Answer is: D. it is always wet.
Tropical rainforests are rainforests that occur in areas of tropical rainforest climate, between 10 degrees north and south of the equator.
In tropical rainforest there is no dry season, all months have an average precipitation of at least 60 mm.
Tropical rainforests contain a lot animal species.
They have high levels of biodiversity, around 40% to 75% of all biotic species are in the rainforest.
Answer:
14.512g
Explanation:
Using the expression
mole = Number of molecules/6.022 x 10^23
mole of Fluorine = 2.30 x10^23/6.022 x 10^23
= 0.3819 mol
However,
mole = mass / molarmass
Mass of Fluorine = mole of Fluorine/ Molarmass of Fluorine
Molarmass of Fluorine = 18.998 x 2 = 37.996 g/mol
Mass of Fluorine = 0.3819mol/37.996g/mol
= 14.512g
First, we need the balanced equation: H₂ + Cl₂ ---> 2HCl
since not much information is given, I am assuming we are at STP and that 22.4 Liters= 1 mol
1) let's convert the volume to moles using the molar volume of a gas. also we need to convert the cm₃ to mL, then to Liters.
8 cm³ (1 ml/ 1 cm³)(1 L/ 1000 mL) (1 mol/ 22.4 Liters)= 3.6x10⁻⁴ moles of H₂
2) let's use the mole ratio of the balanced equation to convert moles of H₂ to moles of HCl
3.6x10⁻⁴ mol H₂ (2 mol HCl/ 1 mol H₂)= 7.1x10⁻⁴ mol HCl
3) lastly, we convert the moles of HCl to grams using the molar mass.
molar mass of HCl= 1.01 + 35.5= 36.51 g/mol
7.1x10⁻⁴ mol HCl (36.51 g/mol)=<span> 0.026 grams HCl</span>
No because most of them are forces
