There are 2 Ca, 4 H (2*2) and 4 O (2+2) on the left hand side. So there should be the same number of atoms 2Ca and 4(O+H) on the right hand side. The reaction is a synthesis (making something new), rather than a decomposition (destroying something).
The answer is Two molecules of Ca(OH)2 should be produced during the synthesis reaction.
Its tetrahedral since there's four chlorine molecules around carbon
Answer:
10.304 kPa
Explanation:
n=mol nitrogen (N2) gas=2moles
Temperature=T=310 K
Volume=0.5 L=0.5 dm3
R=8.31 J K−1 mol−1
From Gerenal gas equation we know that
PV=nRT
P=nRT/V
Putting the values
P=(2*8.31*3100/(0.5)
P=10.304 kPa
or P=10304 Pa
Answer:
Maybe B, try that Im sorry if I'm wrong
Answer:
8 gm
Explanation:
NaOH molar weight = 22.989 + 15.999 + 1.008 = 39.996 gm
.5 M would contain 1/2 of this per liter = 19.998 gm
now you only want 400/1000 of a liter = 7.9992 gm ~ 8gm
