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.

At a fixed pressure, if the temperature is doubled, the volume of a gas will be
Scrat [10]

Answer:

Doubled.

Explanation:

The relationship between the temperature and the volume of a gas at a constant pressure can be described using Charles' law:

  • V₁*T₂ = V₂*T₁

That means that the temperature and the volume of a gas are directly proportional: The higher the temperature, the higher the pressure. If one of those factors is increased twofold, the other one will be increased twofold as well.

How many atoms are in a sample of 72.8 g calcium (Ca)?
xxMikexx [17]
Atomic mass Ca = 40.078 a.m.u

40.078 g -------------------- 6.02x10²³ atoms
72.8 g ---------------------- ??

72.8 x ( 6.02x10²³) / 40.078 =

4.38x10²⁵ / 40.078 = 1.093x10²⁴ atoms

Determine the number of moles in 382.5g of CO-2
exis [7]

Answer: 8.691 mols of CO₂

Explanation:

To find the number of moles in a given grams, you want to use the molar mass.

Let's first find the molar mass of CO₂.

Carbon's molar mass is 12.011 g/mol

Oxygen's molar mass is 15.999 g/mol

To find molar mass of CO₂, we want to add up the molar mass of carbon and oxygen. Remember, there are 2 Oxygens so we need to mulitply that by 2.

12.011+2(15.999)=44.009 g/mol

Now that we have molar mass, we can convert 382.5 g to mols.

382.5g*\frac{1 mol}{44.009g} =8.691 mol

There are about 8.691 mols of CO₂.

What is the value for (delta)G at 1000 K if (delta)H = -220 kJ/mol and (delta)S = -0.05 kJ/(molK)?
tankabanditka [31]
The system is isothermal, so we use the formula:
(delta)G = (delta)H - T (delta) S

Plugging in the given values:
(delta)G = -220 kJ/ mol - (1000K) (-0.05 kJ/mol K)
(delta)G = -170 kJ/mol

If we take a basis of 1 mol, the answer is
D. -170 kJ
