What must occur in order for a chemical reaction to be specifically classified as endothermic? What must occur in order for a chemical reaction to be specifically classified as endothermic instead of exothermic? Energy is absorbed in the form of heat. Which statements best describes how a catalyst can speed up a chemical reaction? Explanation: […]
Why metamorphic rocks are hardest?
Why metamorphic rocks are hardest? Answer: Metamorphic rocks are almost always harder than sedimentary because they have gone many processe . They are generally as hard and sometimes harder than igneous rocks. They form the roots of many mountain chains and are exposed to the surface after the softer outer layers of rocks are eroded […]
Which best represents the law of conservation of mass?
Which best represents the law of conservation of mass? It is less than the mass of potassium chlorate. Which best represents the law of conservation of mass? mass of reactants = mass of products. Liquid 1 reacts with Liquid 2, producing a solid and a gas. Which best describes the law of conservation? The law […]
How many electrons must be transferred to a body to produce a charge of NC?
What is HF and HV?
What is a water cycle Why is it important?
What is a water cycle Why is it important? The water cycle is an extremely important process because it enables the availability of water for all living organisms and regulates weather patterns on our planet. If water didn’t naturally recycle itself, we would run out of clean water, which is essential to life. What is […]
Are stop lights timed?
Are stop lights timed? Types of Traffic Sensors. While some traffic lights operate strictly on a timed system that changes the light only at preset intervals, as technology has evolved, traffic control systems have become more advanced, allowing systems to more effectively manage traffic flow. Who turns first at a 4 way stop? First come, […]
Why is Ca2 a second messenger?
Why is Ca2 a second messenger? Calcium ion (Ca(2+)) plays an important role in stimulus-response reactions of cells as a second messenger. This is done by keeping cytoplasmic Ca(2+) concentration low at rest and by mobilizing Ca(2+) in response to stimulus, which in turn activates the cellular reaction. What is the first messenger that starts […]
Why is it important to protect non-human primates?
Why is it important to protect non-human primates? Primate conservation is therefore crucially important to maintain intact ecosystems and the many services these ecosystems provide to people, including clean and stable water sup- plies, prevention from floods and landslide, pollin- ation, stable micro-climates, and buffering of global warming (Wich et al. 2011). What are some […]
At what point is potential a minimum?
At what point is potential a minimum? When the angle between the dipole moment and electric field is zero then the potential energy of electric dipole is minimum. What is an example of electrical energy to kinetic energy? Electrical kinetic energy actually explains the transit of the electrical energy itself, electricity. For example, the electrical […]
