Answer: B.
The rate of the nuclear reaction increases, but the rate of the chemical reaction remains the same
Explanation:
How many grams N2O in 1 mol? The answer is 44.0128. We assume you are converting between grams N2O and mole. You can view more details on each measurement unit: molecular weight of N2O or mol This compound is also known as Nitrous Oxide.
We know that the element Z = 119 would be placed right below the Fr, in the column of the alcaline metals.
We also know that the trend in the electronegativity is to decrease when you go up-down ia group.
The known electronegativities of the elements of this group are:
Li: 0.98
Na: 0.93
K: 0.82
Rb: 0.82
Cs: 0.79
Fr: 0.70
Then the hypotetical element Z = 119 would probably have an electronegativity slightly below 0.70, for sure in the range 0.60 - 0.70.
The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element.
Answer:
The part of the experiment that is set to compare data
Explanation:
The controlled variable is what stays constant throughout an experiment. You use the controlled variable to compare the new data to see what happened during whatever reaction you could say.
