Answer:
See the explanation below, please.
Explanation:
The elements of the periodic table that belong to the same group (each column) have similar physical and chemical properties. This is because they have the same number of electrons in their last electronic layer.
Example of electronic configuration of elements of GROUP IA:
Hydrogen: 1s ^ 1
Lithium: 1s ^ 2 2s ^ 1
Answer: m= 6.2 g Ba
Explanation: Solution:
0.045 moles Ba x 137 g Ba / 1 mole Ba
= 6.2 g Ba
The answer to this question is the "C3", it is the complement protein cascade which is in the same way of the classical pathway, alternate pathway and especially the lectin pathway after the point in the cascade where the activation of the C3 takes place. The C3 in chemistry refers to the convertase and an enzyme with propylene its basic raw materials in the industries.
D the snapping back of a rock that has been strained by force
Explanation:
Elastic strain is the snapping back of a rock that has been strained by force. In elastic strain, the rock has not reached its yield point to become plastic.
- Elastic strain usually is due to action of stress that has not permanently caused deformation.
- After the stress is withdraw, the material returns back to its original state.
- We say the rock has not reached it's yield point.
- Beyond the yield point, the rock becomes plastic and does not return to its original position.
