For example:

5Cl₂ + I₂ + 12NaOH = 10NaCl + 2NaIO₃ + 6H₂O

Na₂S₂O₃ + 4I₂ + 10NaOH = 8NaI + 2Na₂SO₄ + 5H₂O

Slow cooling of magma results in the formation of c. coarse-grained textured rocks. An example of a coarse grained textured rock formed in this fashion is granite. As the rate of cooling of igneous rocks increases, the size of the crystal that is formed decreases. The Bowen's reaction series shows the different rocks cooled at different rates.

Heptane and water do not mix, and heptane has a lower density (0.684 g/mL) than water (1.00 g/mL). A 100-mL graduated cylinder w

kicyunya [14]

Answer:

$h=100.8cm$

Explanation:

Hello,

In this case, considering the density and mass of both water and heptane we first compute the volume of each one:

$V_{water}=\frac{m_{water}}{\rho _{water}}=\frac{34g}{1.00g/mL}=34mL\\ \\V_{heptane}=\frac{m_{heptane}}{\rho _{heptane}}=\frac{34.6g}{0.684g/mL}=50.6mL\\$

Now, the total volume is:

$V=50.6mL+34mL=84.6mL$

Which is equal to:

$V=84.6cm^3$

Then, by knowing that the volume of a cylinder is πr²h or π(D/2)²h, we solve for the height as follows:

$h=\frac{V}{\pi (D/2)^2} \\\\h=\frac{84.6cm^3}{\pi (3.16cm/2)^2} \\\\h=100.8cm$

Best regards.
