The answer to this question would be: too low
Molar mass would be determined by the number of mol and the mass of the object. Mass wouldn't be influenced by the temperature, but number of mol is. Using ideal gas formula of PV=nRT you can conlude that the amount of mol(n) is inversely related to the temperature (T).
If the temperature is higher than it supposed to be, then the amount of mol would be lower than it supposed to be.
Answer:
Co is made from incomplete combustion.
Explanation:
This essentially means if you have a fire, and not enough fuel for the fire to burn, co will always consequently be made.
Answer:
pH range of indicator is 5.4 to 7.4
Explanation:
An acid-base indicator are chemical substances that change in color when pH changes.
An indicator changes in color when the pH of the solution is equal to pKa of the indicator (Where pKa is defined as - log Ka).
<em>The pH range in which indicator changes in color is pKa ± 1.</em>
<em />
pKa of buffer is:
- log 4x10⁻⁷ = <em>6.4</em>
That means pH range of indicator is since 6.4 - 1 = <em>5.4</em> to 6.4 + 1 =<em> 7.4</em>.
<em>(5.4 - 7.4)</em>

Explanation:
The atomic radius (r) of an atom can be defined as one half the distance (d) between two nucli in a diatomic molecule. Atomic radii have been measured for elements. The units for atomic radii are picometers, equal to 10−12 meters.
Democritus (460-370 BC) was a Greek philosopher who theorized that all matter could be reduced to particles that could not be divided, which he described as “atomos.”
John Dalton (1766-1844) Proposed the atomic theory.
