2. A sample of table sugar (sucrose, C12H22O11) has a mass of 1.202 g.
Snezhnost [94]

Explanation:

Given mass of sugar = 1.202 g

Molar mass of the sugar , C_{12}H_{22}O_{11} = 342.29 g/mol

a) Number of moles of sugar

\text{number of moles}=\frac{\text{given mass of sugar}}{\text{molar mass of sugar}}=\frac{1.202 g}{342.29g/mol}=0.0035 mol

Number of moles of sugar in 1.202 grams is 0.0035 moles

b)Moles of each element in C_{12}H_{22}O_{11}

In a molecular formula of sugar there are 12 carbon, 22 hydrogen and 11 oxygen atoms

Moles of an element in molecule =

number of atoms of that element in a molecular formula × number of moles of compound

Moles of carbon = 12 × 0.0035 = 0.042 moles

Similarly

Moles of hydrogen = 22  × 0.0035 = 0.077 moles

Moles of oxygen =11 × 0.0035 = 0.0385 moles

c) Number of atoms of each type in C_{12}H_{22}O_{11}

\text{Number of atoms}=\text{number of moles of that atom in a molecular formula}\times \text{Avogadro number}

Number of carbon atoms =0.042 mole\times 6.022 \times 10^{23}=2.52\times 10^{22} atoms

Number of hydrogen =0.077mole\times 6.022 \times 10^{23}=4.63\times 10^{22} atoms

Number of oxygen atoms = 0.0385 mole\times 6.022 \times 10^{23}=2.31\times 10^{22} atoms

Which two factors does the power if a machine depend on
Furkat [3]

The definition of mechanical power is


                       Power = (work done) / (time to do the work).


From that definition, it looks pretty much like the power of a machine

depends on work and time.

The geological time scale is divided up and organized according to what life forms existed on earth.
Ivanshal [37]

Answer:

true

Explanation:

Geologic time is divided into four large segments called Eons: Hadean, Archean, Proterozoic, and Phanerozoic. The Phanerozoic Eon isdivided into Eras: Paleozoic, Mesozoic, and Cenozoic. The divisions among Eras reflect major changes in the fossil record, including the extinction and appearance of new life forms.

What will most likely happen when two bromine atoms bond together?
Sholpan [36]
<span>Ionic bonding is the entire exchange of valence electron(s) between particles. It is a kind of substance security that creates two oppositely charged particles. In ionic bonds, the metal loses electrons to wind up plainly an emphatically charged cation, though the nonmetal acknowledges those electrons to end up noticeably a contrarily charged anion.</span>
