Answer:
A sliced loaf of bread will go stale quicker because more of the bread is revealed into the atmosphere where there are carbon and other elements in it which affect the surface area of the bread and the inner parts of the bread. It would take a shorter rate of reaction to get into the mid center of the bread than an unsliced loaf. Additionally, the dust and things in the air have to go through a tough surface of cells before it reaches the main part of the bread.
Explanation:
Answer:
Holmium
Explanation:
Electronic configuration:
[Xe] 6s² 4f⁵ 5d⁶
To know this element, we must first find the atomic number and then look for its position on the periodic table.
Number of electrons in [Xe] = 54;
So the total number of electrons = 54 + 2 + 5 + 6 = 67
This element has an atomic number of 57. On the periodic table, it is Holmium
Glucose is a simple sugar occurring both in plant and animal tissues. It has a chemical formula of (C6H12O6). Glucose is the byproduct of photosynthesis in plants and a raw material in the metabolism of animals. So, the answer to the above question is Glucose.
The correct response would be
A. Both, the types of atoms involved and or present in the chemical substance and the arrangements of such atoms within the compound can dictate the properties of the substance.
Explanation:
A property or characteristic of a substance that's determined throughout a reaction within which the chemical composition or identity of the substance is changed. Combustibility is a crucial property to think about once selecting building materials.
Answer:
chemical change
Explanation:
In chemical change , considerable amount of heat is used , hence a change in substance formed
