Terri and Ernesto should both use geographic maps.
may i have brainliest? :D
The molarity of the base ( ammonium hydroxide) is calculated as follows
find the moles of Nitric acid =molarity x volume
=29.5 x 0.175 =5.163 moles of nitric acid
write the equation for reaction
HNO3+ NH4OH =NH4NO3 +H2O
by use of mole ratio between HNO3 to NH4NO3 which is 1:1 the moles of NH4OH is also 5.163 moles
molarity =moles/volume
= 5.163 /50=0.103 M is the molarity of the base
Answer:
The answer to your question is: 1, 2, 1, 2
Explanation:
1 Fe(s) + 2 Na⁺(aq) → 1 Fe²⁺(aq) + 2 Na(s)
Fe⁰ - 2e⁻ ⇒ Fe⁺² Oxidases
Na⁺ + 1 e⁻ ⇒ Na⁰ Reduces
1 x ( 1 Fe⁰ ⇒ 1 Fe⁺²) Interchange number of
2 x ( 2Na⁺ ⇒ 2 Na⁰ ) electrons
Answer:
Cells and organisms maintain a fairly constant internal environment
