Answer:
NaF(aq)
Explanation:
When sodium bromide react with fluorine sodium fluoride is formed. Florine is more reactive than bromine that's why it displace the bromine and form compound with sodium.
Chemical reaction:
NaBr(aq) + F₂(aq) → NaF(aq) + Br₂(aq)
Balanced chemical equation:
2NaBr(aq) + F₂(aq) → 2NaF(aq) + Br₂(aq)
Sodium is alkali metal and have one valance electron. It loses one electron and show +1 charge. While all halogen elements need one electron to complete the octet and show -1 charge.
That's why one halogen atom is combine with one sodium atom to make overall compound neutral.
Answer:
This question is asking to state the hypothesis for the given scientific question. A possible hypothesis will be:
IF an organized binder is used, THEN students will turn in an increased amount of homework/more homework.
Explanation:
A hypothesis in an experiment is a testable explanation to a problem. It is a predictive statement given in order to provide a possible solution to an observed problem or scientific question. A hypothesis must be subject to testing via experimentation in order to determine whether to accept or reject it. It must not be true, instead it is just a possible answer to a problem. Hypothesis is usually written in the OF, THEN format.
In this question, a scientific question states: How does the use of an organized binder affect the amount of homework a student turns in? Based on the explanation above, a hypothesis to this question will be:
IF an organized binder is used, THEN students will turn in more homework.
Answer:
63.25 grams of CO₂
Explanation:
To convert from liters to grams, we first need to convert from liters to moles. To do this, we divide the liters by 22.4, the amount of liters of a gas per mole.
32.2 / 22.4
= 1.4375 moles of CO₂
Now we want to convert from moles to grams. To do this, we multiply the moles by the molar mass of CO₂. The total molar mass can be found on the periodic table by adding up the molar mass of carbon (12) and two oxygen (32).
12 + 32 = 44
Now we want to multiply the moles by the molar mass.
1.4375 • 44
= 63.25 grams of CO₂
This is your answer.
Hope this helps!
Answer:
wdescribes the probability of finding an electron in space.
Explanation:
The quantum mechanical model of the atom assigns wave properties to the electron. This is in accordance with Heisenberg's uncertainty principle.
The probability of finding the electron in a given volume element is given as the square of the wave function while the wave function itself does not really have a physically significant meaning.
However, the wave function is a mathematical function that contains a detailed information about the behavior of an electron.
Answer:
dilute solution
A solution containing less solute than the equilibrium amount is called a dilute solution. The solvent has a limited capacity to dissolve a solute.
