<h3><u>Answer;</u></h3>
New tire pressure = 214.286 kPa
<h3><u>Explanation;</u></h3>
According to Boyle's Law the volume of a fixed mass of a gas is inversely proportional to pressure at constant temperature.
P α V, and PV = Constant
Therefore;
P1V1 = P2V2, where P1 is the initial pressure, V1 is the initial volume , P2 is the new pressure and V2 is the new volume.
P2 = P1V1/V2
= (300 kPa × 30 L)/ 42 L
<u>= 214.286 kPa</u>
1. Fact: A dead organism is still an organic being.
Evidence: Non-living things differentiate from living beings due to differences in organic and non-organic chemical compounds. On top of this, non-living things were never alive in the first place.
2. Fact: The Linnaeus system, although still recognized as the perfect class system, has changed.
Evidence: Initially, Kingdom was the highest class in the system; however, later on, scientists introduced a class above this- the Domain.
3. Fact: The tiger and goldfish are not closely related.
Evidence: Although all living things share common ancestors from billions of years ago, they branched off and continued to do so since then. The only relation these two organisms share is distant DNA patterns.
4. An organism's kingdom is no longer only based on physical appearance.
Evidence: Although before the rise of genetics and evolutionary sciences this may have been the case, it isn't anymore. We now have the ability to analyze DNA, as well as actually pick apart what makes the organism what it is.
5. Mammals are indeed in the same domain as plants.
Evidence: All plants, fungi, protists, and animals posses eukaryotic cells; therefore placing them in the same domain.
Copper is a mineral and an element essential to our everyday lives. It is a major industrial metal because of its high ductility, malleability, thermal and electrical conductivity and resistance to corrosion. It is an essential nutrient in our daily diet. And, its antimicrobial property is becoming increasingly important to the prevention of infection. It ranks third after iron and aluminum in terms of quantities consumed in the USA.
The answer is highly soluble
<h3>How does sodium hydroxide dissolve in water?</h3>
When hydroxide (NaOH) dissolved in water, it divides into positively and negatively charged sodium ions (cations) and hydroxide ions (anions). These ions move freely and independently in water, while cations prefer to be surrounded more closely by anions and vice versa.
Although sodium hydroxide is more soluble in hot than in cold water, the process of dissolving sodium hydroxide in water is exothermic.
The unknown compound's insolubility in water might be attributed to its big hydrocarbon group. Because it is dissolved in 5% Naoh, its substituent may be acidic because the interaction with NaOH produces an anion that is soluble in aqueous solution.
