42. What volume of gold is equal in mass to a piece of copper having a volume of 125 cm3? Use Conversion Factors

How many picometers are in 100. yards?

Hello, I'm having difficulties to answer the chemistry problem. Can you please help me with all the parts? I really need help. Also, I need to be prepared for the exam. Please I need help with all the parts a,b,c,d. 7. A 4.82g sample of iron is heated to 84.3 C. A 1.25 g sample of gold is heated to 95.1 C. Both of these metals are added to 9.47 g of cold water that is initally at 14.5 C. a) From the first law of thermodynamics, what is the equation relating the sum of heats of two components?   b) Algebraically substitute in the specific heat capacites for the metal and water, the masses of the samples, and the temperature change (see problem 7.)   c) Solve the algebraic problem (b) for the Tp the final temperature of water.   d) Determine the final temperature of the metals in water. Hint: it's the same for all three components.

6. Which length is the longest? A) 12 m B) 12,000 mm C) 12,000 nm D) 12,000 cm E) 0012 km O b O c d. e

If you had 225 grams of water, what volume would that sample of water occupy? (use your average density you stated above.)

What is a disadvantage of using scientific notation?

write each in standard scientific notation a. 1/1033 b. 1/105 c. 1/10-7 d. 1/0.0002 e. 1/3,093,000 f. 1/10-4 g.1/109 h. 1/0.000015

QUESTION 2 Which of the following statements best describes the purpose of performing experiments? OA. Experiments are designed to produce unexplainable results. B. Experiments attempt to produce other observations that support or refute a theory or hypothesis. OC. None of the answers are correct. O D. Experiments can be replaced by logical reasoning based on the known facts. OE. Experiments are designed to produce the results predicted by a theory or hypothesis.

The Scientific Method Group of answer choices isn't used much in modern chemistry. is a strict set of rules and procedures that lead to inarguable fact is based on continued observation and experiment is just a theory
