63.5 gm cu contain 6.02*10^23 molec
1 gm cu contain 6.02*10^23/63.5
3.14 gm contain 6.02*10^23*3.14/63.5
similary in case of H2
1.10*6.02*10^23/2
then you can compare the result
You picked the correct answer. Its amorphous solid. Good luck on the rest!
Answer:
tetrahedral geometry
<h3>CHCH2O- CH2CH3</h3>
Explanation:
There are several centers of interest. Each carbon with all single bonds is the center of a tetrahedral geometry.
Answer: Option (C) is the correct answer.
Explanation:
Stoichiometric coefficients represents the number of individual atoms involved in the chemical equation.
As a result, stoichiometric coefficients help in balancing the equation because an equation can only become balanced when number of reactant molecules equal the number of product molecules or vice versa.
Therefore, we can conclude that a chemical equation can be used to solve stoichiometry problems provided that it includes the coefficients that are needed for balancing the equation.
Answer:
Earthquakes happen when rock below the Earth's surface moves abruptly. Usually, the rock is moving along large cracks in Earth's crust called faults. Most earthquakes happen at or near the boundaries between Earth's tectonic plates because that's where there is usually a large concentration of faults.
