Three liquid substances of the same mass and have an S.G. of 1.50, 0.835 and 1.2 were being mixed to form a new compound. Estimate the resulting density. a. 1.1407g/cm3  b. 1.1121g/cm3 c. 1.1454g/cm3  d. 1.2232g/cm3

A new linear temperature scale, degrees Zunzol (°Z), is based on the freezing point and boiling point of a newly discovered compound zunzol. The freezing point of zunzol, -141.5 °C, is defined as 0 °Z, and the boiling point of zunzol, -24.8 °C, is defined as 100 °Z. What is the freezing point of water in degrees Zunzol? freezing point: Z. What is the boiling point of water in degrees Zunzol? boiling point: I. Z. TOOLS X10 64°F Clear 2:10 PM JENG 9/3/2021 F4 FZ F8 home end nser t delete 12

3. Carefully put an egg in a glass half filled with vinegar. Replace the vinegar on the second day. Place the covered glass with the vinegar and egg in a safe place for one week without disturbing it. After one week, pass a light through the egg using a flashlight. N.B. DO NOT BOIL AND EAT THE EGG. A. Results and observation. Equation: HC2H3O2 + CaCO3 calcium acetate + H20 + carbon dioxide B. Calculation: If 9.02 x 1024 particles of vinegar (HC2H3O2)HC2H3O2) is added to 16.5 moles of eggshell (CaCO3) and 6.35 moles g of calcium acetate is formed. What are the (a) theoretical yield, (b) actual yield and (c) percent yield

When a marble is dropped into a beaker of water, it sinks to the bottom. Which of the following is the best explanation? a. The surface area of the marble is not large enough to be held up by the surface tension of the water. b. The mass of the marble is greater than that of the water. c. The marble weighs more than an equivalent volume of the water. d. The force from dropping the marble breaks the surface tension of the water. e. The marble has greater mass and volume than the water. Justify your choice, and for choices you did not pick, explain what is wrong about them.
