There are 1.86 x 10²⁴ molecules of Silicon dioxide, SiO₂
<h3>Further explanation
</h3>
The mole is the number of particles(molecules, atoms, ions) contained in a substance
Moles can also be determined from the amount of substance mass and its molar mass
1 mol = 6.02.10²³ particles
Can be formulated
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
3.09 mol of Silicon dioxide, SiO₂
n=mol=3.09
Answer:
Weight,mass, volume, density
Answer:
A tick living on a dog and drinking it's blood = Parasitism
Birds that live among cattle too eat insects stirred up by grazing = Mutualism
A clownfish living on the tentacles of an anemone provides nutrients too the anemone, and the clownfish is protected from predators = commensalism
A bear catching and eating a salmon from the river = predation
A bobcat catching and eating a rabbit = predation
A tapeworm living on the digestion system of a horse = parasitism
A Egyptian plover eating bugs off a giraffe or rhino = Mutualism
Bees gathering nectar and then spreading pollen too a flower = commensalism

Explanation:
Hello,
In this case, since the ionization of methylamine is:
The equilibrium expression is:
And in terms of the reaction extent which is equal to the concentration of OH⁻ as well as that of CH₃NH₃⁺ via ice procedure we can write:
Whose solution for via quadratic equation is 9.24x10⁻³ M since the other solution is negative so it is avoided. Therefore, the concentration of OH⁻ is:
With which we can compute the pOH at first:
Then, since pH and pOH are related via:
The pH turns out:
