A gas has a volume of 275 mL and a pressure of 3 atm. What is the new volume if the pressure decreases to 1.8 atm?
Answer:
Use Boyles law.
Given:
P1=3atm
V1=275mL
P2=1.8atm
V2=?
P1V1=P2V2
3x275=1.8xV2
V2=3x275/1.8
V2=458.3mL
Nung 20 g CaCO3 và hấp thụ hoàn toàn khí CO2 sinh ra vào 0,5 lit dung dịch NaOH 0,56 M .Tính nồng độ mol của muối thu được
Answer:
nCaCO3 = 20/100 = 0,2 mol
CaCO3 --> CaO + CO2
0,2 ----------------> 0,2
nNaOH = 0,5.0,56 = 0,28 mol
=> T = nNaOH/nCO2 = 0,28/0,2 = 1,4
=> sản phẩm tạo ra bao gồm : Na2CO3 và NaHCO3
NaOH + CO2 --> NaHCO3
x -------> x --------> x
2NaOH + CO2 --> Na2CO3 + H2O
y ---------> 1/2y ---> 1/2y
ta có : nCO2 = nMuối = 0,2 mol
=> CmMuối = 0,2/0,5 = 0,4 M
what is the molarity of an hcl solution if 50.0 ml is neutralized in a titration by 40.0 ml of 0.400 m naoh? group of answer choices 0.200 m 0.280 m 0.320 m 0.500 m
The molarity of an HCl solution if 50.0 ml is neutralized in a titration by 40.0 ml of 0.400M NaOH is 0.320 M.
HOW TO CALCULATE MOLARITY:
The Molarity of an acid when involved in a titration procedure can be calculated by using the formula below:M1V1 = M2V2
Where;
M1 = molarity of acid (M)M2 = molarity of base (M)V1 = volume of acid (mL)V2 = volume of base (mL)According to this question,
M1 = ?M2 = 0.400MV1 = 50 mLV2 = 40 mLM1 × 50 = 0.400 × 40
50M1 = 16
M1 = 16 ÷ 50
M1 = 0.32M
Therefore, the molarity of an HCl solution if 50.0 ml is neutralized in a titration by 40.0 ml of 0.400M NaOH is 0.32 M.Learn more at: https://brainly.com/question/8732513?referrer=searchResults

what is formed when the number of electrons is changed?
Answer:
Explanation:
Whether the electrons are added or given away makes no difference to the name given to parent atom -- It is called an ion which means that it has a charge. The word atom is reserved for something on the periodic table that has no charge.
Answer: Chemical bond formed when one or more electrons are transferred from one atom to another.

when is it appropriate to form double or triple bonds in a lewis structure?
It is appropriate to form double or triple bonds in a Lewis structure when four or six electrons are shared.
A Lewis structure is a representation of a molecule using dots to show the valence electrons in the molecule. This dots are shown around the symbols of the elements.
However, in instances where four or six electrons are shared between bonding atoms, a double or triple bond is used. A double bond means that four electrons are shared. A triple bond means that six electrons are shared.

What is the law of conservation of mass and how does it relate to chemical equations?
What does it mean for a
chemical equation to be balanced?
Answer: Matter cannot be created or destroyed in chemical reactions.
Explanation: This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.
Metals are good conductors of current.

If 83.6 grams of H2 and 257 grams of N2 react, how many grams of ammonia will be produced?
The mass of ammonia that would be produced is 312.5 g
First, we will write a balanced chemical equation for the reaction
The balanced chemical equation for the reaction is
3H₂(g) + N₂(g) → 2NH₃(g)
This means
3 moles of hydrogen gas reacts with 1 mole of nitrogen gas to produce 2 moles of ammonia.
First, we will determine the number of moles of each reactant present
For Hydrogen (H₂)
Mass = 83.6 g
Molar mass = 2.016 g/mol
Using the formula
[tex]Number\ of\ moles = \frac{Mass}{Molar\ mass}[/tex]
Number of moles of H₂ present = [tex]\frac{83.6}{2.016}[/tex]
∴ Number of moles of H₂ present = 41.468254 moles
For Nitrogen (N₂)
Mass = 257 grams
Molar mass = 28.0134 g/mol
∴ Number of moles of N₂ present = [tex]\frac{257}{28.0134}[/tex]
Number of moles of N₂ present = 9.174181 moles
Since,
3 moles of hydrogen gas reacts with 1 mole of nitrogen gas to produce 2 moles of ammonia
Then,
27.522543 moles of hydrogen gas will react with the 9.174181 moles of nitrogen gas to produce 18.348362 moles of ammonia
∴ 18.348362 moles of ammonia will be produced during the reaction
Now, for the mass of ammonia that would be produced
From the formula
Mass = Number of moles × Molar mass
Molar mass of ammonia = 17.031 g/mol
Mass of ammonia that would be produced = 18.348362 × 17.031
Mass of ammonia that would be produced = 312.49095 g
Mass of ammonia that would be produced ≅ 312.5 g
Hence, the mass of ammonia that would be produced is 312.5 g

Which immunization is available to prevent communicable disease and illness?WILL MARK BRAINLIEST 30 PTS
bronchitis
diabetes
measles
strep throat
Measles is a communicable disease that requires immunization to prevent illness when exposed to it.
Measles is a communicable disease and highly contagious. It is usually very serious in children. The disease can be contacted through droplets in the air, physical contact and through mother-to-child transmission.
It is a very serious disease as it is caused by a virus which replicates very fast in the throat and nose thereby creating symptoms such as runny nose, coughing, sneezing and is usually accompanied with a rash.
The severity and death rates is what gave rise to the creating of a measles vaccine which is usually given to babies after birth to make them immune to the potential exposure to the virus.
Diabetes, bronchitis and strep throat have no vaccine as they can always be treated or managed with over-the-counter drugs.

Bernice created a table using her knowledge of charged and uncharged objects. Which statement best explains why the table is incorrect?
Charged Object Uncharged Object
Negatively charged attract
Positively charged repel
The negatively charged and uncharged objects do not attract.
A positively charged object attracts an uncharged object.
Both positive and negative charges repel uncharged objects.
An uncharged object neither attracts nor repels charged objects.
Answer:B
Explanation:
A positively charged object attracts an uncharged object.
A positively charged object attracts an uncharged object statement is in correct in the table. Hence option B is correct.
What are charge?Charge are defined as a subatomic particle's ability to experience force when exposed to an electric and magnetic field. The value that the atom reaches after removing or gaining electrons is known as charge. Only ions that comply with the octat rule are stable. Atoms or groups of atoms with an electric charge are referred to as ions. Cations are positive-charged ion particles. Anions are ion types that have a net negative charge.
A charged object will cause an opposing charge to be applied to an uncharged object when it is brought close to the charged one. These two things are drawn to one another because opposing charges attract one another. Other charged items are drawn to a charged object whereas uncharged objects are repelled by it.
Thus, a positively charged object attracts an uncharged object statement is in correct in the table. Hence option B is correct.
