Carbon monoxide has _______of oxygen.
A. one Atom
B. zero Atom
C. two Atoms
Carbon monoxide has one Atom of oxygen.
Answer: Option A
Explanation:
Carbon monoxide (co) has one atom of carbon and one atom of oxygen. The characteristics of co gas are colorless, odorless and tasteless. Inhaling of carbon monoxide is dangerous because the oxygen in the presence of blood is displaced by it, which will make you become consciousness.
In the atmosphere of Earth, only a small amount of carbon monoxide is presented. Special design of ventilation systems can be installed in areas where a large group of people assemble to avoid the co gases.

Salt is a compound made from sodium (Na) and chlorine (Cl). Salt _____.
A. has properties very similar to sodium
B.has properties very similar to chlorine
C.has very different properties from sodium and chlorine
Answer:
The correct answer option is C. has very different properties from sodium and chlorine.
Explanation:
We know that salt (chemical name: Sodium Chloride) is made from two elements, Sodium (Na) and Chlorine (Cl). But the properties of the compound of sodium and chlorine has completely different properties than those of its elements: Sodium and Chlorine.
Sodium is quite a low density but highly reactive silvery white metal and Chlorine is a highly reactive greenish yellow gas. While salt (NaCl) is a crystalline material, white in color, which readily dissolves in water and is used as a condiment to add flavor to food.

Which method is used to extract minerals from stream bends and along coasts?
Extracting Surface Minerals. Surface mining is just what it sounds like - removing minerals that are near the earth's surface because this is where the ore deposits are located. ... When the ore is found in a wide area but it's not very deep in the ground, strip mining is used.
Answer:
i think its C: surface mining
Explanation:
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.
Do you think the United States should continue to execute criminals? Why or why not
I believe that it important for The US to continue to execute criminals. This is important because we don't want criminals to be running around shooting up people and causing trouble. We are already doing a good job dealing with criminals and putting them in prison aren't we? Why should we change? This is also a big part in polices jobs, so if we didn't continue to put criminals in jail, then how to police get payed, and how do we continue to get the security we need? Know even though this is a obvious question, on the other hand people could make a counter that it takes up too much space in prisons. Know this however is a reasonable argument, we have to punish criminals somehow correct? It's essentially grounding a six year old from not doing what he/she is told. The kid has to get punished somehow correct? Just like everyone in the world should be put in their place depending on whether it's murder or something less intense. That is just how the world is. We live and learn, but of course it is unacceptable to murder, hurt, or cause any abuse or harm to someone in any way.
Iron pyrite (FeS2) is the form in which much of the sulfur exists in coal. In the combustion of coal, oxygen reacts with iron pyrite to produce iron(III) oxide and sulfur dioxide, which is a major source of air pollution and a substantial contributor to acid rain. What mass of Fe2O3 is produced from 84 L of oxygen at 3.41 atm and 148◦C with an excess of iron pyrite? Answer in units of g.
4FeS₂ + 11O₂ = 2Fe₂O₃ + 8SO₂↑
n(FeS₂) = m(FeS₂)/M(FeS₂) = 6000/120 = 50 моль
по уравнению реакции - n(O₂) = (11*n(FeS₂))/4 = (11*50)/4 = 137,5 моль
V(O₂) = n(O₂)*Vm = 137,5*22,4 = 3080 л
ответ: V(O₂) = 3080 л

Answer:
[tex] 8.297 mol O_2 *\frac{2 mol Fe_2 O_3}{11 mol O_2} *\frac{159.69 gr Fe_2 O_2}{ 1mol Fe_2 O_3}= 240.90 gr Fe_2 O_3[/tex]
Explanation:
For this case we have the following equation:
[tex] 4FeS_2 +11 O_2 \rightarrow 2Fe_2 O_3 +8SO_2[/tex]
After balance the equation.
For this case we can use the following expression for an ideal gas:
[tex] PV = nRT [/tex]
And if we solve for [tex]n_{O_2}[/tex] we got:
[tex]n_{O_2} = \frac{PV}{RT} =\frac{3.41 atm *84L}{ 0.082 \frac{atm L}{mol K} (148+273)K} =8.297 mol O_2[/tex]
The mass for the [tex] Fe_2 O_3[/tex] is given by: [tex] 55.845gr*2 +16gr*3=159.69 gr[/tex], since we have 2 molecules of iron and 3 from oxygen.
For this case since the pyrite is the excess reactive we can calculate the amount of [tex]Fe_2 O_3[/tex] with the oxygen and we can do this:
[tex] 8.297 mol O_2 *\frac{2 mol Fe_2 O_3}{11 mol O_2} *\frac{159.69 gr Fe_2 O_2}{ 1mol Fe_2 O_3}= 240.90 gr Fe_2 O_3[/tex]
