Answer:
a) 2Mg + TiCl₄ ⟶ 2MgCl₂ + Ti
b) 1.02 kg
Step-by-step explanation:
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
m/kg: 1.00
b) Mass of Mg
(i) Calculate the <em>moles of Ti
</em>
n = 1.00 kg Ti × (1 kmol Ti /47.87 kg Ti)
= 0.020 89 kmol Ti
(ii) Calculate the <em>moles of Mg
</em>
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 <em>mass of Mg
</em>
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.
Answer:
Through the process of condensation
Explanation:
Condensation is when gas converts to liquid. Carbon Dixide in the air will eventually convert to water and ruin the ocean water, thus affecting coral reefs. Please mark brainliest :)
Answer:
Concentration solution A was 0.5225 M
Explanation:
10.00 mL of solution A was diluted to 50.00 mL and yields 50.00 mL of solution B
According to laws of dilution-
where, and are concentration of solution A and B respectively
and are volumes of solution A and B respectively
Here = 0.1045 M, = 50.00 mL and = 10.00 mL
Hence,
So, concentration solution A was 0.5225 M
In the north Atlantic the movement of tectonic plates(if that is what you meant by plates) is around.4 inches per year which is almost 1 cm but in the pacific area the movement is almost 2 inches which is more that four cm every year although some people say that they (in general not specific to any place in particular) travel in the range of 5-10 centimeters every year.
Answer: The oxygen atom in a water molecule carries a negative electrical charge.
Explanation:
A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms.
Hydrogen bonding (H-bonding) is an intermolecular force having partial ionic-covalent character. H-bonding takes place between a hydrogen atom (attached with an electronegative atom e.g. O, N and F) and an electronegative atom (O,N and F).
In , , O is a highly electronegative atom attached to a H atom through a covalent bond. Therefore O atom gets partial negative charge and H atoms get partial positive charge.
