In the presence of dissolved oxygen, microorganisms can oxidize

nitrite ions (no–2) to nitrate ions (no–3) via the following reaction:

no−2 + 0.5 o2(aq) −−→ no−3

(a) this reaction is occurring in a batch bioreactor at a rate that is ﬁrst order with respect
to both no–2 and o2(aq), with k2=3×10^4 l/mol·d . how much time is required for the nitrite
concentration to be reduced from 0.3 mm to 0.1 mm if o2 is resupplied continuously to maintain
the o2(aq) concentration at 4mg/l?

Astudent made the lewis dot diagram of a compound as shown. mg is written with two dots shown on its top. an o is written on each side of mg. each o has six dots around it. an arrow is shown from one dot on mg toward the vacant space around the o on the right. another arrow is shown from the other dot on mg toward the vacant space around the o on the left. the title of the art is students lewis dot model. what is the error in the lewis dot diagram? an o atom should transfer all its six electrons to mg because the formula is mgo. both electrons of mg should be transferred to one o atom because the formula is mgo. the electrons should be transferred from each o atom to mg because mg has fewer electrons. the number of dots around mg should be four because it has to transfer two electrons to each o.

Question 1 how do an ionic bond and a covalent bond differ? an ionic bond is an attraction between oppositely charged ions. a covalent bond is a sharing of electrons between atoms. a covalent bond is an attraction between oppositely charged ions. an ionic bond is a sharing of electrons between atoms. there is no difference. both an ionic bond and a covalent bond share electrons. there is no difference. both an ionic bond and a covalent bond are attractions between oppositely charged ions. question 2 what is the definition of a covalent bond? a bond between two positive ions a bond between two negative ions a bond between a positive and a negative ion a bond between two atoms question 3 what is a bond called that shares electrons between two neutral atoms? covalent bond ionic bond metallic bond polar bond question 4 water (h2o) is composed of the same elements as carbon monoxide (co). how do their properties compare? they have different properties because the arrangement of atoms is different. they have the same properties because they have the same atoms. they have different properties because they have different atoms. they have the same properties because they have the same arrangement of atoms. question 5 what is the definition of a chemical bond? a mutual attraction between the nuclei and electrons in two different atoms a mutual attraction between the nuclei and electrons in a single atom a mutual repulsion between the nuclei and electrons in two different atoms a mutual repulsion between the nuclei and electrons in a single atom
