Answer:
0.0064 qt
Explanation:
Given data:
Density of mercury = 13.6 g/cm³
Mass of mercury = 83.0 g
How many quarts mercury have = ?
Solution:
First of all we will calculate the volume in cm³.
d = m/v
13.6 g/cm³ = 83.0 g / volume
Volume = 83.0 g / 13.6 g/cm³
Volume = 6.1 cm³
cm³ to L:
6.1 cm³ × 1 L / 1000 cm³
0.0061 L
In quarts:
1 L = 1.06 qt
0.0061 L × 1.06 qt / 1 L
0.0064 qt
Fusion and fission are both nuclear reactions that produce energy, but fusion is two nucleus joining (think about fuse or fusing), while fission is a nucleus splitting (think about fissure)
so the correct answer is <span>C. Fission is the splitting of a nucleus</span>
Molar mass NaOH =23+16+1=40 g/mol
<span> 0.100 M= 0.100 mol/L
</span>500 ml=0.500 L
0.500L*0.100 mol/L=0.0500 mol NaOH we need to prepare 500 ml solution
0.0500 mol NaOH*40g/1mol=2 g NaOH we need to prepare 500 ml solution
we need 2 g NaOH, dissolve it in small amount of water, and dilute it with water up to 500 mL
