I would go with choice A) because today u don't just touch acid when u feel like it because the chemicals can burn your skin off to the bone itself and even animals.

Answer:
When molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide. In this oxidation, a molecule of hydrogen gas is ionized to two electrons and two protons
Answer:
QUALITATIVE INTERVIEWING IS MOST USEFUL FOR:
* Evaluating programs that are aimed at individualized outcomes
* Capturing and describing program processes
* Exploring individual differences between participants' experiences and outcomes
* Evaluating programs that are seen as dynamic or evolving
* Understanding the meaning of a program to its participants
* Documenting variations in program implementation at different sites
QUALITATIVE INTERVIEWING IS NOT AS USEFUL FOR:
* Evaluating programs that emphasize common outcomes for all participants
* Measuring specific, predetermined effects of a program on participants
* In impact evaluations, deciding whether your intervention caused changes or effects in participants (since determining causality requires more controlled conditions)
Explanation:
An interview in qualitative research is a conversation where questions are asked to elicit information. The interviewer is usually a professional or paid researcher, sometimes trained, who poses questions to the interviewee, in an alternating series of usually brief questions and answers.
Answer:
Water is a covalent compound.
Explanation:
covalent compounds are individual molecules characterized by the sharing of electrons between two or more atoms. Two atoms with similar electronegativity will not exchange an electron from their outermost shell; the atoms instead share electrons so that their valence electron shell is filled.
Example:
Examples of compounds that contain only covalent bonds are methane (CH4), carbon monoxide (CO), Water (H2O) and iodine monobromide (IBr).
Properties:
1. At room temperature and normal atmospheric pressure, covalent compounds may exist as a solid, a liquid, or a gas.
2. Covalent compounds do not exhibit any electrical conductivity, either in pure form or when dissolved in water.
3. Covalent compounds have lower melting and boiling points.
