.8 grams of phosphorus are recommended.
Answer:If an atom loses or gains a proton, it becomes a new element. For example, if a sodium atom loses a proton, it would become a negative ion of neon. ... In nuclear reactions, like nuclear fusion, the electrons play minor roles and it is the nucleons that interact to create new elements
Explanation:
Third quarter (or last quarter)
Answer:
43.0 kJ
Explanation:
The free energy (ΔG) measures the total energy that is presented in a thermodynamic system that is available to produce useful work, especially at thermal machines. In a reaction, the value of the variation of it indicates if the process is spontaneous or nonspontaneous because the free energy intends to decrease, so, if ΔG < 0, the reaction is spontaneous.
The standard value is measured at 25°C, 298 K, and the value of free energy varies with the temperature. It can be calculated by the standard-free energy of formation (G°f), and will be:
ΔG = ∑n*G°f products - ∑n*G°f reactants, where n is the coefficient of the substance in the balanced reaction.
By the balanced reaction given:
2NOCl(g) --> 2NO(g) + Cl2(g)
At ALEKS Data tab:
G°f, NOCl(g) = 66.1 kJ/mol
G°f, NO(g) = 87.6 kJ/mol
G°f, Cl2(g) = 0 kJ/mol
ΔG = 2*87.6 - 2*66.1
ΔG = 43.0 kJ
Volume (in mL) is 1.61 ml would you need to dilute 35.0 mL of a 1.30 M solution of KBr to make a 0.0600 M solution of KBr
Dilute is to make a liquid weaker by mixing in something else
The volume or concentration of the concentrated or dilute solution can be determined by using the equation:
M₁ V₁ = M₂ V₂
Here given data is
M₁ = 1.30 M
M₂ = 0.0600 M
V₂ = 35.0 mL
V₁ =?
Then substitute this value
M₁ V₁ = M₂ V₂
1.30 M×V₁ = 0.0600 M×35.0 mL
V₁ = 1.61 ml
