Answer:
How many atoms of each element are there in one molecule of H3PO4? there are 8 atoms in total in H3PO4. there are 3 atoms of hydrogen, 1 atom of phosphorous and 4 atoms of oxygen in the one molecule of this compound, which is called hydrogen phosphate.
Answer:
Achol
Explanation:
Reduction of other aldehydes gives primary alcohols. Reduction of ketones gives secondary alcohols. The acidic work-up converts an intermediate metal alkoxide salt into the desired alcohol via a simple acid base reaction.
They are called isotopes.
Isotopes have the same number of electrons and protons in their unionized state. They differ in the number of neutrons. The first and simplest example is hydrogen.
The most common hydrogen has
1 proton
1 electron and
0 neutrons
It has 2 cousins
1 proton
1 electron
1 neutron
And
1 proton
1 electron
2 neutrons.
Most elements have some differences in the number of neutrons present in their nuclei. Cesium and Xenon have the most number of isotopes. Each has 36. You wonder how the atoms are held together.
A chemical change alters the chemical makeup of a substance. So, wood burning would be a chemical change. The others just alter the physical makeup of the substance.
The moon would have appeared more vividly and brightly due to the absence of light pollution and smog
