Answer:

C. gamma ray

(Photo for proof at the bottom.)

Explanation:

A gamma ray is a type of radiation that occurs when an unstable nucleus emits a photon, the smallest unit of light. A photon has no mass or charge. Atomic and mass numbers are written based on the mass of the atom. But since no mass is lost when a photon is emitted, writing the emission of it isn't necessary.

Here's a photo of Edge, good luck.

Which group of extremophiles does thermus aquaticus belong to
Elan Coil [88]

Answer:

The correct answer is thermophiles.

Explanation:

Thermus aquaticus are heat resistant bacteria because these bacteria can survive under adverse environmental conditions like high temperature.

These bacteria belong to one of the most heat-loving groups of extremophiles that are thermophiles. Thermophiles are present in volcanic soil, geysers and around deep-sea vents where the temperature is extremely high.

Thermus aquaticus bacteria is used to manufacture an enzyme called Taq DNA polymerase, which is heat resistant and also an important factor in molecular biology.

hat is the percentage of water in the following compound? Answer using three significant figures. Sodium carbonate decahydrate,
BigorU [14]
You need to find the whole molar mass of the compound using the periodic table to add the values. 

Na2CO3= (2 x 23.0) + 12.0 + (3 x 16.0)= 106 g/mol
H2O= 10 x [ (2 x 1.01 ) + (16.0) ]= 180.2 g/mol

the total molar mass is 106 + 180.2 = 286.2 g/mol

the percentage of water you can find by doing "parts over the whole"

H2O%= 180.2 / 286.2 X 100= 63.0%

jarptica [38.1K]

<u>Answer:</u>

<em>Atomic number 75 is dedicated to an element named rhenium and has been given Re as its chemical name.</em>

<u>Explanation:</u>

With a really low concentration it is one of the rarest metals that is found in Earth's crust.

Like all other elements rhenium also has certain isotopes among with 185 and 187 are the most stable ones. Hence these two are the ones that are naturally available abundance is 34% and 63% respectively.
