Answer:
179.4306 g
Explanation:
Given that:
Mass of 
= 198 g
Molar mass of = 465.96 g/mol
The formula for the calculation of moles is shown below:
Thus,
From the balanced reaction,
1 mole of on reaction produces 2 moles of bismuth
So,
0.4293 mole of on reaction produces 2 × 0.4293 moles of bismuth
Moles of bismuth = 0.8586 moles
Molar mass of bismuth = 208.9804 g/mol
<u>So, mass of bismuth = Moles × Molar mass = 0.8586 × 208.9804 g = 179.4306 g</u>
Answer:
solo I
Explanation:
Según esta teoría para que se produzca una reacción deben cumplirse tres condiciones: Las moléculas de los reactivos tienen que chocar entre sí. Estos choques deben de producirse con energía suficiente de forma que se puedan romper y formar enlaces químicos.
Answer:
the amount of product and reactant remains constant because the rates of the foward and reverse reactions are equal
Explanation:
Answer:
69.726 amu
Explanation:
From the question given above, the following data were obtained:
Isotope A:
Mass of A = 68.926 amu
Abundance of A (A%) = 60.00%
Isotope B:
Mass of B = 70.925 amu
Abundance of B (B%) = 40.00%
Average atomic mass =?
The average atomic mass of the element can be obtained as shown below:
Average atomic mass
= [(Mass of A × A%)/100] + [(Mass of B × B%)/100]
= [(68.926 × 60)/100] + [(70.925 × 40)/100]
= 41.3556 + 28.37
= 69.726 amu
Therefore, the average atomic mass of the element is 69.726 amu
C. "A" mentions that the drug killed all of the bacteria that are resistant to the drug, and that doesn't make any sense. "B" claims that all bacteria are resistant to the drug. This is not true. "D" mentions that bacteria eat the drug, which doesn't happen.
