Answer is: <span>the missing daughter nucleus is rhodium (Rh).</span>
Nuclear
reaction: ¹⁰⁶Ru → ¹⁰⁶Rh + e⁻(electron) +
ve(electron antineutrino).
Beta decay is radioactive decay in which a beta
ray and a neutrino are emitted from an atomic nucleus.There are two types of
beta decay: beta minus and beta plus.
<span>In beta minus decay,
neutron is converted to a proton and an electron and an electron antineutrino.
In beta plus decay, a proton is converted to a neutron and positron and an
electron neutrino, so mass number does not change.</span>
Solute - substance that dissolves.
alcohol - solute
water - solvent
Answer:
Its melting point is 17 °C.
Explanation:
- The melting point of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium.
<em>So, the melting point is 17 °C.</em>
And this is shown in the figure attached.
You can use the formula: C = k - 273 to solve this problem. C stands for Celsius, and k stands for kelvin. Given the information that the Kelvin is 172k, then you can plug it into the equation and get C = (172) - 273. The correct melting point in C is -101°C. Hope this helped!
Answer:
61.3 g/mol
Step-by-step explanation:
We can use the <em>Ideal Gas Law</em> to solve this problem:
pV = nRT
Since n = m/M, the equation becomes
pV = (m/M)RT Multiply each side by M
pVM = RT Divide each side by RT
M = (mRT)/(pV)
<em>Data:
</em>
m = 0.675 g
R = 0.0.083 14 bar·L·K⁻¹mol⁻¹
T = 0 °C = 273.15 K
p = 1 bar
V = 250 mL = 0.250 L
<em>Calculation:
</em>
M= (0.675 × 0.083 14 × 273.15)/(1 × 0.250)
M= 15.33/0.250
M= 61.3 g/mol
