When a strong base reacts with an acid what is always produced?

1 answer:

6 0

This really depends. When a strong base reacts with a strong acid, a neutralization reaction occurs, making H2O and neutralizing the pH of the substance. However, when a strong base reacts with a normal acid, nothing is always produced, and the solution will be slightly less basic.

What does each component of the punnet square represent

Mamont248 [21]

By convention maternal alleles are represented in first row and paternal alleles in first column (leaving the first square empty), thus each square shows the genotype of the progeny formed as the result of cross between corresponding alleles

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

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.
