Answer:
The answer is
<h2>155 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of bromine = 50 mL
density = 3.10 g/cm³
It's mass is
mass = 50 × 3.10
We have the final answer as
<h3>155 g</h3>

Iam sorry I don't know but why Iam messaging iss because when more people message it usually appears to more people so someone else will be able to help you:)
Answer:
Calcium atoms have smaller radii than potassium atoms since calcium atoms have a greater nuclear charge. Each calcium atom will be closer to the delocalized electrons. Thus, the bonds in calcium will be stronger than that in potassium.
Explanation:
Answer:
The two ions would be Na: Sodium and Cl: Chloride.
<span>Enthalpy
change is the total heat that is absorbed or evolved in a certain reaction that
is being carried in a constant pressure system. It can be calculated by the
product of the specific heat of the substance and the difference of the final
temperature and the initial temperature. For this case, the enthalpy of combustion is given, so we simply multiply the amount of octane present to the enthalpy given to determine the total heat that is released.
Heat = 75 g ( 1 mol / 114.23 g ) (- 5500 kJ / mol ) = - 3611.14 kJ
The negative sign in the calculated value represents that this heat is being released in the process.</span>
