The element is Magnesium

It has total 12 electrons

it has electronic configuration

$\\ \sf\longmapsto 2,8,2$

$\\ \sf\longmapsto 1s^22s^22p^63s^2$

In valence cell it has 2 electrons and therefore its valency is 2

If a Ferrari with an initial velocity of 10m/s accelerates at a rate of 5m/s2 for 3 seconds. What will it’s final velocity be?

Reika [66]

Answer:

V = 25 m/s

Explanation:

From first equation of motion, V = U + at

V = 10 + ( 5×3 )

V = 25 m/s

What is the solubility of ethylene (in units of grams per liter) in water at 25 °C, when the C2H4 gas over the solution has a pa

vredina [299]

Answer: The solubility of ethylene gas in water is $9.16\times 10^{-2}g/L$

Explanation:

To calculate the molar solubility, we use the equation given by Henry's law, which is:

$C_{C_2H_4}=K_H\times p_{C_2H_4}$

where,

$K_H$ = Henry's constant = $4.78\times 10^{-3}mol/L.atm$

$C_{C_2H_4}$ = molar solubility of ethylene gas = ?

$p_{C_2H_4}$ = partial pressure of ethylene gas = 0.684 atm

Putting values in above equation, we get:

$C_{C_2H_4}=4.78\times 10^{-3}mol/L.atm\times 0.684atm\\\\C_{C_2H_4}=3.27\times 10^{-3}mol/L$

Converting this into grams per liter, by multiplying with the molar mass of ethylene:

Molar mass of ethylene gas = 28 g/mol

So, $C_{C_2H_6}=3.27\times 10^{-3}mol/L\times 28g/mol=9.16\times 10^{-2}g/L$

Hence, the solubility of ethylene gas in water is $9.16\times 10^{-2}g/L$

Which best describes oogenesis?

kkurt [141]

Explanation:

Oogenesis can be defined as a process of differentiation of egg cell (ovum), into a mature ovum that further develops after fertilization. In humans, oogenesis begins in the early stage of embryonic development, during whcih primary oocyte performs meiosis I and forms secondary oocyte.
