Answer:
The answer to your question is pH = 6.3
Explanation:
Data
pH = ?
[H⁺] = 4.73 x 10⁻⁷ M
pH is the measure of the concentration of [H⁺]. pH measures the acidity of the solution. If the value of pH is between 0 and 6.9, the solution is an acid. If the pH is 7.0 the solution is neutral and if the pH is between 7.1 and 14, the solution is an alkali.
Formula
pH = -log[H⁺]
Substitution
pH = -log[4.73 x 10⁻⁷]
-Simplification
pH = - (-6.3)
-Result
pH = 6.3
Answer:
B and C Reduce Emissions and Least fuel economy
Explanation:
Plug-in electric vehicles are related, fun and practical (also called electric cars or hybrid electric vehicles). We will reduce emissions and save you even money. EVs deliver more than individual advantages. EVs will allow the US to have a more diverse range of transportation fuel options. Last year the US used almost nine billion barrels of oil, of which two-thirds went into shipping. We are vulnerable to price increases and supply disruptions because of our dependence upon oil. EVs help reduce this threat, as almost all US electricity, including coal, nuclear, natural gas and renewables, is generated from domestic sources.Vehicles can also minimize the CO2 emissions, improve health, and reduce environmental damage that contribute to climate change and smog. Charging your EV for renewable, such as solar or wind, will further reduce these emissions. Link to a calculator on the right to the pollution disparity between the traditional and an EV. Discover how EV reduce pollution and their emissions during their life cycle.
What’s the question Bc I don’t understand what u are trying to ask
Answer:
Si.
Explicación:
Sí, podemos predecir si una solución acuosa será un buen conductor de corriente eléctrica si conocemos el soluto que se disuelve en ese líquido y su concentración o cantidad. Hay algunas sustancias que se ionizan cuando se agregan en un líquido como el agua. Debido a esta ionización, será un buen conductor de electricidad. Por ejemplo, la adición de una gran cantidad de cloruro de sodio en agua ioniza y hace que el agua sea un buen medio conductor de electricidad.
