Answers
Answer:
52 mL of H₂O.
Explanation:
The balanced equation for the reaction is given below:
2H₂ + O₂ —> 2H₂O
From the balanced equation above,
2 mL of H₂ reacted with 1 mL of O₂ to produce 2 mL of H₂O.
Finally, we shall determine the volume of H₂O that will be produced by the reaction of 52 mL of H₂ at the same temperature and pressure.
This can be obtained as follow:
From the balanced equation above,
2 mL of H₂ reacted to produce 2 mL of H₂O.
Therefore, 52 mL of H₂ will also react to produce 52 mL of H₂O.
Thus, 52 mL of H₂O were obtained from the reaction.

note that aluminium and copper are elements,
copper II sulphate and aluminium sulphate are compound
The statement that best describes displacement reaction is an element and a compound react to form a different element and compound. The correct option is C.
What is displacement reaction?When a more reactionary element displaces, or continues to push out, a less reactive element from a compound containing the less reactive element, a displacement reaction occurs.
The less reactive element is now pure and uncombined following a displacement reaction.
A single-displacement reaction occurs when a more reactive element in a compound replaces a much less reactive element.
Metal displacement, hydrogen displacement, and halogen displacement are the three types of displacement reactions.
An element as well as a compound react to form a specific component and compound, according to the best description of displacement reaction.
Thus, the correct option is C.

A3+ and B2-
A3+ and B-
A+ and B-
A2+ and B-
Answers
Answer:
A3+ and B-
Explanation:
Elements in group 13 have outermost electron configuration, ns2np1 hence they form trivalent positive ions.
Elements in group 17 have outermost electron configuration ns2np5 hence they form univalent negative ions.
This implies that, if element A is in Group 13 and element B is in Group 17, the ions formed are A3+ and B-.

Fe2O3 (s) + CO (g) -> Fe(s) + CO2 (g) (unbalanced)
1.Calculate the number of grams of CO that can react with 0.150kg of Fe2O3
2. Calculate the number of grams of Fe and the number of grams of CO2 formed
when 0.150 kg of Fe2O3 reacts
Answers
Answer:
1. 78.9g of CO
2. 104.9g Fe and 124.0g CO2
Explanation:
Based on the balanced reaction:
Fe2O3 (s) + 3CO (g) -> 2Fe(s) + 3CO2 (g)
1 mole of Fe2O3 reacts with 3 moles of CO to produce 2 moles of Fe and 3 of CO2
1. The moles of 0.150kg = 150g of Fe2O3 -Molar mass: are:
150g * (1mol / 159.69g) = 0.9393 moles Fe2O3
Moles CO:
0.9393 moles Fe2O3 * (3mol CO / 1mol Fe2O3) = 2.818 moles CO
Mass CO -Molar mass: 28.01g/mol-:
2.818 moles CO * (28.01g/mol) = 78.9g of CO
2. The moles of Fe produced are:
0.9393 moles Fe2O3 * (2mol Fe / 1mol Fe2O3) = 1.8786 moles Fe
Mass Fe -Molar mass: 55.845g/mol-:
1.8786 moles Fe * (55.845g/mol) = 104.9g Fe
The moles of CO2 produced are:
0.9393 moles Fe2O3 * (3mol CO2 / 1mol Fe2O3) = 2.818moles CO2
Mass CO2 -Molar mass: 44.01g/mol-:
2.818moles CO2 * (44.01g/mol) = 124.0g CO2

A sample of oxygen gas has volume 150.0 mL, at 0.947 atm, what will be the volume of the gas at 750.12 mm of Hg if temperature remain constant.
Answers
Answer:
143.9 mL
Explanation:
Applying,
PV = P'V'................. Equation 1
Where P = Initial pressure, V = Initial Volume, P' = Final pressure, V' = Final volume.
Make V' The subject of equation 1
V' = PV/P'............. Equation 2
From the question,
Given: P = 0.947 atm, V = 150 mL, P' = 750.12 mm of Hg = (750.12/760) = 0.987 atm,
Substitute these values into equation 2
V' = (0.947×150)/0.987
V' = 143.9 mL

Write a balanced equation state the reaction type, and perform the requested stoichiometry: Carbon and hydrogen combine to form
methane. How many grams of carbon would be needed to react with 30.2 grams of hydrogen?
Answers
Answer:
C + 2H2 = CH4
Given 30.2g of H2
Find the Moles
Mole =Mass/Molar Mass
Molar Mass of H2 = 1x2 = 2g/mol
Mole = 30.2/2
= 15.1moles of Hydrogen gas.
Now from the balanced equation of Reaction above...
1mole of Carbon reacts completely with 2moles of Hydrogen gas.
"x" moles of carbon with react with 15.1moles of Hydrogen
x = 15.1/2
=7.55moles of carbon.
We now have moles of carbon.
To find mass
Mole =Mass/Molar Mass
Mass = Mole x Molar Mass
Molar mass of carbon = 12g/mol
Mass = 7.55 x 12
Mass = 90.6g of carbon is needed.

Explanation:
The carbon that does not undergo combustion is released as particles. This particles are called soot or dust. Incomplete combustion also leads to the production carbon monoxide.
What is combustion ?Combustion is an exothermic process in which a gas reacts with the atmospheric oxygen producing carbon dioxide and water. This reaction involves heat to the surroundings.
Sometimes the combustion does not occurs completely. When there is insufficient oxygen for the fuel to completely react with the air to form carbon dioxide and water leads to incomplete combustion. It also occurs when a heat sink, such a solid surface or flame trap, extinguishes the combustion.
One of the byproducts of incomplete combustion is carbon monoxide. The typical incomplete combustion process releases carbon, which results in the formation of soot and dust.

Explanation:
An ionic substance is formed between a positively charged cation and a negatively charged anion.
Ionic substances are generally formed from metal and nonmetal atoms with the metal atoms forming the cations and the nonmetal atoms forming the anions.
Among the given substances,
MgI2 is an ionic substance.
Since Mg is the metal atom. It forms a cation.
I is a nonmetal atom. It forms anion.
Hence,
MgI2 is an ionic substance.
Though AlCl3 looks like an ionic substance it is a covalent compound.
This is due to the high polarizability of [tex]Al^3+[/tex] ion.
The remaining two compounds do not contain any metal atoms.

A cup of coffee has 71 mL of coffee and 127 mL of water. What is the percent volume of the coffee solution?
Answers
Answer:
35.9%
Explanation:
The percent volume of the coffee solution can be calculated as follows:
% volume of coffee solution = volume of coffee/total volume of coffee solution × 100
According to this question, a cup of coffee has 71 mL of coffee and 127 mL of water. This means that, the total volume of coffee solution is;
71mL + 127mL = 198mL
% volume = 71/198 × 100
= 0.359 × 100
Percent volume of coffee solution = 35.9%
