We know that acids have a pH of under 7.
We also need to:
Set up an ICE table for the chemical reaction. Solve for the concentration of H3O+ using the equation for pH Use the concentration of H3O+ to solve for the concentrations of the other products and reactants.
Answer:
2
Explanation:
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
Answer:
1. The body's immense blood supply (when blood vessels dilate or become larger heat loss occurs) When the blood vessels constrict it holds in heat
2. The skins blood supply also helps maintain body temperature (helps maintain homeostasis which is the "normal" state of our body)
3. Humidity in the air effects thermoregulation (heat regulation in the body) by limiting sweat evaporation (usually sweat evaporates into the environment when the humidity is low because the air has low "water levels" per say while you have high "water levels" because of your sweat
Answer:
36 gallons of each first brand and 24 gallons second brand of antifreeze must be used.
Explanation:
Let the volume of two different antifreeze be x and y.
Total volume required = 60 gal
x + y = 60 gal ...(1)
In order to obtain 60 gallons of a mixture that contains 45% pure antifreeze.



On solving equation (1) ans (2), we get:
x = 36 gal, y = 24 gal
36 gallons of each first brand and 24 gallons second brand of antifreeze must be used.
