Explanation:
compound is already together use your brain man you take multiple things. to make lemonade aka a mixture of powder and water cmon man u gotta think about it logically
think about like this a bartebder asjs you what drink your having what is he going to do next ? hes going to make the drink so you can have another right? yha
observe what happens next
the bartender grabs a cup and goes to the ice and scoops it up he takes a bottle of vodka and puts it into the shot cup "a preset cup for alcohol measurement " he takes stawberry puraee (strawberry mix) and pyrs it into the drink and mixes it around by shaking it . puts a extractor on top of it and takes a glass and pours the drink in front of you into the glass. you dont see the vodka in there do you ? no you dont because its mixed in there same thing with lemonade.
Answer:
Four moles of electrons
Explanation:
The reactions in a breathalyzer are redox reactions. Fuel cell breathalyzers consists of fuel cells with platinum electrodes. The current produced depends on the amount of alcohol in the breath. Detection of alcohol involves the oxidation of ethanol to ethanoic acid. The two half cells set in the process are;
Anode;
C2H5OH(aq) + 4OH^-(aq) ----------> CH3COOOH(aq) + 3H2O(l) + 4e
Cathode;
O2(g) + 2H2O(l) +4e--------> 4OH^-(aq)
Hence four electrons are transferred in the process.
Answer:
Molar masses of X and Z
Explanation:
To determine the mole percent of a mixture ( mole percent of unknown metals = number of mole of each of them divided the total of both the unknown salt × 100) since the percent by mass is know; we the molar mass of X and Z
mole = mass given / molar mass
<u>Epipelagic </u>zones are warm, well lit, and have lots of marine life.
Explanation:
This is the topmost zone of the oceans extending about 200 meters from the ocean surface. This zone is well lit because sunlight is able to penetrate this layer before it discusses as it penetrates deeper into the ocean. Therefore, this epipelagic zone is able to sustain plankton (that are photosynthetic). Plankton form the base of marine life which is why they support a large marine ecosystem in the epipelagic zone and thie energy flow even to the deeper abyssopelagic zone.
12.5%
Three half lives pass. 50% -> 25% -> 12.5%
