In order to balance this equation you need to count each element and how many of the individual elements are in the equation. _H2+N2=2 NH3 You multiply the 2 (Which is the coefficient) by the 3 (which is the subscript) This would equal 6 which indicated there are 6 hydrogen atoms on the right side so the left side should also have 6 hydrogen atoms
The missing coefficient on the left side must multiple the 2 to become 6 hydrogen Answer=3
Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster.
2.50 moles (55.85gramsof Fe/ 1 mole) (6.02 x 10^23 atoms / 1) = 8.41 x 10^25 because there is only one Iron present in the compund.
Answer:
Bohr Atomic Model : In 1913 Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus. ... To remedy the stability problem, <em><u>Bohr modified the Rutherford model by requiring that the electrons move in orbits of fixed size and energy.</u></em>
Answer:
17.03Pa
Explanation:
Given parameters:
Initial volume = 15.5kL
Final volume = 6kL
Final pressure = 44Pa
Unknown:
Original pressure = ?
Solution:
The parameters given shows pressure and volume relationship of the given gas. One of the gas laws that predicts pressure - volume relationships is the Boyle's law.
Boyle's law states that "the volume of a fixed mass of gas varies inversely as the pressure changes, if the temperature is constant".
Mathematically,
P₁V₁ = P₂V₂
where P₁ is the initial pressure
V₁ is the initial volume
P₂ is the final pressure
V₂ is the final volume
Input the variables and solve for P₁;
P₁ x 15.5 = 44 x 6
P₁ = 17.03Pa
