Answer:
V = 8.97×10⁴ L
Explanation:
Given data:
Mass of oxygen = 1.35×10⁵ g
Litters of oxygen = ?
Solution:
First of all we will calculate the number of moles.
Number of moles = mass/ molar mass
Number of moles = = 1.35×10⁵ g / 32 g/mol
Number of moles = 0.04 ×10⁵ mol
Litters of oxygen:
PV = nRT
V = nRT/P
V = 0.04 ×10⁵ mol × 0.0821 atm. L/ mol. K ×273 K / 1atm
V = 0.897×10⁵ atm.L / 1atm
V = 8.97×10⁴ L
Answer: base times height
Explanation:
<span>Answer: yes, when you balance a chemical reaction, you are making sure that the law of conservation of matter is obeyed.
</span>
<span /><span /><span>
Justification:
</span><span />
<span>1) When you balance a chemical reaction, you add the coefficients to make the number of atoms of each element in the left side of the equation (reactants) equal to number of atoms of the same elements in the right side (products).
</span><span />
<span>2) Since, each atom has a unique atomic mass associated, it results, necessarily, that the mass of the atoms of the reactants is equal to the mass of the atoms of the products</span>.
