Answer:
54 grams of H₂O
Explanation:
4NH₃ + 3O₂ → 2N₂ + 6H₂O
Ratio is 4:6.
Let's convert the mass of ammonia in moles
Mass / Molar mass = Mol
34 g / 17 g/m = 2 moles
If 4 moles of ammonia are needed to produce 6 mol of water
2 mol of NH₃ will produce ( 2 .6 )/4 = 3 moles
Molar mass water = 18 g/m
Mass = mol . molar mass → 3 m . 18 g/m = 54 grams
The ozone layer protects humans from harmful UV rays, because it acts as a sort of filter for any toxic or overpowering waves from damaging our skin. This goes for animals, as well.
Quantitative data can be counted, measured, and expressed using numbers. Qualitative data is descriptive and conceptual.
<span>he density of a material is defined as its mass per
unit volume. In this example, each volume of water is different and
therefore has a specific and unique mass. The mass of water is expressed
in grams (g) or kilograms (kg), and the volume is measured in liters (L), cubic centimeters (cm 3), or milliliters (mL).</span>
H and Br are both non-metals which means the bond that comes in between them is covalent. If the composing elements are non-metal and metal, then the bond should be ionic. In this case, HBR is considered polar because the Br atom pulls on the electron much harder than the H atom. Answer is C.
