I’m pretty sure it’s (B) tropical storm but I’m not sure
Answer:
Explanation:
To solve problems like this, the very first thing to do is to write out the balanced equation for the process. The reaction is
Zn(s) + HCl(aq) → ZnCl2(aq) + H2(g)
and the balanced equation is
Zn(s) + 2 HCl(aq) → ZnCl2(aq) + H2(g)
So, by examining the stoichiometry, you can see that for every mole of Zn, two moles of HCl will be required. In turn, we need to know the number of moles of Zn is represented by 10.4 g. The molecular weight of Zn is 65.38 g/mol so
moles of Zn = 10.4 g/65.38 g/mol = 0.159 moles
and, twice as many moles of HCl is required so
# of moles of HCl required = 2 * 0.159 = 0.318 moles
I think the resistance and it does not led the cold enter in your house
the control group is what you compare to what you are testing. For example im trying to find which liquid has the most properties to water liquid a b c or d. My control group is water.
Carbon is more electronegative
