O B. oxygen
O
C. mercury
O D. aluminum
Aluminum is solid at room temperature and will, therefore, have a melting point that is above room temperature.
The room temperature is about 25 degrees Celsius.
Argon and oxygen are gases at room temperature.
Mercury is a liquid at room temperature.
Aluminum, on the other hand, is solid at room temperature. Hence, its melting point is definitely somewhere above room temperature.

to solve the amount of sulfuric acid to maximize the profitwe need to establish the profit
let S(x) = 100x the selling price
P = S(x) – C(x)
P = 100x – ( 100,000 + 50x + 0.0025x^2)
P = 50x – 100000 – 0.0025x^2
Getting the first derivative and equating it to 0
0 = 50 – 0.005x
X = 10000 units of sulfuric acid
But the capacity is only 7000 units
So 7000 units should be manufactured
c. gains three ions.
b. loses three electrons.
d. gains three electrons.
Iron rust is the oxidation process that affects iron. Iron reacting with oxygen loses three electrons to form rust. Thus, option b is accurate.
Oxidation is the redox process that raises the oxidationnumber by losing the electron of the species and the reduction will decrease the oxidation state by accepting the electrons.
The iron loses its three electrons when reacts with the atmospheric oxygen in rusting and gets oxidized. The metal oxide is produced as a result of the rust.
Therefore, option b. losing threeelectrons to produce rust is correct.

A: Scientists have not yet gotten a fusion reaction to happen on Earth.
B: Per gram of fuel, fission releases more energy than fusion.
C: The energy from fusion cannot yet be converted to electricity.
D: Fusion requires conditions that use too much energy to maintain.
According to the nuclear fission and nuclear fusion reactions,energy from fusion cannot yet be converted to electricity.
There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.
In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.
In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.
