Weegy: This is true. User: What is the mass of 1.0 x 10-3 mole of Zn? Weegy: The answer is 5 User: How would Mg change to gain a noble gas structure? Weegy: For Mg to attain a pseud noble gas formation it must lose two electrons, becoming the ion Mg2+ User: Based upon the ion charge of the following polyatomic ions, predict the formula for the following compounds. sulfate = SO4 -2 phosphate = PO4 -3 hydroxide = OH- sodium hydroxide (More)

Weegy: According to periodic table, HALOGENS has seven valence electrons. User: A theory which repeatedly fails to confirm the expected predictions after extensive research: probably needs to be modified probably is incorrect requires more research time should be maintained indefinitely Weegy: probably needs to be modified User: The definition of volume is: Weegy: Volume is the amount of 3-dimensional space an object occupies. User: Drawing a conclusion derived from knowledge of an established principle is called deductive reasoning. True False Weegy: Drawing a conclusion derived from knowledge of an established principle is called deductive reasoning. TRUE. User: The three aspects of the measuring process are units, systems, and instruments. True False Weegy: True, The three aspects of the measuring process are units, systems, and instruments. User: A student is asked to convert measurements from liters to milliliters and from milliliters to liters. His answers are shown in bold in the choices shown below. On which choice did he make a mistake? Weegy: 3L = 3000 mL User: A student is asked to convert measurements from liters to milliliters and from milliliters to liters. His answers are shown in bold in the choices shown below. On which choice did he make a mistake? 0.402 L = 402 mL 0.0202 L = 20.2 mL 3.6 L = 360 mL 11.1 L = 11,100 mL Weegy: 3.6 L =360 mL is False.

User: When writing 6,020,000 in scientific notation, it is correctly written as: Weegy: When writing 6,020,000 in scientific notation, it is correctly written as 6.02 x 10^6. User: A hypothesis which appears to be verified by multiple experiments and/or ... (More)

Weegy: Solids and liquids have both mass and volume, but a gas has only mass. FALSE. All matter has a volume, since it takes up space. The main difference between a gas and a solid or a liquid is that the volume a gas takes up can be changed. Solids and liquids are not compressible; gases are. User: If you move an object from the base of a mountain to the top of the mountain: mass and weight remain constant only mass remains constant only weight remains constant both mass and weight will change (More)
