Chemistry
1 answer:
Vitek1552 [10]2 years ago
7 0

Answer:

Reactions of Alkenes - Pearson

Explanation:

most Alkenes reaction fall into this large class of electrophilic additions to alkenes.

the pi bond as a nucleophile. A strong electrophile attracts out the electrons out of the pi bond to form a new sigma bond. generating a carbocation

7 H2SO4<br> what is the coefficient?<br> what are the subscript numbers?
baherus [9]

Answer:

Coefficient: number balancing sulfuric acid in a chemical reaction.

Subscripts: number of atoms of each element forming the compound.

Explanation:

Hello!

In this case, since sulfuric acid is a molecule containing hydrogen, sulfur and oxygen in the following way:

- Two hydrogen atoms.

- One sulfur atom.

- Four oxygen atoms.

We can notice the 2 at H represents those two hydrogen atoms, the subscriptless S represent that 1 sulfur atom and the 4 at O represents those four oxygen atoms.

Moreover, since the molecules is given as 7 H2SO4 ; from stoichiometry, we infer that every number preceding the molecule stands for a coefficient which is used to balance a undergoing chemical reaction reaction.

Best regards!

What happens if a acid hits aluminum​
satela [25.4K]

Answer:

Acids that form a complex with aluminum ions can eat their way through the oxide coating, however, so concentrated hydrochloric acid can dissolve aluminum. Zinc is also very reactive and lacks the passivating layer found on aluminum, so it reduces hydrogen ions from acids like hydrochloric acid to form hydrogen gas.

Calculate the solubility of BaCO3 (a) in pure water and (b) in a solution in which [CO32-] = 0.289 M. Solubility in pure water =
jasenka [17]

Answer:

(a). The solubility of BaCO_{3} in pure water is 4.4\times10^{-5}\ M

(b). The solubility of BaCO_{3} in solution is 6.92\times10^{-9}\ M

Explanation:

Given that,

(a). The solubility of BaCO_{3} in pure water

(b). The solubility of BaCO_{3} in a solution

Solubility of CO_{3}^{-2} is 0.289 M

We know that,

The solubility product constant  of  BaCO_{3} is 2\times10^{-9}

Let the solubility of BaCO_{3} is s.

We need to calculate the solubility of BaCO_{3} in pure water

Using formula of solubility

ksp=s\times s

ksp=s^2

s=\sqrt{ksp}

Put the value into the formula

s=\sqrt{2\times10^{-9}}

s=4.4\times10^{-5}\ M

(b). We need to calculate the solubility of BaCO_{3} in solution

Using formula of solubility

ksp=s\times s

Put the value into the formula

2\times10^{-9}=s\times 0.289

s=\dfrac{2\times10^{-9}}{0.289}

s=6.92\times10^{-9}\ M

Hence, (a). The solubility of BaCO_{3} in pure water is 4.4\times10^{-5}\ M

(b). The solubility of BaCO_{3} in solution is 6.92\times10^{-9}\ M
