Answer:

In our Sun, as in other stars, roughly 99.9% or so of all light emitted is emitted in a thin layer known as the photosphere, or light sphere. This is explained as follows. Interior to the photosphere the gas is ever denser and becomes far too opaque for any photon to emerge directly from that layer.

The ionization energies of Calcium are (in KJ/mol): 1st: 589.8 2nd: 1145.4 3rd: 4912.4
defon

Answer:

See whole explanation to understand

Explanation:

the reason why there is such a large jump from 2nd to 3rd ionization energy for calcium is because to remove the third electron, a larger amount of energy is required, since the shell is closer to the nucleus, and higher attraction exists between them. This is why the second ionization energy is 1125.4 and then the third IE is 4912.4 which is a very big difference. It's all about the elections and energy!!

A mole of ethyl alcohol weighs 46 g. how many grams of ethyl alcohol are needed to produce 1 l of a 2-millimolar (2 mm) solution
Thepotemich [5.8K]
Answer: 92mg of ethyl alcohol 

2 milli molar of ethyl alcohol means 2 milli mole glucose for 1 liter of water. Since we want to make 1L of solution, then the amount of ethyl alcohol needed is: 2 milli mole/l x 1l= = 2 x 10^-3 mole

Ethyl alcohol molecular weight is 46g/mole, then 2 mili mole of glucose is= 2x 10^-3 mole x 46 grams/mole= 92 grams x 10^-3= 92mg

How many moles of water are produced from 19.2 g of B2H6
lbvjy [14]
The Balanced chemical equation of reaction of Borane with oxygen is as follow,
                                  B₂H₆ + 3O₂ -----> 2HBO₂ + 2H₂O
According to this equation 27.66 g (1 mole) of B₂H₆ reacts with oxygen to produce 36 g (2 moles) of water.
The amount of water produced when 19.2 g of B₂H₆ reacted is calculated as follow,
\frac{27.66 g B2H6 produced}{19.2 g of B2H6 will produce} = \frac{36 g of H2O}{x g of water}
Solving for x,                       
              x = (36 g of H₂O ₓ 19.2 g of H₂B₆) / 27.66 g of B₂H₆

              x = 24.98 g of H₂O

Result:
           24.98 g 
of water is produced when 19.2 g of B₂H₆ is reacted with excess of oxygen.

If you want to lift a 30-kg box to a height of 1 m, how much work will it take?
natta225 [31]

Explanation:

workdone = force x distance

force = mass x acceleration

30 x 10 = 300N

300N x 1m

workdone= 300J
