The true statement is Most of the minerals in granite weather to clay except quartz.
So, the correct answer is A.
This is because quartz is a very hard and durable mineral that is resistant to weathering. Other minerals in granite, such as feldspar and mica, are more susceptible to weathering and break down into clay minerals over time.
This process is known as chemical weathering, where minerals are altered or dissolved by chemical reactions with water and other substances in the environment.
While some minerals may weather more quickly than others, the overall rate of weathering depends on a variety of factors such as climate, topography, and the composition of the rock.
Hence, the answer of the question is A.

add electron dots and charges as necessary to show the reaction of calcium and oxygen
The reaction between calcium and oxygen can be represented by the formation of calcium oxide (CaO), where calcium loses two electrons and oxygen gains two electrons to achieve stability.
Calcium has an atomic number of 20 and its electron configuration is 2, 8, 8, 2. Oxygen has an atomic number of 8 and its electron configuration is 2, 6. To achieve a stable electron configuration, calcium tends to lose two electrons, resulting in a 2+ charge (Ca2+). Oxygen tends to gain two electrons, resulting in a 2- charge (O2-). In the reaction between calcium and oxygen, each calcium atom will lose two electrons to form Ca2+ ions, and each oxygen atom will gain two electrons to form O2- ions. The resulting ions will combine to form calcium oxide (CaO), with the charges balancing out. The electron-dot structure can be represented as Ca(2+) + O(2-) → CaO.
