Answer:
thanks to all the mortal those who are born must die one day that it cut in cannot be avoided as ripe fruit fall of the tree so it is common to all the mortal those who are born must die one day that it cut
Explanation:
silghjnb bj i bb b nv bv hc U and lamenting produce a few of the tree so much for your time is common to both of us ☺️ to all the said that death of the tree so it cut in cannot be avoided as well as well but the mortal Kombat X the said
Answer: 1 molecule of 
reacts with 1 molecule of 
to give 2 molecules of HCl.
1 mole of reacts with 1 mole of to give 2 moles of HCl.
Explanation:
The given balanced reaction is:
On the particulate level :
1 molecule of reacts with 1 molecule of to give 2 molecules of HCl.
On molar level:
1 mole of reacts with 1 mole of to give 2 moles of HCl.

The heating of the water will have 3 phases
1. Melting of the ice, the temperature will remain constant at 0 degrees C
2. Heating of water to boiling, the temperature will rise
3. Boiling of water, temperature will remain constant at 100 degrees C
So, let's see how many cal are needed for each phase.
We start with 320 g of ice and 100 g of liquid, both at 0 degrees C. We can ignore the liquid and focus on the ice only. To convert from the solid to the liquid, we need to add the heat of fusion for each gram. So multiply the amount of ice we have by the heat of fusion.
80 cal/g * 320 g = 25600 cal
Now we have 320 g of ice that's been melted into water and the 100 g of water we started with, resulting in 320 + 100 = 420 g of water at 0 degrees C. We need to heat that water to 100 degrees C
420 * 100 = 42000 cal
Finally, we have 420 g of water at the boiling point. We now need to pump in an additional 540 cal/g to boil it all away.
420 g * 540 cal/g = 226800 cal
So the total number of cal used is
25600 cal + 42000 cal + 226800 cal = 294400 cal</span>
Answer:
I cant see the picture but
heeeerrrrreeeee
multiply the number of each atom with its molecular mass. (see the periodic table)
5*12 + 12*1 = 72 gram per mole.
Or more accurately: 5*12.01078 + 12*1.007947 = 72.149264 g/mole
