While boiling potatoes for dinner in salted water, the pot boils over and you notice that the flame on your gas burner turns to

wel

Answer:

This observation can be explained under the following reasons:

High sodium content
Lowered heat temperature
Organic burn

Explanation:

High sodium content from the potato fluid causes the flame to turn yellow, as indicative of the presence of sodium (flame test).

The colour change could also be attributed to the drastic lowering of the burner heat. Finally, pure organics like wood and fats burn red, a would be the case with fluids from the boiled potatoes.

I hope this explanation was helpful.

An HCl solution has a concentration of 0.09714 M. Then 10.00 mL of this solution was then diluted to 250.00 mL in a volumetric f

cestrela7 [59]

Answer:

A. Concentration of diluted acid = 0.00389 M

B. Concentration of OH- in AgOH solution = 0.00012 M

Explanation:

A. Using the dilution formula: C1V1 = C2V2

Where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume.

From the data provided, C1 = 0.09714 M, V1 = 10.0 mL, V2 = 250.0 mL and C2 = ?

Making C2 subject of the formula above; C2 = C1V1/V2

C2 = 0.09714 M × 10 / 250 = 0.00389 M

B. Equation of the neutralization reaction is given below:

HCl + AgOH ---> AgCl + H₂O

From the equation, 1 mole of acid neutralizes 1 mole of base

Using the titration formula; CaVa/CbVb = na/nb

Where Ca is the concentration of the acid HCl = 0.00389 M

Va is the volume of acid = 7.93 mL

Cb is the concentration of base, AgOH = ?

Vb is volume of base = 250.0 mL

na/nb = mole ratio of acid and base = 1

Making Cb subject of the formula in the equation above; Cb = CaVa/Vb

Cb = 0.00389 M × 7.93 / 250

Cb = 0.00012 M

I need help on this I don't know how to do it

Monica [59]

Well, you would need to know how to properly name these chemical compounds and elemental compounds, specifically ionic compounds.

1. H2 + I2 -> 2HI - Synthesis
2. 2Li + 2HCl -> 2LiCl + H2 - SR - Single replacement
3. Na2CO3 -> Na2O + CO2 - Decomposition
4. 2HgO -> 2Hg + O2 - Decomposition
5. Mg(OH)2 -> MgO + H2O - Decomposition
6. Cu + Cl2 -> CuCl2 - Synthesis
7. Ca(ClO3)2 -> CaCl2 + 3O2 - Decomposition.
8. 2Li + 2H2O -> 2LiOH + H2 - Single Replacement Reaction.

The majority of the elements essential to life are found in what part of the periodic table?

IRINA_888 [86]

The rows in the top third - This group consists of elements like Sodium, Magnesium, Potassium and Calcium on the right and Chlorine, Carbon, Nitrogen and Oxygen on the left.
Sodium and Chlorine are components of salt, a very important compound of our blood, essential for transferring electrical signals from the brain to the rest of the body and vice versa. Calcium is the building block of our bones, while Magnesium and potassium ensure proper functioning of our organs.
