Answer:
O, N, C, H
Explanation:
Electronegativity of an element is the property that combines the ability of its atom to lose or gain electrons. It measures the relative tendency with which the atoms of the element attracts valence electrons in a chemical bond.
On the periodic table, Electronegativity increases across the period but decreases down a group.
To solve the given problem, let us use thE Pauling's table of electronegativities to compare the electronegativities of the elements.
On the table:
C = 2.5
H = 2.1
O = 3.5
N = 3.0
In terms of decreasing electronegativities, the atoms are arranged as:
O N C H
Answer:
Physical science is concerned with the study of natural, non living objects and life science is about living things.
Explanation:
I had fun answering this question.
Answer:
pH of buffer solution is 7.0
Initial pH of Weak acid is 3.27
Final pH of weak acid is 3.07
Amount of NaOH added is 1ml
Explanation:
Titration is a process in which acid and base are introduced together until a neutral solution is achieved whose pH value is near to buffer solution which is 7.0, the pH value for acid is below 7 while pH value for base is above 7.
Answer:
The atoms in the cup of coffee have more energy.
Explanation:
The difference between the hot cup of coffee and the piece of ice is their temperature. The hot cup of coffee has a higher temperature than the ice.
The relationship between the energy and temperature is a direct relationship. This means that higher temperature means higher kinetic energy and vice versa.
Since the hot cup of coffee has a higher temperature, it means it also have the highest amount of energy. The correct option is;
The atoms in the cup of coffee have more energy.
