The reaction A → B + C is known to be zero order in A with a rate constant of 5.0 × 10–2 mol/L·s at 25°C. An experiment was run

DerKrebs [107]

Answer:

D. 2.5 × 10–4 M

Explanation:

Data given in the question are;

rate constant of 5.0 × 10–2 mol/L·s

[A]0 = 1.0 × 10–3 M

5 × 10–3 sec

It was mentioned that the reaction is a zero order reaction. One interesting charaacteristics about zero order reactio is that the rate of reaction is indepenedent on the concentrations of the reactants.

This means in zero order reactions, we have;

Rate = Rate constant

Rate = 5.0 × 10–2 mol/L·s

What is the concentration of B after 5 × 10–3 sec?

Concentration = Rate * Time

Concentration = 5.0 × 10–2 * 5 × 10–3

Concentration = 2.5 × 10–4 M

Correct option = D

Answer:

Explanation:

Mass is a measure of the amount of matter in a substance or an object. The basic SI unit for mass is the kilogram (kg), but smaller masses may be measured in grams (g). To measure mass, you would use a balance. ... In that case, the fruit would have a mass of 1 kg, the same as the iron.

xeze [42]

Answer:

Explanation:

Ratio of mass of C , N , H and O

= .8007 :0.9333:0.2016:2.133

Ratio of moles of C , N , H and O

= .8007/12 : .9333 / 14 : 0.2016 / 1 : 2.133/16

= .0667 : .0667: .2016 : .1333

= .0667 / .0667 : .0667 / .0667 : .2016 /.0667 : .1333 / .0667

= 1 : 1 : 3: 2

Hence empirical formula = CNH₃O₂

Weight of titanium Ti = 1.916 g

Weight of oxygen = 3.196 - 1.916 = 1.28 g

Ratio of weight of Ti and O

= 1.916 : 1.28

Ratio of moles of Ti and O

1.916/48 : 1.28/16 [ Molecular weight of Titanium is 48 ]

= .04 : .08

= .04/.04 : .08/.04

= 1 :2 .

Empirical formula

TiO₂
