<span>In exothermic reactions, the products have less enthalpy than the reactants, and as a result, an exothermic reaction is said to have a negative enthalpy of reaction. This means that the energy required to break the bonds in the reactants is less than the energy released when new bonds form in the products.</span>
<span>The molar volume of a gas at STP, in liters, is 22.4
you then multiply 22.4 by 2 to get the answer to the next question:
</span><span>
You can use the molar volume to convert 2 mol of any gas to 44.8 L
</span>
<span>You can also use the molar volume to convert 11.2 L of any gas to 0.500 mol.
</span>
Avogadro’s law tells you that 1.2 L of O2(g) and 1.2 L of NO2(g<span>) are the same </span><span>numbers of moles of gas.</span>
The bad smelling element is Sulfur, which smells like rotting eggs.
Answer:
2nd and 4th ones
Explanation:
More sugar dissolves in water than salt
more aspirin dissolves in water than CO2 ...but less aspirin than table salt (NaCl)
I believe that the property referenced in 'like dissolves like" is polarity. Solvents are substances that dissolves solutes forming a solution. Solvents may be either polar or non polar; polar solvents contain bonds between atoms with very different electronegativities, such as oxygen and hydrogen, while non polar solvents have bonds between atoms with similar electronegativities such as hydrogen and carbon.
