Answer:
The answer to your question is: 0.3 moles of AgNO₃
Explanation:
1.0 L sample
0.1 mol of NaCl
0.1 mol of CaCl₂
AgNO₃ = ? moles
Reactions
NaCl + AgNO₃ ⇒ AgCl + NaNO₃
Then 1 NaCl mol --------------- 1 AgNO₃
0.1 mol -------------- x
x = 0.1 moles of AgNO₃ needed
CaCl₂ + 2 AgNO₃ ⇒ 2 AgCl + Ca(NO₃)₂
Then 1 mol of CaCl₂ ------------- 2 moles of AgNO₃
0.1 mol ------------- x
x = 0.2 moles of AgNO₃
Total moles of AgNO₃ = 0.1 + 0.2 = 0.3
A mineral found in a bridge is iron
If the ratio of mass to volume is higher, then density is higher. If the ratio of mass to volume is lower, the density is lower.
Equal pressures from the ideal gas equation (P = nRT/V) ... same moles, T and V... P must be the same. <span>Lighter gas has greater RMS speed .... KE = 1/2mv² mass and speed inversely proportional </span>
<span>Same KE .... all gases at same T have same KE </span>
