Answer:

SiCl4 + 4H2O--->Si(OH4)+4HCl

Explanation:

<em>if </em><em>you</em><em> </em><em>put </em><em>a </em><em>4</em><em> </em><em>in </em><em>front</em><em> of</em><em> </em><em>H2O</em><em> </em><em>it </em><em>means </em><em>you </em><em>will </em><em>have </em><em>8</em><em> </em><em>hydrogens(</em><em>you </em><em>multiply</em><em> </em><em>4</em><em> </em><em>by </em><em>2</em><em>)</em><em> </em><em>then </em><em>the </em><em>oxygens</em><em> </em><em>will </em><em>be </em><em>4</em><em>.</em><em>.</em><em>on </em><em>the </em><em>other </em><em>side </em><em>that </em><em>hydrogen</em><em> </em><em>in </em><em>the </em><em>brackets </em><em>holds </em><em>it's </em><em>on </em><em>4</em><em> </em><em>so </em><em>that </em><em>4</em><em> </em><em>isn't</em><em> </em><em>for </em><em>both </em><em>the </em><em>hydrogen</em><em> </em><em>and </em><em>the </em><em>oxygen.</em><em>.</em><em>.</em><em>and </em><em>if </em><em>you </em><em>put </em><em>a </em><em>4</em><em> </em><em>in </em><em>front</em><em> of</em><em> the</em><em> </em><em>HCl </em><em>that </em><em>simply</em><em> </em><em>means </em><em>it's </em><em>for </em><em>both </em><em>the </em><em>hydrogen</em><em> and</em><em> </em><em>oxygen.</em>

<em>I </em><em>hope</em><em> this</em><em> helps</em>

A van moves with a constant speed
Kitty [74]

Answer:

1.5 hours or 90 minutes

Explanation:

Velocity = d/t

V = 64 mi / hour or 96 mi / 9 min OR 16 mi / 15 min

D = 96 miles

Velocity * Time = Distance

Time = Distance / Velocity

T = 96 mi / 64 mi / hour

96 / 64 = 1.5 mi per hour

T = 1.5 hours or 90 minutes

Which statement best describes the structure of covalent network solids? A. They are giant structures held together by weak forc
konstantin123 [22]

Answer: Option (B) is the correct answer.

Explanation:

A covalent compound is a compound formed by sharing of electrons. And, in a covalent network solid atoms are bonded by covalent bonds in a continuous network that is extending throughout the material or solid.

This continuous arrangement of atoms are like a lattice.

For example, diamond is a covalent network solid in which carbon atoms are arranged in a continuous lattice like structure.

Hence, we can conclude that the statement all the atoms are covalently bonded to other atoms to form a lattice-like structure, best describes the structure of covalent network solids.
