Answer:
Explanation:
Zn + 2HCl = ZnCl₂ + H₂
A ) mole of Zn = 2.65 / 65
= .04 mol
mole of HCl required = .04 x 2 mol
.08 mol
If v be the volume required
v x 6 = .08
v = .0133 liter
= 13.3 cc
B )
volume of gas at NTP :
moles of gas obtained = .04 moles
= 22.4 x .04 liter
= .896 liter
we have to find this volume at given temperature and pressure
= 1.175 liter.
C )
.04 mole of zinc chloride will be produced
mol weight of zinc chloride
= 65 + 35.5 x 2
= 136 gm
.04 mole = 136 x .04
= 5.44 gm
Answer:
Each row is called a period. Each column is called a group or family.
Explanation:
Parthenolide is a sesquiterpene lactone which occurs naturally in the plant feverfew--highly concentrated in the flowers and fruit.
Answer:
NH₄⁺ (aq) + OH⁻ (aq)+ H⁺ (aq)+ Cl⁻ (aq) → NH₄⁺ (aq)+ Cl⁻ (aq)+ H₂O (l)
Explanation:
NH₄OH (l) + HCl (l) → NH₄Cl (aq) + H₂O (l)
This is called a <u>molecular equation</u> because <em>the formulas of the compounds are written as though all species existed as molecules or whole units</em>.
However, because both the acid and the base are strong electrolytes, they are completely ionized in solution. Therefore, the ionic equation is:
NH₄⁺ (aq) + OH⁻ (aq)+ H⁺ (aq)+ Cl⁻ (aq) → NH₄⁺ (aq)+ Cl⁻ (aq)+ H₂O (l)
The answer to your question is liquid hydrogen
