Answer:
<em>heterogeneous mixture is a mixture that is non-uniform and contains smaller component parts.</em>
Scientists have predicted that long-term effects of climate change will include a decrease in sea ice and an increase in permafrost thawing, an increase in heat waves and heavy precipitation, and decreased water resources in semi-arid regionsClimate change affects human health and wellbeing through more extreme weather events and wildfires, decreased air quality, and diseases transmitted by insects, food, and water.Most people of the world feel that climate change is likely to destroy the world's economy, flood cities, cause mass migrations and even cause regional wars. More than half of the world also feels that climate change will cause a new world war, although Europe and the United States think that is less likely
Answer:
Attraction
(e-) ---> <--- (H+)
Repulsion:
<---(e-) (e-)-->
Neutral:
(e-) (Helium)
Explanation:
Accordingly to coulomb's law:
In the attraction, the hydrogen without an electron has a positive charge and needs to be fulfilled with a negative charge found in an eletron.
In the repulsion, both electrons has the same charge and repulse each other.
In the neutral case, the Helium is highly stable therefore the electron is not attracted.
Lewis diagram:
well first you have to know the Valence electrons the elements which will on top of the periodic table.
for examples:
H2O
it will be O-H-O and the dots will on top. oxygen have 6 valence electrons so that mean it need 6 dots. also for H it will have 7 V-electrons.
