Answer:
insoluble simply means something that cannot be dissolved in water (:
Answer:
oxygen
Explanation:
The process in which a substance loses an electron in a chemical reaction is called oxidation. ... Oxidation is a combination of elements with oxygen. It's also a reaction of losing electrons and gaining positive charge. The atoms that lost electrons are said to be oxidized.
Answer:
N₂
Explanation:
Using ideal gas law, you can find moles of the gas:
PV = nRT
PV / RT = n
<em>Where P is pressure (2.00atm); V is volume (4.0L), n are moles of gas; R is gas constant (0.082atmL/molK); and T is absolute temperature (30.0°C +273.15 = 303.15K)</em>
Replacing:
2.00atm×4.0L / 0.082atmL/molK×303.15K = n
<em>0.322 moles of gas = n</em>
The difference in mass is equal to mass of the gas. Knowing both moles and mass of the gas, molecular mass of the gas is:
9.1g / 0.322mol = <em>28.3g/mol</em>
As the gass is a diatomic gas, each atom weights 28.3/ 2 = <em>14.1g/mol </em>and this is the mass of nitrogen atom. Thus, the diatomic gas is<em> N₂</em>
The correct answer is option B, that is, CO + H2O → H2 + CO2
The redox reactions are regarded as the chemical reactions in which one reactant goes through the process of reduction and one reactant goes through the process of oxidation. The reduction reactions are the reactions in which gain of electrons occurs, while oxidation reactions are the reactions in which loss of electrons occurs.
From the mentioned options, only option B, that is, CO + H2O → H2 + CO2 is a kind of redox reaction. In this, the carbon is getting oxidized from +2 to +4 oxidation state, and hydrogen is getting reduced from +1 to 0 oxidation state. Hence, this reaction can be regarded as a redox reaction.
