Is 19 km/h wind strong? 10 to 19 km/h Weather wanes will move, leaves will rustle, and you’ll feel a breeze on your face. Situation normal. 20 to 29 km/h Strong enough to straighten flying flags and shake small tree branches. How much is 70 km in miles per hour? Convert 70 Kilometers per Hour […]
Is Br2 polar or nonpolar?
Is Br2 polar or nonpolar? So, Is Br2 Polar or Nonpolar? Br2 (Bromine) is nonpolar because, in this molecule, both bromine atoms have the same electronegativity due to which both atoms have equal charge distribution and results in a net-zero dipole moment. What type of molecule is AlCl3? Aluminum chloride is a chemical compound with […]
How can you speed up an exothermic reaction?
How can you speed up an exothermic reaction? Decrease the temperature in Exothermic reactions (Reactions that release energy, or become hot) Add a catalyst (A substance that reduces activation energy, speeding up the reaction) Increase the concentration of reactants. Increase the concentration of catalysts. Why is a match exothermic? – when Energy is released along […]
What are the four basic earth systems?
What are the four basic earth systems? Everything in Earth’s system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called “spheres.” Specifically, they are the “lithosphere” (land), “hydrosphere” (water), “biosphere” (living things), and “atmosphere” (air). Which is the largest system on earth? geosphere How […]

How do you explain observations?
How do you explain observations? Observation is the active acquisition of information from a primary source. In living beings, observation employs the senses. In science, observation can also involve the perception and recording of data via the use of scientific instruments. The term may also refer to any data collected during the scientific activity. What […]
How do I increase the resolution of my GC?
How do I increase the resolution of my GC? To improve the resolution of earlier eluting peaks, decrease the initial temperature or increase the initial hold time. Decreasing the initial temperature usually results in the largest resolution improvement, but analysis times are substantially increased (Figure 32a). What affects resolution in GC? Changes in resolution are […]
What are the dangers of DNA testing?
What are the dangers of DNA testing? People may feel angry, depressed, anxious, or guilty about their results. In some cases, genetic testing creates tension within a family because the results can reveal information about other family members in addition to the person who is tested. Is DNA testing worth it? DNA tests can give […]
