Fatty acid with only single covalent bonds is said to be
ohaa [14]
These are known to be saturated.  
The definition of a saturated fatty acid is that the carbon chain coming off of the acid group contains only single bonds.  An unsaturated fatty acid contains at least one double bond in the carbon chain coming off of the acid group.  Saturated fats are usually fats (solid at room temperature) while unsaturated fats can be oils (liquid at room temperature) this is because the single bonds in the saturated fats give the molecule a shape that can stack on another saturated fat molecule more easily which makes the melting points higher.  The double bonds (usually referring to cis double bonds since trans double bonds are in trans fats) in unsaturated fats give the molecule a shape that cannot stack on another unsaturated fat molecule easily which makes the melting point lower.

I hope this helps.  Please let me know if anything is unclear or if you want further explanation.

S<br> SIO₂ +3C Sic +20o<br> Sic ? mass in grams<br> С c-
seraphim [82]

Answer:

26.74g

Explanation:

The equation of the reaction is;

SIO₂ + 3C --> SiC +2CO

From the balanced equation, the relationship between SiC and C is;

3 mol of C produces 1 mol of SiC

Converting mol to mass using; Mass = moles * Molar mass

Mass of SiC = 1 mol * 40.11 g/mol = 40.11g

This means;

3 mol of C produces 40.11g of SiC

2 mol of C produces xg of SiC

3 = 40.11

2 = x

x = 2 * 40.11 / 3 = 26.74g

If 1.0 M HIM HI is placed into a closed container and the reaction is allowed to reach equilibrium at 25∘C∘C, what is the equili
sattari [20]

The given question is incomplete. The complete question is

If 1.0 M HI is placed into a closed container and the reaction is allowed to reach equilibrium at 25∘C∘C, what is the equilibrium concentration of H2 (g). Given the equilibrium constant is 62.

Answer: The equilibrium concentration of H_2 is 0.498 M

Explanation:

Initial concentration of HI = 1.0 M

The given balanced equilibrium reaction is,

                         2HI(g)\rightarrow H_2(g)+I_2(g)

initial                  (1.0) M                  0              0

At eqm               (1.0-2x) M               (x) M      (x) M

The expression for equilibrium constant for this reaction will be,

K_c=\frac{[H_2]\times [I_2]}{[HI]^2}

Now put all the given values in this expression, we get :

62=\frac{(x)^2}{1.0-2x}

By solving we get :

x=0.498M

Thus the equilibrium concentration of H_2 is 0.498 M
