Answer:
With the distance allowing us a conversion from one to the other. Two stars can have the same apparent magnitude, but different absolute magnitude, if we measure the same amount of light from them, but they're at a different distance from the Earth.

Did the activities help you uderstand. the topic? Why?
The number of reactants is the same as the number of products is the best statement that describes the conservation of mass in chemical equation
<u>Explanation:</u>
- The conservation of mass conveys that the mass of an seperate system is neither destroyed nor created by the chemical reactions.
- Therefore there should be the same amount of matter when compared to the reactant and product side.
- If the reaction exists by satisfying the above condition it is said to be the balanced chemical equation.
- The Lavoisier stated the law on conservation of mass.
Answer:
5.79 × 10^23 Oxygen atoms
Explanation:
Number of Oxygen atom in the compound = 4×3 = 12
Molar mass of Al2(SO4)3 = 342 g/mol.
No of mole = mass/molar mass = 2.74/342 = 8.01×10^-03 mole
2.74g of Al2(SO4)3 × 1 mole of Al2 (SO4)3 / 342g of Al2 (SO4)3 * 12 mole of Oxygen/ 1mole of Al(SO4)3 * 6.02×10^23 Oxygen atom/ 1 mole of Oxygen
= 5.79×10^23 Oxygen atoms
I think 14 are produced because if you go up by that you get it
