Answer:
181 picometers is the radius of a gallium atom.
Explanation:
Primitive cubic cell is an arrangement in which constituent particles are present only at the corners of the cube.Also known as simple unit cell. In this arrangement number of total particles is equal to 1.
Gallium crystallizes in a primitive cubic unit cell.
Edge length of cubic unit cell = a = 362 pm
Let the radius be gallium atom be r
Two atoms of gallium touching each other = a =2r
362 pm = 2r
r = 181 pm
181 picometers is the radius of a gallium atom.
Hello! The reactions are catalyzed, or sped up by enzymes. Enzymes have strict conditions they can work under, including a small range of temperature. Temperature increase slows the rate of reaction, and extreme temperature increase can denature, or destroy an enzyme. Hope this helps! :)
Answer:
About 277 Kelvin
Explanation:
Take the celcius, and add 273.15 to it
4°C + 273.15 = <u>277.15K</u>
And round the answer to the nearest whole
277.15K ≈ 277K
The second one seems right
