Hey there!
LEVELING FORCES WEATHERING AND EROSION ARE BOTH KNOWN AS LEVELING FORCES - WHICH MEANS THEY WEAR DOWN AND REMOVE ROCKS THAT ARE EXPOSED ON EARTH'S SURFACE.
WEATHERING IS THE BREAKUP OF ROCKS AT EARTH'S SURFACE DUE TO EXPOSURE TO THE ATMOSPHERE.
In particular, the two substances that do the most damage to rocks are:
<span>
OxygenWater</span>
The presence of just water and oxygen in the atmosphere is enough to break down all rocks given enough time.
EROSION IS THE REMOVAL AND TRANSPORTATION OF WEATHERED ROCK BY NATURAL AGENTS SUCH AS:
<span>
windglaciersriversrainwavescurrents</span>
WEATHERINGThere are many different processes that cause weathering, but all of them can be broken up into two main types:
<span>
Mechanical Weathering<span>
Chemical Weathering</span></span>
MECHANICAL WEATHERING
MECHANICAL WEATHERING (AKA PHYSICAL WEATHERING) OCCURS WHEN A ROCK BREAKS APART INTO SMALLER PIECES.
THIS IS A PHYSICAL CHANGE ONLY - THE PIECES ARE EXACTLY THE SAME AS THE WHOLE, JUST SMALLER
Hopes this helps u :D
1) Atomic number of magnesium (Mg) is 12, it means that it has 12 protons and 12 electrons.
Electron configuration of magnesium atom: ₁₂Mg 1s² 2s² 2p⁶ 3s².
2) Atomic number of aluminium (Al) is 13, it means that it has 13 protons and 13 electrons., but if it lost one electron, it will have 12 electrons and 13 protons and become aluminium cation Al⁺.
Electron configuration of aluminium cation: ₁₃Al⁺ 1s² 2s² 2p⁶ 3s².
3) Atomic number of silicon (Si) is 14, it means that it has 14 protons and 14 electrons., but if it lost two electrons, it will have 12 electrons and 14 protons and become silicon cation Si²⁺.
Electron configuration of silicon cation: ₁₄Si²⁺ 1s² 2s² 2p⁶ 3s².
The answer is 680L because once you balance the equation, there is 2 moles of hydrogen so you multiple the amount of hydrogen by 2.
