Wearing sunglasses is not a response to an internal stimuli. It is a voluntary action instead of an involuntary one.
Answer:
<h2>It'll float</h2><h2>Less than 1g/cm3 it'll float in water </h2>
1 atm = 760mmHg
754.3 mmHg / 760 mmHg * 1atm = 0.99 atm
760 mmHg = 101.3 KPa
754.3 mmHg/ 760mmHg *101.3 KPa = 100.54 KPa
Hope this helps!
A- and H3O+ interact, causing A-'s concentration to drop and [HA] to rise. As a result, the [NaA]/[HA] ratio declines. Because of the base content, the buffer's pH will be more acidic. The concentration of the acid, HA, has increased while A- has decreased.
What is Acid?
Any material that when dissolved in water has an acidic taste, can alter the colour of some indicators (such as reddening blue litmus paper), can react with some metals (such as iron) to release hydrogen, can combine with bases to produce salts, and can accelerate some chemical reactions (acid catalysis). Acids are examples of organic chemicals that belong to the carboxylic acid, sulfonic acid, and phenol groups as well as the inorganic substances known as the mineral acids, such as sulfuric, nitric, hydrochloric, and phosphoric acids. These chemicals contain one or more hydrogen atoms, which are discharged as positively charged hydrogen ions when they are in solution.
