Answer:
4 Sb (+3) + 2 Br (2) O (3) ----> 4 SbBr + 3 O(-2)
In the equation, place the valences in parentheses and the stoichiometric balance numbers so that the reaction is balanced, place them in bold.
Explanation:
In this chemical equation it seems to me that the valences of BrO are wrong.
That is why I will complete the equation, demonstrating the chemical reaction, and also use the appropriate valences.
Assuming that Sb has a valence of +3 and that the Br that appears in the form of oxide with oxygen (valence -2) has a valence of +3 (because -3 does not exist as valence or oxidation state of bromine).
Weather
Explanation:
Meteorology is the study of weather.
Meteorologists are scientists that helps to predict weather phenomenon around us.
The use several data gathered from different weather stations around to make precise predictions about the likelihood of a particular weather condition.
Meteorologists most times use computer models to predict and forecast both long and short term weather conditions.

1- We have to get the molar mass of calcium bromide, by getting the chemical formula ( CaBr2).
From the chemical formula, we have to get the molecular weight for each of Ca&Br on the periodic table:
Ca = 40.078 & Br = 79.904
* from the chemical formula ( CaBr2) so, the molecular weight of calcium bromide is:
40.078 + 2x(79.904) = 199.89
2- number of moles = weight / molecular weight
=20.275 / 199.89 = 0.1014 moles
3- where the volume of solution by littre = 575 mL/ 1000 = 0.575 L
So,
4-Molarity = moles of solute / L of solution
= 0.1014 / 0.575 = 0.1763 mol/L
Answer: 41.2 atm
Explanation
To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
Putting values in above equation, we get:
The maximum pressure (in atm) that will be attained in the tank before the plug melts and releases gas is 41.2
