A general formula of an acid always start with H or the hydronium ion. It has to end with an anion. As acids, these compounds are named starting with the prefix "hydro-," then adding the first syllable of the anion, then the suffix "-ic." Hope this answers the question.

the pressure would be 292, did i calculate that right?
Answer:
Second option
Explanation:
We started using fossil fuels which are the main cause of climate change
Answer:
The new volume of the balloon will be 6046.28 L
Explanation:
Initial pressure (P1) = 99 kpa
initial volume (V1) = 3000 L
Initial temperature = 39 C = 39 + 273 = 312 K
Final pressure (P2) = 45.5 kpa
Final temperature = 16 C = 16 +273 = 289K
Final volume = ????
To calculate the final volume using the general gas equation
P1 V1 / T1 = P2 V2 / T2
make V2 the subject of the formular
V2 = 99000 ×3000× 289 / 45500×312
V2 = 85833000 /14196
V2 = 6046.28 litres
The substances' sodium (Na), oxygen (O2), and sodium oxide (Na2O) participate in this chemical reaction. 4Na + O2 = 2Na2O is the reaction between Na and O2. The suitable sentence is Sodium oxide is created by the chemical reaction.
<h3>What is chemical reaction ?</h3>
A chemical reaction is a process that converts one or more substances, known as reactants, into one or more different substances, known as products. Chemical elements or compounds are examples of substances.
Because Na and O are not balanced, the balanced equation by hit and trial will be: 4Na+O2Na2O.
A chemical reaction occurs when two or more compounds or substances undergo chemical transformation to form new compounds or substances. Chemical equations express chemical reactions using symbols and chemical formulas of the compounds involved.
Thus, option B is correct.
