QUESTION 11 Consider the following balanced chemical equation for the single replacement reaction of calcium metal with aqueous HCl to form calcium chloride and hydrogen
gas.
Ca(s) + 2HCl(aq) -> CaCl2(aq) + H268)
How many mL of 3.75 M HCl are required to react with 1.21 g of calcium?

The nucleus inside an atom consists of positively-charged  protons  and neutrally-charged  neutrons. a  proton  is a subatomic particle with a positive electric charge. allprotons  are identical.

Ibelieve it is b. proton.hope my answer has you : )

In order to improve results, many different steps can be taken into account. 1) using more precise scales and thermometers is always something that should be considered as being precise means that you are more exact with your answer.2) increasing the sample size should also be considered, if you have a bigger sample size you are able to determine if your results are accurate as well as if there are any variables that should be taken into account plus it assists in the statistical analysis and produces overall better data3) using better handwriting is also a plus, along with organizing the data properly so that others are also able to read the results and even redo the experiment in the future if it is needed.
