1 mol off sulfur atoms has how much mass?
The molar mass of sulfur is approximately 32.06 grams/mol. Therefore, 1 mol of sulfur atoms will have a mass of 32.06 grams.
When the surface of a piece of chalk is scrapped the tiny particles that flake off are knwn as?
When the surface of a piece of chalk is scrapped the tiny particles that flake off are known as. A. Matter B. Molecules C. Elements D. Atoms…….. The flakes are particles of whatever the chalk is made of (calcium sulphate or carbonate plus a binding agent)…I needn’t remind you that atoms and molecules are not visible to the naked eyes...If the chalk is white, the flakes falling off are also white. Again atoms have no colors. Although molecules have characteristic colors, they can’t be seen with unaided eyes.. Now let’s assume the chalk is made up of a single compound let’s say Calcium sulphate (made up of Calcium, Sulphur and Oxygen elements)..individually and independently the smallest bit of a compound capable of independent existence is a molecule, the molecules in turn are made up of atoms of elements CHEMICALLY BOND TOGETHER. One cannot separate the atoms just by scrapping the chalk as they are again Chemically bonded. Notice how I used the word ATOMS for ELEMENTS and MOLECULES for COMPOUND. Meaning an ATOM is the smallest unit of matter that retains all the chemical properties of an ELEMENT and Molecule the smallest unit of a compound capable of independent existence, retaining all properties of that compound or Simply a group of atoms chemically bounded together…Again, the flakes settle on standing which suggests that they are actually PARTICLES, not ATOMS, not MOLECULES not ELEMENTS. PARTICLES is the most appropriate ANSWER to the above question..
What will happen to the atoms and molecules of a substance when it undergoes a chemical reaction?
During a chemical reaction, atoms in the molecules rearrange to form new substances with different chemical properties. Bonds between atoms are broken and new bonds are formed, resulting in the creation of new molecules. Mass is conserved in a chemical reaction, meaning the total number of atoms remains the same before and after the reaction.
How many atoms are in hs2?
'hs2' ??? Have you got this correct. Should it be H2S.,which is hydrogen sulphide. . The are three atoms in H2S 2 x H = 2 x hydrogen 1 x S = 1 x sulphur. hydrogen sulphide has the smell of 'rotten eggs', which is the gas that rotten eggs give off.
When you burn polythene would you get more molecules of carbon dioxide more water or the same number of molecules of each?
you would get more water molecules because for every carbon particle there are 2 water molecules... hey did u get this off a science work-sheet from school? Yeah i'm doing the same question right now.

What are some common scientific beliefs?
The world is round. Gravity keeps us from falling off the planet into space. All matter is made from molecules. All molecules are made from atoms.
How are reactant atoms and molecules different to their products atoms and molecules?
Reactant atoms and molecules are the starting materials in a chemical reaction, while product atoms and molecules are the substances formed as a result of the reaction. During the reaction, reactant atoms and molecules are rearranged and transformed into new products with different chemical properties. The number and types of atoms remain the same, but their arrangement and interactions change.

What is helium made up off?
Atoms of Helium !
What is the Lewis structure for SbBr3?
The Lewis structure of SbCl5 has the Sb in the center with 5 Cl molecules branching off like a star. The branches of the molecules should be drawn as straight lines.

Why does stars start off as dust and gas?
because they were made from hot atoms
Are stars made of cells?
No. Standard sized young Stars are made up of hydrogen atoms fusing themselves into helium atoms and giving off lots of Energy.
