It would be a gas because gases have the highest amount of kinetic energy and takes the shape/volume of it's container.
Hope this helps(;
The question is missing the table. Here is the complete question.
The tableshows the concentration of a reactant in the mixture over a period of time.
Reactant Concentration
Time (s) Concentration (M)
0 1.8
210 1.2
450 0.8
580 0.6
720 0.4
What is the average rate of reaction over the first 450 seconds?
A. 1.6x
M
B. 1.9x
M
C. 2.0x
M
D. 2.2x
M
Answer: D. 2.2x
M
Explanation: The average rate of a reaction is the rate of change of the concentrations (of reactants or products) in a period of time:
average = - ΔC/Δt
In this case, concentration is negative because it's related to reactant, since its concentration dimishes while the concentration of product increases.
For the first 450 seconds:
Average = 
Average = 
Average = 0.0022
or
Average = 2.2x
So, <u>the Average Rate of the reaction is 2.2x</u>
<u>M</u>
Answer:
- Deep red fire is about 600-800° Celsius
- Answer: {1102.91}
Given: K= °C + 273.15
K = 1,376.06
Since you’re trying to find C (Celsius) you want to get C by itself in the problem. So you subtract 273.15 from that side. Anything you do to one side of the equal sign you have to do to the other side, so also subtract 273.15 from K (1,376.06).
1,376.06 - 273.15 = {1102.91°C}
Answer:
neutron

neutrons have no net charge
Answer:
E
Explanation:
None of the above
The atom with the symbol S is called sulphur Sulphur has atomic number 16 which means that it has 16 protons. Sulphur-32 has 32 nucleons - 16 protons and 16 neutrons.Sulfur is a chemical element It is nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature.
