The number 650,000 written in scientific notation would be? and explain your answer
a) 2mg + ticl₄ ⟶ 2mgcl₂ + ti
b) 1.02 kg
a) balanced equation
we know we will need a balanced equation with masses and molar masses, so let’s gather all the information in one place.
m_r: 24.30 47.87
2mg + ticl₄ ⟶ 2mgcl₂ + ti
b) mass of mg
(i) calculate the moles of ti
n = 1.00 kg ti × (1 kmol ti /47.87 kg ti)
= 0.020 89 kmol ti
(ii) calculate the moles of mg
the molar ratio is (2 kmol mg/1 kmol ti)
n = 0.020 89 kmol ti × (2 kmol mg/1 kmol ti)
= 0.041 78 kmol mg
(iii) calculate the mass of mg
m = 0.041 78 kmol mg × (24.30 kg mg/1 kmol mg)
= 1.02 kg mg
you need 1.02 kg mg to produce 1.00 kg ti.
gain a higher average kinetic energy. rearrange into a more chronological order state, closer together, and they move more slowly.
here we have to choose the property of the liquid, among the given, which the engineer should primary look to use as the fluid of the engine.
the engineer should primarily looked the liquid which have b. low specific heat capacity.
the specific heat capacity of a substance is equivalent to the heat needed to increase 1⁰ temperature of the unit mass of the substance. now if the specific heat capacity of the liquid is low then it will need very little amount of energy to transfer the heat.
a. the low thermal conductivity will cause more time to exchange the energy. which is not required for the engine.
c. there is no relation between the reactivity of the liquid with the use of the same in the engine.
d. the internal energy will also not affect the rate of the cooling or heating of the liquid.
e. the high density also cannot affect the low rate of exchange energy.
