Answer:
Some of the various things that humans do to the environment is pump CO2 into the air with Fossil Fuels and using Power Plants, Cutting down trees make more CO2 which can make the Earth hotter and cause Global Warming. Some natural things that can tend to affect climate can be changes in Volcanic activity, Solar activity with the sun, and Earth's orbit around the sun.
Explanation:
It may seem crazy how Earth's orbit around the sun make climate change, but how else would 4 seasons exist. The orbit tends to be in an oval shape. The top parts of the oval, would represent winter and fall because of the distance between the sun decreases. The closer sides of the oval however, would represent Summer and spring because those are the warmer months and show that Earth is closer to the sun.
Answer: New concentration of 
is 0.23 M.
Explanation:
The given data is as follows.
Moles of = 0.06 mol
Moles of 
= 0.08 mol
Therefore, moles of 
added are as follows.
Moles of = 
= 0.003125 mol
Now, new moles of = 0.06 + 0.003125
= 0.063125
Therefore, new concentration of will be calculated as follows.
Concentration = 
= 0.23 M
Thus, we can conclude that new concentration of is 0.23 M.
What are you solving for?
C
H
I
R
Answer:
Option C
Explanation:
The heat released by the system is absorbed by the surroundings, then only the heat will be balanced.
The surrounding heat increases and so to balance that heat the system releases heat so that it can cool down because heat is neither created nor destroyed.
This is the first law of thermodynamics.
Answer:
Homo means same
Hetero means different.
Homogeneous mixtures have one phase, it all looks the same, Fruit juice is homogeneous, solutions are homogeneous.
Heterogeneous mixtures have different phases, you can see the different parts, pepper is an example of a heterogeneous mixture.
- A homogeneous mixture - Think Kool Aid (Completely Dissolved)
- A heterogeneous mixture - Like pepper poured into a glass of milk.
In a homogeneous mixture the constituents are able to dissolve in each other due to their similar intermolecular forces, whereas in a heterogeneous mixture the constituents are not miscible- meaning they can't dissolve in each other.
To clarify: intermolecular forces describe the way that types of molecules will interact with each other. For instance, water (a polar molecule) and naphthalene (a non-polar molecule) are said to be "immiscible" because their intermolecular forces do not match. The saying goes: "like dissolves like". Meaning that molecules that have similar IFs will be mutually soluble (miscible, in other words).
- Homogenous means the same all over...every cubic millimeter is about the same as every other one. Like water or soda.
- Heterogenous means difference in places, like salsa, with slightly different chunks of stuff depending on where you dipped your chip.
