Answer:
Use E = h*c / lambda, where h is Planck's constant, c is the speed of light, and lambda is the wavelength.
E = (6.626 * 10^-34 J*s x 3.00 * 10^8 m/s) / (1*10^-6 m) = 1.99 * 10^-19 J
Explanation:
Answer:
On average, agriculture accounts for 70 percent of global freshwater withdrawals. In the last 30 years, food production has increased by more than 100 percent. FAO estimates that about 60 percent more food will be needed by 2050 to meet the food requirements of a growing global population.
Explanation:
Because i learnt this before and i aced a test about it dont worry
Am - it has an atomic number of 95 which is greater than 92.
Transuranium elements are elements with atomic levels greater than 92
Answer: M = 0.01 M C12H22O16
Explanation: First convert the mass of C12H22O16 into moles using the molar mass of the compound.
5 g C12H22O16 x 1 mole C12H22O16 / 342 g C12H22O16
= 0.01 mole C12H22O16
To calculate the molarity we will use the following formula.
M = n / L
= 0.01 mole / 1 L
= 0.01 M C12H22O16
P=nRT/V
P ≈ 1/V = decreasing volume
P ≈ T = increasing temperature
P ≈ n = adding one more mole of helium
