Calculate the mass of argon gas in 40.0 L at STP

Hi, I have a question that how to increase the melting point of car wax polish? I have made a polish which works great but it is melted at 28 degree Celsius where as it should not melt at as low as 50 degrees so kindly suggest me what I do with the formula, process or what I add to enhance my product's melting point?

Thanks

Find the value for solution with pH=7.0 and pe = 8.0 for the following.

(Fe³⁺)/(Fe²⁺) ratio

Find the value for solution with pH=7.0 and pe = 8.0 for the following.

1. (NO₃^-) / (NH₄⁺) ratio

Express the oxidation and reduction half reactions of the following.

(MnO₄^-+Mn²⁺) to MnO₂(s).

Let us compare things! Identify two plant species from your backyard or residence that might seemingly have the same leaf size based on its leaf length. Collect seven (7) leaf samples for each plant and measure each of its lengths using the same ruler or measuring tape. Is there any difference in the mean leaf length between the two plant species? If so, kindly show statistically. (Test each data set for any outliers).

Provide the correct answer. Submit your solution in the gclass. Consider the reaction below. If 10.10 moles H2 are made to react with 8.64 moles N2, a. what is the limiting reagent? b. How many grams of NH3 will be produced? c. What reagent is in excess and by how much? d. Compute for its percent yield if 78.09 g was produced. See answer format.
