There are 0. 650 moles of sodium bromide can be produced from the reaction of 1. 03 moles of bromine gas with 0. 650 moles of sodium .
Calculation ,
To find the number of moles of sodium bromide we have to write balanced chemical equation first .
[tex]2Na (s)+ Br_{2}(g)[/tex] → 2NaBr (s)
from the equation we can conclude that 2 moles sodium react with one mole of bromine to form 2 mole of sodium bromide .
But 1. 03 moles of bromine gas ( that is equal to the number of moles required in the equation) with 0. 650 moles of sodium ( that is half of required mole ) is given .
So, sodium is present as limiting reactant .
So , the number of sodium bromide formed is equal to the number of moles of sodium atom.
Hence , the number of sodium bromide formed = 0. 650 moles

What is ideal gas?Ideal gas is a hypothetical gas whose molecules occupy negligible space and have no interactions, and which consequently obeys the gas laws exactly.
In the limit of low pressures and high temperatures, where the molecules of the gas move almost independently of one another, all gases obey an equation of state known as the ideal gas law:
PV = nRT,
P is pressure of gas (atm)T is temperature of gas (K)where n is the number of moles of the gas R is the universal gas constant, 8.3145 joules/K.When Temperature is constant so, it follow Boyle's law:
P1 V1 = P2 V2
P1 = 8.34atm, V1 = 10.28 L, P2 = 6.98atm
V2 = P1 V1 / P2
V2 = 8.34atm x 10.28 / 6.98atm

The "break-even" interest rate for year n that equates the return on an n-period zero-coupon bond to that of an n - 1 - period zero-coupon bond rolled over into a one-year bond in year n is defined as:_________
The "break-even" interest rate for year n that equates the return on an n-period zero-coupon bond to that of an n - 1 - period zero-coupon bond rolled over into a one-year bond in year n is defined as the forward rate.
A forward rate is a specified price agreed by all parties involved for the delivery of a good at a specific date in the future. The use of forward rates can be speculative if a buyer believes the future price of a good will be greater than the current forward rate. Alternatively, sellers use forward rates to mitigate the risk that the future price of a good materially decreases.
Regardless of the prevailing spot rate at the time the forward rate meets maturity, the agreed-upon contract is executed at the forward rate. For example, on January 1st, the spot rate of a case of iceberg lettuce is $50. The restaurant and the farmer agree to the delivery of 100 cases of iceberg lettuce on July 1st at a forward rate of $55 per case. On July 1st, even if the price per case has decreased to $45/case or increased to $65/case, the contract will proceed at $55/case.

A solution with a ph of 6 has ________ times as many hydrogen ions as a solution with a ph of 8.
Answer:
A solution with a ph of 6 has 100 times as many hydrogen ions as a solution with a ph of 8.
Explanation:
At 7 on the pH scale, a solution is neutral. Any pH lower than 7 is acidic and any pH above 7 is basic.
Acidity is a measure of the concentration of hydrogen ions in a solution. The more acidic a solution, the more hydrogen ions it has. Therefore, if the pH is decreasing, the hydrogen ion concentration is increasing.
The pH scale increases by a factor of 10. This means that for every one unit change, the hydrogen ion concentration changes tenfold. Therefore, if the pH is decreasing by 2 units (from pH 8 to pH 6), the hydrogen ion concentration should increase 100-fold (10 x 10 = 100).

A molecular size affects the rate of evaporation when the larger the intermolecular forces in a compound, the slower the evaporation rate and this correlates with temperature change.
Molecular size seems to have an effect on evaporation rates in that the larger a molecule gets or grows from a base chemical formula, its evaporation rate will get slower.
What is the molecular size?This is a measure of the area a molecule occupies in three-dimensional space as this relates to the physical size of an individual molecule.

Pair of LiI and Ca(NO3)2 is soluble in water.
Here LiI stands for lithium iodide and Ca(NO3)2 stands for Calcium Nitrate.
Water's polarity, which is the unequal sharing of electrons among its atoms, is what allows it to be such a great solvent. Typically, water is held together through this polarity of partial positive and negative charges. Positive is attracted to negative, making a cohesive structure. When polar compounds or ions are added to water, they break up into smaller components, or dissolve, to become part of the solution. The water's partial charges attract different parts of the compound, making them soluble in water.
Polar Molecules
Similar to ions, polar molecules are able to dissolve in water. Like water, polar molecules have partial positive and negative charges. The attraction between opposite partial charges helps polar molecules dissolve in water.
Water doesn't have a full positive or negative charge; instead, it possesses a partial positive and partial negative charge. This is because oxygen is a lot more electronegative than hydrogen. This means that oxygen draws more electrons to it than the hydrogen does. Since more electrons are moving towards the oxygen, it has a slightly higher negative charge than water's hydrogen atoms.
Let's look at another simple example: a carbon-fluorine bond. Since fluorine is more electronegative than carbon, it draws more electrons over to it, making it partially negative.

What atomic or hybrid orbitals make up the sigma bond between c2 and h in ethylene, ch2ch2?
Explanation:
According to orbital hybridization theory, in ethene the C atoms are using sp2 hybrid orbitals. This leaves one unhybridized p orbital available to form the second bond (Pi bond) in the C-C double bonds.
One sp2 hybrid orbital from each C atom overlap to form one sigma bond between the two carbon atoms. One p orbital from each C atom then overlap to form a pi bond that completes the C-C double bond. The H atoms are bonded via sigma bonds to the C atoms when the H s orbitals overlap with the remaining sp2 hybrid orbitals from each C.

1. reacting a mixture of ketone and alcohol with an organometallic compound M(X)n to form compound HX, wherein M is chosen from aluminium, titanium and boron, where n is the valance of a M, X denotes equal or different organic group chosen from alkyl group and electric group having up to 10 carbon atom
2. liberating the newly formed compound HS from the reaction mixture by distillation
3. separating the ketone from the organometallic compound formed by reaction between M(X)n and the alcohol in the mixture.
Thus, we concluded that above compound is seprated by forming organometallic compound.
