A.) burning fossil fuels contributes to climate change.
There are three different types of intermolecular forces in terms of strength. They are (strongest to weakest) hydrogen bonding, dipole-dipole and Van der Waals' forces.
Answer:
The final temperature is 20.3 °C
Explanation:
Considering that:-
Heat gain by water = Heat lost by brass
Thus,
Where, negative sign signifies heat loss
Or,
For water:
Mass = 300.0 g
Initial temperature = 20.0 °C
Specific heat of water = 4.184 J/g°C
For brass:
Mass = 19.0 g
Initial temperature = 81.7 °C
Specific heat of water = 0.375 J/g°C
So,


<u>Hence, the final temperature is 20.3 °C</u>
Well protists quite very as organisms i.e it is hard to say if an organism is a protist. Some main features of protists are that they have
1. A membrane enclosed nucleus
2.They are mainly single celled
Also protista are found mainly anywhere water is present for example damp soil, pools and lakes.
Hope this helps :).
Answer:
8 Toal valence electrons.
Explanation:
For CH4 you have a total of 8 total valence electrons. Drawing the Lewis structure for CH4 (named methane) requires only single bonds. It's one of the easier Lewis structures to draw.
