Answer:
True
Explanation:
Reason being there are 3 systems even in the open system the heat and matter goes in and out , the closed system the heat goes in and out as well and in the isolated system it stays in
Answer:
the pressure will increase
Answer:
See explanation.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to realize that the NaCl solution must react with an aluminum-containing substance, say the hydroxide or any other salt, so that the following equation will take place:
In such a way, given the volume of the NaCl solution, it must be necessary to know its concentration, in order to get moles of this salt, further use the 3:1 mole ratio of NaCl to AlCl3 and the molar mass of the latter (133.34 g/mol) in order to solve an stoichiometric setup like the following:
Besides, you must make sure the volume is in liters.
Best regards!
In terms of the disappearance of the reactants, the rate equations are R= -kd[I-]/dt and -kd[OCl-]/dt.
<h3>What is an ionic reaction?</h3>
The term ionic reaction refers to the reaction that takes place between two ions. In this case, the ionic reaction is; I-(aq) + OCl-(aq) -------> Cl-(aq) + OI-(aq).
The rate equations in terms of the disappearance of the reactants is;
R= -kd[I-]/dt
And
R = -kd[OCl-]/dt

<h2><em>Answer:
</em></h2><h2><em>
</em></h2><h2><em>d = 0.3 g/cm³
</em></h2><h2><em>
</em></h2><h2><em>Explanation:
</em></h2><h2><em>
</em></h2><h2><em>Density:
</em></h2><h2><em>
</em></h2><h2><em>Density is equal to the mass of substance divided by its volume.
</em></h2><h2><em>
</em></h2><h2><em>Units:
</em></h2><h2><em>
</em></h2><h2><em>SI unit of density is Kg/m3.
</em></h2><h2><em>
</em></h2><h2><em>Other units are given below,
</em></h2><h2><em>
</em></h2><h2><em>g/cm3, g/mL , kg/L
</em></h2><h2><em>
</em></h2><h2><em>Formula:
</em></h2><h2><em>
</em></h2><h2><em>D=m/v
</em></h2><h2><em>
</em></h2><h2><em>D= density
</em></h2><h2><em>
</em></h2><h2><em>m=mass
</em></h2><h2><em>
</em></h2><h2><em>V=volume
</em></h2><h2><em>
</em></h2><h2><em>Symbol:
</em></h2><h2><em>
</em></h2><h2><em>The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
</em></h2><h2><em>
</em></h2><h2><em>Given data:
</em></h2><h2><em>
</em></h2><h2><em>Mass = 6 g
</em></h2><h2><em>
</em></h2><h2><em>Volume = 20 cm³
</em></h2><h2><em>
</em></h2><h2><em>Density = ?
</em></h2><h2><em>
</em></h2><h2><em>Solution:
</em></h2><h2><em>
</em></h2><h2><em>d = m/v
</em></h2><h2><em>
</em></h2><h2><em>d = 6g/20 cm³
</em></h2><h2><em>
</em></h2><h2><em>d = 0.3 g/cm³</em></h2>
