How do you identify an ion in a compound?
How do you identify an ion in a compound? To find the formula of an ionic compound, first identify the cation and write down its symbol and charge. Then, identify the anion and write down its symbol and charge. Finally, combine the two ions to form an electrically neutral compound. What must be included in […]

What is an atomic number for dummies?
What are the three types of radiometric dating?
What are the three types of radiometric dating? Among the best-known techniques are radiocarbon dating, potassium–argon dating and uranium–lead dating. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change. How far back can radiometric dating go? C (the […]
Is there a difference between a silencer and a repressor?
Is there a difference between a silencer and a repressor? In genetics, a silencer is a DNA sequence capable of binding transcription regulation factors, called repressors. DNA contains genes and provides the template to produce messenger RNA (mRNA). Thus, silencers prevent genes from being expressed as proteins. … What is the difference between an inducer […]
Does WIFI use radio waves?
Does WIFI use radio waves? Wi-Fi uses radio waves to transmit information between your device and a router via frequencies. Two radio-wave frequencies can be used, depending on the amount of data being sent: 2.4 gigahertz and 5 gigahertz. The two Wi-Fi frequencies are split into multiple channels so as to prevent high traffic and […]

Is pressure related to flow rate?
Is pressure related to flow rate? Higher pressure differences will drive greater flow rates. The pressure gradient establishes the direction of flow. Flow is different than velocity. What does flow rate depend on? To put this relationship into words: At a given temperature, flow rate through a tube or pipe is inversely proportional to the […]
What causes diffusion of oxygen into a plant cell?
What causes diffusion of oxygen into a plant cell? In plant cells the contents are surrounded by a cell membrane and a cell wall. Substances such as oxygen and carbon dioxide pass through these by diffusion. Plants use up carbon dioxide during photosynthesis. This causes oxygen to diffuse out of the leaf into the air. […]
