Answer:
I think its C. It turns the Gulf Stream northeast and the Brazil Current southwest.
All of the planets orbit around the sun, due to the gravitational pull of the sun
Answer:
Among the given options which one best suits the definition of an element?
Explanation:
Element:
Element is the pure form of matter which cannot be broken down into new simpler substances either by physical or chemical means.
It is made up of the same type of atoms.
For example:
Copper, silver, gold, oxygen, etc.
Among the given options:
the third option that is elements are made of atoms is the correct option.
Remaining statements:
Elements are made up of complex chains of carbon and oxygen is wrong,
Elements can be broken down into other simpler substances is wrong.
Because we don't get any simpler substances from elements.
For example, if we break a gold rod many times also only its size varies and no new substance is obtained from it.
All elements have the same chemical properties is a wrong statement.
Because each element is unique and it has its own properties.
Your balanced equation for this reaction is:
HCOOH (aq) + H2O (aq) → HCOO- (aq) + H3O+ (aq)
So from the reaction, we can see when formic acid dissolved in water so H3O+ ions will be formed.
and we can see that it is a balanced equation as:
we have H atoms = 4 on both sides of the reaction
and C atoms = 1 atom on both sides of the reaction
and O atoms = 3 atoms on both sides of the reaction
So it is our final balanced equation of the reaction.
Answer:
The large relative distances between particles in a gas means that there is considerable empty space between the particles.
The assumption that particles in a gas are relatively far apart explains gas compressibility.
Compressibility is a measure of how much the volume of matter decreases under pressure.
Energy is released by a gas when it is compressed
Explanation:
The kinetic molecular theory establishes that gases are composed of molecules. These molecules of gas are far apart from each other hence there is a considerable empty space between the gas molecules. As a result of these empty spaces between gas molecules, it is possible to compress a gas.
Compressibility is defined as a measure of how much the volume of matter decreases under pressure. When a gas is compressed, work is done on the gas and energy is evolved hence the gas heats up.
