Answer:

No its is the oxidation half

Explanation:

Because Pb lost $2e^{-}$

and oxidation is losing, I abbreviate it in (OIL) not oil that used in kitchen

OIL=Oxidation Is Losing electrons

Answer:

Intensive

Explanation:

Intensive because it only depends on the type of matter and not the amount. Overall, I say intensive because it will not change when you change the amount of matter.

In the Haber process, nitrogen (N2) and hydrogen (H2) are directly combined to form ammonia (NH3). Which illustration contains t

Over [174]

The following illustration contains the stoichiometric quantities of the reactants for this reaction.

In the Haber process, nitrogen (N2) and hydrogen (H2) are directly combined to form ammonia (NH3). The reaction is as follows :

N $N_{2}$ + $3 H_{2}$ = $2NH_{3}$

Therefore, 1 mole of nitrogen is equivalent to 3 moles of Hydrogen

What is the perecentage yield of a reaction in which 200g PCl3 reacts with excess water to form 128g HCl according to the f.F re

castortr0y [4]

Answer:

The percentage yield is 80.36% (see calculations in attachment).

Explanation:

The theoretical yield of the reaction is the amount of product that would result if all the limiting reagent reacted. The theoretical yield is calculated using the balanced equation.

In practice, the actual yield, or the amount of product actually obtained from a reaction, is almost always less than the theoretical yield.

To determine how efficient this reaction is, we need to calculate the percent yield, which describes the proportion of the actual yield to the theoretical yield. It is calculated as follows:

$%yield = actual yield ÷ theoretical yield × 100%$

First we need to make sure that the equation is properly balanced. In the question they provide the balanced equation.

Since water is in excess, we calculate the theoretical yield using PCl₃.

Write the empirical formula of at least four binary ionic compounds that could be formed from the following ions:

KATRIN_1 [288]

Answer: $MgS$ , $MgBr_2$ , $V_2S_5$ and $VBr_5$ are four binary ionic compounds that could be formed.

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Mg is having an oxidation state of +2 called as $Mg^{2+}$ cation and $S^{2-}$ is an anion with oxidation state of -2. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral $MgS$ . Also $Mg^{2+}$ cation and $Br^{-}$ can combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral $MgBr_2$ .

Also Vanadium is having an oxidation state of +5 called as $V^{5+}$ cation and $S^{2-}$ is an anion with oxidation state of -2. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral $V_2S_5$ . Also $V^{5+}$ cation and $Br^{-}$ anion can combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral $VBr_5$ .
