Answer:
- 1. Iodine is the limiting reactant
- 2.
Explanation:
<u>1. Balanced chemcial equation:</u>
<u>2. Theoretical mole ratio</u>
It is the ratio of the coefficients of the reactants in the balanced chemical equation:
<u>3. Actual ratio</u>
<u />
It is ratio of the moles available to reat:
<u>4. Comparison</u>
Then, there are more aluminum available than what is needed to react with the 9 moles of iodine, meaning that the aluminum is in excess and the iodine will react completely, being the latter the limiting reactant.
Conclusion: iodine is the limiting reactant.
<u>5. How much aluminum iodide will be produced?</u>
Use the theoretical mole ratio of aluminum iodide to iodide:
Yes a recessive allele can hide their trait if a dominant allele is present.
Answer:
A. Creep
Explanation:
Creep is usually defined as a mass movement process where the rock and other particles are forced to move slowly downward along a slope that is mostly covered with softer sediments and broken rock fragments. It results in the tilting of trees, poles, and gravestones.
Answer:
0.924 g
Explanation:
The following data were obtained from the question:
Volume of CO2 at RTP = 0.50 dm³
Mass of CO2 =?
Next, we shall determine the number of mole of CO2 that occupied 0.50 dm³ at RTP (room temperature and pressure). This can be obtained as follow:
1 mole of gas = 24 dm³ at RTP
Thus,
1 mole of CO2 occupies 24 dm³ at RTP.
Therefore, Xmol of CO2 will occupy 0.50 dm³ at RTP i.e
Xmol of CO2 = 0.5 /24
Xmol of CO2 = 0.021 mole
Thus, 0.021 mole of CO2 occupied 0.5 dm³ at RTP.
Finally, we shall determine the mass of CO2 as follow:
Mole of CO2 = 0.021 mole
Molar mass of CO2 = 12 + (2×16) = 13 + 32 = 44 g/mol
Mass of CO2 =?
Mole = mass /Molar mass
0.021 = mass of CO2 /44
Cross multiply
Mass of CO2 = 0.021 × 44
Mass of CO2 = 0.924 g.
Answer:
random internal motion of atoms and molecule
Explanation:
The primary cause of diffusion is the random internal motion of atoms and molecules.
Randomness of atoms and molecules results in diffusion.
- Diffusion is the movement of particles from a region of high concentration to that of lower concentration.
- Substances often tend to spread out over the concentration gradient.
- Therefore, they have this propensity to be randomized.
