How many types of indicators are there? Types of Indicators Artificial and Natural indicators are the two types of Chemical indicators. Litmus, red cabbage, turmeric, china rose are a number of the present indicators around us. What is another type of indicator? An indicator prepared from natural substances is known as natural indicator. Examples are […]
What is full form of ch2?
What is full form of ch2? Alternative Title: ethene. Ethylene (H2C=CH2), the simplest of the organic compounds known as alkenes, which contain carbon-carbon double bonds. It is a colourless, flammable gas having a sweet taste and odour. Why is ch2cl2 called methylene chloride? It is named like methylene dichloride(Cl-CH2-Cl) because of having the -CH2- group […]
What are two examples of sustainable resources?
What are two examples of sustainable resources? Examples of Sustainable Development Wind Energy. Solar Energy. Crop Rotation. Water efficient fixtures. Green Spaces. How a city can be sustainable? This means the main ways cities can become greener are to: Reduce the amount of energy and resources used through improving the efficiency of systems, for example […]
How is energy conserved in an electric motor Class 10?
How is energy conserved in an electric motor Class 10? The faster the wire is moving, the greater this “back EMF” becomes. When the back EMF equals the source voltage, the current through the wire goes to zero (in the ideal case) and the motor can revolve no faster. What is the working principle of […]
What happens if you build a house without a foundation?
What happens if you build a house without a foundation? Although a building may be able to support the downward thrust of its load without a foundation, it’s the sideways motion that creates the problem. As the ground changes temperature with the seasons, it expands and contracts, causing instabilities that make the building lurch. What […]
Can you use PEX for underground water line?
Can you use PEX for underground water line? In slab and underground Some plumbing contractors may be surprised to know that PEX is approved for use in underground as well as in-slab applications. What type of PEX is best for underground? Although an unbroken line of PEX would be ideal, dezincification-resistant brass PEX fittings or […]
Can photons hit each other?
Can photons hit each other? Since light itself does not have electric charge, one photon cannot directly interact with another photon. Instead, they just pass right through each other without being affected. A photon can spontaneously degenerate into a particle with mass and its antiparticle in a process known as pair production. Can you stop […]
Is ammonium hydroxide harmful to humans?
Is ammonium hydroxide harmful to humans? contact can severely irritate and burn the skin and eyes leading to eye damage. ► Exposure can irritate the eyes, nose and throat. ► Inhaling Ammonium Hydroxide can irritate the lungs. Higher exposures may cause a build-up of fluid in the lungs (pulmonary edema), a medical emergency. Is ammonium […]
Which fuel has the highest density?
Which fuel has the highest density? Liquid hydrocarbons (fuels such as gasoline, diesel and kerosene) are today the most dense way known to economically store and transport chemical energy at a large scale (1 kg of diesel fuel burns with the oxygen contained in ≈15 kg of air). What is density in petrol pump? As […]
What factor has the greatest influence on blood flow?
What factor has the greatest influence on blood flow? The three most important factors affecting resistance are blood viscosity, vessel length and vessel diameter and are each considered below. Blood viscosity is the thickness of fluids that affects their ability to flow. What are the four main factors that influence blood pressure? What are the […]
