How many hydrogen elements and oxygen elements are in a drop of water?
A drop of water typically consists of 2 hydrogen atoms and 1 oxygen atom. This is represented by the chemical formula H2O.
Why chlorine is used in the purification of water?
Chlorine is used in the purification of water because it is a powerful disinfectant that kills bacteria, viruses, and other harmful microorganisms present in water. It helps to ensure that the water is safe to drink by reducing the risk of waterborne diseases. Additionally, chlorine can also help to control algae and other organic matter in water sources.
The bonds that link many water molecules together to form a water drop are bonds.?
Hydrogen.
A certain public water supply contained 0.10 ppb of chloroform CHCl3 How many molecules of CHCl3 would be contained in a 050 mL drop of water?
To calculate the number of molecules of CHCl3 in a 0.050 mL drop of water, you first need to convert the concentration of CHCl3 from ppb to molecules/mL. Then, use Avogadro's number to convert molecules/mL to molecules in the drop. Finally, calculate the number of molecules in the drop by multiplying the concentration in molecules/mL by the volume of the drop in mL.
A drop of water has a volume of 0.05mL how many water molecules does it contain?
How big is a drop? "A drop" is not a precise measurement. It depends on a number of factors. If you measure how big the drops of water are you're talking about, (in millilitre) then you could figure out the number of molecules based on the fact that Avogadro's number of water molecules have a volume of about 18 milliliters. Avogadro's number is 6.022 * 1023 (particles) per mole One drop: average volume about 0.05 ml = 0.05 g Molar mass of water 18.01 g/mol Meaning: about 1.7*1021 molecules in a drop of water: don't start counting them!!
What microorganisms live in salt water?
Many microorganisms are found naturally in fresh and saltwater.
Why are Micro-organisms in Water?
Microorganisms are addapted to whatever environment there is. Many live in the water simply to sustain the fragile ecosysytem there.
What did you learn about pond water?
It is water in a ditch with many microorganisms in them.
Does freezing streile water?
Freezing sterile water will not kill any microorganisms that may be present in the water. Freezing can actually preserve these microorganisms until the water is thawed. To eliminate microorganisms, water needs to be sterilized through methods such as boiling or using chemical disinfectants.
What are the advantages of swamps?
There are many benefits of swamps. Swamps are home to many unique microorganisms, and many other creatures live in the swamp that are unable to live in other environments.
What organisms live billion years ago?
Many of these are microorganisms like bacteria and they first formed in the seas.
How many hydrogen atoms are in a drop of water?
Approx. 0,33.1018 hydrogen atoms for a drop of 1o microliters.
What is the disadvantages of microorganisms?
The disadvantage of microorganisms is that many of them cause disease.
What is disadvantages of microorganisms?
The disadvantage of microorganisms is that many of them cause disease.
Is this true or false neither fresh water nor salt water profide habitats for many living things?
False. Both fresh water and salt water provide habitats for a wide variety of living things, including plants, animals, and microorganisms. Many species have adapted to live in either freshwater or saltwater environments.
Do micro organisms grow in moist soil?
Yes, microorganisms can grow in moist soil. Moisture is a critical factor for the growth and survival of many microorganisms, as it provides the necessary environment for metabolic processes and reproduction. The presence of water in soil allows microorganisms to thrive and contribute to nutrient cycling and decomposition processes.
How many times can a drop of a drop of water go round the water cycle?
A drop of water can go through the water cycle an unlimited number of times since the water cycle is a continuous process of evaporation, condensation, and precipitation. This means that the same drop of water can be evaporated, form clouds, fall as precipitation, and return to the Earth's surface multiple times throughout the water cycle.
