Select ALL of the following statements that are incorrect.
Solids, liquids, and gases are all able to act as solutes in a solution.
Solids, liquids, and gases are all able to act as solvents in a solution.
Solids are not able to act as a solvent if a gas is the solute.
Gases are not able to act as a solvent if a solid is the solute.
Answer:the 4th one is incorrect,and the 1st one is incorrect hope this helps.
Adsorption is defined as a process in which gas molecules tend to adsorb on the surface of a solid solvent.
Therefore, the statement solids are not able to act as a solvent if a gas is the solute, is false.
On the other hand, gases can also act as a solvent if a solid is the solute.
Explanation:
Adsorption is defined as a process in which gas molecules tend to adsorb on the surface of a solid solvent.
Therefore, the statement solids are not able to act as a solvent if a gas is the solute, is false.
On the other hand, gases can also act as a solvent if a solid is the solute.For example, air present in the surrounding acts as a solvent and solid substances present in the surrounding acts as a solute.
Hence, the statement gases are not able to act as a solvent if a solid is the solute, is false.
Thus, we can conclude that following are the statements which are incorrect.
Solids are not able to act as a solvent if a gas is the solute.
Gases are not able to act as a solvent if a solid is the solute.

1. Why is soil erosion relatively less in dense forests as compared to barren, open fields?
Because the deep roots of big trees hold the soil and don't let it slip away simply by rain or wind.
Answer:
the roots of the trees keep the soil in place opposed to a barren landscape that has little to no plants to keep the soil in place

In lab you reacted 60 grams of propane (C3H8) with 13 grams of oxygen gas (O2). Your
reaction made 63 grams of water (H2O). The reaction is shown below:
How much carbon dioxide (CO2) is released into the air?
C3H8 + 5O2 ------> 3CO2 + 4H2O
10 g
73 g
120 g
1368
Answer:
120g
Explanation:
Based on the reaction, when 1 mole of propane and 5 moles of oxygen react, 3 moles of CO2 and 4 moles of H2O are produced. The ratio of production is 3 moles of CO2 per 4 moles of H2O.
Thus, we need to convert mass of water to moles using its molar mass:
Moles H2O (Molar mass: 18g/mol):
63g H2O * (1mol / 18g) = 3.5 moles H2O
Converting to moles of CO2:
3.5 moles H2O * (3 moles CO2 / 4 moles H2O) = 2.625 moles CO2
Mass CO2 (Molar mass: 44g/mol):
2.625 moles CO2 * (44g / mol) = 115.5g of CO2 are released
120gwhich process explains how rock that formed underground is now aboveground in sierra nevada
Answer:
formation process
Explanation:
farllon plate was fully subducted along pacific coast line
The cascade mountains formed from the igneous rocks by plate movement are younger and they are formed by the uplift of plates makes them appears aboveground in sierra Nevada.
What are cascade mountains in Sierra Nevada ?Since they were formed by melting above a subduction zone, the Cascades and Sierra Nevada's rocks are largely igneous. The Cascades, which initially arose 36 million years ago and are still forming now, are younger mountains.
In contrast, the Nevadan Orogeny, which occurred over 200 million years ago, is when the plutonic core of the Sierra Nevada started to form. When subducting at a sharp angle, oceanic lithosphere at the edge of the North American continent melted, and the magma surged back through the continental crust to form a volcanic arc.
The once-deep granite batholith that makes up today's Sierra Nevada was exposed by erosion after being raised by the North American plate. Although one small spur is located in Nevada, the elevated granitic intrusion is 640 kilometers long and largely located in California.

P and Q are two substances such that the melting point of P and the boiling point of Q are the same. If P is a solid at a certain temperature, what state will Q be in at the same temperature?
Answer:
Explanation:
Firstly, it should be noted that melting and freezing points are the same. Thus, when a substance melts at a certain temperature, it means it can also start freezing/solidifying at that same temperature. That been said, when the substance P is a solid at a certain temperature, the other compound Q will boil at that same temperature and hence will be a gas at that same temperature.
If P is solid, it simply means that Q must still be in the liquid state.
From the question, we can see that, the melting point of P and the boiling point of Q are the same. The melting point of a substance is the temperature at which the solid turns to liquid while the boiling point of a substance is the temperature at which a liquid turns to a gas.
If P is solid, it simply means that Q must still be in the liquid state. It has not yet started boiling since the melting point of P and the boiling point of Q are the same.

At the Beltway Outlet store, you buy x computer games for 13$ each and a magazine for 4$. Write an expression in simplest form that represents the total amount of money you spend. Someone please help
Answer:
y = 13x + 4
Explanation:
Given parameters:
number of computer games bought = x
cost of each games = $13
number of a magazine = 1
cost of magazine = $4
Unknown:
Total amount of money spent = ?
Solution:
The total amount spent;
let total amount = y
y = total cost of magazine + total cost of computer games
total cost of magazine =$4
total cost of computer games = 13x
y = 13x + 4
If the momentum of a car is reduced by half, assuming mass did not change, what must also have been reduced by half?
Answer:
Velocity is halved
Explanation:
Momentum is contingent on mass and velocity. The quantity of motion in a body is called the momentum of the body.
Momentum = mass x velocity
Now, if mass does not change and momentum is reduced by half, it suggests that the velocity was reduced by half.
Velocity is directly related to momentum.
