the relative atomic mass of oxygen atom is 16. explain its meaning. answer. an atom’s relative atomic mass is its average mass as compared to one-twelfth the mass of one carbon-12 atom. q7. which part of dalton’s atomic theory came from the law of constant proportions given by ...
The number of protons present in an atom leads to the termatomic number. An atomic number 1 points out that the atom is hydrogen. Similarly, an atomic number 2 reveals helium atom. The total number of neutrons and protons, when added together, gives us the relative atomic mass. For ex...

X(s) and X2O3 (s) is allowed to react with 6M HCl(aq) . 0.0954dm3 of the acid is needed for both the metal and its oxide to undergo complete reaction.Based on this information , Deduce respectively the greatest value and the smallest possible value of the relative atomic mass of X...
True or False, based on the atom described in the question above, the valence of that atom is 1. 3. An atom with the atomic number 15 has a valence of . . . increases the hydrogen ion concentration of an aqueous solution. An acid is a substance that . . . 1000 A pH of 6 is ...
answer. the energy in a molecule’s chemical bonds is related to the molecule’s structure and the positions of its atoms relative to one another. as a result, chemical energy, or the energy stored in chemical bonds, is regarded as a type of potential energy. q11. how do plants store ...
For example, when measuring maximal isometric knee extensor moments, the contribution of a single muscle (let’s say the vastus lateralis) is often calculated based on its relative cross-sectional area [46]. So, if the relative physiological cross-sectional area of the vastus lateralis relative ...
providing a coarse-grained view of cell-based gene expression across the tissue. Cells may also be optically barcoded prior to sequencing assays to capture their relative location. Using these methods, the high-dimensional genomic state of a single cell can be measured, and the cell can subseque...
The relative mass of a neutron is almost 1 u. Neutron is a neutral particle and has no charge. 4) What is the atomic number of a chemical element? The atomic number of a chemical element is the charge number of an atomic nucleus. In other words, the number of protons in the nucleus...
cho. indicate the relative stability of the contributing structure. answer. the resonance structure of ch 2 = ch – cho is as follows- stability is i > ii > iii structure i is most stable because each carbon and oxygen atom has an octet and no charge separation is present on any of ...
