What is the relationship between the salinity and density of ocean water?

White raven [17]

As density increases, the amount of salt or salinity increases. Salinity can decrease from the melting of ice or increase from the freezing of ice<span />

Chlorine radicals perform the first propagation step:

Black_prince [1.1K]

Answer:

b. radicals form easily in the presence of chlorine radicals.

Explanation:

Chlorine radicals perform the first propagation step: because "radicals form easily in the presence of chlorine radicals."

This is because the first propagation step consumes a CHLORINE RADICAL while the second propagation step regenerates a CHLORINE RADICAL. In this way, a chain reaction occurs, whereby one CHLORINE RADICAL can ultimately cause thousands of molecules of methane to be converted into chloromethane with C12 present.

Hence, in this case, the correct answer is that "radicals form easily in the presence of chlorine radicals."

Find the density of a block with a length of 8.0 cm, a width of

seraphim [82]

Answer:

<h3>Density = 0.5 g/cm³</h3>

Explanation:

Density of a substance can be found by using the formula

$Density = \frac{mass}{volume}$

From the question

mass = 32g

To find the density we must first find the volume of the block

From the question the block is a cuboid

Volume of cuboid = length × width × height

length = 8 cm

width = 4 cm

height = 2 cm

Volume of block = 8 × 4 × 2 = 64 cm³

Substitute the values into the above formula and solve for the density

That's....

$Density = \frac{32}{64} \\ = \frac{1}{2}$

We have the final answer as

Density = 0.5 g/cm³

The block will float because it's density is less than the density of water which is

1 g/cm³

Hope this helps you

Determine how the following bonds are made using Lewis dots structures

garri49 [273]

Answer :

1.) $Ca^{2+}+2Cl^-\rightarrow CaCl_2$

Calcium has 2 valence electrons and chlorine has 7 valence electrons. For neutral molecule, 2 chlorine atoms share their valence electrons with 1 calcium atom. The bonds are formed between the calcium and chlorine atom.

2.) $Al^{3+}+3F^-\rightarrow AlF_3$

Aluminium has 3 valence electrons and fluorine has 7 valence electrons. For neutral molecule, 3 fluorine atoms share their valence electrons with 1 aluminium atom. The bonds are formed between the aluminium and fluorine atom.

3.) $H^{+}+Cl^-\rightarrow HCl$

Hydrogen has 1 valence electron and chlorine has 7 valence electrons. For neutral molecule, 1 chlorine atom share their valence electrons with 1 hydrogen atom. The bonds are formed between the hydrogen and chlorine atom.

4.) $2H^{+}+S^{2-}\rightarrow H_2S$

Hydrogen has 1 valence electron and sulfur has 6 valence electrons. For neutral molecule, 2 hydrogen atoms share their valence electrons with 1 sulfur atom. The bonds are formed between the hydrogen and sulfur atom.

5.) $Cl^{-}+Cl^-\rightarrow Cl_2$

Chlorine has 7 valence electrons. For neutral molecule, 1 chlorine atom share their valence electrons with 1 chlorine atom. The bonds are formed between chlorine and chlorine atom.

The lewis-dot structure image is shown below.
