecules in a solution can be measured by measuring the temperature. Temperature is a measure of the average kinetic energy of molecules in a solution.
The answer is helium 0.09 kg/m³.
The wave will move faster in the gas that is having lowest density.
As comparison to other gases-hydrogen, oxygen and radon; helium has the lowest density that is 0.09 kg/m³.
So, waves will move fastest in helium gas as it is having lowest density.
So the answer is helium gas that is waves will move fastest in helium gas.
When you focus on something
Answer:
Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements.
