Answer:
1.3 kg
Explanation:
Mass of ocean water = mass of NaCl × (mass of ocean water/mass NaCl).
The % NaCl tells us there are 3.5 g NaCl/100 g ocean water or 100 g ocean water/3.5 g NaCl.
Mass of ocean water = 46.8 × (100/3.5)
Mass of ocean water = 46.8 × 28.6
Mass of ocean water = 1300 g = 1.3 kg
<em>Note</em>: The answer can have only <em>two significant figures</em> because that is all you gave for the percentage of NaCl.
Answer is: chemical elements<span> in </span>group 15<span> of the </span>periodic table have <span>neutral atom with a valence electron configuration of ns</span>²<span>np</span>³<span>.
</span>Nitrogen: [He] 2s² 2p³.
Phosphorus: [Ne] 3s² 3p³.
Arsenic: <span>[Ar] 3d</span>¹⁰ 4s² 4p³.
Bismuth: <span>[Xe] 4f</span>¹⁴ 5d¹⁰ 6s² 6p³.
Moscovium: predicted [Rn] 5f¹⁴<span> 6d</span>¹⁰<span> 7s</span>² 7p³.
These elements have 5 valence electrons.
Answer:
i dont think so
Explanation:
is there a image to explain this ? if so it would help ALOT
I believe the correct answer from the choices listed above is the second option. For liquids, it is the temperature that affects vapor pressure. <span>The </span>vapor pressure<span> of any substance increases non-linearly with </span>temperature<span> according to the Clausius–Clapeyron </span>relation<span>. Hope this helps. Have a nice day.</span>
