Answer: 2.8 moles
Explanation:
The balanced equation below shows that 1 mole of sodium oxide reacts with 1 mole of water to form 2 moles of sodium hydroxide respectively.
Na2O + H2O --> 2NaOH
1 mole of H2O = 2 moles of NaOH
Let Z moles of H2O = 5.6 mole of NaOH
To get the value of Z, cross multiply
5.6 moles x 1 mole= Z x 2 moles
5.6 = 2Z
Divide both sides by 2
5.6/2 = 2Z/2
2.8 = Z
Thus, 2.8moles of H2O are needed to produce 5.6 mol of NaOH
Covalent bonds can be classified as nonpolar and polar covalent given the electronegativity difference between two atoms (ΔEN).
Nonpolar covalent bond electrons are shared equally between two atoms, polar covalent bond electrons are shared unequally, atoms have partial charges, ionic bond electrons are completely transferred to one atom, full charges present. Therefore, the greater the electronegativity difference, the greater the bond polarity. Let's determine the types of bonds present in the compounds and arrange the ones with polar covalent in order of increasing ΔEN. Sulfur and oxygen are both nonmetals so the substance is covalent. Sulfur has EN = 2.5 and oxygen has EN = 3.5. Since there is an electronegativity difference, the S−O bonds in the substance can be classified as polar covalent bonds.

Answer:
A. 3-chloro-1-methylcyclobutane.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to infer that the name of this compound is A. 3-chloro-1-methylcyclobutane because of the fact that the parent chain is a cyclobutane which starts by the methyl radical as it has the priority over the chlorine radical which is actually named first at the third carbon (clockwise).
Therefore the name is given in A, accordingly to the IUPAC rules of nomenclature.
Regards!
Ethylene oxide is sporicidal. Option A is correct option.
<h3>What is ethylene oxide? </h3>
Ethylene oxide is defined as the cyclic ether or the simplest epoxide compound. It contains a ring structure consist of two carbon atoms and one oxygen atom. It is a colourless gas having fruity odour. Ethylene oxide is highly flammable and reactive and hence exposure which may result in lung injury or in respiratory irritation.
<h3 /><h3>Why ethylene oxide is sporicidal? </h3>
Ethylene oxide is a potent sterilant which can kill all life forms and having high sporicidal activity due to its property of high penetrating effects. It is also convenient to use and also effective at room temperature. Therefore, it is mostly used in hospitals to sterilize surgical equipment, instruments, and in disposable medical devices which are sensitive to heat and moisture.
Thus we concluded that ethylene oxide is sporicidal due to its property of high penetrating effects. Therefore, option A is correct option.
