Answer:
First, it is easiest if you write the compete molecular equation:
AgNO3(aq) + KCl(aq) ==> AgCl(s) + KNO3(aq) .. molecular equation.
You must also know or look up which compounds are soluble (aq) and which are not (s). In this case, silver chloride (AgCl) is not soluble. Thus, the net ionic equation is...
Ag+(aq) + Cl-(aq) ==> AgCl(s)
Answer:
A. 1350
You multiply 18.21HNO3* 1mol MgN2O6 * 148.30MgN2O6
Then divide it by the 2mol HNO3 to get 1350
Answer: Metals tend to gain electrons.
Explanation: Hope this helps!!! Have an amazing day!
I believe the response should be D. Heat is absorbed by the system and there is a positive change in enthalpy.
Answer:
a) CH4 (g) (1 mole) + H2O (g) (1 mole) = CO (g) + 3H2 (g) (3 moles).
b) 3/1 or 3 will be the conversion factor used to convert moles of methane and the moles of hydrogen.
c) Based on the given mole-mole relation,
The number of moles of hydrogen produced by 1 mole of CH4 or methane is 3 moles. Therefore, the number of moles of hydrogen produced from 7 moles of CH4 would be,
3/1 * 7 = 21 moles.
d) The formation of 3 moles of hydrogen is taking place from 1 mole of water vapor or H2O. Therefore, the number of moles of water vapor required to produced 100.50 moles of hydrogen would be,
1/3 * 100.50 moles = 33.5 moles.
