Answer:
is a well-sustantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.such fact- supported theories are not "guesses" but reliable accounts of the real worlds.
The pressure in the flask is 3.4 atm.
<em>pV</em> = <em>nRT
</em>
<em>T</em> = (20 + 273.15) K = 293.15 K
<em>p</em> = (<em>nRT</em>)/<em>V</em> = (1.4 mol × 0.082 06 L·atm·K⁻¹mol⁻¹ × 293.15 K)/10 L = 3.4 atm
Answer:
C. A metal ion takes the place of the hydrogen of an acid
Explanation:
When an acid react with base neutralization reaction take place.
During neutralization reaction water and salt are formed.
For example;
Base sodium hydroxide react with hydrochloric acid and form sodium chloride and water.
The sodium hydroxide consist of sodium metal ion in the form of Na⁺ and OH⁻. when it react with acid hydrogen atom of acid replace by sodium metal and react with anion of acid and form salt called sodium chloride.
Chemical equation:
NaOH + HCl → NaCl + H₂O
