If equal volumes of the four acids at a concentration of 0.50 M are each titrated with a strong base, which will require the greatest volume of base to reach the equivalence point
Answers
The four acids will require the same volume of the base to reach the equivalence point.
Acid-base titrationStrong acids completely ionize in waters while weak acids are only partially ionized in waters.
At 0.5 M concentration, the hydrogen ion concentrations of all four acids would be the same.
This means that each of the acids will require an equal volume of base concentration in order to get neutralized.

A Grignard synthesis begins with 6.00 g of bromobenzene and ends with 3.94 g benzoic acid. What is the percent yield of the benzoic acid
Answers
The percentage yield of the benzoic acid is mathematically given as
P= 84.56 %
Question Parameters:
A Grignard synthesis begins with 6.00 g
and ends with 3.94 g benzoic acid.
Generally, if 157 g of bromobenzene produced = 122 g of benzoic acid
Hence,6 g of bromobenzene will produce
X== (122 / 157 ) * 6
X= 4.66 g
Since the experimental yield of benzoic acid = 3.94 g
Therefore the Percentage yield
P = 3.94 / 4.66 * 100
P= 84.56 %

Chlorine gas occupies a volume of 1. 2 liters at 720 torr pressure. What volume will it occupy at 1 atm pressure? Note: 760 torr = 1 atm
I NEED HELP!! (mostly w/ torr and atm part)
Answers
Answer:
V2 = 1.14
Explanation:
V1 = 1.2L
P1 = 720 torr (÷ by 760 to get atm. Because 1 atm equal 760 torr) = 0.95 atm
P2 = 1 atm
V2 =?
Follow the equation below to solve this question
P1V1 = P2V2
0.95 x 1.2 = 1 x V2
1.14 = V2
So 1.14 is the answer!
Given that the molar mass of nano3 is 85.00 g/mol, what mass of nano3 is needed to make 4.50 l of a 1.50 m nano3 solution? use molarity equals startfraction moles of solute over liters of solution endfraction.. 6.75 g 18.9 g 255 g 574 g
Answers
574 grams of NaNO₃ is needed to make 4.50 L of a 1.50 M NaNO₃ solution.
How we calculate mass from moles?Mass of any substance will be calculated from moles as:
n = W/M, where
W = required mass
M = molar mass
First we calculate the moles of NaNO₃ from molarity as:
n = M × V, where
M = molarity of NaNO₃ = 1.50 M
V= volume of NaNO₃ = 4.50 L
Moles of NaNO₃ = 1.50 × 4.50 = 6.75 moles
Given molar mass of NaNO₃ = 85 g/mole
Now we calculate all these values on the above equation and calculate the required mass of NaNO₃ as:
W = 6.75 × 85 = 573.75 g or 574 grams
Hence, 574 grams is the required mass of NaNO₃.

first convert grams to moles. 10g Si=.357mol and 60g Cl2 = .846mol
to do this you divide the grams by the given molar mass
second you convert moles of reactants to moles of products. this is done using the mole ratio: 1 mole Si = 1 mole SiCL4 and 2 mol Cl2 = 1 mol SiCl4. The mole ratio can be found in the balanced equation.
.357mol Si = .357 mol SiCl4
.846mol Cl2 = .423 mol SiCl4
Si is the limiting reagent
.357mol SiCl4 = 60.6186g
to get this you multiply the amount of moles by the molar mass
.357mol x 169.8g/mol = 60.6186g

Consider the reaction below. NH4 H2O Right arrow. NH3 H3O Which is an acid-conjugate base pair? NH4 and NH3 NH4 and H3O H2O and NH3 H2O and H3O.
Answers
For the given chemical reaction, NH₄ - NH₃ and H₂O - H₃O is the acid - conjugate base pair.
What is acid - conjugate base pair?An acid - conjugate base pair are those pairs which are differ by the only one proton or H⁺ ion.
Given chemical reaction is:
NH₄ + H₂O → NH₃ + H₃O
According to the Bronsted-Lowry theory, acids are those which gives H⁺ ion and bases are those which accept H⁺ ion in the aqueous solution. In the above reaction NH₄ is an acid as it losses H⁺ ion and NH₃ is the conjugate base of NH₄. Similarly, H₂O is a base as it accepts H⁺ ion and H₃O is the conjugate acid of H₂O.
Hence, NH₄ - NH₃ and H₂O - H₃O is the acid - conjugate base pair.

Answers
Solid have the unique shape and low temperature, plasma have not unique shape and high velocity and both show electrical conductivity.
What is state of matter?Matter is divided into 4 states as solid, liquid, gas and plasma according to the arrangement of atoms present in that.
Solid stateIn the solid state all particles are connected rigidly with each other, and show very less movement that's why maintain a unique structure. They have low temperature as it helps to maintain the rigidity and it also conducts electricity because of the presence of electrons in the constitute atoms.
Plasma stateThis is the 4th state of matter in which positively and negatively charged particles are present, these particles are held together by the weak force that's why they show good velocity, and do not maintain a unique shape. Plasma also shows the electric conductivity.
Hence, both state will conduct electricity and show different characteristics.
