Answer:
NaNO3
Explanation:
Hello,
In this case, the required reaction is an acid-base neutralization reaction which is said to be:
[tex]HNO_3+NaOH\rightarrow NaNO_3+H_2O[/tex]
There, we see that the sodium displaced the hydrogen in the nitric acid to form sodium nitrate a very used salt in the industry, so, as a result of that displacement, water is formed as the secondary neutralization product. For the above mentioned, answer is NaNO3 .
Best regards.
Answer: NaNO3
Explanation:
A salt sodium nitrate (NaNO3) is formed alongside water (H2O) when HNO3 and a solution of NaOH undergoes a neutralization reaction.
HNO3 + NaOH --------> NaNO3 + H2O
A 350. mL air sample collected at 35 degrees C has a pressure of 556 mm Hg.
What pressure will the air exert if it is allowed to expand to 425 mL at 57 degrees
C? Show your work in the space below.
Answer:
485 torr
Explanation:
Explanation:
We can solve this equation using the combined gas law:
P1V1/T1=P2V2/T2
Remember, always use the absolute (Kelvin) temperature when working with gas equations.
The temperature conversions are
T1=C+273=35o+273=308K
T2=57C+273=330K
Since we're trying to find the final pressure, let's rearrange this equation to solve for
P2:
P2=P1V1T2/T1V2
Our known values:
P1= 550 torr
V1=350mL
T1=308K
V2=425"mL
T2=330K
Let's plug these into the equation to find the final pressure:
The final pressure after it is subjected to these changes is thus 485torr

What type of bond is formed during dehydration synthesis?
O A
carbon bonds between amino acids
B.
carbon bonds between carbohydrates
C. hydrogen bonds between lipids
O D. peptide bonds between amino acids
A carbon bond between the amino acids is formed in a dehydration reaction. So the correct option is A.
What is a dehydration reaction?
A reaction where two smaller molecules are combined in a chemical manner by the removal of an element from each of these molecules is called a dehydration reaction. Organic compounds are classified on the basis of structure. They are classified as aliphatic and aromatic compounds. Different kinds of chemical reactions are involved in the formation of new compounds when there is a change in bonding between the atoms.
There are some chemical reactions that form a molecule and some only show a displacement or substitution of atoms. There are synthesis or combination reactions that involve a combination of two substances to form one molecule.
On the other hand, there are decomposition reactions in which one substance decomposes to form more than one substance. There are displacement reactions which can be single or double displacement. They involve the displacement of one or more components of compounds among each other. Addition, substitution, rearrangement, elimination, and oxidation-reduction reactions are some of the common organic reactions.
Therefore, the correct option is A.

A student determines that she used 0.0665 mol of sodium hydroxide (NaOH) to completely titrate 25.00 mL of sulfuric acid solution (H2SO4). What is the molarity of the sulfuric acid?
0.00131 M
0.00262 M
1.31 M
2.62 M
A student determines that she used 0.0665 mole of sodium hydroxide (NaOH) to completely titrate 25.00 mL of sulfuric acid solution. The molarity of the sulfuric acid is 1.31 M. Therefore, option C is correct.
What is molarity?Number of moles of solute per liter of solution is known as molarity.
The balanced chemical equation for the reaction between sodium hydroxide and sulfuric acid is:
2 NaOH + H₂SO₄ → Na₂SO₄ + 2 H₂O
According to the balanced equation, one mole of sulfuric acid reacts with two moles of sodium hydroxide. Therefore, the number of moles of sulfuric acid in the titrated solution can be calculated as:
moles of H₂SO₄ = (moles of NaOH) / 2
moles of H₂SO₄ = 0.0665 mol / 2
moles of H₂SO₄ = 0.03325 mol
The volume of the sulfuric acid solution used in the titration is 25.00 mL, which is equivalent to 0.02500 L. The molarity (M) of the sulfuric acid can be calculated as:
Molarity of H₂SO₄ = moles of H₂SO₄ / volume of H₂SO₄ solution in liters
= 0.03325 mole / 0.02500 L
= 1.31 M
Thus, option C is correct.

can somebody help me name these organic compound plz
Answer:
A. 3–Ethyl–2–methylpentane.
B. 3–Ethyl–1,5,5–trimethylcyclohexene.
Explanation:
To name the compound, we must observe the following:
1. Locate the longest continuous carbon chain. This gives the parent name.
2. Identify the substituent groups attached.
3. Locate the position of the substituent groups by giving them the lowest possible low count alphabetically.
4. Combine the above to name the compound.
Now let us name the above compounds
For compound (A)
1.The longest chain is carbon 5 i.e pentane.
2. The substitute attached are:
Ethyl => CH2CH3
Methyl => CH3
3. Ethyl comes before methyl alphabetically. But considering the structure of the compound, ethyl assume same position from either side of the compound. Therefore, we'll consider the lowest possible count for methyl. Therefore, their position is given below:
Ethyl => CH2CH3 => carbon 3.
Methyl => CH3 => carbon 2.
4. The name of the compound is:
3–Ethyl–2–methylpentane.
Compound B.
This is a cyclic structure.
1. The parent name is cyclohexene.
2. The substitute groups attached are:
Ethyl => CH2CH3
Methyl => CH3
3. Since the compound is unsaturated, the functional group is the double bond. Hence, we shall start our counting from the double bond and also considering alphabetical order of the substituent.
Please note methyl (CH3) appears three times.
Ethyl => CH2CH3 => carbon 3
Methyl => CH3 => carbon 1, 5 and 5.
4. The name of the compound is:
3–Ethyl–1,5,5–trimethylcyclohexene
A fox spots a rabbit in a field. The fox begins to chase the rabbit, and the rabbit runs away. Which statement best describes the rabbit's behavior in response to the stimulus of being chased?
Select one:
The rabbit's behavior is a response caused by an internal stimulus.
The rabbit's behavior is a tropism.
The rabbit's behavior is a fight-or-flight response.
The rabbit's behavior is a response caused by hunger.
Answer:
C. The rabbit's behavior is a fight-or-flight response
Explanation:
The rabbit has a fight or flight response which means that when there is danger, the rabbit will either fight it or run away. In this case it ran away
The response of the rabbit in response to the fox chasing has been the fight and flight response. Thus, option C is correct.
What is a stimulus?A stimulus can be given as the physical or the chemical messenger that mediates the formation of the functional change in the body. The reaction to the stimulus has been the spontaneous reaction that can form the sudden response forming reaction.
The fox chasing the rabbit has been mediating the formation of the stimulus. The chasing act as the stimulus to the rabbit forming the rabbit to create the response or reaction of running. The reaction that forms with the stimulus of fear and frightening has been the fight and flight response.
The stimulus that has been formed arouses the fear of getting caught and works as the fight and flight response. Thus, option C is correct.

Explain the different principles that allow roller coasters to rip and roar around the tracks. In your response, include how energy is transferred back and forth between kinetic and potential.
Answer:
In the roller coasters the potential energy that is given is the gravitational potential energy, which this energy increases its value as the object moves away from the earth, that is to say, the more height the roller coaster acquires the more gravitational potential energy it will have, and Said train where people usually get on the roller coaster will descend or descend with greater acceleration.
This gravitational potential energy once the mountain begins to descend or descend is converted into kinetic energy
Explanation:
This that we wrote above is considering that the roller coaster does not have curved routes but rectilinear, in the case that it had curved routes, a force would be added in addition to those written that is the centripetal force, it is the same force that appears in the centrifuges or dryers of clothes or the same washing machine. This force, the centripetal force is the force that draws a moving object, in a curvilinear path, towards the center of the curvature.
To measure the volume of a washing machine, use:
liters
kiloliters
kilograms
tons
Answer:
kg
Explanation:
Answer:
You should use tons or kilograms because a washing machine is very heavy.
