How do you calculate a mix ratio? Divide 1 by the total number of parts (water + solution). For example, if your mix ratio is 8:1 or 8 parts water to 1 part solution, there are (8 + 1) or 9 parts. The mixing percentage is 11.1% (1 divided by 9). How do you calculate […]
What reaction produces O2?
What reaction produces O2? When manganese(IV) oxide is added to hydrogen peroxide, bubbles of oxygen are given off. To make oxygen in the laboratory, hydrogen peroxide is poured into a conical flask containing some manganese(IV) oxide. The gas produced is collected in an upside-down gas jar filled with water. What is the product of 2H2 […]
What is the principle of viscometer?
What is the principle of viscometer? These viscometers use the principle of ‘rotational viscometry’, i.e. their measurement of product viscosity is based upon immersing a specifically selected spindle within a sample of the product followed by measurement of the torque required to rotate the spindle at a set speed whilst immersed within the product sample […]
Why tidal energy is bad?
Why tidal energy is bad? Intermittent: Tidal energy can only be produce electricity during tidal surges, limiting electricity generation to 10 hours per day. Expensive: Technology for generating electricity from tidal energy is relatively new and not yet commercially profitable. Tidal power plants are also expensive to build and maintain. Why is tidal power not […]
What material absorbs sound waves?
What material absorbs sound waves? In general, soft, pliable, or porous materials (like cloths) serve as good acoustic insulators – absorbing most sound, whereas dense, hard, impenetrable materials (such as metals) reflect most. Is styrofoam a good sound blocker? Polystyrene foams such as Styrofoam can help muffle and reduce the presence of any noises from […]
What element has the strongest metallic bond?
What element has the strongest metallic bond? While in the case of ‘C’ valance shell has 3eā. Due to which ionization energy is high and it is most stable among all. Thus it forms strongest metallic bond. Which type of bonding is strongest? Covalent Bonds Which bond is stronger covalent or metallic? Covalent bond means […]
What is the major disadvantage of UV light as a disinfectant sterilant?
What is the major disadvantage of UV light as a disinfectant sterilant? Disadvantages of UV disinfection? UV light needs the right amount of energy to be effective. UV light is effective for microorganisms not for chemicals. Photochemical damage caused by UV may be repaired by some organisms. Is UVC air purifier safe? It’s questionable. The […]
How many chromosomes do 2 daughter cells have?
How many chromosomes do 2 daughter cells have? 30 chromosomes Are men with Klinefelter’s infertile? Klinefelter syndrome is a common genetic condition. Affected non-mosaic men are azoospermic and have been labelled as infertile. Despite reports that these men can have children using assisted reproduction techniques, it is not common practice in the UK to offer […]
Do any animals live in Lake Natron?
Do any animals live in Lake Natron? While it may be paradise for haloarchaea, many creatures can’t survive in such alkaline waters ā but animals whose bodies are adapted to such pH levels also inhabit the lake, meaning Lake Natron is far from barren. Flocks of flamingos, other birds and tilapia fish all call the […]
