Sulfuric acid undergoes dissociation reaction to produce twice the amount
of hydrogen ions produced by nitric acid in solution.
The volume of sulfuric acid equals; Half the volume of nitric acidReasons:
The concentration of the analytical group = 0.2 M
Volume of reagent = 20 ml
Concentration of the nitric acid to be replaced = 0.1 M
Replacement for the nitric acid = Sulfuric acid
Concentration of the sulfuric acid = Concentration of the nitric acid = 0.1 M
Reaction = Titration
Solution:
Sulfuric acid in solution gives; H₂SO₄ (aq) ⇄ 2H⁺ (aq) + SO₄²⁻(aq)
For nitric acid, we have; HNO₃ (aq) ⇄ H⁺(aq) + NO₃⁻(aq)
Therefore;
1 mole of sulfuric acid gives 2 moles of hydrogen ions
0.1 M solution of sulfuric acid gives 0.2 moles of hydrogen ions per liter
0.1 moles of hydrogen ions are therefore present in half a liter solution of 0.1 M sulfuric acid solution.
However;
0.1 M of nitric acid gives 0.1 moles of hydrogen ions per liter
Therefore;
The volume of sulfuric acid required = Half the volume of nitric acidLearn more about titration and quantitative chemical analysis here:

two samples of solids have similar reactivity with acids and similar densities. their masses and volumes, however, are not at all similar. is it possible that these are the same substance?
Given that the volume and mass of a substance are not defining properties, it is entirely possible for two samples with different volumes and mass to be the same substance.
What are defining properties of a substance?These are properties that can help us to identify a substance. The most useful of which tend to be chemical properties such as reactiveness or melting points. Colors and density can also offer the insight needed to identify elements and substances. Mass and volume are not properties of a substance given that they can change often depending on the sample size and thus do not help to identify a substance.Therefore, since the volume and mass of a substance are not defining properties of a substance, we can confirm that it is entirely possible for two samples with different volumes and mass to be the same substance.

c) A substance has a high melting point and conducts electricity. What type of structure does it have
Answer:
Metallic structure
Explanation:
They have a high melting point due to the strong forces of attraction between the positive ions (cations) and the delocalised electrons. Moreover, they conduct electricity due to the sea of delocalised electrons.
[Extra: It could be an ionic compound since they also have a high melting point, however they only conduct electricity in liquid or aqeouus state.]

Explanation:
Labor unions arose in the nineteenth century as increasing numbers of Americans took jobs in factories, mines, and mills in the growing industrial economy.
The Knights of Labor, founded in 1869, was the first major labor organization in the United States. The Knights organized unskilled and skilled workers, campaigned for an eight hour workday, and aspired to form a cooperative society in which laborers owned the industries in which they worked.
The Knights’ membership collapsed following the 1886 Haymarket Square riot in Chicago. By 1886 the American Federation of Labor (AFL), an alliance of skilled workers’ trade unions, was growing.

The two green substances are not same thing because some of their properties are different and some of them are the same. If they were the same substance, all of their properties would have to be the same.
How could the explanation be improved?
Answer:
Even though the two substances possess many similarities, they have some unique properties. In turn, since they have the same properties, if they were the same substance, it would make matters worse, if the same chemical was in two different places, there would not be a difference between them since they are the same, just as it is with are two different chemicals would have differing properties since they are two properties would vary from one another since they are 2 totally different things!

Answer:
there
Explanation:
organic food is farmed and manufactured per the guidelines put forth by the Department of Agriculture. Organic food is typically pesticide-free, GMO-free, and sustainably farmed.
Non-GMO food, or non-genetically modified food, has not been altered or engineered in any way. Non-GMO food doesn’t necessarily adhere to the same guidelines that organic food does.
GMO food has been genetically modified in some form, usually in a laboratory.

It's called the “The Three Sisters” because it comes from an Iroquois legend. The Legend says corn, beans and squash are inseparable sisters that were given to the people by the “Great Spirit.” It is important to note, however, that the “Three sisters” are also found in many other areas and tribes around North America.

the ____ changes when electrons are gained or lost.
Answer: Matter changes when electrons are gained or lost.
Explanation:
The charge on an atom changes when electrons are gained or lost during chemical changes.
What is an atom?An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether it is solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged particles and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral species and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

How does the equation F= ma tell you that it is easier to push a small chair than a large couch
across the floor?
Explanation:
[tex] \boxed{ \mathsf{F = ma}}[/tex]
The Newton's Second law of motion, also known as The Law of mass and acceleration, derives the given equation in terms of mass, acceleration and force.
It actually states that Force applied on a body is equal to the time rate of change of it's momentum.
Momentum of a body, is the product of it's mass and velocity with which its moving.
This clarifies that objects at rest have zero momentum since they have zero velocity.
If a "source" applies force on an object, it's magnitude would depend on its rate of change of momentum with time.
Since, mass of an object is a fixed entity, so change in momentum would be caused due to change in velocity.
Now, if we happen to have two objects of different mass,
(As, in here, a chair and a large couch) and we have to push them so as to produce the same change in momentum, the force applied on a couch would be more than that applied on the chair.
Answer:This is simply because,
Force = mass × acceleration
If acceleration for both the objects is fixed, the force applied differs due to theur difference in mass.
Note here that Force I'd directly proportional to mass.
The greater the mass is, the higher is the force required to produce same acceleration.
Thus, objects with higher mass will require a greater amount of force to have the same acceleration as the object of light weight.
