What would probably happen if it took the Earth longer to orbit the Sun than it does now? * A. A year would have fewer than 365 days.
B. A year would have more than 365 days.
C. Animals could jump higher than they normally can now.
D. People would weigh twice as much as they normally do now.

B

the Earth is eccentric,this means that it has changed repeatedly over time

And if it took the earth more time to orbit round the sun than it does now the years would have more than Han 365 days a year

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
