Unknown elements W and X formed the compound image during a reaction. If element W has one valence electron, element X most likely has how many valence electrons
Answers
Answer:
I can't see the compound image but the safe guess here is that there is now noble gas config for the molecule so likely X has 7 valence electrons kind of like Na being W and Cl being X

What is the formula of a compound that has [1 mol Fe], [1 mol Ti], and [3 mol O]
Answers
Answer: [tex]FeTiO_3[/tex]
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
The molecular formula for a compound that has [1 mol Fe], [1 mol Ti], and [3 mol O] will be [tex]FeTiO_3[/tex]
what are buffers and why are they important
Answers
Explanation:
A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base,thus maintaining the pH of the solution relatively stable.This is important for processes and/or reactions which require specific and stable pH ranges.

What is the ratio of the effusion rate of the helium to methane? (round to hundreds)
Answers
Answer:
2.00
Explanation:
From Graham's law; the rate of effusion is inversely proportional to the square root of the relative molecular mass.
Let the rate of effusion of Helium be R1
Let the rate of effusion of Methane be R2
Let the molecular mass of Helium be M1
Let the molecular mass of Methane be M2
Hence;
R1/R2 = √M2/M1
R1/R2 = √16.0294/4.0026
R1/R2 = 2.00

Why are large differences in temperature between the wet bulb and dry bulb thermometers are possible only at higher temperatures?
Answers
Answer:
At constant vapor pressure, the relative humidity decreases as the temperature increases, therefore, at higher temperature the relative humidity is low and water readily evaporates from the wet bulb thermometer that results in the cooling of the bulb such that at a given ambient temperature the very low relative humidity results in very large differences between the temperatures of the wet bulb thermometer and that of the dry bulb thermometer and the wet bulb is observed to be the colder thermometer of the two
