At diverging plate boundaries, earthquakes occurs as the plates pull away from each other. Volcanoes form between the plates, as magma rises upward from the underlying mantle. Second, two plates may come together, at a converging plate boundary. Two situations are possible at converging plate boundaries.
For apex the answer is no solution
Elements always exist as pair of atoms called molecules .
Explanation:-
- The material which has only one types of similar atoms called element .
- Ex:-Sodium,Carbon etc
Diffusion is the process of a substance spreading out to evenly fill its container or environment. Kinetic energy of particles of matter increases with an increase in temperature. More the kinetic energy in the particles, more is the rate of diffusion. so diffusion is faster in the summer!
hope this helps!
Answer:
a. 167 mL.
b. 39.3 %.
Explanation:
Hello!
In this case, for the undergoing chemical reaction, since 45.0 g of aluminum react, based on the 2:3 mole ratio with sulfuric acid, we can compute the required moles as shown below:

Next, since the molarity of a solution is computed based on the moles and volume (M=n/V), we can compute the required volume of sulfuric acid as shown below:

That in mL is 167 mL.
Moreover, for the percent yield, we compute the grams of aluminum sulfate that are produced based on the required 2.50 moles of sulfuric acid:

Therefore the percent yield is:

Best regards!
