That gives 12 atoms
Answer:
For the following reaction, 8.00 grams of silicon tetrafluoride are allowed to react with 7.40 grams of water. silicon tetrafluoride (s) + water (l) hydrofluoric acid (aq) + silicon dioxide (s) What is the maximum amount of hydrofluoric acid that can be formed? grams What is the FORMULA for the limiting reagent? H2O What amount of the excess reagent remains after the reaction is complete? grams
Answer:
31 ml
Explanation:
At constant temperature of 30°C;
Using Boyles Law:
775 × 30 = 750V2
V2 = (775 × 30) / 750 = 31ml
The correct answer is Na, Sodium metal
Electron affinity is the change in energy of a neutral atom or molecule when an electron is added to the atom to form a negative ion. In simple terms it is the likelihood of gaining an electron. Nonmetals like to gain electrons to form anions to have a fully stable electron shell, while metals lose electrons to form cations and have a stable electron shell. Argon atom for example in the gas phase; gives off energy when it gains an electron to form an ion of Argon.
