In metallic bonding, the electrons
Diano4ka-milaya [45]
A metallic bond is a bond between two metals or cations. In metallic bonding, the electrons are shared between the positive ions. The electrons move around between atoms. This is what allows objects with metallic bonds to be malleable and able to conduct electricity.

Identify two observations that a model of the universe would need to explain to be useful
juin [17]

"Theory relates to a model in science because it presents the possible paradigms and patterns of the said concept and fact. It explains and elaborates the phenomenon of why it happened, how it happened and the factors that are invovlved in the process. A theory is a possible explanation of certain occurence.

in addition, any time a scientific theory is challenged, it means it's not a good theory. And this statement is not valid. In theoretical models, they are revisited when there are further studies and discoveries found in a certain area where they can be remodeled and reintegrated instead of disregarding its credibility. Models, theories and paradigms are not challenged but rather encouraged, they are supported in many studies since these theories and models were created in order for us to understand a certain phenomenon but it would likely help the scientific society to be updated in the new forms or spheres of improvement rather than discouragement."

Which statements about the reaction are true? Select all that apply. The reaction is exothermic The reaction is endothermic The
Digiron [165]

The statements true for the reaction are A, C, and E.

The potential energy diagram of the following reaction has been given:

\rm CH_4\;+\;2\;O_2\;\rightarrow\;2\;H_2O\;+\;CO_2\;+\;891\;kJ

The reaction has been given to form water and carbon dioxide, along with the release of 891 kJ of energy.

<h3>Statements for the reaction</h3>

The endothermic reaction is  the type of reaction that absorbed the energy from the system, while exothermic reaction released energy in the system.

The given system has releasing 891 kJ of energy. Thus, it has been an exothermic reaction.

The equation has been representing the 891 kJ of energy as the product. Thus, it has been released in the reaction as product.

The potential energy graph has been representing that the energy of the reactant has been higher than the product.

Thus, the statements true for the reaction are A, C, and E.
