Answer:
New temp = 135°C
Explanation:
From ideal gas equation
But; P1 = 10000Pa. P2 = 45000
V1 = 200 cc. V2 = 100 cc
T1 = 60°C. T2 = ??
From our formulae above
then T2= 45000×100×60÷ (10000×200)
T2= 135°C
The balanced equation for the acid base reaction is as follows
NaOH + HCl ---> NaCl + H₂O
stoichiometry of NaOH to HCl is 1:1
the number of NaOH moles reacted - 0.200 mol/L x 0.0250 L = 0.005 mol
according to molar ratio
number of NaOH moles reacted = number of HCl moles reacted
therefore number of HCl moles - 0.005 mol
volume of 30.0 mL contains 0.005 mol
therefore 1000 mL contains - 0.005 mol / 0.030 L = 0.167 M
concentration of HCl is 0.167 M
4-nonanone
Explanation: there is a functional group in the compound CH3CH2CH2CH2CH2COCH2CH2CH3 which is a ketone; So for naming a ketone we must first mention the name of the prefix that is correspond then add the suffix ''one''. And why I putted a ''4'' before the name is because we must indicate where this functional group is located, for doing that we have to start counting where the functional group is the closet to the end of the compound so when looking we should start to count on the right side. this is how I get 4-nonanone
Answer:
MgCl₂ + H₂ ---> 2 HCl + Mg
Explanation:
Since you have not given any products, I am going to assume that this is a single-displacement reaction. In these types of reactions, an element is being swapped for another in a compound. The unbalanced equation would look like this:
MgCl₂ + H₂ ---> HCl + Mg
Mg does not have a subscript of 2 because it can exist by itself. As you can see, the reaction is not balanced. On the left side, there is 1 Mg, 2 Cl, and 3 H. On the right side, there is only 1 of each. The balanced equation would look like this:
MgCl₂ + H₂ ---> 2 HCl + Mg
Now, there is 1 Mg, 2 Cl, and 2 H on both sides.
