Molecules which are deficient or poor of electrons are called electron deficient molecules.

Answer:
2.448 M ≅ 2.45 M.
Explanation:
Molarity (M) is the no. of moles of solute that dissolved in 1.0 L of the solution.
M = (no. of moles of solute)/(V of the solution (L).
M = (mass/molar mass) Li₂S / (V of the solution (L))
<em>∴ M of Li₂S</em> = (500.0 g/46.4 g/mol)/(4.44 L) = <em>2.448 M ≅ 2.45 M.</em>
Answer:
0.075 moles of product formed.
Explanation:
Given data:
Number of moles of oxygen = 0.30 mol
Number of moles of oxygen = 0.15 mol
Number of moles of product formed = ?
Solution:
Chemical equation:
4Na + O₂ → 2Na₂O
Now we will compare the moles of Na₂O with oxygen and sodium.
Na : Na₂O
4 : 2
0.15 : 2/4×0.15 = 0.075 mol
O₂ : Na₂O
1 : 2
0.30 : 2/1×0.30 = 0.6 mol
Less number of moles of Na₂O are produced by sodium thus it will limit the yield of Na₂O and act as limiting reactant while oxygen is in excess.
Answer:
How much sunlight each flashlight gets (or doesn't get)
Explanation:
The independent variable is the variable that the investigator changes.
You are controlling the amount of sunlight each flashlight gets (or doesn't get).
B is wrong. The amount of decay is the dependent variable.
C is wrong. The type of plastic should be a controlled variable.
Hey there!
The independent variable is the factor that is deliberately manipulated in an experiment. The dependent variable is the variable in a relation whose value depends on the value of the independent variable.
Second, hypotheses and predictions are similar in that they are both related to an experiment. However, a hypothesis is an explanation for a phenomena that is testable through an experiment. A prediction is the expected result of an experiment.
An when conducting an experiment, it is always important to present accurate data even if that data does not support your hypothesis. If your data does not support the hypothesis, the experiment was not a waste of time. This data provides you with information regarding what is not happening in a particular phenomenon. Information gained from the experiment can help you to develop new hypotheses to test in the future.
