Answer:

covalent bond

Explanation:

Each C has 4 valance electrons and each C atom joins to four other C atoms to form a tetrahedral lattice. Each C atom has four sp³ hybrid orbital which are directed to the four corners of a tetrahedron. The tetrahedron unit cell gets repeated throughout the lattice thus forming a three dimensional network.

7. If a waste container has 87.0 mL of 0.234 M acetic acid, how many milliliters of 2.00 M sodium

Naya [18.7K]

Answer:

$V_{base}=10.2mL$

Explanation:

Hello.

In this case, since the neutralization of the acid requires equal number of moles of both acid and base:

$n_{acid}=n_{base}$

Whereas we can express it in terms of concentrations and volumes:

$M_{acid}V_{acid}=M_{base}V_{base}$

Thus, we can compute the volume of sodium hydroxide (base) as follows:

$V_{base}=\frac{M_{acid}V_{acid}}{M_{base}} \\\\V_{base}=\frac{87.0mL*0.234M}{2.00M}\\ \\V_{base}=10.2mL$

Best regards.

13. What is the total pressure inside the container

nasty-shy [4]

<u>Answer:</u> The total pressure inside the container is 77.9 kPa

<u>Explanation:</u>

Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.

To calculate the total pressure inside the container, we use the law given by Dalton, which is:

$P_T=p_{N_2}+p_{O_2}+p_{Ar}$
