Which is correct about Water?
Water is an uncountable noun and is considered singular. So is 'is the correct tense.
The correct answer is Water is a nonpolar molecule. Water is a polar molecule: Water is a polar molecule. While the overall charge of the molecule is neutral, the orientation of the two positively charged hydrogens (+1 each) at one end and the negatively charged oxygen (-2) at the other end give it two poles.
Water possesses intermolecular hydrogen bonding in the condensed phase rather than intramolecular hydrogen bonding. Therefore statement (D) is incorrect.
In terms of location, it is "in the water", not "on the grass" or "in a tree" or "in the air" or "on a rock" or "on the cat's wrist". If you want to be precise, something "floating" is not "on the top of the water": it is partly below the surface (in the water) and partly above the surface (in the air).
"The total water in the lakes and rivers of the world remains constant or the total water under the ground remains constant or the total water in this season, oceans of the world remains constant or the total water of the world remains constant. So the answer is that if they are talking about Total War.
Answer and Explanation: The following is not true about water molecules: c) Water molecules form ionic bonds. Rather, water molecules form hydrogen bonds with each other due...
1 Answer. The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends.
Answer: D, The choice that is not a property of water is that its density as a solid is higher than its density as a liquid. Unlike most substances, solid water (ice) is less dense than liquid water. Key Takeaway: Water has numerous essential properties that are important biologically and in other aspects of life.
B. the water table is generally flat is the false statement.. Water table receives the water from surface that is filtered through soil, sediment and rocks. The source of water for water table is rain, irrigation and snow.
Water is a Polar Covalent Molecule
The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles - a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side).
Is ice more dense than liquid water?
The density of water is roughly 1 gram per milliliter but, this changes with temperature or if there are substances dissolved in it. Ice is less dense than liquid water which is why your ice cubes float in your glass.
water, a substance composed of the chemical elements hydrogen and oxygen and existing in gaseous, liquid, and solid states. It is one of the most plentiful and essential of compounds. A tasteless and odourless liquid at room temperature, it has the important ability to dissolve many other substances.
"Water" (singular form) is in the sense of an area or stretch of water (such as a river, lake or sea). Example: the path ran down to the water's edge. "Waters" (plural form) is in the sense of a body of water of a particular place. Example: the waters of Hudson Bay, the waters of the Andaman Islands.
Liquid water is found in bodies of water, such as an ocean, sea, lake, river, stream, canal, pond, or puddle. The majority of water on Earth is seawater. Water is also present in the atmosphere in solid, liquid, and vapor states.
The main sources of water are surface water, groundwater and rainwater.
About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. Water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in aquifers, and even in you and your dog.
Water is essential for life because: Water forms the major component of a living organism. It plays a vital role as all the metabolic processes required for growth and development requires a liquid medium. Most of the reactions occur when the substances are in the dissolved state.
Give me some water - means asking the person who has water, and you asking to give that water to you.
Should he have used "has" instead of "have"? The Associated Press Stylebook says "each" calls for a singular verb, so the speaker should have used "has." Webster's Dictionary of English Usage says, "The rule of thumb from the 18th century on has been that 'each' takes a singular verb.
There isn't any water in the glass.
But it is impossible to count water.
