1. Al(C₂H₅)₂OCl₃

Al(C₂H₅)₂OCl₃ is made from 5 different elements. They are Al, C, H, O and Cl. Number of atoms in each element can be found as follows.

number of Al atoms = 1
number of C atoms = 2 x 2 = 4
number of H atoms = 5 x 2 = 10
number of O atoms = 1
number of Cl atoms = 3
<span>
Total number of atoms = 1 + 4 + 10 + 1 + 3 = 19

2. </span>BCl₃<span> 

BCl</span>₃ is a simple neutral molecule. It consists of 2 different elements as B and Cl. Total number of atoms is 4. Number of atoms can be calculated as follows.

number of B atoms = 1
number of Cl atoms = 3

Total number of atoms = 1 + 3 = 4<span>

3. </span>H₂O + H⁺

H₂O makes H₃O⁺ (hydronium ion) with H⁺ which is a positive ion. H₃O⁺ consists of two different elements as H and O. Number of atoms are as follows.

number of H atoms = 3
number of O atoms = 1

Total number of atoms = 3 + 1 = 4

What type of solution forms when lithium chloride dissolved in water?
murzikaleks [220]
Answer: strong electrolyte.

Justification:

1) Lithium chloride is an ionic compound, highly soluble in water.

2)  This is the chemical equation:

LiCl(aq) → Li⁺ (aq) + Cl⁻ (aq)


3) Due to its ionic character and the small size of the ion Li⁺, LiCl dissociates almost completely, meaning the the solution is a strong electrolyte.

4) Electrolytes are solutions that carry electricity (the iones, charged species, are the carrierr of the electricity)

How many moles of hydrogen atoms are there in 1.25 x 1025 molecules of ethane? (C2H6)
krek1111 [17]

Answer:

124.56 moles of Hydrogen atoms.

Explanation:

We'll begin by calculating the number of moles of ethane that contains 1.25×10²⁵ molecules. This can be obtained as follow:

From Avogadro's hypothesis, 1 mole of any substance contains 6.02x10²³ molecules. This implies that 1 mole of ethane also contains 6.02x10²³ molecules.

Thus, 6.02x10²³ molecules are present in 1 mole of ethane.

Therefore, 1.25×10²⁵ molecules are present in = 1.25×10²⁵/6.02x10²³ = 20.76

Therefore, 20.76 moles of ethane contains 1.25×10²⁵ molecules.

Finally, we shall determine the number of mole of Hydrogen in 20.76 moles of ethane. This can be obtained as follow:

Ethane has formula as C2H6.

From the formula, 1 mole of ethane, C2H6 contains 6 moles of Hydrogen atoms.

Therefore, 20.76 moles of ethane will contain = 20.76 × 6 = 124.56 moles of Hydrogen atoms.

Therefore, 1.25×10²⁵ molecules of ethane contains 124.56 moles of Hydrogen atoms.

For the reaction: 4PH3(g) → P4(g) + 6H2(g) about 0.065 mol/s of PH3 is consumed in a 5.0 L flask. What are the rates of producti
hoa [83]

Answer: The rates of production of P_4 is 3.25\times 10^{-3} mol/Ls and H_2 is 0.0195 mol/Ls.

Explanation:

4PH_3(g)\rightarrow P_4(g)+6H_2(g)

Rate with respect to reactants is shown by negative sign as the reactants are decreasing with time and Rate with respect to products is shown by positive sign as the products are increasing with time.

Rate of the reaction=-\frac{1}{4}\frac{[d[PH_3]}{dt}=\frac{[d[P_4]}{dt}=\frac{1}{6}\frac{[d[H_2]}{dt}

Rate of decomposition of PH_3=\frac{0.065 mol/s}{5.0L}=0.013mol/Ls

Rate of production of P_4=\frac{1}{4}\times {\text{rate of decomposition of}} PH_3=\frac{1}{4}\times 0.013=3.25\times 10^{-3}mol/Ls

Rate of production of  H_2=\frac{6}{4}\times {\text {rate of decomposition of}} PH_3=\frac{6}{4}\times 0.013=0.0195mol/Ls
