Answer:
Radioactive dating
Explanation:
Radioactive dating measures the ratio of C¹²(normal) and C¹⁴ (radioactive) in fossils to determine the exact age of the specimen. C¹⁴ is unstable and has a half life of 5730 years, so as the organism ages the amount of C¹⁴ diminishes but the amount of C¹² remains constant. The ratio of C¹⁴ to C¹² is used to analyze the decay of atomic particles to determine exact age.

After the addition of 6.47 mL of 0.303 M HCl. Solution :- lets first calculate the moles of the NaOCl and HCl Moles = molarity *volume in liter Moles of NaOCl = 0.100 mol per L * 0.053 L =0.0053 mol Moles of HCl =0.303 mol per L *0.00647L=0.00196
Answer:
Answer is option (d) (lowest to highest)
We have to rank the six vehicles according to the CO2 emission causing an impact on global warming. We know that burning of coal has the highest emission of all fossil fuel so EV powered by electricity from it will be the highest impact on global warming with highest CO2 emission, next is burning of gasoline, but the CO2 emission can be varied by the process of the burning in engines obviously a high-efficiency burning will have less impact than a regular standard engine. So, after ICEV standard will have high CO2 emission than the ICEV (high efficiency), now the next will be EV which is having its electricity supplied by a mix of resources, the production involves both fossil and non-fossil fuel which make this vehicle more environmentally friendly than the full fossil fuel-based. The ICEV with less driving has the second least emission because you are not burning the fuel like other vehicles because of not driving the vehicle. In the last will be the EV having powered by electricity of wind it will be the least emission almost zero because it using wind power to generate electricity. Hence arrangement comes like this, EV(wind), ICEV(less driving), EV (mix of sources), ICEV (high-efficiency), standard ICEV, EV (coal) from lowest to highest CO2 emission.
