. Why are these alcohols important specially this time of pandemic? |
|
Answer» Explanation: Consuming alcohol will not destroy the virus, and its consumption is LIKELY to increase the health risks if a person becomes infected with the virus. Alcohol (at a concentration of at LEAST 60% by volume) works as a disinfectant on your SKIN, but it has no such effect within your system when ingested. Those withdrawals can lead to symptoms such as agitation, a rapid heartbeat, high BLOOD pressure and possibly even hallucinations. If that occurs, then trips to the hospital are a near-certainty, with some cases forcing patients to be placed into a MEDICALLY induced coma that requires intubation and ventilators. |

How to find acceleration? |
|
Answer» Answer: Acceleration (a) is the CHANGE in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to MEASURE how fast velocity changes in meters per second SQUARED (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and DIRECTION. |

calculate the formula unit of mass of 2nO K2CO given atomic masses of Zn=65u Na=23u K=39u C=12u and O=16u |
|
Answer» Formula unit mass is DEFINED as the sum of the atomic masses of all atoms that are present in a formula unit of the given compound. Atomic mass of Zn = 65u Atomic mass of NA = 23u Atomic mass of K = 39u Atomic mass of C = 12u Atomic mass of O = 16u Calculating the formula unit masses of the given compounds: ZNO = (65+16)u = 81u Na2O = [(2 x 23)+16]u = (46+16)u = 62u K2CO3 = [(2 x 39)+12+(3×16)] = (78+12+48)u = 138u Hence, the formula unit mass of ZnO is 81u, Na2O is 62u and K2CO3 is 138u |

Radioisotopes, are special chemical elements that are produced through the natural decay ofatoms. Exposure to radiation generally is considered harmful to the human body, but radioisotopes are highly valuable in medicine, particularly in the diagnosis and treatment of disease. Half-life is the time required for a quantity to reduce to half of its initial value. This term is commonly used to describe radioactive decay of atoms. Few Radioisotopes have short half-lives and decay before their emitted radioactivity can cause damage to the patient’s body.For example, if the half-life of a 50.0 gram sample is 3 years, then in 3 years only 25 grams would remain. During the next 3 years, 12.5 grams would remain and so on.Question 16:-Fluorine-18 is a radioactive isotope of fluorine that is used in medical imaging scans. It has a half-life of approximately 110 minutes. If a patient has a medical imaging scan using an injection of fluorine-18 at 9 am, at what time will there be less than 25% of the radioactive isotope in her body?a) 10 amb) 12 pmc) 1 pmd) 11 amQuestion 17:-A radioactive substance Technetium-99 is also used by physicians to examine blood flow to specific organs and assess organ function or bone growth. It has a very short half-life of about 6hours. The fraction of this material that would remain after 30 hours will be-a) 1/32b) 1/5c) 1/2d) 4/5 |

Answer» Examples to show that friction is a friend and a foe: Friction is friend: (i) Friction allows us to grip and catch different objects. (ii) It helps us to walk COMFORTABLY on the surface. (III) It helps to minimize the speed or to STOP the moving objects. (iv) It helps us to write on paper or blackboard. (v) The things do not move from their PLACES if we do not want to move, due to friction. Friction is foe: (i) Friction causes wear and tear in objects. (ii) It causes damage to the parts of machines. (iii) The machines or tools regular MAINTENANCE due to which a lot of money is wasted. (iv) It reduces the speed of moving objects so more force is required. (v) It does not allow the free movement of objects. |
