Answer:
Un río aluvial es aquel en el que el lecho y las riberas están formados por sedimentos móviles y / o suelo.
Explanation:
The products of reaction are ZnSO4 and H2. Since ZnSO4 is in aqueous form (aq), therefore only H2 and water vapor contributes to the overall total pressure in the system.
Total Pressure = 764 torr = H2 partial pressure + Water partial pressure
Since Water partial pressure is 26.74 torr so,
H2 partial pressure = 737.26 torr = 0.97 atm
Answer:
3.96 × 10⁻³ mol Pb
Explanation:
Step 1: Find molar mass
Pb (Lead) - 207.2 g/mol
Step 2: Use Dimensional Analysis
= 0.003962 mol Pb
Step 3: Simplify
We have 3 sig figs
0.003962 mol Pb ≈ 0.00396 mol Pb
0.00396 mol Pb = 3.96 × 10⁻³ mol Pb
A 10.0cm3 volume of alcohol has a mass of 7.05g. is the density
Answer:
<u>Explanation:</u>
The ratio between the mass of a substance and its unit volume is referred as density.
is the Answer
<u>Note:</u>
1000 g = 1 kg
100 cm = 1 m
When we used to transform the given values into S.I units, then
Alcohol’s volume can be written as,
Alcohol’s mass can denote as,
Then,
