Answer: Now that you see to some extent bit about place nonrenewable fuel sources come from, can you analyze in what way or manner the Sun’s light strength is ultimately being the reason for the strength in fossil fuels? Describe the way that light strength must enjoy become the synthetic strength in fossil fuels and therefore energetic energy. (Hint: Think about by means of what plants in an environment take their energy.)
Answer:
The number before any molecular formula applies to the entire formula. So here you have five molecules of water with two hydrogen atoms and one oxygen atom per molecule. Thus you have ten hydrogen atoms and five oxygen atoms in total.
Electronegativity increases as you move from left to right across a period on the periodic table.
The RDA for iodine in adults is 150 micrograms
To meet this, one must consume:
150 / 0.7645
= 196.2 micrograms of potassium iodide per day.
Answer:
Density = 1.11 g/cm³, will not float on water
Explanation:
Assuming the other dimension missing is 4.0 cm
Then we can find the volume of the piece of wood.
Volume = Length × width × height
Volume = 6.0 cm × 3.0 cm × 4.0 cm
= 72 cm³
We are required to find the density of the wood.
Density = mass ÷ Volume
Mass of the wood = 80.0 grams
Therefore;
Density = 80.0 g ÷ 72 cm³
= 1.11 g/cm³
Hence, the density of the wood is 1.11 g/cm³
Water has a density of 1 g/cm³ and therefore the wood will not float since it is denser than water.
