Titanium is ductile and has high resistance for heat despite its strength.
Titanium (Ti), is a Group 4b chemical transition element, it has a silvery gray appearance. Its characteristics are as follows
- known as the strongest metal with high rigidity
- low-corrosion resistance
- low density
- heat resistance.
Because of these features, Titanium is widely used in building aircraft, missiles, and ships and also in the production of prosthetics.
Answer:
26.74g
Explanation:
The equation of the reaction is;
SIO₂ + 3C --> SiC +2CO
From the balanced equation, the relationship between SiC and C is;
3 mol of C produces 1 mol of SiC
Converting mol to mass using; Mass = moles * Molar mass
Mass of SiC = 1 mol * 40.11 g/mol = 40.11g
This means;
3 mol of C produces 40.11g of SiC
2 mol of C produces xg of SiC
3 = 40.11
2 = x
x = 2 * 40.11 / 3 = 26.74g
Answer:
Explanation:
Tenochtitlan was located on a swampy island in Lake Texcoco in what is today south central Mexico. The Aztecs were able to settle there because no one else wanted the land. At first, it wasn't a great place to start a city, but soon the Aztecs built up islands where they could grow crops. The water also worked as a natural defense against attacks from other cities.
