Answer:
Explanation:
Hello there!
In this case, since the percent by mass of a solute in a solution is computed via the following division:
Next, given the mass of HCl and that of water, we plug them in to obtain:
Best regards!
Bonds between carbon and oxygen are more polar than bonds between sulfur and oxygen. nevertheless, sulfur dioxide (SO₂) exhibits a dipole moment while carbon dioxide (CO₂) does not because of the difference in their shape, CO₂ is having linear geometry thus exhibit zero dipole moment while SO₂ is having bent shape thus exhibit dipole moment. So, despite the fact that bonds between carbon and oxygen are more polar than bonds between sulfur and oxygen. nevertheless, sulfur dioxide (SO₂) exhibits a dipole moment while carbon dioxide (CO₂) does not.
Answer:
The final temperature (in degrees Celsius) of the iron block is 85.82 °C
Explanation:
<u>Determine the heat emitted by the condensing water.</u>
qw = 0.88 g H2O
qw = -2.1492 kJ
<u>Determine the heat absorbed by the iron block</u>
qw = - qw = - (-2.1492 kJ) = 2.1492 kJ
<u>Look up the specific heat for iron. Use the specific heat equation to solve for the final temperature of the iron block.</u>
q = mcΔT
ΔT = q / mc
Temp f = (q / mc) + Temp i
Temp f = 2.1492 x 10^3 J / 75 g (0.449 J/g.°C) + 22 °C
Temp f = 85.82 °C
Answer:
= 13.0 moles O2
Explanation:
1] Given the equation: 2C8H18 + 25 O2 ----> 16CO2 + 18H2O
a. How many moles of oxygen gas are required to make 8.33 moles of carbon dioxide?
8.33 moles CO2 X
25mol O2
16mol CO2
= 13.0 moles O2
