23492u undergoes alpha decay. what is the atomic number of the resulting element.
mash [69]
Alpha decay involves the loss of an alpha particle, aka a helium nucleus. This results in the mass number of the original element decreasing by 4 and the atomic number decreasing by 2. Assuming 23942u is uranium (92), the resulting element's atomic number is 90, making it thorium.

Stels [109]

Answer:

Explanation:

heat released  by the solution

= 120 x 3.18 x ( 25 - 14 )

= 4197.6 J

= 4.1976 kJ

This is the heat gain by the salt

so enthalpy change = +  4.1976 kJ

because there is increase  in enthalpy

It is endothermic process .

If the volume occupied by 0.500 mol of nitrogen gas at 0°C is 11.2 L, then the volume occupied by 2.00 mol of nitrogen gas at th
Paraphin [41]
Avagadros law states that volume of gas is directly proportional to number of moles of gas at constant pressure and temperature.
\frac{V1}{n1} =  \frac{V2}{n2}
where V -volume , n - number of moles 
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation 
substituting these values in the equation 
\frac{11.2 L}{0.500 mol} =  \frac{V}{2.00 mol}
V = 44.8 L 
answer is C. 44.8 L
