To be able to answer this, you need to have a phase diagram of Cu-Ni alloy. Create a vertical line along 40% in the x-axis. Then, create a horizontal line along the temperature at 1,300°C. The intersection lies outside of the α-L boundary.
<em>Therefore, the system consist solely of the L-phase: 100% L.</em>
Is it 8.06?
Or 58.57?
Don't get mad if there wrong!!
But please let me know if it's right or wrong tho.
Answer:
Explanation:
Aly's teacher said some bacteria can be as small as 0.00365 cm long.
In this problem, we need to write the length of the bacteria written in scientific notation. Any number can be written in the form of scientific notation as follows :
a is a real no and b is an integer
In the given number, there are two zeroes before 3. We need to shift the decimal after 3. It can be done as follows :
Hence, this is the required solution.
(3) both a chemical and a physical change can reach equilibrium. For example, an acid-base reaction can achieve equilibrium (chemical change), and a system can achieve dynamic equilibrium (phase changes from liquid to gas, for example), which is a physical change.
