Atomic Mass.
Reactivity decreases as you go down a group.
Atomic Radius also decreases as you go down a group.
Valence electrons are the same within a group.
Atomic mass, however, increases as you go down a group.
Hope this helps!
Answer:
Igneous rock to metamorphic rock
Metamorphic rock to igneous rock
Sedimentary rock to metamorphic rock
Explanation:
In changing a rock through the listed processes heat is highly required.
Transformation from a rock to igneous rocks requires the most heat because the rock body must be molten.
- Igneous rock to metamorphic rock is a metamorphic change that requires significant heat and pressure. The mineralogical fabric is affected by this change.
- In moving from metamorphic to igneous rock, the melting temperature of a rock must be attained in order for magma to form.
- Sedimentary changes to metamorphic rocks also require heat.
Answer: A is a decomposition reaction, and B is a synthesis reaction
Explanation: the first equation shows the reactant breaking up into 2 parts aka decomposition and equation 2 shows the reaction being combined into one part, aka synthesis. hope that helps!
Answer:
146
Explanation:
uranium is 92 and the mass number of the isotope is given as a 238 therefore it is not the two protons 92 electrons and

Answer:
To ensure provide and reliable data
Explanation:
Calibration ensures precise repeatable performance while preventing pipetting errors. Just the way measurement standards are established to distinguish valid and invalid processes, pipette calibration standards are designed to ensure the best pipette accuracy.
