B. Electrical, chemical, thermal, mechanical.
Turning the ignition switch on sends an electrical signal, which starts the chemical combustion of the fuel. This gets the engine going, which produces heat (thermal).
Answer:
V₂ = 956.52 L
Explanation:
Given data:
Initial pressure = 4 atm
Initial volume = 550 L
Final volume = ?
Final pressure = 2.3 atm
Solution:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
4 atm × 550 L = 2.3 atm × V₂
V₂ = 2200 atm. L/ 2.3 atm
V₂ = 956.52 L
Answer:
The molecular formula of mono sodium glutamate is
Explanation:
Molar mass of sodium glutamate,M = 169 g/mol
let the molecular formula be
Percentage of carbon in the M.S.G. =35.52 %
a = 5
Percentage of Hydrogen in the M.S.G. = 4.77 %
b = 8
Percentage of oxygen in the M.S.G. =37.85 %
c = 3.99 ≈ 4
Percentage of nitrogen in the M.S.G. = 8.29 %
d = 1
Percentage of sodium in the M.S.G. =13.60 %
e = 0.99 ≈ 1
The molecular formula be :
Since X is 1 g, therefore O must be 0.1 g. Therefore:
moles O = 0.1 g / (16 g / mol) = 0.00625 mol
We can see that for every 3 moles of O, there are 2 moles
of X, therefore:
moles X = 0.00625 mol O (3 moles X / 2 moles O) =
0.009375 mol
Molar mass X = 1 g / 0.009375 mol
<span>Molar mass X = 106.67 g/mol</span>
The word problem format to the task given above is: When magnesium reacts with steam, it produces magnesium hydroxide and liberate hydrogen gas.
<h3>How magnesium hydroxide is formed?</h3>
It happens that magnesium is an alkali earth metal and react with water in the gaseous state to librate hydrogen gas, when this reaction occurs, it results in the formation of magnesium hydroxide.
The chemical equation between magnesium and water is given below:
Mg + 2H₂O -----> Mg (OH)₂ + H₂
So therefore, we can accurately deduced that magnesium hydroxide is produced when magnesium is disolved in water.
