Answer: A. dipole
Explanation:
Dipole can be defined as the separation of the equal and opposite charges present in the molecule via ionic bonding. The water molecule comprising of two molecules of hydrogen being positively charged and one molecule of oxygen being negatively charged are connected via ionic bonding thus water molecule is an example of dipole molecule. There is unequal distribution of the electrical density throughout the molecule.
Answer:
Explanation:
1)
H₂SO₄:
Element (symbol) No of atoms in No of compounds Total atoms
1 molecule coefficient
H 2 1 2
S 1 1
O 4 4
2)
2H₃PO₄:
Element (symbol) No of atoms in No of compounds Total atoms
1 molecule coefficient
H 3 2 6
P 1 2
O 4 8
There are two mole of H₃PO₄. One mole contain 3 hydrogen atom, 1 phosphorus atom and 4 oxygen atoms. Thus in two mole of compound 6 hydrogen atoms, 2 phosphorus atom and 8 oxygen atoms are present.
Hey it's me again haha!
the answer to your question is:
answer: so f=20.1
a=8.2
m=?
f=ma
20.1 = 8.2*m in
20.1/8.2=m
so the answer is around 2.45 something!
also i'm sorry this question had be stumbled!
Given :
Number of molecules of hydrogen peroxide, N = 4.5 × 10²².
To Find :
The mass of given molecules of hydrogen peroxide.
Solution :
We know, 1 mole of every compound contains Nₐ = 6.022 × 10²³ molecules.
So, number of moles of hydrogen peroxide is :
Now, mass of hydrogen peroxide is given as :
m = n × M.M
m = 0.0747 × 34 grams
m = 2.54 grams
Hence, this is the required solution.
Answer:
a system in chemical nomenclature and notation of indicating the oxidation state of the significant element in a compound or ion by means of a Roman numeral that is used in parentheses after the name or part of the name designating this element and ending invariably in -ate in the case of an anion and that is placed. Stock nomenclature for inorganic compounds is a widely used system of chemical nomenclature developed by the German chemist Alfred Stock and first published in 1919. In the "Stock system", the oxidation states of some or all of the elements in a compound are indicated in parentheses by Roman numerals.
