I recently wrote a paper on animal testing
Pretty sure it was Galen
The reaction must be a + b --> c
Then you can predict a reaction rate, r o the type r = k * a^n * b^m
Given that the reaction rate is not affected by the concentration of b you can state that m = 0 and r = k * a^n.
Now given, that there is a proportional relation between the reaction rate and a (double a gives double rate), then n = 1 and r = k*a. You can verify that if you dobule a r also doubles.
Answer: r = k*a
Answer:
Cl EN < O EN < F EN
Explanation:
Electronegativity is a periodic property that indicates the tendency of an atom to attract electrons when combined with another element. It is very useful for predicting the type of bonding of compounds, so it is not possible to talk about electronegativity in elements in a fundamental state.
In the periodic table the electronegativity increases diagonally and the values were established in the so-called Pauling scale.
It is expected that elements with high electron affinity and high ionization energy possess considered electronegativity, so the group of nonmetals have high electronegativity, in fact flour is the most electronegative element
Answer : The correct option is, electrons are not shared equally between atoms.
Explanation :
Polar covalent bond : It is a type of chemical bond in which a pair of electrons are not shared equally between the two atoms.
In polar covalent bond, the electrons are not shared equally because one atom spends more time with the electrons than the another atom. In this, one atom has more tendency to pull an electron than the other atom.
For example :
is an example of polar covalent bond. In water molecule, oxygen spends more time with the electron than the hydrogen and oxygen carries a partial negative charge.
