Using the method of initial rates for the reaction a → b, if the initial concentration of a is doubled and the rate of reaction

zmey [24]

Answer is: reaction is second order with respect to a.
This second order reaction is proportional to the square of the concentration of reactant a.
rate of reaction = k[a]².
k is second order rate constant and have unit M⁻¹·s⁻¹.
Integrated rate law for this reaction: 1/[a]=1/[a]₀ + kt.
t is time in seconds..

Glucose is a simple sugar made up of carbon, hydrogen, and oxygen. What kind of molecule is

Flauer [41]

The answer is C. Glucose is an organic molecule.

Glucose is carbohydrate so it cannot be a protein or a nucleic acid. It is an organic molecule. The organic molecule is compound consisting of carbon to which are attached hydrogen, oxygen, and nitrogen. Since, glucose is a simple sugar made up of carbon, hydrogen, and oxygen, it, as well as any other carbohydrate, is the organic molecule.

Use the table to calculate ΔH°rnx for the following reaction

alexdok [17]

Answer:

The answer to your question is ΔH° rxn = -1343.9 kJ/mol

Explanation:

P₄O₆ (s) + 2 O₂ (g) ⇒ P₄O₁₀

ΔH°rxn = ?

Formula

ΔH°rxn = ∑H° products - ∑H° reactants

H° P₄O₆ = -1640.1 kJ/mol

H° O₂ = 0 kJ/mol

H° P₄O₁₀ = -2984 kJ/mol

-Substitution

ΔH° rxn = (-2984) - (-1640.1) - (0)

-Simplification

ΔH° rxn = -2984 + 1640.1

ΔH° rxn = -1343.9 kJ/mol

Balance each reaction and write its reaction quotient, Qc:(b) POCl₃(g) ⇄ PCl₃(g) + O₂(g)

Komok [63]

When we balance the given equation

POCl₃(g) ⇄ PCl₃(g) + O₂(g)

We will get

2POCl₃(g) ⇄ 2PCl₃(g) + O₂(g)

Solution:

Balancing the given equation

POCl₃(g) ⇄ PCl₃(g) + O₂(g)

Balancing the number of O

2POCl₃(g) ⇄ PCl₃(g) + O₂(g)

Balancing the number of P and Cl

2POCl₃(g) ⇄ 2PCl₃(g) + O₂(g)

We get the balanced equation

2POCl₃(g) ⇄ 2PCl₃(g) + O₂(g)

The reaction quotient will be

Qc = [product] / [reactant]

Qc = [PCl₃(g) + O₂(g)] / [POCl₃(g) ]

For the reaction 2HNO3 + Mg(OH)2 → Mg(NO3) 2 + 2H2O, how many grams of magnesium nitrate are produced from 4 grams of nitric aci

kotegsom [21]

Answer:

First check to make sure you have a balanced equation

Second use mole ratios to set up what you need to know

Finally convert the moles to grams using the correct molecular weight

I will get you started

According to the reaction above, one mole of Magnesium Nitrate is produced from 2 moles of Nitric Acid

1 mole of Mg(NO3)2/2 moles of HNO3

5 grams of Nitric acid contains

5 g * 1 mole/63 g of Nitric Acid = 0.079365079 moles
