lys-0071 [83]3 years ago
3 0
1) Silicon dioxide formula: SiO2  ....... 2 is a subscript for the O atom

2) From the formula you have 1 molecula of SiO2 contains 1 atom of SiO2

3) Then, 0.100 mol of SiO2 contains 0.1 mol of Si

4) Multiply by Avogadro's number: 0.100mol *  6.022*10^23 atoms/mol= 6.02*10^22 atoms

Answer: 6.02*10^22 atoms

What type of chest tube system does this statement describe?
Komok [63]

Answer:

<em>Dry suction chest tube system</em>

Explanation:

<em>The dry suction drains that are self-regulating today use a small, adjustable regulator installed into the drain. </em>

So long as there is enough air flow from the suction of the wall (that will be shown on the drain) it will respond correctly to changes in the pressure of the source or the patient to retain suction at the drain level.

It's also a quiet mode of activity.

16. A small piece of silver was placed in a solution containing both magnesium nitrate and copper(II) nitrate.
sashaice [31]
I believe it's about the dislodging response as Ag structures solvent salt with nitrate. For dislodging response, more receptive metal will uproot less receptive metal from the arrangement. In your question, the reactivity of the metal are positioned as takes after: Mg > Cu > Ag. Take note of that more responsive metals, that are Mg and Cu, are in the arrangement.
