How much heat must be absorbed by 50 grams?
Joule (J) is a unit of energy.Gram (g) is a unit for mass.
What is the amount that must be absorbed to start a reaction?
That is referred to as the activation energy.
What is the amount that must be absorbed to start the reaction called?
The amount that must be absorbed to start a reaction is called the activation energy. This energy barrier needs to be overcome for reactants to transform into products, allowing the reaction to proceed. It is essential in determining the rate of the reaction and varies for different chemical processes.
Why must an electron absorb a fixed amount of energy to jump from its ground state to an excited state?
An electron must absorb a fixed amount of energy to jump from its ground state to an excited state because energy levels in an atom are quantized. This means that electrons can only occupy specific energy levels, and the energy difference between these levels corresponds to a precise amount of energy that must be absorbed for the transition to occur. If the energy absorbed is not equal to this specific amount, the electron cannot transition to a higher energy state, resulting in no excitation.
What must energy do to break achemical bonds for a reaction to occur?
Energy must be absorbed to break chemical bonds for a reaction to occur. This energy input is needed to overcome the bond's stability and allow new bonds to form in the reaction.

The heat of fusion for water is the amount of energy that must be absorbed for water to what?
Melt.
When an electron gets excited is energy released or absorbed?
When an electron gets excited, energy is absorbed to move the electron to a higher energy level. This absorbed energy gets released when the electron returns to its original energy level, emitting electromagnetic radiation such as light.
How much heat energy must be absorbed to completely melt 35 grams of h2o at o degrees?
it will be 11,700J since the formula would be: q=mHf=35g x 334 J/g= 11,700 J
How does energy play a part in matter changing state?
Energy directly relates the the temperature of a substance. The more energy in is proportional to a higher temperature. The inverse is also true. When changing states you must use the formula Q=ML where Q is the energy in Jules, M is the mass in grams and L is the latent heat (fusion or vaporization) of the substance. This determines how much energy is needed to change state.
How much heat energy must be absorbed to completely melt 35.0 grams of water at 0 degrees Celsius?
The heat energy required to melt a substance can be calculated using the formula: heat energy = mass * heat of fusion. For water, the heat of fusion is 334 J/g. So for 35.0 grams of water, the heat energy required to completely melt it is 35.0 g * 334 J/g = 11,690 J.
What happens to electrons when pigments in photo-systems 2 absorb light?
Light or photons are little packets of energy. When this energy is absorbed by an electron it boots the electrons energy and the electron jumps to a higher orbital shell position (which must be vacant of its electron). The electron can only do this when the energy needed for the jump and the energy in the incoming photon match. Thus specific colours of light are absorbed depending on the element present.
What must be absorbed for a solid to melt?
They must gather close together until they can't bunch anymore and then they start to melt because they ran out of space.

How much must be added to 830 grams to make 1 kg?
To convert grams to kilograms, you divide by 1000 since 1 kg is equal to 1000 grams. Therefore, to find out how much must be added to 830 grams to make 1 kg, you subtract 830 grams from 1000 grams, which equals 170 grams. So, 170 grams must be added to 830 grams to make 1 kg.
