The $ -(Br) at that instant is calculated as follows
BrO3 + 5Br ---> 3Br2 + 3 H2o
by use of reacting ratio BrO3 to Br2 which is 1:3
therefore $ of Br = 3 x (1.5 x10^-2)= 4.5 x10^-2
Answer:
The answer to your question is n = 0.838 moles
Explanation:
Data
Volume = 2.15 l
Pressure = 8.91 atm
Temperature = 5.81°C
moles = ?
Gas constant = 0.082 atm l / mol°K
Process
1.- Convert temperature to °K
Temperature = 5.81 + 273 = 278.81°K
2.- Write the Ideal gas formula
PV = nRT
-Solve for moles (n)
n = PV / RT
3.- Substitution
n = (8.91 x 2.15) / (0.082 x 278.81)
4.- Simplification
n = 19.16 / 22.86
5.- Result
n = 0.838 moles
Answer:
Q = 19255.6 j
Explanation:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Given data:
Mass of water = 46 g
change in temperature = ΔT = 100-0.0 = 100 °C
Heat absorbed by water = ?
Solution:
Specific heat capacity of water = 4.186 j/g. °C
Q = m.c. ΔT
Q = 46 g×4.186 j/g. °C×100 °C
Q = 19255.6 j
Answer:
sigma bond
represents two electrons
Explanation:
The bond between hydrogen and oxygen is sigma bond because the bond between hydrogen and oxygen is covalent means sharing of electron takes place between two atoms and we know that sigma bond is also occurs in a covalent bond in which overlapping of atomic orbitals or hybrid orbitals along the bond axis occurs. Both also represent two electrons because both atoms share one electron each so we can say that the two atoms represents two electrons.
