Hi.

What are the symbols of the two elements which are liquid.

Bromine and Mercury is your answer.

Bromine (symbol Br and atomic number 35) and mercury (symbol Hg and atomic number 80) are both liquids at room temperature. Bromine is a reddish-brown liquid, with a melting point of 265.9 K. Mercury is a toxic shiny silvery metal, with a melting point of 234.32

AGO H2SO4 (aq) Al(SO4)3(aq) H28) fe Cl218) FeCl38<br>​
Rina8888 [55]

Answer:

2Al + 3H2SO4 → Al2(SO4)3 + 3H2

2Fe + 3Cl2 → 2FeCl3

Explanation:

1. (SO4) 3 you see this 3 it means that 3 must be behind H2SO4. So now it's 3H2SO4.

2. If 3 is now behind one H2, it must be behind the other.

So now it's 3H2.

3. Al2 (SO4) 3 has 2 ahead of Al which means there will be 2Al in the reactants.

1. FeCl3 has 3 ahead of Cl, and Cl2 has 2. Which means that behind FeCl3 goes 2, and behind Cl2 goes 3 so now we have equated all Cl.

2. Since it is now 2FeCl3, we know that there must be 2 in the second Fe. It's 2Fe now.

Select any of the following combinations which would make a good buffer solution?
KengaRu [80]

Answer:

b. 0.05 M H₂CO₃ + 0.05 M KHCO₃

d. 0.1M HCN + 0.2M NaCN

g. 0.2M NH₃ + 0.1M NH₄Br

Explanation:

A buffer solution consists of the following components:

  • A weak acid and its conjugate base.
  • A weak base and its conjugate acid.

<em>Which would make a good buffer solution?</em>

<em>a. 0.3 M HC₂H₃0₂ + 0.1 M HCI</em>

It does not have the components of a buffer solution. HCl is a strong acid.

<em>b. 0.05 M H₂CO₃ + 0.05 M KHCO₃</em>

It is a good buffer because it has a weak acid (H₂CO₃) and its conjugate base (HCO₃⁻), which comes from the salt.

<em>c. 0.05 M KC₂H₃O₂</em>

It does not have the components of a buffer solution.

<em>d. 0.1M HCN + 0.2M NaCN</em>

It is a good buffer because it has a weak acid (HCN) and its conjugate base (CN⁻), which comes from the salt.

<em>e. 0.2M NaF + 0.2M NaOH</em>

It does not have the components of a buffer solution. NaOH is a strong base.

<em>f. 0.3M NH₄Cl</em>

It does not have the components of a buffer solution.

<em>g. 0.2M NH₃ + 0.1M NH₄Br</em>

It is a good buffer because it has a weak base (NH₃) and its conjugate acid (NH₄⁺), which comes from the salt.
