Question 2: Answer is (B), Soil Conservation Act (1936)
Hope that helps!!!
Isotopes are the atoms of the same element with same atomic number but different mass number isotopes of same element have same chemical properties due to same number of electrons atomic number of an atom is the number of electrons protons in it and mass number is the sum of protons
Answer:
3°F, 0°F, -11°F, -16°F, -20°F
Explanation:
The Fahrenheit scale is a temperature scale proposed in 1724 by the physicist Daniel Fahrenheit.
In this scale:
- The freezing point of water is set at 32 degrees
- The boiling point of water is set at 212 degrees
One degree in the Fahrenheit scale is indicated with the symbol 
.
The equivalence between temperature in Celsius degrees and Fahrenheit degrees is as follows:
to convert from Fahrenheit to Celsius
to convert from Celsius to Fahrenheit
The Fahrenheit scale is an increasing monotonic scale, it means that temperature goes from negative values towards positive values without interruption. Therefore, the temperatures listed from warmest to coldest are:
3°F, 0°F, -11°F, -16°F, -20°F
Niobium has Highest ionization energy.
<u>Explanation:</u>
The next ionization energy removes an electron from the same electron shell, which increases "ionization energy" due to "increased net charge"of the ion from which the electron is being removed.
Let's compare each of the metals first ionization energies,
Rubidium has its first ionization energy as 403 kJ / mol.
Zirconium has its first ionization energy as 660 KJ / mol.
Niobium has its first ionization energy as 664 KJ / mol.
From the given data above, we can infer that Rubidium has the least Ionization energy whereas Niobium has the highest Ionization energy. We can give the increasing order of the given elements as follows-
Rubidium < Zirconium < Niobium
Yes it’s correct your answer connect with eachother I did this before
