Answer the following question given this paragraph: Solutions of Liquids in Liquids We know that some liquids mix with each other in all proportions; in other words, they have infinite mutual solubility and are said to be miscible. Ethanol, sulfuric acid, and ethylene glycol (popular for use as antifreeze, pictured in Figure 11.14) are examples of liquids that are completely miscible with water. Two-cycle motor oil is miscible with gasoline. Q: Liquids that mix with each other in all proportions are said to be miscible, maning they have infinite mutual what? Choices: - viscosity - insolubility - salinity - solubility A:
solubility
Answer the following question given this paragraph: Q: Green algae and land plants are closely what? Choices: - unrelated - foreign - different - related A:
related
Q: Answer the following question given this paragraph: Energy in a body of water can be gained or lost depending on conditions. When water is heated above a certain temperature steam is generated. The increase in heat energy creates a higher level of disorder in the water molecules as they boil off and leave the liquid. Q: What do you need to do to water to make it steam? Choices: - freeze it - stir it - cool it - heat it A:
A: heat it
Question: Answer the following question given this paragraph: Note the Pattern Few binary molecular compounds of nitrogen are formed by the direct reaction of the elements. At elevated temperatures, nitrogen reacts with highly electropositive metals to formionic nitrides, such as Li3N and Ca3N2. These compounds consist of ionic lattices formed by M n+ and N3 ions. Just as boron forms interstitial borides and carbon forms interstitial carbides, with less electropositive metals nitrogen forms a range ofinterstitial nitrides, in which nitrogen occupies holes in a close-packed metallic structure. Like the interstitial carbides and borides, these substances are typically very hard, high-melting materials that have metallic luster and conductivity. Nitrogen also reacts with semimetals at very high temperatures to produce covalent nitrides, such as Si3N4 and BN, which are solids with extended covalent network structures similar to those of graphite or diamond. Consequently, they are usually high melting and chemically inert materials. Ammonia (NH3) is one of the few thermodynamically stable binary compounds of nitrogen with a nonmetal. It is not flammable in air, but it burns in an O2 atmosphere: Equation 22.30. Q: What (nh3) is one of the few thermodynamically stable binary compounds of nitrogen with a nonmetal? Choices: - liquid nitrogen - acetic acid - nitrous oxide - ammonia A:
Answer: ammonia
*Question*
Answer the following question given this paragraph: Below the topsoil is the "B" horizon. This is also called the subsoil . Soluble minerals and clays accumulate in the subsoil. Because it has less organic material, this layer is lighter brown in color than topsoil. It also holds more water due to the presence of iron and clay. There is less organic material in this layer. Q: Soluble minerals and clays accumulate in what soil layer, allowing it to hold more water? Choices: - silt - subsurface - topsoil - subsoil A:
**Answer**
subsoil
Answer the following question given this paragraph: Blood enters the kidney through the renal artery , which branches into capillaries. When blood passes through capillaries of the glomerulus of a nephron, blood pressure forces some of the water and dissolved substances in the blood to cross the capillary walls into Bowman's capsule . Q: Blood enters the kidney through the which artery? Choices: - cardiac artery - vas deferens - jugular - renal artery A:
renal artery
