Answer : Gaseous water molecules condense when they cooled. Liquid water molecules evaporate when they heated.
Explanation :
Condensation : It is a process in which a phase changes from gaseous state to liquid state. This process occurs when the water molecules in the air cool down and they join together to form liquid water.
Evaporation : It is a process in which a phase changes from liquid state to gaseous state. This process occurs when the water is heated, the molecules in the water move and vibrate quickly that they escape into the atmosphere as water vapor.
Answer:
You need to add 3 100 pound bags of Parkerâs Premium Starter and 5 100 pound bags of Vigoro Ultra Turf fertilizer
Explanation:
You can obtain 3 equations. One for each compound:
For N:
177 pounds = 29x + 18y <em>(1) </em>
<em>-</em><em>Where x are bags of Vigoro Ultra Turf fertilizer</em><em> </em><em>and y are bags of </em>Parkerâs Premium Starte-
For P₂O₅:
134 pounds = 3x + 25y <em>(2)</em>
For K₂O:
42 pounds = 4x + 6y <em>(3)</em>
Replacing (1) in (2):
134 = (531/29 - 54y/29) + 25y
3355/29 = 671y/29
<em>y = 5 bags</em>
Thus,
<em>x = 3 bags</em>
You can replace in each equation to prove that this is the right result.
I hope it helps!

Answer:
The titration process has quite a few real-world uses, including key roles in the food industry and medical community. The titration process is essentially an analytical technique, as it is used to determine a chemical or physical property of a chemical substance, element, or mixture (such as food). Specifically in the food industry, it is used to allow food manufactuers to determine the quantity of a reactant in a sample. To provide an example, it can be used to find the specific amount of stuff that is usually labeled on the nutrition label, such as sugar, salt, protein, calcium, vitamin C, etc. As for the medical world, pharamcists typically use this process to get the proper mix when compounding medicines. It is used to get the necessary proportions in intravenous drips.
Answer:
Explanation:
Hello,
In this case, the undergoing chemical reaction is shown below:
Thus, we obtain 0.0471 g of lead (II) sulfate, the iodide ions in the original solution are computed below by stoichiometry, taking into account that into 1 mole of lead (II) iodide there are 2 moles of iodide ions:
Best regards.
B. People can use additional conservation tactics, like sometimes bicycling.
Explanation:
The use of bicycle to cover short distances would be good change in change in behavior that would enhance the conservational tactics in using fossil fuels.
Most hybrid cars still use gasoline. Although they have dualized energy sources.
- Driving hybrid cars more often will not curb the conservation drive for fossil fuel. It will increase more demand for it.
- Driving separate hybrid cars will not solve conservation issue of fossil fuels.
- Driving the car more is no efficient way to curb the reliance on fossil fuels.
The use of bicycles to cover maybe short distances will be a good approach to conserving more fossil fuels.
