Answer:
if i remember correctly it's B
Explanation:
The melting point of potassium = 
Melting point of titanium = 
Titanium has a stronger metallic bonding compared to potassium. Titanium being a transition metal has greater number of valence electrons (4 valence electrons) contributing to the valence electron sea compared to potassium which has only one valence electron. The atomic size of Titanium much lower than that of potassium, so the bonding between Titanium atoms is stronger than that of potassium. Hence, the melting point of Titanium is much higher than that of potassium.
Answer:
Consuming electricity: Burning fossil fuels emits CO2, with coal releasing twice as much of the gas as petroleum. Worldwide, fossil fuels generate 85 percent of electricity. The number of coal-burning plants will increase as China and India continue to industrialize.
For this problem, you first find the net resistance of the circuit which can be done by adding up the resistors since this circuit is a series. 10Ω+5Ω+6Ω=21Ω
Since we are given the current of 6A, we can use Ohm’s Law of V=IR.
V=6A*21Ω
V=126 volts
Answer:
B. 2 nitrogen, 4 hydrogen, and 3 oxygen
