HI!!
Explanation:
The correct answer is A) they both must decide how to allocate resources. Based on the lesson, individuals and economies are similar because both must decide how to allocate resources.
Fat and soap are different substances. <span>One reason is that they have a different malleability. The Soap is very hard and sturdy. The fat is soft. Also, soap and fat are different because they had different smells. The soap had a refreshing smell and a soapy one and the fat smelled rubbery like Play-doh. Another reason why fat and soap are different substances is that they don’t dissolve the same in water and oil. Soap is soluble in water and shortening is not soluble in water. Soap is not soluble in oil and shortening is soluble in oil. In the water shortening did not become cloudy but soap did. When placed in oil, the shortening disappeared completely, while soap did not change at all.The melting point of the fat was 57.6 we could not find the melting point of the soap. The soaps melting point is higher than the water's boiling point. A property is something that describes an object and does not change. For example, the soap is white, where the fat is off white. Color is a property. Fat and soap are also different because they have different densities. The soap sank but the fat floated. The density of fat is about .88 g/ml and the density of soap is about 1.18 g/ml. </span><span>Fat and soap are not the same substances one reason is they have different properties.Malleability, hardness, solubility, melting point,color, and density are all properties. </span>A property is a characteristic of a substance that does not change. Different substances have different properties.<span> If they had the same properties, they would be the same substance, but, since they don’t, they are different substances.
Hope this helps :D</span>
Answer:
Explanation: So, the atomic number is the number of protons present in an atom. For example, Helium's atomic number is 2, meaning it only has 2 protons. In most cases, the number of nuetrons and protons are equal, so Helium (usually) has 2 protons and 2 nuetrons - this is the nucleus. The atomic mass, or mass per nucleon is the proton and nuetron added together, so the atomic mass of Helium is about 4. Therefore, on the periodic table, as the atomic number increases by 1, the atomic mass increases by about 2 (the atomic mass is an average so it's not exact).
