3 0

No, x-rays do not travel slower than infrared radiation or even the opposite. Both are travelling in vacuum therefore they travel at same speed. They differ in the frequency of the electromagnetic waves.

Calculate the volume in liters of a 0.00231M copper(II) fluoride solution that contains 175.g of copper(II) fluoride CuF2. Be su

Free_Kalibri [48]

Answer:

Volume = 746 L

Explanation:

Given that:- Mass of copper(II) fluoride = 175 g

Molar mass of copper(II) fluoride = 101.543 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{175\ g}{101.543\ g/mol}$

$Moles_{copper(II)\ fluoride}= 1.7234\ mol$

Also,

Considering:

$Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}$

So,,

$Volume =\frac{Moles\ of\ solute}{Molarity}$

Given, Molarity = 0.00231 M

So,

$Volume =\frac{1.7234}{0.00231}\ L$

Volume = 746 L

Several general characteristics of metabolic reactions or reaction pathways are listed below. sort them into the appropriate met

Kobotan [32]

Answers are:
Catabolism:
- generally exergonic (spontaneous): In this reactions energy is released.
- convert NAD+ to NADH. Electrons and protons released in reactions are attached to NAD+.
- generation of ATP. ATP is synthesis from ADP.
- convert large compounds to smaller compounds. Foe example starch to monosaccaharides.
Anabolism:
- convert NADPH to NADP+. Protons and electrons are used to make chemical bonds.
- convert small compounds to larger compounds.

A mechanism for the decomposition of ozone is (2 O3 â†’ 3 O2). O3 â‡Œ O2 + OO + O3 â†’ O2 + O2What is the molecularity for the f

Gnesinka [82]

Answer:

The correct answer is option c.

Explanation:

Molecularity is defined as number of atoms , ions or molecules that must collide with one another so as to result in a chemical reaction.It is simply the sum of molecules of different reactants as represented in balanced chemical equation.

Reaction taking place in one step are said to be elementary reaction.

Reaction taking place in more than one step are said to be complex reaction.

A mechanism for the decomposition of ozone is given as:

1) $O_3 \rightarrow O_2 + O$

Molecularity for the first elementary reaction is 1. This because single ozone molecule is present.

2) $O + O3\rightarrow O_2 + O_2$

Molecularity for the second elementary reaction is 2. This because single ozone molecule reacts with 1 oxygen atom.
