Answer : The concentration in mol/L is
Explanation : Given,
Moles =
Volume of solution = 500 mL
Formula used :
Now put all the given values in this formula, we get:
Therefore, the concentration in mol/L is
Answer:
0.045 L or 45 mL
Explanation:
Moles = Mass/M.Mass
Moles = 10 g / 109.94 g/mol
Moles = 0.09 moles
Also,
Molarity = Moles / Vol in L
Or,
Vol in L = Moles / Molarity
Vol in L = 0.09 mol / 2 mol/L
Vol in L = 0.045 L
Answer:
it's C
Explanation:
The volume measurement 0.100 L consists of 3 significant digits, counting the non-zero digit and the zero after the decimal point.
In the volume measurement 0.100 L, there are 3 significant figures. Significant figures represent the precision of a measured value. In this case, the zeroes after the decimal point are 'leading zeroes' which are not counted as significant. The '1' is a non-zero digit, which is always significant. And the zero after '1' is a 'trailing zero' that comes after a decimal point, so it is also counted as significant. Therefore, the number of significant figures in 0.100 L is 3.

By breaking a carbon double bond and adding chlorine.
By removing hydrogen because of chlorine’s attraction to hydrogen’s nucleus.
Chlorine and ethene do not react spontaneously.
Answer: option B m
Explanation:
It is an example for Electrophilic Addition of Halogen. And addition of Cl2 to Alkene is always Trans Addition. That means both cl atoms should add opposite side of double bond and results vicinal 1,2-dichloroethane as a product.
CH2=CH2 + Cl2-------> ClCH2CH2Cl
Answer: The moles of product present in the vessel is 0.092 moles
Explanation:
For the given chemical equation:
We are given:
Initial moles of reactant = 0.200 moles
Unreacted moles of reactant = 0.108 moles
Reacted moles of reactant = 0.200 - 0.108 = 0.092 moles
By Stoichiometry of the reaction:
1 mole of reactant produces 1 mole of product
So, 0.092 moles of reactant will produce = of product
Hence, the moles of product present in the vessel is 0.092 moles
formation of these mountains?
O The crust is compressed
O The crust does not spread apart
The center block is forced upward.
The hanging walls from the two parallel faults slip down
The Formation of these mountains will be caused by
Options B, C, and D is correct.
Generally, a mountain is simply defined as a body that rises dramatically above its surroundings and is distinguished by steep slopes.
In conclusion, Mountains are formed from the formation of rocks over years in an Environment.
