How does electrostatic occur? Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged. The rubbing of certain materials against one another can transfer negative charges, or electrons. […]
What makes a real image?
What makes a real image? A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to diverge. Real images can be produced by concave mirrors and converging lenses, only if the object is placed further away from the mirror/lens than the focal point, and this real image is inverted. […]
What is easier for MG to do based on its valence electrons?
What is the symbol of cobalt?
What is the symbol of cobalt? Co What are the effects of cobalt on humans? Cobalt dust may cause an asthma-like disease with symptoms ranging from cough, shortness of breath and dyspnea to decreased pulmonary function, nodular fibrosis, permanent disability, and death. Exposure to cobalt may cause weight loss, dermatitis, and respiratory hypersensitivity. What is […]

How many valence electrons are present in the sodium atom? one valence electron How many valence electrons are present in sodium? Why does sodium have one valence electron? Sodium has one valence electron. The element has a full innermost electron shell of two electrons and a full shell of eight electrons in the next shell. […]
What is the most reliable way to identify a mineral?
What is the most reliable way to identify a mineral? The most reliable way to identify a mineral using color is the streak test. It is more reliable because even though the color of a specimen can vary its streak is usually the same. Which properties are used to identify minerals select 3 choices? Magnetism, […]
Which mineral test is shown in the image 2 points image showing minerals that have been rubbed against a white board leaving different colored lines on the board?
Which mineral test is shown in the image 2 points image showing minerals that have been rubbed against a white board leaving different colored lines on the board? Streak test is a method to determine what color would the mineral had if it’s being transformed into a powdered form. This test is being done by […]
Why do the two slits need to be small in order for an interference pattern to occur?
Why do the two slits need to be small in order for an interference pattern to occur? The very short wavelengths of visible light explain why interference effects are observed only in special circumstances—the spacing between the sources of the interfering light waves must be very small to separate regions of constructive and destructive interference. […]
Why does rain make me feel safe?
Why does rain make me feel safe? Studies have found that when rain sounds enters people’s brain, brain unconsciously relaxes and produces alpha waves, which are very close to the state of brain when human sleeps. Rain sound is generally between 0 and 20 kHz. It is not upsetting. On the contrary, this sound makes […]
Does helium go bad?
Does helium go bad? No, helium does not expire. You must close the valve tightly or helium will leak over time. Are Balloon Time tanks recyclable? What weight can helium lift? Helium atoms weigh less than the oxygen and nitrogen atoms in the air. Helium has a lifting force of about one gram per litre. […]
