A cold front is the leading edge of a cooler mass of air, replacing at ground level a warmer mass of air, which lies within a fairly sharp surface trough of low pressure.
Calcium will loose one electron. Fluorine will gain one electron. Lithium will loose one electron. Argon will not loose any because it already has a full valence level. Aluminium will loose 3 electrons.
The percentage of dissolved salt in saltwater
is 3.5%. We are given the amount seawater sample. <span>We would just multiply the two values together.
750 g (0.035) = 26.25 g NaCl
26.25 g NaCl ( 1 mol / 59.44 g ) ( 1 mol Na / 1 mol NaCl ) ( 22.99 g / 1 mol ) = 10.15 g Na
Hope this answers the question. Have a nice day.</span>
Answer:
Volume is directly proportional to absolute temperature.
Explanation:
We Know, Atomic number of Uranium = 92
Molar mass in given species = 233
Now, Molar mass = Number of Protons + Number of Neutrons
233 = 92 + x
x = 233 - 92
x = 141
So, your final answer is 141
Hope this helps!
