The volume of the given solution is 2.5 L.
<u>Explanation:</u>
Volume of the solution = 2500 mL
We have to convert it into litres as,
1000 mL = 1 litre
To convert ml into litres we have to divide the millilitres by 1000, so that it can be converted into L.
Here given volume is 2500 mL.
Volume in L = 
= 2.5 L
So the volume of the solution is 2.5 L.
In an exothermic reaction, heat is released. ΔH for an exothermic reaction is negative. That means that the energy stored in the reactants is higher than the energy stored in the products.
The opposite is true for an endothermic reaction. Heat is absorbed, and <span>ΔH for an endothermic reaction is positive. This means that energy stored in the products is higher than the energy stored in the reactants.</span>
False. A buffering solution consists of a WEAK acid such as CH3COOH, C5H5N, or ammonia. <span>A buffering solution resists pH change upon the addition of an acidic or basic components. It can neutralize little amounts of added acid or base, thus maintaining the pH of the solution relatively stable. The correct answer is letter "B. false"</span>
Answer:
62.586 gram
Explanation:
moles of Al(OH)3 = mass / molar mass = 35.1 / (27+17x3) = 0.45 mol
moles of H2SO4 = mass / molar mass = 53.94 / (2+32+16x4) = 0.55 mol
H2SO4 is the limiting reagent (reacts completely)
⇒ moles of Al2(SO4)3 is worked out by moles of H2SO4
moles of Al2(SO4)3 = moles of H2SO4 / 3 = 0.183 mol
mass of Al2(SO4)3 = mole x molar mass = 0.183 x (27x2 + 96x3) = 62.586 gram
Answer:
The mass of the atom will change
Explanation:
The mass of the atom will alter if the changing the amount of electrons in an atom charge would result in being positively or negatively charged (Correct me if I'm incorrect sorry If I got this wrong)
