2HF + Na2SiO3 ----> 2NaF + H2SiO3 is the balanced equation.
2 moles of HF form 2 moles of NaF
therefore 0.508 Mol HF forms 0.508 mol of NaF
In grams this is 0.508( rel atomic mass of Na + RAM of F)
= 0.508 (22.99+19)
= 21.33 grams

Answer:
glycerol-3-phosphate, ADP, H⁺
Explanation:
The reaction of converting glycerol to glycerol-3-phosphate which makes is unfavorable and is coupled with the second reaction which involves conversion of ATP to ADP which is high energetically favorable.
Reaction 1: Glycerol + HPO₄²⁻ ⇒ Glycerol-3-phosphate + water
Reaction 2: ATP + H₂O ⇒ ADP + HPO₄²⁻ + H⁺
The coupled reaction of both the reactions become favorable. Thus, the overall coupled reaction is:
<u>Glycerol + ATP ⇒ Glycerol-3-phosphate + ADP + H⁺</u>
The net products are = glycerol-3-phosphate, ADP, H⁺
Answer:
9000J
Explanation:
Given parameters:
Mass of the jet fighter = 5kg
Velocity = 60m/s
Unknown:
Kinetic energy of the jet fighter = ?
Solution:
The kinetic energy of a body is the energy due to motion of the body.
It is mathematically expressed as;
K.E = 
m v²
m is the mass
v is the velocity
So;
K.E = x 5 x 60² = 9000J
