What volume in milliliters of 1.420 M sulfuric acid is needed to neutralize 3.209 g of aluminum hydroxide 3 H 2 SO 4 (aq)+2 Al(O
nadya68 [22]

Answer:

V=43.46mL

Explanation:

Hello!

In this case, since the reaction between sulfuric acid and aluminum hydroxide is:

3H_2SO_4+2Al(OH)_3\rightarrow Al_2(SO_4)_3+6H_2O

Whereas the ratio of sulfuric acid to aluminum hydroxide is 3:2; thus, we first compute the moles of sulfuric acid that complete react with 3.209 g of aluminum hydroxide:

n_{H_2SO_4}=3.209gAl(OH)_3*\frac{1molAl(OH)_3}{78.00gAl(OH)_3} *\frac{3molH_2SO_4}{2molAl(OH)_3} \\\\n_{H_2SO_4}=0.0617molH_2SO_4

Then, given the molarity, it is possible to obtain the milliliters as follows:

V=\frac{n}{M}=\frac{0.0617mol}{1.420mol/L}*\frac{1000mL}{1L}\\\\V=43.46mL

Best regards!

Predict the products of the following nuclear reactions...​
koban [17]
1. According to Rutherford and soddy's law of Beta emission:

{K}^{42} \: ---> {Ca}^{40} + {2e}^{0}

3. According to Rutherford and soddy's law of Alpha emission:

{U}^{238} \: ---> {Th}^{234} + {He}^{4}

4. The process in which two or more light nuclei are combined to form a single nucleus with the release of tremendous amount of energy is called a nuclear fusion. The inner core of Sun is at very high temperature and is suitable for fusion. In fact the source of energy of Sun and other stars is nuclear fusion reactions.

Which of the following is an accurate mathematical expression of Dalton's law? Assume the variable ‘P' stands for pressure.
GaryK [48]
Dalton's law of partial pressures states that the total pressure of a mixture of gases is the sum of the partial pressures of its components:
\text {P}_{\text{Total}} = \text P_{\text {gas 1}} + \text P_{\text {gas 2}} + \text P_{\text {gas 3}} ...P
​Total

What is the net ionic equation for the reaction that occurs when you mix aqueous solutions of NaHCO3 NaHCO3 and HC2H3O2HC2H3O2
Verizon [17]

Explanation:

The net ionic equation of a reaction is obtained from the complete ionic equation after removing the spectator ions.

The balanced chemical equation for the reaction of sodium bicarbonate with acetic acid is shown below:

NaHCO_3(aq)+CH_3COOH(aq)->CH_3COONa(aq)+H_2O(l)+CO_2(g)

The complete ionic equation is:

Na^+(aq)+HCO_3^-(aq)+CH_3COO^-(aq)+H^+(aq)->CH_3COO^-(aq)+Na^+(aq)+H_2O(l)+CO_2(g)

The net ionic equation is:

HCO_3^-(aq)+H^+(aq)->H_2O(l)+CO_2(g)

Answer:The net ionic equation is shown below:

HCO_3^-(aq)+H^+(aq)->H_2O(l)+CO_2(g)
