How many ppm (by weight, mg/kg) of tungsten are present in a 28.6-gram light bulb with a 0.178-gram filament containing 83.7% tungsten? How many mg are contained in a 433 kg sample? How many grams of Mg will be needed to make 5.000 kg MgCl_2?
Depending on the amount of solute(s), solutions can be classified as undersaturated, saturated, or oversaturated/supersaturated. The concentration of solutes can also alter the properties of a solution, such as, its boiling point and freezing temperature (which tend to greatly diff...
Calcium hardness should be between 150 and 250 ppm. If either of these levels is too high or too low, it can make your hot tub's water cloudy. After you've adjusted the pH levels, it's a good idea to do a partial water change to remove the hot tub chemicals from the water. This...
Preceden is a free, lightweight project timeline maker that works fast to make colorful timelines. This web-based timeline tool allows you to build and share a timeline. You can create one timeline with up to 10 events on the free version, but payment is required to create more than that....
You may also use a disinfectant, such as a hypochlorous acid-based solution (50-80 ppm) or an alcohol-based solution (over 70% ethanol or isopropyl alcohol). Apply these solutions to the microfiber cloth, not directly to your device. ...
While Word isn’tproject management software, it’s a tool that you might need to use at some point to create project reports or other types of documents. Because of this, knowing how to make a Gantt chart in Word can be helpful. ...
Adjusting pH takes less than 5 minutes, and your plants will reward you. Think of it like a supplement to make your cannabis grow faster and healthier! Table of Contents Introduction: How Does pH Prevent Nutrient Deficiencies? What’s the Correct pH?
The fact that PPM is a dimensionless measure is important. You have to make sure that the way you're measuring both the substance you're interested in and what it's diluted in is the same. So if you have a volume of water with something dissolved in it, you'll either need to use ...
The core idea behind any system should be to: make work visible, identify bottlenecks, and ultimately improve efficiency. However, when dealing with multiple projects, it is necessary to integrate everything to ensure a clear overview and better organization. To achieve this, you may consider usin...
flow system, as it moves the solution to the grow tray. However, unlike an ebb-and-flow system that floods the grow tray, then totally drains it, NFT systems have a constant flow of a thin layer, or film, of nutrient solution. This means the roots are in constant contact with the ...
