Is four electrons the answer you’re looking for?
Answer:
Explanation:
Hello,
In this case, as the atomic mass of coppe is 63.546 g/mol, with the given mass with can compute the moles as shown below:
Best regards.
Answer:
3.6 × 10²⁴ molecules
Explanation:
Step 1: Given data
Moles of methane (n): 6.0 moles
Step 2: Calculate the number of molecules of methane in 6.0 moles of methane
In order to convert moles to molecules, we need a conversion factor. In this case, we will use Avogadro's number: there are 6.02 × 10²³ molecules of methane in 1 mole of molecules of methane.
6.0 mol × 6.02 × 10²³ molecules/1 mol = 3.6 × 10²⁴ molecules
Answer: A
Explanation: the only way to turn it from blue to yellow is to mix it with an acidic solution.
Answer: C. Convection currents in the asthenosphere.
Explanation: Most geologists think that the movement of Earth's plates is caused by convection currents in the asthenosphere.
