Answer:
Explanation:P = 1 mol x 30.97 g/mol = 30.97 g N = 2 mol x 14.01 g/mol = 28.02 g. O = 4 mol x ... 5.68 g O2 f. Molecules of water produced? 2.46 g H2O ×. 1 mol H2O. 18.02 g H2O. × ... How many grams of sodium sulfate will be produced by the complete ... 2 mol BF3. 3 mol H2. = 1.65 mol BF3 required. Calculate moles H2 required:.
Answer: B) Electromagnetic waves can travel through empty space.
Explanation:
Conduction: This type of heat transfer happens when there is direct contact between the two object. Example: heating a pan on stove.
Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas) due to the movement of hot layers to the top and cold layers to the bottom which leads to convection currents. Example: Heating of swimming pool.
Radiation: This type of heat transfer happens when there is direct transfer of energy through empty space.The electromagnetic radiation from the surface of an object which is due to the object's temperature is radiation. Example: Heating of earth's surface.
<span>Like many plants, most species of grass produce a bright pigment called chlorophyll. Chlorophyll absorbs blue light (high energy, short wavelengths) and red light (low energy, longer wavelengths) well, but mostly reflects green light, which accounts for your lawn's color.
</span>sky<span> is </span>blue<span> because molecules in the air scatter </span>blue<span> light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colors because the </span>blue<span> light has been scattered out and away from the line of sight.

Hope this Helped!
It has 4 pcs of Carbon (C) and 8 pcs of Hydrogen (H) so the formula is C4H8 - calls Butene.
Hope it helps!
