Answer:

Platelets are tiny blood cells that help your body form clots to stop bleeding.

Explanation:

If one of your blood vessels gets damaged, it sends out signals to the platelets. The platelets then rush to the site of damage and form a plug (clot) to fix the damage.

Platelets are only about 20% of the diameter of <u>red blood cells</u>. The normal platelet <u>count</u> is 150,000-350,000 per microliter of blood, but since platelets are so small, they make up just a tiny fraction of the blood volume. The principal function of platelets is to prevent bleeding.

s2008m [1.1K]

Answer:

<h3><em>A is most likely your correct answer</em></h3>

Explanation:

A. Hills Covered with dry brush- this is most likely correct

b. Hills covered in lush grass- incorrect, because it is LUSH grass which would require lots of rain.

c. Flat lands with little grass- incorrect because grasslands DO have lots of grass.

D- incorrect because grasslands typically do NOT have rocky mountains <u>but are generally flatlands with grass</u>

Nickel carbonyl decomposes to form nickel and carbon monoxide, like this:

Schach [20]

Answer: The value of the equilibrium constant for this reaction is $2.8\times 10^{-5}$

Explanation:

To calculate the moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}$

Moles of $Ni(CO)_4$ = $\frac{0.597g}{170.7g/mol}=0.0035moles$

Moles of $Ni$ = $\frac{12.7g}{58.7g/mol}=0.216moles$

Moles of $CO$ = $\frac{1.98g}{28.01g/mol}=0.071moles$

Volume of solution = 2.7 L

Equilibrium concentration of $Ni(CO)_4$ = $\frac{0.0035mol}{2.7L}=1.29\times 10^{-3}M$

Equilibrium concentration of $Ni$ = $\frac{0.216mol}{2.7L}=0.08M$

Equilibrium concentration of $CO$ = $\frac{0.071mol}{2.7L}=0.026M$

The given balanced equilibrium reaction is,

$Ni(CO)_4\rightleftharpoons Ni+4CO$

The expression for equilibrium constant for this reaction will be,

$K_c=\frac{[Ni]^1\times [CO]^4}{[Ni(CO_4]^1}$

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

$K_c=\frac{(0.08)^1\times (0.026)^4}{(1.29\times 10^{-3})^1}$

$K_c=2.8\times 10^{-5}$

Thus the value of the equilibrium constant for this reaction is $2.8\times 10^{-5}$
