What is the smallest atom in the second row of periodic table?
The smallest element known to man is Hydrogen (H).
Where is hydrogen on the periodic table?
It is at the very top left column. Hydrogen is the first element.
How many water molecules are produced during dehydration synthesis of a fat molecule?
Three water molecules are formed. They form from the leftover hydrogen and oxygen atoms left over from the triglyceride formation.
Where are unsaturated fatty acids found?
C
Does nuclear fission occur in the heavier elements after a star's death?
I believe that yes, it should occur - assuming any atoms are left. Please note that in the case of a neutron star, most of the atoms are crushed out of existence - i.e., there are no more atoms left, except a few in the outermost layers. Similarly, in a black hole, no atoms will be left.
How many hydrogen atoms are on the left side of the photosynthesis equation?
twelve I think
If five atoms of hydrogen are reactants in a chemical reaction then how many atoms of hydrogen will be found in the products of that reaction?
Mass is conserved in a chemical reaction, so the mass before must equal the mass after. If you have five atoms before, you must have five atoms after.
How can I tell if a chemical reaction is balanced or not balanced?
If the equation has the same number of each type of atom on both sides of the arrow, it is balanced. If the number of atoms on each side of the arrow is not the same, the equation is not balanced. For example, in the equation H2 + O2 -->H2O, there are two hydrogen atoms and two oxygen atoms on the left, and two hydrogen atoms and one oxygen atom on the right. Therefore, the equation is not balanced. However, in the equation 2H2 + O2 -->2H2O, there are four hydrogen atoms and two oxygen atoms on the left and four hydrogen atoms and two oxygen atoms on the right, so the equation is balanced.
What is the smallest atom in the second row of periodic table?
The smallest element known to man is Hydrogen (H).
What is sulfuric acid and its uses?
an acid donates a proton to a neighboring atom. (adds Hydrogen to water for example>) this in turn lowers the pH which is the amount of hydrogen in a substance. so, sulfuric acid is H2SO4 the H2 means there are 2 hydrogen atoms, and the SO4 means Sulfur atom and 4 oxygen atoms, this is what will be left when the 2 hydrogen atoms leave it, usually only one does so you are USUALLY left with a Hydrogen sulfur and 4 oxygens. since it is missing the hydrogen you are left with a negative charge on the molecule (H SO4), this can be used in many many reactions, and it is used for so many things you may just want to google uses of sulfuric acid.
What is made out of hydrogen?
i was looking at my brother's homework and it asked that question and he left it blank. can u list some organic molecules? there is a multitude of molecules that contain hydrogen and carbon and any molecule containing this combination is said to be organic. molecules not containing carbon and hydrogen are called inorganic.
How do you check that an equation is balanced?
Make sure that the number of atoms on the left side of the equation is the same as the number of atoms on the right side.For example: -H + O2 --> H2O This is not a balanced equation because there is more oxygen and less hydrogen on the left side of the equation then is needed on the right side.4H + O2 --> 2H2O This equation is balanced because there is 4 hydrogen atoms and 2 oxygen atoms on both sides of the equation.
What are arrangement of atoms by increasing atomic number?
The arrangement of atoms by increasing atomic number are shown in the periodic table.This can be seen from starting at H (Hydrogen) which has the smallest number of atoms and continues on from left to right.
Can water be formed by mixing hydrogen and oxygen?
If you mix hydrogen and oxygen then set the mixture on fire, you'll get water. The ratio is 2 parts hydrogen atoms to one part oxygen atoms--or really one H2 molecule plus one oxygen atom because that's how hydrogen comes from the welding store you bought it from. If there's too much hydrogen you'll have some left over; too much oxygen and you'll have some of it left over.
What does balance the equation mean?
In terms of Chemistry it means to make sure that there are equal numbers of atoms on both sides of the equation. For example, H2O2 +O2 = OH + O2 is not balanced as there are only four atoms of oxygen and two atoms of hydrogen on the left, and there are 3 atoms of oxygen and an atom of hydrogen on the right. To balance it, you make it so that it looks like this: H2O2 + O2 = 2OH + O2. Now, you have 2 atoms of hydrogen on the left with four atoms of oxygen, and 2 atoms of hydrogen on the right with four atoms of oxygen. Here is another balanced equation: 6 CO2 + 12 H2O + energy → C6H12O6 + 6 O2 + 6 H2O Carbon dioxide and water plus energy yields sugar, oxygen, and water. This essential chemical reaction is known as photosynthesis.
What happens to oxygen when hydrogen is removed from h2o?
The oxygen atoms left behind from the water molecules join into diatomic oxygen molecules.
Why does 2H2 plus O2 equal 2H2O If H2 has two atoms and O2 has four atoms shouldn't it all equal 2H4O?
Hydrogen has a valence of 1, meaning each hydrogen atom must form one chemical bond to become stable. Oxygen has a valence of 2. So it is fairly easy for two hydrogen atoms to bond with one oxygen atom.
