1. Blood is an organic compound
2. B)
C.
Their radiation facilitates nuclear fusion in young stars.
The balanced equation for the above reaction is as follows;
2HCl + K₂SO₃ ---> 2KCl + H₂O + SO₂
stoichiometry of HCl to SO₂ is 2:1
number of moles of HCl reacted - 15.0 g / 36.5 g/mol = 0.411 mol
according to molar ratio
number of SO₂ moles formed - 0.411 mol /2 = 0.206 mol
since we know the number of moles we can find volume using ideal gas law equation
PV = nRT
where
P - pressure - 1.35 atm x 101 325 Pa/atm = 136 789 Pa
V - volume
n - number of moles - 0.206 mol
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature - 325 K
substituting values in the equation
136 789 Pa x V = 0.206 mol x 8.314 Jmol⁻¹K⁻¹ x 325 K
V = 4.07 L
volume of SO₂ formed is 4.07 L
Answer:The molecules in a raw egg absorb the heat energy, they use this energy to change shape
Such a chemical reaction is said to be endergonic, which means 'energy in'.
Egg molecules will never undergo these reactions without the input of energy (usually in the form of heat)
I hope this helps, if not, let me know :)
Answer:
conductors of electricity when in liquid or aqueous state
high melting point
soluble in water
Explanation:
An ionic substance is any substance that is composed of two ions of opposite charge.
In the solid state, ionic substances do not conduct electricity because the ions are trapped inside the crystal. When in liquid state or in aqueous solution, these ions are now free and the solution becomes an electrolyte.
All ionic substances have a very high melting point and dissolve in water easily.
