Answer: A
Explanation
The digestive tract carries out the function of peristalsis by moving food through the system. Peristalsis also removes excess liquid from the body. Chemical digestion breaks down food into small nutrients, but this process does not involve peristalsis. Finally, absorption of nutrients into the blood does not fall under the purview of peristalsis.
Answer:
4
Explanation:
The balanced equation for the reaction is as follows:
4Al + 3O2 --> 2(Al2O3)
Answer:What property do protons and electrons have that neutrons don't? Protons and electrons are charged particles. Neutrons have no charge. Why isn't it possible for an atom to have a mass number of 10 and an atomic number of 12?
Explanation:
<u>Answer:</u> The actual yield of the carbon dioxide is 47.48 grams
<u>Explanation:</u>
For the given balanced equation:

To calculate the mass for given number of moles, we use the equation:

Theoretical moles of carbon dioxide = 1.30 moles
Molar mass of carbon dioxide = 44 g/mol
Putting values in above equation, we get:

To calculate the theoretical yield of carbon dioxide, we use the equation:

Theoretical yield of carbon dioxide = 57.2 g
Percentage yield of carbon dioxide = 83.0 %
Putting values in above equation, we get:

Hence, the actual yield of the carbon dioxide is 47.48 grams
Answer:
second answer
Explanation:
The melting point would occur more quickly but stay the same.
So it is answer 2
