False. Due to:
Entropy increases with molecular size (mass of compound)
HBr has greater molecular size (molar mass) than HCl
The value of standard entropy of HCl(g) is 187 joules/ kelvin
The value of standard entropy of HBr(g) is 199 joules / kelvin
Answer:
The structure of stearic acid (octadecanoic acid) is shown in the attachment below
Explanation:
Stearic acid is an example of a saturated fatty acid. The structure of stearic acid is shown in the attachment below.
There are 1.51x10^24 atomsU in 2.50 mol of Uranium.
This is because a mole consists of 6.02x10^24 atoms. SO with this info,
2.5 x 6.02 x 10 = 1.505 x 10^24
but because we must round, the answer is 1.51 x 10^24

XD silliness aside, I hope this helped!
The equation MgO + 2HCl → MgCl₂ + H₂O is a balanced equation.
- A balanced chemical equation contains equal number of atoms on both sides of the equation.
- The equation is MgO + 2HCl → MgCl₂ + H₂O which contains 1 atom of Mg, 2 atoms of chlorine, 2 atoms of chlorine, 1 atom of oxygen on both reactants and products sides.
- So the equation is balanced.
- An equation for a chemical reaction is said to be balanced if both the reactants and the products have the same number of atoms and total charge for each component of the reaction.
- In other words, both sides of the reaction have equal amounts of mass and charge.
- It follows law of conservation of mass.
- Mass is neither created nor destroyed rather it can be transferred from one form to another.
