Which end of water molecule attracts most of the electrons and acts negative?
From H and O, oxygen is the most electronegative, so that the negative side of the H-O-H 'triangle' with O in top.
What can be said about a reaction with h=-890 kj/mol and s = -0.24 kj/mol?
It can be said to be exothermic since H is negative. Also below a temp of 3708ºC, the reaction will be spontaneous because ∆G will be negative. This is from ∆G = ∆H - T∆S.
Is it possible for the change in enthalpy, represented as H, to have a negative value in a chemical reaction?
Yes, it is possible for the change in enthalpy (H) to have a negative value in a chemical reaction, indicating that the reaction releases heat energy.
What could make delta G become negative at a given enthalpy and entropy?
For delta G to become negative at a given enthalpy and entropy, the process must be spontaneous. This can happen when the increase in entropy is large enough to overcome the positive enthalpy, leading to a negative overall Gibbs free energy. This typically occurs at higher temperatures where entropy effects dominate.
What does it mean when delta H is a negative number?
it means that heat is released during the reaction and a + delta H means that heat is required/absorbed.
What conditions make G always negative?
G is always negative when H is negative and S is positive.
Are chemical reactions always spontaneous when H is negative and S is negative?
No, when H and S are both negative, the reaction will only be spontaneous below a certain temperature
How do you simplify negative numbers?
You cannot simplify them. If they are negative they have to stay negative.
What is the derivative of h to the negative 1 power?
d/dh(h^-1) = -1(h^-2) = -(h^-2)
What does a negative H tell you about a reaction?
yes
What is 1 over h to the negative 8 power?
1/h-8 = (1/h)-8 = h8
What was a negative outcome of the Dawes Severalty Act?
h
What could make Delta become negative at a given enthalpy and entropy?
The equation for ∆G is ∆G = ∆H - T∆S H is enthalpy and S is entropySo, ∆G is negative if T∆S is greater than ∆H
What is negative h over 3 minus 4 equals 13?
-h/3 -4 = 13 -h -12 = 39 -h = 39+12 -h = 51 h = -51
Is H pylori Gram positive?
No. H. pylori is a gram negative, spiral shaped, aerobic bacteria.
What are the negative and positive effects of tourism in Spain?
it is basically
Which element can form both positive and negative ions?
Hydrogen is the element that can form both positive (H+) and negative (H-) ions. When hydrogen gains an electron, it forms a negative ion, and when it loses an electron, it forms a positive ion.
