The law of conservation of mass states that mass is neither created nor destroyed during a chemical reaction. This can be gleane
svet-max [94.6K]

Answer:

Explanation:

The law of conservation of mass states that mass is neither created nor destroyed during a chemical reaction. This can be gleaned from the third postulate in Dalton's series. Magnesium oxide decomposes into magnesium and oxygen. If 4.03 g of magnesium oxide decomposes to form 2.43 g of magnesium, what mass of oxygen gas is also released in the reaction

The word say magnesium oxide decomposes to magnesium and oxygen

the chemical symbols say

MgO-----------> Mg + O2  (since natural oxygen is diatomic)

the balanced  equation says

2MgO-------------->2Mg + O2

4.03 gm----------> 2.43 + ?0 gms

tour high school Algebra I class says

? = 4.03 -2.43 =1.60

your chemical analytcal lab says %mO in MgO = 16/40.3 = 39.7%

your calculator says

39.7/100 X 4.03 = 1.60

all of these prove the law of conservation of mass

Our recorded observations are called.
trapecia [35]

Answer:  Raw data, perhaps.

Explanation:  I'm not certain what the question is seeking for an answer, but I would suggest "raw data" would be a reasonable choice.  It reflects the data was recorded, but not yet processed to provide a conclusion or observation.

If one were a bit snarky, other possiblities include

  • a pile of dung
  • my labmate's scrawls, or
  • the best web results I could find

Give the major force between ethanol and water. dipole-dipole dispersion hydrogen bonding ion-ion ion-dipole
Komok [63]

Answer:

HYDROGEN BONDING

Explanation:HYDROGEN BONDING is the major intermolecular force and interaction taking place when water and ethanol are mixed.

Hydrogen bond is a weak inter-molecular force of attraction which occurs when the partially charged Negative end of an oxygen atom from one oxygen molecule attracts and interacts with the partially charged Positive end of the Hydrogen atom in another Molecule, Hydrogen bonds are also known as dipole-dipole bonds.

What volume of 0.5 HCL contains 10 moles of HCL​
boyakko [2]

Answer:

20L

Explanation:

molar concentration = moles of solute ÷ volume of solution

⇒ 0.5 = 10 ÷ volume

⇒ volume = 10 ÷ 0.5 = 20L
