g 10.00 mL of phosphoric acid (H3PO4) are titrated with 0.1000 M sodium hydroxide. 15.00 mL of the sodium hydroxide solution are
aliya0001 [1]

<u>Answer:</u> The molarity of phosphoric acid is 0.05 M

<u>Explanation:</u>

A neutralization reaction is defined as the reaction in which an acid reacts with a base to form a salt and water molecule.

At equivalence, moles of acid becomes equal to the moles of base. The equation for the neutralization follows:

n_1M_1V_1=n_2M_2V_2              ........(1)

where,

n_1, M_1\text{ and }V_1 are the n-factor, molarity and volume of acid that is H_3PO_4

n_2, M_2\text{ and }V_2 are the n-factor, molarity and volume of the base that is NaOH

Given values:

n_1=3\\M_1=?M\\V_1=10.00mL\\n_2=1\\M_2=0.1000M\\V_2=15.00mL

Plugging values in equation 1:

3\times M_1\times 10.00=1\times 0.1000\times 15.00\\\\M_1=\frac{1\times 0.1000\times 15.00}{3\times 10.00}\\\\M_1=0.05M

Hence, the molarity of phosphoric acid is 0.05 M

How can Newton's Third Law of Motion be used to explain why it is difficult to walk on a slippery surface, such as ice?
Olenka [21]
E ground pushes you forward. But that interaction is friction. Reduce friction and it doesn't matter how strong your legs are, the surface is incapable of pushing you accordingly. The coefficient of static friction is very low so it is easy to slide your foot rather than push.

7. One mole of phosphorous pentachloride contains how many of each of the following:
RideAnS [48]

Answer:

a) 6.02 × 10^23

b)6.02×10^23

c)3.01×10^24

d) 3.612×10^24

In every mole of a substance there are 6.02×10^23 entities.

in ( c) there are 5 carbon atoms . 5 is multiplied by the number of moles of the molecule and then multiplied by 6.02×10^23. ( using the formula N=nL )

____________ alcohols are alcohols having the general structure R₃COH. ____________ (or oxiranes) are cyclic ethers having the o
horsena [70]

Answer: Tertiary alcohol.

Epoxide,

phenols,

Ethers have two alkyl groups bonded to oxygen atoms

Enols

primary alcohols,

alcohols

Explanation:Tertiary alcohol are alcohols having the general structure R₃COH. Epoxide are cyclic ether with a three-membered ring. The basic structure of an epoxide contains an oxygen atom attached to two adjacent carbon atoms of a hydrocarbon. Phenol is an aromatic organic compound with the molecular formula C₆H₅OH. An alcohol contains a hydroxy group (OH group) bonded to an sp3 hybridized carbon atom. Enols are a type of reactive structure or intermediate in organic chemistry that is represented as an alkene with a hydroxyl group attached to one end of the alkene double bond. Alcohols are classified like halides and hydrogens; primary (1°), secondary (2°), or tertiary (3°) depending on the number of carbons bonded to the carbon with the halogen.
