Whether the rate of the emission of radiations by uranium after purification is same, less or more than 5000 counts per minute is to be stated. The explanation for the corresponding answer is to be stated. Concept introduction: Any atom which has unstable nucleus due to the presence of more than 1.1 to 1.5 neutron to proton ratio value emit harmful radiations to give more stable fragment and these elements are known as radioactive elements. Radioactivity of any element is entirely dependent upon the type of nucleus present in the atom of that element known as nuclear chemical property.

Choosing reagents and conditions for acetal formation or hydrolysis 0/5 A student proposes the transformation below in one step of an organic synthesis. There may be one or more products missing from the right-hand side, but there are no reagents missing from the left-hand side. There may also be catalysts, small inorganic reagents, and other important reaction conditions missing from the arrow. • Is the student's transformation possible? If not, check the box under the drawing area. If the student's transformation is possible, then complete the reaction by adding any missing products to the right-hand side, and adding required catalysts, inorganic reagents, or other important reaction conditions above and below the arrow. • You do not need to balance the reaction, but be sure every important organic reactant or product is shown. + This transformation can't be done in one step. 5 I H Autumn alo 值 Ar B

A block of copper of mass 2.00kg(cp = 0.3851 .K) and g temperature 0°C is introduced into an insulated container in which there is 1.00molH, O(g) at 100°C and 1.00 2 atm. Note that C P = 4.184. K for liquid water, and g that A H = 2260 for water. vap g Assuming all the steam is condensed to water, and that the pressure remains constant: (a) What will be the final temperature of the system? (b) What is the heat transferred from the water to the copper? (c) What is the entropy change of the water, the copper, and the total system?

Identify the missing organic reactants in the following reaction: H+ X + Y OH H+ O O Note: This chemical equation only focuses on the important organic molecules in the reaction. Additional inorganic or small-molecule reactants or products (like H₂O) are not shown. In the drawing area below, draw the skeletal ("line") structures of the missing organic reactants X and Y.
