Balanced equation is
2NaOH + H2SO4 ---> Na2SO4 + 2H2O
(the last compound is H2O NOT H2)
Not sure about the ionic equation
Answer: Thr reactions are balanced because both have the same products so they are balanced. This represents a balanced graph
Explanation:
Answer:
12.01% by mass
Explanation:
Percent by mass is 100 times the mass of solute (ammonia) over the mass of the solution. In molarity, we have the moles of ammonia per liter of solution. There are 6.70moles of NH3 in 1L. Thus, we need to convert the moles of ammonia to grams and the liters of solution to grams:
<em>Mass ammonia - Molar mass: 17.031g/mol-</em>
6.70moles * (17.031g / mol) = 114.1g NH₃
<em>Mass solution:</em>
1L * (1000mL / 1L) = 1000mL * (0.950g/mL) = 950g
Percent by mass:
114.1g NH₃ / 950g * 100 =
<h3>12.01% by mass</h3>
The correct answer is option C, that is, the universal law of gravitation.
According to Newton's law of universal gravitation, every particle fascinates every other particle in the universe with a force that is directly equivalent to the product of their masses and inversely proportional to the square of the distance between their centers. This is a usual physical law obtained from empirical observations by what Isaac Newton knew as inductive reasoning.
