Answer:
Explanation:
Hello there!
In this case, according to the given information, it turns out firstly necessary to write out the described chemical reaction as shown below:
Now, we set up the expression for the calculation of the standard free energy change, considering the free energy of formation of each species, specially those of H2 and F2 which are both 0 because they are pure elements:
Regards!
Answer:

Explanation:
if the baby flower is purple the parents were purple
Answer: 584 mm Hg
Explanation:
According to Raoult's law, the partial pressure of a component at a given temperature is equal to the mole fraction of that component multiplied by the total pressure.
where, x = mole fraction
= total pressure = 749 mmHg
Putting in the values we get:
The partial pressure of nitrogen will be 584 mmHg
Lithium sulfide (Li2S) would have 2 lithium atoms for every sulfur atom and would form an ionic bond. Sodium oxide (Na2O) has 2 sodium atoms for every oxygen atom (same ratio) and forms an ionic bond.
C) 6.781 g
Explanation:
Precision in a reading is the ability to reproduce the same set of results.
Accuracy is the nearness of the measured value to the true value.
Every measurement must be taken accurately and precisely.
Now to determine the value of the block's mass that would be the most precise, let us arrange the masses in their increasing order.
6.759 g, 6.786 g, 6.812 g, 6.779 g
Arranging in increasing order;
6.759 g , 6.779 g, 6.786 g 6.812 g
An value from the option that falls within the given values will make it even more precise;
6.781 g would perfectly fit this condition.
Other values are lower or higher than the given sets.
