The concentration in /mmolL of the chemist's silver(I) nitrate solution is 0.01047 mmoles/litre.
Explanation:
Data given:
Number of moles of AgNO3 in micro mole 4.7102micromol.
The concentration is supposed to be in mmol so the micromole will be converted to milimole.
So, 1 micromole = 0.001 millimole
hence, 4.712micromole will be 0.004712 millimole.
Volume is given as 450ml which is converted into L
to convert ml into L it is divided by 1000
so 0.45 L is the volume.
Molarity or concerntration is calculated by the formula,
molarity =
putting the values in the formula:
molarity =
= 0.01047 mmoles/litre is the molarity of AgNO3 solution in 450 ml of solution.
While there is some restriction on rotation around a double bond, it is possible to rotate around a single bond. The C-N bond (shown by the arrow) acquires certain double bond characteristics through resonance. As a result, the C-N double bond prevents the bond from rotating.
<h3>What is a chemical bond?</h3>
A chemical bond is a strong bond that can be formed between atoms, ions, or molecules to create chemical compounds. In covalent bonds, the electrons are shared, whereas, in ionic bonds, the electrostatic attraction of two ions with opposing charges forms the link. In contrast to dipole-dipole interactions, the London dispersion force, and hydrogen bonding, which are examples of "weak bonds" or "secondary bonds," covalent, ionic, and metallic bindings are examples of "strong bonds" or "primary bonds."

Answer: The sign of ΔH° for the reaction is positive.
Explanation:
Given: = 155 kJ/mol (1 kJ = 1000 J) = 155000 J/mol
The relation between and is as follows.
As the given value of is positive. This means that on further calculation the value of will come out to be positive.
Thus, we can conclude that the sign of ΔH° for the reaction is positive.
A school bus would have what be longer than.
