<u>Answer:</u> The reaction is known as synthesis reaction.

<u>Explanation:</u>

Synthesis reaction is defined as the chemical reaction in which substances react in their elemental state to produce a single compound.

For Example: The formation of magnesium oxide from magnesium and oxygen gas.

$2Mg(s)+O_2(g)\rightarrow 2MgO(s)$

By Stoichiometry of the reaction:

2 moles of magnesium atom reacts with oxygen gas to produce 2 moles of magnesium oxide.

Hence, the reaction is known as synthesis reaction.

How does fingerprinting work with remote sensing and dna barcodes

Ede4ka [16]

Fingerprint is the print of our finger, remote sensing are placed usually in locks in safety areas, it identifies the matching fingerprint and allows the people to enter, and in DNA barcode, location can be detected by remote sensing.

<h3>What is remote sensing?</h3>

Remote sensing is the identification of the sense of people, the data is feed to the device then according to the data it senses the presence and allow that people.

DNA barcoding is taking small fragment of DNA to find the progeny or its availability.

Thus, Remote sensing is typically used in locks in security areas to identify matching fingerprints and allow people to enter, and in DNA barcodes, location can be detected using remote sensing.

First, let's start off by finding the mass of this whole hydrate.
(Note: the unit of measurement for mass will be amu)

Let's find the molecular mass of each element.
$Co=58.933$
$Cl=35.45$
$H=1.008$
$O=15.999$

Now, let's find the mass of each compound.

$CoCl_2=58.933+2(35.45)=129.833$
$H_2O=2(1.008)+15.999=18.015$

We have 6 molecules of H2O, so multiply 18.015 by 6 then add that with the weight of CoCl2.

$6(18.015)=108.09$
$129.833+108.09=237.923$

Now divide 108.09 (mass of all the H2O in the hydrate) by 237.923 (total mass of hydrate).

$\dfrac{108.09}{237.923}$

$\approx0.45431$

Turn that into a percentage and you get 45.431%.
Hope this helps! :)

Deuterium is the isotope of hydrogen of mass number 2, with a proton and a neutron in its nucleus. The chemistry of deuterium is

s344n2d4d5 [400]

Answer:

True

Explanation:

We know that the zero-point-energy of a C-D system is quite lower than the zero point energy of the C-H bond so the C-D bond is stronger.

Kinetic isotope effect refers to the change in the rate of reaction owing to a change of one of the atoms of the reactants by replacing it with one of its isotopes.

Since we know that the C-D bond is stronger than the C-H bond, when we replace hydrogen with deuterium in a reaction's rate determining step we experience a little lag in the rate of reaction. This is referred to as the kinetic isotope effect in physical organic chemistry.
