Is co2 an ionic compound? No, CO2 is not an ionic compound. As per the definition, an ionic compound is a compound that is mostly formed between a metal atom and a non-metal atom. Meanwhile, CO2 is a compound that is formed between two non-metal atoms (carbon and oxygen) thus giving it a covalent nature. […]

Can I get rabies from touching a dead bat? Bats with rabies are often disoriented, increasing the likelihood that they end up inside a dwelling by accident. If you find yourself in close proximity to a bat, dead or alive, do not touch, hit or destroy so the bat’s brain can be preserved for rabies […]

What is the relationship between valence electrons and ionic charge? When forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge. What happens […]

What is the formula for change in velocity? The change in velocity is also known as accel…” Yes. The change in velocity is also known as acceleration multiplied by the time. So, v=a*t. What is the simplest type of motion? The simplest form of motion is the motion in a straight line. The distance and […]

How do you calculate drag force in air? For larger objects (such as a baseball) moving at a velocity v in air, the drag force is given by FD=12CρAv2 F D = 1 2 C ρ A v 2 , where C is the drag coefficient (typical values are given in Table 1), A is […]

What is reflective mode? Reflection mode: In reflection mode, an ultrasonic transmitter emits a short burst of sound in a particular direction. The pulse bounces off a target and returns to the receiver after a time interval. The receiver records the length of this time interval and calculates the distance traveled based on the speed […]

What are the 3 types of diffusion? 1 Answer. Simple diffusion, osmosis and facilitated diffusion. Why do substances move in and out of cells? Substances move in and out of cells by diffusion down a concentration gradient, through a partially permeable membrane. The efficiency of movement of substances in and out of a cell is […]

What are the 3 main types of wind energy? There are three major types of wind energy. Utility-Scale Wind. This defines wind turbines that range in size from 100 kilowatts to several megawatts, where electricity is supplied to the power grid and distributed to the end user by electric utilities or power operators. Offshore Wind. […]

What are physical fitness tests? A physical fitness test may include a repetition maximum of strength-based exercises, like squats or bench presses, to assess muscular strength. It may also involve performing exercises, like bodyweight squats, until exhaustion, which tests muscular endurance. What are the 7 components of skill related fitness? There are six skill-related fitness […]

What is silver mostly used for? It is used for jewellery and silver tableware, where appearance is important. Silver is used to make mirrors, as it is the best reflector of visible light known, although it does tarnish with time. It is also used in dental alloys, solder and brazing alloys, electrical contacts and batteries. […]
