Answer: Oxalic Acid is and
Arrhenius Acid.
Explanation: According to
Arrhenius Theory of acid and base, "Acid is any substance which when dissolved in water produces H⁺ Ions".
Therefore, Oxalic Acid is a diprotic substance, which is capable of donating protons in water. This acidity of oxalic acid can be dedicated to the stability of
conjugate base, this stability comes from resonance of the negative charges on
Oxalate ion. Below reaction shows the dissociation of Oxalic Acid into Protons and Oxalate Ion.
The answer is 2 because you have to divide these numbers.<span />
Answer:
B . Changing the material that the fluids container is made of
Explanation:
Changing the material of the container does not affect the pressure in a container whereas increasing the volume, changing the weight of the fluid, and heating/cooling the fluid will all change the pressure.
<h3>Answer:</h3>
The reactivity of an alkali metal depends on the metals ability to <u>loose an electron</u>.
<h3>Explanation:</h3>
Alkali metals are elements present in first group of the periodic table. Following are the metals from top to bottom;
Lithium
Sodium
Potassium
Rubidium
Cesium
Francium
These s-block elements are considered the most reactive metals in the periodic table because they have only one electron in their valence shell and readily loose that electron to form an ionic bond with non metal. The general electronic configuration of these metals is as follow,
nS¹
Also, the reactivity of these metals increases from top to bottom in the group as the ionization energy decreases due to increase in shielding effect respectively.
Answer:
Molecules are made of two or more atoms
Molecules range in size
Molecules are made of atoms of the same element or different elements.
