Suitable hypothesis for the experiment is as temperature increases rate of reaction also increases.
<h3>What is rate of reaction?</h3>
Rate of any reaction gives idea about the speed of the completion of that reaction.
Rate of reaction will be affected by many factors are some such factors are:
- Dependent variable: Rate of change of the chemical species which are present in the reaction is the dependent variables.
- Independent variable: Independent variable is temperature as it does not depends on the rate, in spite of this rate depends on temperature.
- Controlled variables: Environment of the reaction, amount of catalyst, light exposure to the reactions are the controlled variables as it depends on the requirement of the amount of product.
Hence, hypothesis is as temperature increases rate of reaction also increases.

D. As acids are highly corrosive, so it's important to wear goggles, lab coat, chemical gloves and close-toed shoes to avoid from any accident during the experiment
Answer:
One mole of NaCl contains 6.022 x 1023 NaCl formula units.....
Since all of those percents add up to 100, you can just directly convert that to grams. So now you can use 2 grams H, 32.7 grams S, and 65.3 grams O. Use that info and convert that to moles for an answer of 2mol H, 1mol S, and 4mol O. In every empirical question you need to divide each quantity of moles by the lowest number. In this case, that number is one, so they stay the same, but it's important to remember that step. You're final chemical formula would be H2SO4 and the answer to your question would be that the subscript for oxygen is 4. Hope this helped!
