A strong central government could represent the nation to other countries. What was the main reason for the failure of the Articles of Confederation? […]

Are sections of DNA that code for specific traits? Gene What is a section of DNA that determines a trait? These sections of DNA th at contain information that determine your physical features are called genes. Since you have two pairs of chromosomes, you also have two pairs of genes, one from your fath er […]

What is the standard cell potential of galvanic cell? The voltmeter shows that the standard cell potential of a galvanic cell consisting of a SHE and a Zn/Zn2+ couple is E°cell = 0.76 V. Is nickel an anode or cathode? The nickel is the anode—the site of oxidation where nickel ions flow into solution and […]

What is partial pressure and how is it calculated? Partial pressures are determined by the mole fraction of the gas in the mixture, thus there are no specific values for gases. For example, if a mixture contains 1 mole of gas A and 2 moles of gas B and the total pressure is 3 atm. […]

Why does hot water freeze faster than cold water explain? Evaporation. One explanation of the effect is that as the hot water cools, it loses mass to evaporation. With less mass, the liquid has to lose less heat to cool, and so it cools faster. With this explanation, the hot water freezes first, but only […]

When equal volume of HCl and NaOH are mixed and the pH of resulting solution is checked with pH paper the Colour of pH paper is? When equal volumes of hydrochloric acid (strong acid) and sodium hydroxide (strong base) solution of same concentration are mixed, the result is salt and water. This is a neutralisation […]

What is the average speed of gas particles at room temperature? about 500 m/sec How is the average velocity of the gas molecules related to temperature? The speed of the molecules in a gas is proportional to the temperature and is inversely proportional to molar mass of the gas. In other words, as the temperature […]

Which rocks have remains of plants and animals? “Fossils are remains of organisms, both plants and animals which has been preserved within the sedimentary rock beds, under favourable geologic conditions.” The study of plant fossils is also helpful in locating the occurrence of coal, oil and gas deposits in the earth. What type of sedimentary […]

What is the molar solubility in water of Ag2CrO4? The molar solubility of Ag2CrO4 in water is 6.5 x 10-5 M. What will be the solubility of AgCl? Answers. The solubility of silver chloride, AgCl, is 1.26 x 10-5 M at 25 °C. The solubility of barium fluoride, BaF2, is 3.14 x 10-3 M at […]

What happens to prices with government regulations? Often, complying with regulations is costly for firms, and these higher costs may in turn drive up prices for consumers. Higher prices caused by regulatory growth are unlikely to affect all consumers equally. The data show evidence of a statistically significant relationship between regulation and increased prices. What […]
