Does silicon dioxide contain carbon?
Silicon dioxide contains only silicon and oxygen - no carbon., The only carbon in a sample labelled " silicon dioxide", would be an impurity or contaminant probably on the surface
What is the concentration of carbon dioxide in this sample?
well when the heart pumps then its the sample
Compute the density of an 820g sample of pure silicon occupying a 350 cm3 container?
2.34285714g/cm3
A 10g sample of the compound copper oxide contains 2.0 g of oxygenWhat mass of oxygen would a 30 g sample of the same compound contain?
it has 6 gram of copper
Does silicon get moldy when wet?
yes it gets very gren 2. I have a sample of silicon on my desk, and it is a grey colour with shiny conchoidal fracture. It has never resembled green. Perhaps you mean silicone (adhesive / sealant)?
What is a sample of SiO2?
silicon dioxide
In a sample of silicon dioxide the mass of oxygen is 60g. what is the mass of silicon present?
To determine the mass of silicon present in silicon dioxide, we need to consider the chemical formula, which is SiO2. This means that for every 1 mole of SiO2, there is 1 mole of silicon and 2 moles of oxygen. Since the molar mass of oxygen is 16 g/mol, the mass of oxygen in 60 g of SiO2 corresponds to 60/16 = 3.75 moles of oxygen. Therefore, the mass of silicon will be 28 g/mol (molar mass of silicon) * 1 = 28 g.

Would a sample of the compound carbon dioxide in your school and another sample of carbon dioxide in Australia have the same composition and properties?
Yes, a sample of carbon dioxide in your school and another sample in Australia would have the same composition since carbon dioxide is made up of one carbon atom and two oxygen atoms. They would exhibit similar properties such as being colorless, odorless, and non-flammable under normal conditions.
A sample that cannot be separated into two or more substances by physical means is what?
A sample that cannot be separated into two or more substances by physical means is a compound. A compound is made up of 2 or more elements which cannot be broken down by physical means.
How many atoms are in this compound Magnesium?
The question cannot be answered for several reasons. The first is that reduced magnesium is not a compound. Next, you did not provide either a weight or a volume of the sample of magnesium. Without either one or the other, one cannot calculate the number of atoms in the sample.
How many moles in 37.4g of SO2?
To determine the number of moles in 37.4g of SO2, we need to use the molar mass of SO2. The molar mass of SO2 is approximately 64.06 g/mol. By dividing the given mass by the molar mass, 37.4g ÷ 64.06 g/mol ≈ 0.58 moles of SO2.
What is the concentration of carbon dioxide in this sample?
well when the heart pumps then its the sample
Does fresh water have magnesium and silicon?
Unless it is "deionized water" fresh water will contain dissolved minerals. Both magnesium and silicon are likely to be in those dissolved minerals, but I cannot state with certainty if a given water sample contains them unless it has been chemically analyzed.
How many grams of silicon would there be in a sample that contained 9.99 x 1025 atoms?
The mass of silicon is 4 659 g.
What is the mass of a 350 cm3 sample of pure silicon with a density of?
2g/cm3
When a sample of germanium and silicon having same impurity density are kept at room temperature then resistivity of both?
The resistivity of germanium will decrease with increasing temperature due to a positive temperature coefficient of resistivity, while the resistivity of silicon will increase with increasing temperature due to a negative temperature coefficient of resistivity. At room temperature, silicon will have a higher resistivity compared to germanium.
