Answer:
The atomic mass of this element would be 12 amu
Explanation:
The subatomic particles provide several bits of information about a given element.
The number of protons is equal to the atomic number of the element. For this element having 6 protons makes the atomic number 6 and makes the element Carbon.
The number of protons plus the number of neutrons equals the atomic mass of the element based upon atomic mass units (amus)
For this element 6 protons and 6 neutrons combine to make an atomic mass of 12 amus.
Lastly, the values of protons and electrons tell whether the atom is an ion or neutral. When protons equal electrons the atom is neutral. When protons are greater than neutrons the atom is a positive charge or cation. When the protons are less than the electrons the atom is a negative charge or anion. For this example the Carbon atom has 6 protons and 6 electrons making it neutral.
Answer: No, it cannot
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
Elementary reactions are reactions which takes place in single step. For elementary reactions the order is same as the stoichiometric coefficients.
Complex reactions are reactions that take place in more than one step and rate is determined by the slowest step of the reaction.
The given reaction is:
Rate law is: ![Rate=k[N_2O_5]^1](https://tex.z-dn.net/?f=Rate%3Dk%5BN_2O_5%5D%5E1)
As order is not same as the stoichiometric coefficient of 
, it is a complex reaction.
Number one is the balanced equation because both sides have 1 Ca 1 C and 3 Os
<span>Ideal Gas Law is as follows:
PV = nRT
Now lets rearrange so we can get rid of some variables.
V/n = RT/P
Assuming temperature and pressure are the same (atmospheric pressure), we can get:
PV/n = constant (k)
Now since we are dealing with an initial state (2.3 moles, 1.4 liters) lets set that as
V1 and n1 and the final state as V2 and n2
.V1/n1 = constant (k)
V2/n2 = constant (k)
Because the constant is the same (remember me making the assumptions above??)
V1/n1 = V2/n2
now rearrangement:
n1/V1/V2 = 1/n2 -1 = n2
Answer: 11.8 moles are in the final vessel. So to answer the question how much was ADDED, we need to subtract the initial mole number.
11.8 - 2.3 mols = 9.5 mols added</span>
You want a series circuit (a square)
You'll have your battery on the left side of the square
You'll have a switch on the top
