Describe the preparation<br>of 2.00h of o.108m Bach<br>from Bad. 28 (244-3 g/mal)​
snow_tiger [21]

The question is incomplete, the complete question is; Describe the preparation of 2.00 L of 0.108 M BaCl2 from BaCl2.2H2O

Answer:

See explanation

Explanation:

First we must know the molar mass of the compound = 244.3 g/mol

Now we must calculate the number of moles of BaCl2.2H2O in the solution.

number of moles = concentration * volume = 0.108 M * 2.00 L = 0.216 moles

Now the mass of solid that we need to take can be obtained from;

number of moles = mass/molar mass

mass = number of moles * molar mass

mass = 0.216 moles * 244.3 g/mol

Mass = 52.8 g

Hence, we must weigh 52.8 g of BaCl2.2H2O accurately in a balance and dissolve it in 2 L of water to give 0.108 M solution of BaCl2.2H2O.

Reaction intermediates differ from activated complexes in that A. they are stable molecules with normal bonds and are frequently
vova2212 [387]

Answer:

they are molecules with normal bonds rather than partial bonds and can occasionally be isolated.

Explanation:

In chemistry, reaction intermediates are species that are formed from reactants and are subsequently being transformed into products as the reaction progresses. In other words,  reaction intermediates are species that do not appear in a balanced reaction equation but occur somewhere along the reaction mechanism of a non-elementary reaction. They are usually short lived species that possess a high amount of energy. They may or may not be isolated.

They are often molecular species with normal bonds unlike activated complexes that are sometimes hypervalent species.

Is precipitate in water an electrolyte solution
vagabundo [1.1K]
When no ions are produced, or the ion content is low, the solute is a non-electrolyte. Non-electrolytes do not conduct electricity or conduct it to a very small degree. In an aqueous solution a strong electrolyte is considered to be completely ionized, or dissociated, in water, meaning it is soluble

Two objects of equal mass have a force of gravity of 6 N between them. Imagine the mass of one is cut in half and the other stay
Alenkasestr [34]

Answer:

F' = 3 N

Explanation:

Given that,

Two objects of equal mass have a force of gravity of 6 N between them.

If the mass of one is cut in half and the other stays the same such that,

m₁' = m₁ and m₂' = (m₂/2)

We need to find the new force. The gravitational force between two objects is given by :

F=G\dfrac{m_1m_2}{r^2}

We have, F = 6 N

New force,

F'=G\dfrac{m_1'm_2'}{r^2}\\\\F'=\dfrac{Gm_1\times \dfrac{m_1}{2}}{r^2}\\\\=\dfrac{1}{2}\times \dfrac{Gm_1m_2}{r^2}\\\\F'=\dfrac{F}{2}\\\\F'=\dfrac{6}{2}\\\\F'=3\ N

So, the new force becomes 3 N.
