Why is the moisture of cirrus clouds mostly in the solid state
MariettaO [177]

Answer:

Wind is the horizontal movement of air, transporting energy transferred from the earth's surface as sensible and latent heat. Sensible heat is transferred by the processes of conduction and convection. Conduction transfers energy within a substance, and convection transfers energy through the vertical movement of the heated substance. Latent heat is the transfer of energy by transforming the substance itself. As you recall, water has the ability to exist as liquid, gas or solid. The transformation from liquid to gas is called evaporation; the reverse process, from gas to liquid, is called condensation; from liquid to solid is known as solidification (freezing); and from solid to liquid, fusion (melting). Water can also be transformed directly from solid to gas (sublimation), or the reverse, through a process called deposition. We will see these various processes in the formation of clouds.

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
