What else can I help you with?
A student found thet her mixture was 15 percent NH4cl 20 percent NaCl and 75 percent Sio2 Assuming her caculations are correct what did she most likely do incorrectly in her experiment?
The student most likely mistakenly swapped the percentages of NaCl and SiO2 in her calculations. She likely misinterpreted the data or made an error in transposing the numbers during the calculations.
What of earths layers has the greatest amount of oxygen?
The Earth's crust has the greatest amount of oxygen. Oxygen makes up about 46.6% of the Earth's crust by weight, primarily in the form of oxides such as silicon dioxide (SiO2) and aluminum oxide (Al2O3).
Is silicon dioxide a mixture or pure substance?
Silicon dioxide is a pure substance. It is a chemical compound made up of silicon and oxygen atoms in a fixed ratio, with a specific chemical formula (SiO2).
Is quartz homo or hetero?
Pure quartz is a homomogeneous crystal.
A mixture was found to contain 1.05 g of SiO2 0.69 g of cellulose and 2.17 g of calcium carbonate what is the percentage of SiO2 in this mixture?
To find the percentage of SiO2 in the mixture, we first calculate the total mass of the mixture: 1.05 g (SiO2) + 0.69 g (cellulose) + 2.17 g (calcium carbonate) = 3.91 g. Then, we calculate the percentage of SiO2 in the mixture: (1.05 g / 3.91 g) x 100% = approximately 26.82% of SiO2 in the mixture.
Which substance would have the greatest ductility C(s) Fe(s) NaCl(s) SiO2(s) apex?
Among the substances listed, iron (Fe) would have the greatest ductility. Ductility refers to the ability of a material to deform under tensile stress, and metals like iron are known for their malleability and ductility. In contrast, compounds like NaCl (sodium chloride) and SiO2 (silicon dioxide) are brittle and do not exhibit significant ductility. Carbon in the form of graphite (C(s)) has some ductility, but it is generally less ductile than iron.
What substances would have the greatest ductility C(s) SiO2(s) Fe(s) or NaCl(s)?
Out of the substances listed, iron (Fe) would have the greatest ductility. Iron is a metal known for its high ductility property, meaning it can be drawn into thin wires without breaking. The other substances - carbon (C), silicon dioxide (SiO2), and sodium chloride (NaCl) - are not known for their high ductility.
What would have the greatest ductility?
Sio2
Is NaCl and SiO2 together a mixture or a compound?
NaCl and SiO2 together would be considered a mixture. A mixture is a physical combination of two or more substances that can be separated by physical means. In this case, NaCl (sodium chloride) and SiO2 (silicon dioxide) do not chemically combine to form a new substance, so they are still distinct substances within the mixture.
What substances would have the greatest ductility?
Materials like gold, silver, and copper exhibit high ductility due to their ability to deform under stress without breaking. These metals have metallic bonds that allow atoms to slide past each other easily under tension, resulting in significant ductility.
Are NaCl and SiO2 example of compounds or mixtures?
These two compounds form a mixture because they can not react with each other under normal conditions.
What are some common compounds?
h2otable salt (NaCl),table sugar ( C12 H22 O11) and sand (Sio2)
Is NaCl salt the second most common molecule on earth after H2O?
The most common molecule on earth is SiO2.
What would exhibit the greatest amount of covalent bonding lici ai2o3 of2and sio2?
Silicon dioxide (SiO2) would exhibit the greatest amount of covalent bonding among the compounds listed. This is because silicon (Si) and oxygen (O) have a higher electronegativity difference, leading to stronger covalent bonds. Al2O3 and OF2 also have some covalent bonding, but it is not as strong as in SiO2.
What contains a glasslike substance called silica?
silicon dioxide
Silver in quartz rock homogeneous or heterogeneous mixture?
Quartz is a homogeneous substance. It is the compound silicon dioxide, SiO2.
What minerals have the greatest chemical stability?
Minerals with a simple composition and strong bonding tend to have the greatest chemical stability. For example, minerals like quartz (SiO2) and diamond (C) have extremely stable chemical structures and are resistant to chemical weathering. Other stable minerals include halite (NaCl), calcite (CaCO3), and pyrite (FeS2).
