this is so ez,
ok so here what u'll do after u balance the equation:
1. convert grams of oxygen to moles of oxygen.
2. convert moles of oxygen to moles of water
3. convert moles of water to grams of water.
4. bOOm... that's your answer
as follows:
2H2O(l)===>2H2(g)+O2(g)
1. 151200(g)/16(g/mol)=9540 moles of O2
2. 9450 moles of O2 × 2 moles of H2O =18900 moles of H2O
3. 18900 moles of H2O × 10g/mol = 189000g of H2O is required.
The answer to this item is determined by using the proper conversion factors and the dimensional analysis. For the given units, meter and centimeters, the conversion from millimeters are as shown below,
1 m = 1000 mm
1 cm = 10 mm
Conversion of 5.3 mm³ to m³.
= (5.3 mm³)(1 m/1000 mm)³ = 5.3 x 10⁻⁹ m³
Conversion of 5.3 mm³ to cm³.
= (5.3 mm³)(1 cm/10 mm)³ = 5.3 x 10⁻³ cm³
The answer to this item is therefore letter B. 5.3 x 10⁻⁹ m³.
If you mean m (subscript l) is (-2,-1,0,1,2)
its a 3d orbital so it can hold 2 electrons, however, like in an electron diagram a 3d orbital has 5 boxes can can hold 2 electrons that is how i got 10 total but if you mean just in box 2 then only 2 can share it.
Does that make sense?
Answer:
“A” since liquid has to above 32F
Answer:
C. polarity
Explanation:
Water is polar that is why it is a universal solvent.
