Answer:
This list of electron configurations of elements contains all the elements in increasing order of atomic number.
To save room, the configurations are in noble gas shorthand. This means part of the electron configuration has been replaced with the element symbol of the noble gas symbol. Look up the electronic configuration of that noble gas and include that value before the rest of the configuration.

To calculate the amount of heat transferred when an amount of reactant is decomposed, we must look at the balanced reaction and its corresponding heat of reaction. In this case, we can see that 252.8 kJ of heat is transferred per 2 moles of CH3OH used. When 22 g of CH3OH is used, 86.9 kJ is absorbed.
Answer:
Chemical change is a chemical process that occurs when a substance combines with another to create an entirely new substance, this process is also called chemical synthesis
Explanation:
Answer:
B. Increase the mass of one of the objects.
E. Decrease the distance between the objects.
Explanation:
To effect an increase in the gravitational force between two objects, the mass of both objects should be increased and the distance between them reduced.
This is derived from the Newton's law of universal gravitation:
- It states that "the force of gravity between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them".
Therefore, if the mass of the two bodies are increased and the distance between them reduced, the gravitational force of attraction will increase.
