Which is a weaker base, Cl or NO2

Chemistry

Natali [406]4 years ago

<span>To find out which of the bases is weaker the only thing you need is to compare the atomic number of each element you got from the task. Then, the smaller number is obviously indicates the weaker base. So from the periodic table we know that atomic number of Cl is 17, and atomic number of No2 is should be about 35 which is enough to conclude that Cl has a weaker base. </span>

Ipatiy [6.2K]

Answer:

Rows and columns.

Explanation:

Each atom gives up some of its electrons to create a kind of sea of these randomly moving charged particles. It's these free-flowing electrons that make metals conductive.

What is the average kinetic energy of 1 mole of a gas at 125 kelvin? (R = 8.314 J/K-mol)
Nookie1986 [14]
The average kinetic energy of a mole of gas can be determined through the equation KE= 1.5 nRT where R is the gas constant equal to <span>8.314 J/K-mol and T is temperature, The temperature for this problem is 125 Kelvin and n is equal to 1 mole. KE then is equal to 1558.88 Joules.</span>

Answer:

230
     Th
  90

Explanation:

The left side shows the element uranium with mass number 234 (superscript to the left of ths symbol) and atomic mass 92 (subscript to the left of the symbol).

So,  you have to find the mass number and atomic numbers missing on the right side which added to those shown for the helium atom reach 234 and 92.

This the the mathematics:

1) Mass number of U - mass number of He = 234 - 4 = 230 ⇒ the mass number of the missing element is 230.

2) atomic number of U - atomic number of He = 92 - 2 = 90 ⇒ the atomic number of the missing element is 90.

Now, you use the atomic mass to identify the element. You do it by simply searching in a periodic table. There you find that the atomic number 90 corresponds to thorium, whose symbol is Th.

Now you have that the product that completes the right side of the decay equation is:

230
     Th
  90

What are some examples of some monotonic ions found in the body and how do they affect the body? Please help, anything will help
Luba_88 [7]
Atoms are electrically neutral because the number of protons, which carry a 1+ charge, in the nucleus of an atom is equal to the number of electrons, which carry a 1- charge, in the atom. The result is that the total positive charge of the protons cancels out the total negative charge of the electrons so that the net charge of the atom is zero. Most atoms, however, can either gain or lose electrons; when they do so, the number of electrons becomes different from the number of protons in the nucleus. The resulting charged species is called an ion.
