Olivine
Quartz typically forms last in Bowen's reaction series due to its high resistance to weathering and its stability under low-temperature conditions. As magma cools and crystallizes, quartz is one of the minerals that will precipitate out towards the end of the crystallization process.
Galena, which is a mineral containing lead sulfide, tends to stick to grease during separation from ore due to its natural hydrophobic properties. The grease selectively adheres to the galena particles, allowing them to be separated from the rest of the ore during processing.
Newton's First Law is called his First Law of Motion. It states that an object in motion tends to stay in motion unless influenced by something else that slows or stops its motion. Likewise, an object at rest - not moving - tends to stay at rest unless influenced by something else that starts it moving.
The streak is a more reliable way to identify a mineral than color because it reveals the true color of the mineral in its powdered form, which is less affected by external factors like impurities or weathering. Many minerals can appear similar in color due to these variations, but their streak color tends to be consistent. This characteristic provides a more accurate and consistent identification method, making it a preferred technique in mineralogy.
No, Newton's First Law of motion states that an object at rest tends to stay at rest and an object in motion tends to stay in motion with a constant velocity unless acted upon by an external force. There is no mention of the force being equal to the propelling force.
Bowens' Reaction Series measures the melting points of various silicate minerals, with the ones with highest melting points at the top. So as a completely moltenmagma containing all these minerals cools down, the first to crystallise are:ABOUT 1400 CELSIUSOlivinePyroxene (e.g. augite)Amphibole (e.g. hornblende)Biotite micaOrthoclase feldsparMuscovite micaSilica (e.g. quartz).ABOUT 800 CELSIUSNotice I've deliberately left out plagioclase feldspar because plagioclases of different composition crystallise out at different temperatures. Calcium-rich plagioclase crystallises out at about the same temperature as olivine (mineral 1), but sodium-rich plagioclase crystallises out about the same temperature as biotite mica (mineral 4). All plagioclase crystallises out at a higher temperature than orthoclase (mineral 5).So in answer to your question the first minerals to form as a magma cools are olivine and calcium-rich plagioclase feldspar, at around 1400 Celsius.
No. If x tends to infinite, 1/x tends to zero.
I think that is A Series of Unfortunate Events, which book in that series is hard to say, most likely the first one because that tends to be the one people read first and decide if they wish to read on.

fracture
Visually oil sheen tends to have a rainbow of colors and the sheen edges tend to be smooth and gracefully curved. Mineral sheen tends to be silver in color with jagged edges and fractures running through the sheen. As oil sheen ages and the oils degrade it becomes more and more difficult to differentiate between oil and mineral sheens because the oils tend to take on the appearance of mineral sheen.
An arithmetic series is the sequence of partial sums of an arithmetic sequence. That is, if A = {a, a+d, a+2d, ..., a+(n-1)d, ... } then the terms of the arithmetic series, S(n), are the sums of the first n terms and S(n) = n/2*[2a + (n-1)d]. Arithmetic series can never converge.A geometric series is the sequence of partial sums of a geometric sequence. That is, if G = {a, ar, ar^2, ..., ar^(n-1), ... } then the terms of the geometric series, T(n), are the sums of the first n terms and T(n) = a*(1 - r^n)/(1 - r). If |r| < 1 then T(n) tends to 1/(1 - r) as n tends to infinity.
Quartz is the last stop on Bowen's reaction series and represents a very very stable mineral which does not weather chemically so it tends to be over represented in the crust, beaches, sandstone, quartzite etc.
Foliation, or the alignment of mineral grains in a preferred direction, tends to increase as rocks experience metamorphism. This results in a layered appearance in metamorphic rocks, such as schist and gneiss.
This series of random letters tends to denote boredom, awkwardness, or lack of something to say on the Internet.

No. The mantle tends to be soft and ductile due to extreme heat. The mantle is constantly melting and mixing with itself, while the description of a mineral states: A mineral is a naturally occurring solid with a highly ordered atomic arrangement and a definite (but not fixed) chemical composition. It is usually formed by inorganic processes.
