It should be 8 O atoms. 3O atoms in Na2S2O3 and 5O atom in 5H2O. The reason there are 5 O atoms are because the 5 in front of H2O means you multiply each atom in the compound by that number (like the distributive property). The H2 molecule becomes 10 Hydrogen atoms (5*2) and the Oxygen becomes 5 Oxygen atoms (5*1). Then you add the 5O atoms to the 3O atoms which equals 8
Answer:
1. electrons and neutrons protons
2. true
3. electrons are negative and neutrons are neutral
4. true
5. the total number of neutrons and protons
Explanation:
Answer:
Plasma
Explanation:
Plasma is a substance which is extremely hot. The heat present in plasma, a gas, is provided as energy in order to split electrons and protons apart. Therefore, ions and electrons are formed as products. Plasma is a synonym to an 'ionized gas'.
Normally, the standard states, gases, liquids and solids, wouldn't produce such an outcome, as not enough energy is present to perform the splitting pattern. This can only occur for gases at extremely high temperatures.
Answer:4
Explanation: because its ez
The number of particles (molecules, atoms, compounds, etc.) per mole of a substances is known as Avagadro number. It is equal to 6.022×10^23 mol-1 and is expressed as NA.
Number of moles is the amount of a substance that contains as many particles as there are atoms in 12 grams of pure carbon-12. So, 1 mol contains 6.022×10^23 elementary entities of the substance. Since 6.022 x 10^23 is the Avagadro number, one mole is equal to Avagadro number.
One mole of a substance is the ratio of mass of the substance by the molecular mass of the substance. Thus the mass of one mole of a substance is equal to the substance's molecular weight. Thus one mole of a substance is the atomic mass unit of a substance and since one mole is equivalent to the Avagadro number,we can conclude that one Avagadro number is one atomic mass unit of the substance.
