How is a mass spectrum defined? A mass spectrum is an intensity vs. m/z (mass-to-charge ratio) plot representing a chemical analysis. Hence, the mass spectrum of a sample is a pattern representing the distribution of ions by mass (more correctly: mass-to-charge ratio) in a sample. What are three types of mass spectrometry? Types of Mass […]
Why is bronze not a chemical reaction?
Why is bronze not a chemical reaction? Creation of an alloy is not a chemical process as all that is happening is that heat is being applied to the metals to liquify them, then mixng them together. Does bronze last forever? So how long do they last? Ethan Darby of Trigard Memorials states “in the […]
What is the mass of silicon-30?
What is the mass of silicon-30? 29.9737702 Is it safe to bake in silicone pans? Silicone bakeware is heat-resistant and safe for the oven and freezer. It doesn’t change flavours or release odours that might affect food quality. It’s believed to have low toxicity and thermal stability. It’s also non-stick and easy to clean. Is […]
Is it rude to say I have no idea?
How does the electromagnetic spectrum work?
How does the electromagnetic spectrum work? Electromagnetic energy travels in waves and spans a broad spectrum from very long radio waves to very short gamma rays. The human eye can only detect only a small portion of this spectrum called visible light. A radio detects a different portion of the spectrum, and an x-ray machine […]
What was the first goal of the Human Genome Project?
What was the first goal of the Human Genome Project? The Human Genome Project was started in 1990 with the goal of sequencing and identifying all base pairs in the human genetic instruction set, finding the genetic roots of disease and then developing treatments. How will the Human Genome Project help us in the future? […]
What is the Debroglie wavelength associated with a ball of mass 100 gm Travelling at 50 m/s is?
What is the Debroglie wavelength associated with a ball of mass 100 gm Travelling at 50 m/s is? λ=(6.626×10-34kgm2s-1)(0.1kg)×(100ms-1)=6.626×10-35m. What is the de Broglie wavelength of a rifle with mass 11 g moving at a velocity of 950 m s? What is the de Broglie wavelength of a rifle bullet with mass 11 g moving […]
Is white light really white?
Is white light really white? White light is a mixture of all colors, in roughly equal proportions. White objects look white because they reflect back all the visible wavelengths of light that shine on them – so the light still looks white to us. What are the colors of white light? The spectrum of white […]
How much radiation emits from a phone?
How much radiation emits from a phone? The numbers refer to the rate of radiofrequency energy your body absorbs from the phone. The lower the number, the lower the radiation exposure. Most phones on the market fall between 0.35 and 1.59 watts per kilogram, which is the maximum level allowed by the U.S. government. Does […]
What are three ways heat is transferred?
What are three ways heat is transferred? Heat can be transferred in three ways: by conduction, by convection, and by radiation. Conduction is the transfer of energy from one molecule to another by direct contact. Convection is the movement of heat by a fluid such as water or air. Radiation is the transfer of heat […]
