Which type of radioactive decay produces particles with the most mass? Alpha.
Answer is C.
Converting temperatures to degrees K: 33 degrees C = 306 K and -55 = 218 degrees K.
By the ideal gas law:-
760 * 0.50 / 306 = P * 0.10 / 218
P = 760 * 0.50 * 218 / 306 * 0.10
= 2700 mm Hg answer
<u>Answer:</u> The atom with 6 protons and 6 neutrons and an atom with 6 protons and 7 neutrons are the isotopes of same element.
<u>Explanation:</u>
Isotopes are defined as the chemical species that belong to the same element but differ in their mass number.
This also means that the chemical species have same number of protons and electrons but different number of neutrons.
Atomic number is defined as the number of protons or electrons that are present in a neutral atom.
Atomic number = number of protons = number of electrons
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
From the given options:
The elements having same number of protons will be the isotopes of same element.
Hence, the atom with 6 protons and 6 neutrons and an atom with 6 protons and 7 neutrons are the isotopes of same element.
There are certain rules to follow when naming covalent compounds. But first, let us look at the definition of Covalent Compounds.
<h3>
What are Covalent Compounds?</h3>
When covalent bonds aid the creation of a molecule, in which the atoms have at least one similar pair of valence electrons, a covalent compound is said to have been formed.
A very common example is water (H₂O)
<h3>
How are Covalent Compounds named?</h3>
To name a covalent compound, simply list the first element in the formula using the name of the element, then name the second element by adding the suffix "ide" to the stem of the second element's name.
If there is only one atom in the molecule of the first element, then no prefix should be added.
It is to be noted that if the second element in the compound is oxygen, then we should say:
- monox<em>ide</em> instead of monoox<em>ide</em> and
- triox<em>ide</em> instead of trox<em>ide</em>, all depending on how many atoms that are involved.
See the attached for the prefixes related to the various number of atoms in the compounds.
It is to be noted that the covalent compound to be named here is not stated hence the general answer.
