Answer:
771.15g of TiCl4
Explanation:
460 grams of sodium=20 mol
equation of the reaction is TiCl4+4NA=4NaCl+Ti
1 mol of titanium chlroide reacts with 4. that means there are 5 mols of titanium chloride
titanium chloride has a molar mass of 154.23 g.
mutiply that by 5 and we have 771.15 g
The correct answer you're looking for is C. Sn and Ag. Hope this is the answer you were looking for and that it helps. :)
Direct current is electromotive force powering from a battery. Adding bulbs increases resistance.
Resistance equals volts divided by current.
Or current equals volts divided by resistance. Current lowers.
Answer is
C. 2.07 M
For explanation
M1V1 = M2V2
M2 = (M1V1)/V2
M2 = (1.5M x 345ml) / 250 ml
:. M2 = 2.07 M
Answer:
<u>Option B is correct</u>
Explanation:
Step 1: Define volatility
In chemistry, the term volatility, is a way to describe how readily a substance transitions from a liquid phase to a gas phase, also called evaporating.
At a given temperature and pressure, a substance with high volatility is more likely to evaporate more quickly , while a substance with a lower volatility is more likely to be a liquid or solid, so not to evaporate or slower.
The higher the volatility, the higher the (vapor) pressure of a compound. Increasing temperature means the vapor pressure will also increase,
Step 2: In this case:
⇒ O<u>ption A is false</u> because the pressure will be higher when volatility is higher.
<u>⇒ Option B is correct</u> because higher volatility means evaporating more quickly
<u>⇒ Option C is false</u> because higher volatility means higher pressure. When pressure increases, the surface tension decreases.
<u>⇒ Option D is false</u> because when the volatility is higher, the liquid/gas escape the container, easier, so there will be less resistance.
