The temperature of a star is 6000K and its luminosity is 1000. Which type of star is it?

Lorico [155]

Answer:

Its probably none of those.

Explanation:

White dwarf temperatures can exceed 100,000 Kelvin according to NASA (that's about 179,500 degrees Fahrenheit). Despite these sweltering temperatures, white dwarfs have a low luminosity as they're so small in size according to NMSU.

A reaction of 41.9 g of Na and 30.3 g of Br2 yields 36.4 g of NaBr . What is the percent yield?

Licemer1 [7]

Answer: The percent yield is, 93.4%

Explanation:

First we have to calculate the moles of Na.

$\text{Moles of Na}=\frac{\text{Mass of Na}}{\text{Molar mass of Na}}=\frac{41.9g}{23g/mole}=1.82moles$

Now we have to calculate the moles of $Br_2$

${\text{Moles of}Br_2} = \frac{\text{Mass of }Br_2 }{\text{Molar mass of} Br_2} =\frac{30.3g}{160g/mole}=0.189moles$

${\text{Moles of } NaBr} = \frac{\text{Mass of } NaBr }{\text{Molar mass of } NaBr} =\frac{36.4g}{103g/mole}=0.353moles$

The balanced chemical reaction is,

$2Na(s)+Br_2(g)\rightarrow 2NaBr$

As, 1 mole of bromine react with = 2 moles of Sodium

So, 0.189 moles of bromine react with = $\frac{2}{1}\times 0.189=0.378$ moles of Sodium

Thus bromine is the limiting reagent as it limits the formation of product and Na is the excess reagent.

As, 1 mole of bromine give = 2 moles of Sodium bromide

So, 0.189 moles of bromine give = $\frac{2}{1}\times 0.189=0.378$ moles of Sodium bromide

Now we have to calculate the percent yield of reaction

$\%\text{ yield}=\frac{\text{Actual yield}}{\text{Theoretical yield}}\times 100=\frac{0.353 mol}{0.378}\times 100=93.4\%$

Therefore, the percent yield is, 93.4%

The thing that the discovered is a "partially molten state"<br> What would that be considered as

castortr0y [4]

Answer:

liquid and solid

Explanation:

Research scientists of scotland discovered a new state of the matter which consists of both liquid and solid. Scientifically there are three states of matter i.e Solid, Liquid and Gas, but now there are chances of one more state of matter which which consists of more than one state of the existing three states of the matter which have both liquid and solid state.

This discovery took place with the help of artificial intelligence of today's world which is transforming the world day by day.

The State is considered to be true as it is thermodynamically stable state of the matter.

Two aqueous solutions are prepared: 1.00 m Na2CO3 and 1.00 m LiCl. Which of the following statements is true?

svlad2 [7]

Answer:

The $Na_{2}CO_{3}$ solution has a higher osmotic pressure and higher boiling point than LiCl solution.

Explanation:

As concentrations of two aqueous solutions are same therefore we can write:

$\Delta P\propto i$ , $\Delta T_{b}\propto i$ and $\pi \propto i$

where $\Delta P$ , $\Delta T_{b}$ and $\pi$ are lowering of vapor pressure, elevation in boiling point and osmotic pressure of solution respectively. $i$ is van't hoff factor.

$i$ = total number of ions generated from dissolution of one molecule of a substance (for strong electrolyte).

Here both $Na_{2}CO_{3}$ and LiCl are strong electrolytes.

So, $i(Na_{2}CO_{3})=3$ and $i(LiCl)=2$

Hence, lowering of vapor pressure, elevation in boiling point and osmotic pressure will be higher for $Na_{2}CO_{3}$ solution.

Therefore the $Na_{2}CO_{3}$ solution has a higher osmotic pressure and higher boiling point than LiCl solution.
