krok68 [10]

I think the correct term to fill in the blank would be equal. According to the law of conservation of mass, when sodium, hydrogen, and oxygen react to form a compound, the mass of the compound is equal the sum of the masses of the individual elements. This particular states that the mass cannot be created nor destroyed. So, for every process, the total inflow of mass should be the same total mass for the outflow since mass should be constant all through out. So, for a reaction, the total mass of the reactants should be equal to the total mass of the products.

How is filtration done?<br> What is the difference between residue and filtrate?

LiRa [457]

Answer:

residue is whatever remains after something else has been removed while filtrate is the liquid or solution that has passed through a filter, and which has been separated from the filtride.

filtration id done by placing a filter paper on the beaker or container then pour the filtride then let it settle and it will pass through and you will have the fitrate and residue

calculate the number of oxygen atoms in a 90.0g sample of vanadium(v) oxide v2o5. be sure your answer has a unit symbol if neces

Alborosie

90.0 g of vanadium (V) oxygen sample has 1.50 x 10 24 oxygen atoms.

To determine the number of oxygen atoms in a vanadium oxide sample, the following steps must be made.

Step 1: Convert the mass of vanadium(V) oxide to mol of vanadium(V) oxide

mol vanadium(V) oxide = mass / molar mass

mol vanadium (V) oxide = 90.0 g / 181.88 g/mol

mol vanadium (V) oxide = 0.49483 mol

Step 2: Convert mol of vanadium (V) oxide to moles of oxygen using mole ratio

mol oxygen = mol vanadium (V) oxide * mole ratio O / mol V2O5

mol oxygen = 0.49483 mol * 5 mol O / mol V2O5

mol oxygen = 2.47416 mol O

Step 3: Convert to oxygen atoms using Avogadro's number

atoms oxygen = mol oxygen * 6.02214 x 10 23 atoms O /mol O

atoms oxygen = 2.47416 mol O * 6.02214 x 10 23 atoms O/mol O

atoms oxygen = 1.48997 x 10 24 atoms or 1.50 x 10 24 atoms O
