#8 would be radiation
Because of the heat it produces for the air in the home
#9 Conduction
Because it’s preventing physical heat transfer
#10 convection
Because it is stopping the air from rising
#11 Radiation
Because the heat is emitting from the stove and warms him, but not by direct contact
#12 Conduction
Because the heat transfers from the top of the stove to the cats fur.
#13 Conduction
Because the stove under it heats it through contact
#14 I think Radiation
Because the heat warms up the dish through the air in the oven
#15 Radiation
Because the heat is emitting from the fire.
#16 Conduction
Because the blanket is warming you through physical contact.
I’m not completely sure but the is the best I got. Good luck!
Answer:
The answer to your question is [H₃O⁺] = 0.025 [OH⁻] = 3.98 x 10⁻¹³
Explanation:
Data
[H⁺] = ?
[OH⁻] = ?
pH = 1.6
Process
Use the pH formula to calculate the [H₃O⁺], then calculate the pOH and with this value, calculate the [OH⁻].
pH formula
pH = -log[H₃O⁺]
-Substitution
1.6 = -log[H₃O⁺]
-Simplification
[H₃O⁺] = antilog (-1,6)
-Result
[H₃O⁺] = 0.025
-Calculate the pOH
pOH = 14 - pH
-Substitution
pOH = 14 - 1.6
-Result
pOH = 12.4
-Calculate the [OH⁻]
12.4 = -log[OH⁻]
-Simplification
[OH⁻] = antilog(-12.4)
-Result
[OH⁻] = 3.98 x 10⁻¹³
The atom's radius and mass increase from top to bottom. The density of elements from top to bottom also increases in a periodic table.
Density of Sn= Mass of Sn/Volume of Sn
=24.3968/7.28
=3.49 g/ml*ml/cm³
=3.49 g/cm³
It is accurate to assume that the density of Sn will fall between that of Si and lead . the mass number and radius of the atoms increase from group to group as we move from top to bottom in a periodic table.. The density rises because the increase in mass number is greater than the increase in radius. Simply multiplying by the molar mass of the gas allows one to derive the formula for mass density from the formula for number density. Do not forget that the mass is equal to the moles (n) times the molar mass (M). Smaller masses can be measured in grams instead of kilograms (kg), which is the standard SI unit for mass.
