Answer:

C. A Roman numeral placed after the transition metal identifies its

oxidation state.

Explanation:

A. A superscript on the transition metal identifies its oxidation state

in the formula.

This is wrong! Superscript are usually not written in formula of compound and for those that have superscripts, it refers to the oxidation number of the compound as a whole.

B. The subscript of the transition metal in the formula identifies its

oxidation state.

This is wrong! Subscripts shows how many atoms of the element is present.

C. A Roman numeral placed after the transition metal identifies its

oxidation state.

This is correct! Examples include; manganese (II) oxide, Potassium manganate (VII) etc

D. The total charge of the negative ion identifies the oxidation state

of the transition metal.

This is wrong! Because there are cases of other metals or cations being present in the compound aside the transition metal

Molodets [167]

Answer:

35.578g or 36g if you round

Explanation:

Q=mc ∆∅ where ∅ is temperature difference

1160= m x 1.716 x (42-23)

m = 1160/ 1.716 x19

m=35.578g

m = 36g to nearest whole number

Will the reaction of addition to an inhibitor be fast or slow?
ad-work [718]

Answer:hope we can be friends

can i please get brainliest

Although phlorizin inhibition of Na+-glucose cotransport occurs within a few seconds, 3H-phlorizin binding to the sodium-coupled glucose transport protein(s) requires several minutes to reach equilibrium (the fast-acting slow-binding paradigm). Using kinetic models of arbitrary dimension that can be reduced to a two-state diagram according to Cha’s formalism, we show that three basic mechanisms of inhibitor binding can be identified whereby the inhibitor binding step either (A) represents, (B) precedes, or (C) follows the rate-limiting step in a binding reaction. We demonstrate that each of mechanisms A–C is associated with a set of unique kinetic properties, and that the time scale over which one may expect to observe mechanism C is conditioned by the turnover number of the catalytic cycle. In contrast, mechanisms A and B may be relevant to either fast-acting or slow-binding inhibitors.

Why are redox reactions used in batteries?
Phoenix [80]

Answer:

Why are redox reactions used in batteries? The attraction between charged ions releases energy. The movement of electrons creates an electric current. The reactions are extremely exothermic, producing an electric current.

Explanation:

Why are redox reactions used in batteries?

The attraction between charged ions releases energy.

The movement of electrons creates an electric current.

The reactions are extremely exothermic, producing an electric current.

The reactions are extremely endothermic, inducing the movement of electrons.
