Answer:
"One mole of any gas has a volume of 24 dm3 or 24,000 cm3 at rtp (room temperature and pressure). This volume is called the molar volume of a gas."
Explanation:
Divide the mass of neon.
Answer:
3.2 × 10⁻⁸
Explanation:
Let's consider the solution of magnesium carbonate.
MgCO₃ ⇄ Mg²⁺(aq) + CO₃²⁻(aq)
We can relate the molar solubility (S) with the solubility product (Ksp) using an ICE chart.
MgCO₃ ⇄ Mg²⁺(aq) + CO₃²⁻(aq)
I 0 0
C +S +S
E S S
The Ksp is:
Ksp = [Mg²⁺] × [CO₃²⁻] = S × S = S² = (1.8 × 10⁻⁴)² = 3.2 × 10⁻⁸
Answer:
In this activity, we will pretend that nuts, washers and bolts are 3 kinds of elements. A single washer represents an atom of WASHER. A single nut represents an atom of NUT and a single bolt represents an atom of BOLT. Atoms can be put together to form compounds.
SI unit- Quantity
second- time
kilogram- mass
kelvin- temperature
ampere- electric current
S.I. Unit of time is second.
S.I. Unit of mass is kilogram.
S.I. Unit of temperature is kelvin.
S.I. Unit of electric current is ampere.
So match will be as follows:
second- time
kilogram- mass
kelvin- temperature
ampere- electric current
