Flubber in this case would be a.... solid, though it might seem he could be a liquid/gas.... Hope it helps ~>~

What is wrong with this chemical equation - N2 + O2 → 2N20,

LUCKY_DIMON [66]

Answer and Explanation:

I think the thing that is wrong with this chemical equation is that there is 0 by the 2 instead of the letter O.

Other than that, everything would be balanced.

Determine the empirical formula of a compound containing 1.71 g of silicon and 8.63 g of chlorine.

Basile [38]

Answer:

The answer to your question is: SiCl₄

Explanation:

Data

amount of Si 1.71 g

amount of Cl 8.63 g

MW Si = 28 g

MW Cl = 35.5

Process (rule of three)

For Si For Cl

28 g of Si ------------------ 1 mol 35.5 g of Cl --------------- 1 mol

1.71g of Si --------------- x 8.63 g of Cl -------------- x

x = 1.71 x 1 / 28 = 0.06 mol x = 8.63 x 1 / 35.5 = 0.24 mol

Now, divide both results by the lowest of them.

Si = 0.06 mol / 0.06 = 1 molecule of Si Cl = 0.24 / 0.06 = 4 molecules of Cl

Finally

Si₁ Cl₄ or SiCl₄

A chemistry graduate student is given 500. mL of a 0.20 M chloroacetic acid (HCH2ClCO2) solution. Chloroacetic acid is a weak ac

zhenek [66]

Answer:

12 g of choloracetic acid

Explanation:

The buffer equilibrium is:

HCH₂ClCO₂ ⇄ CH₂ClCO₂⁻ + H⁺

pka= -log ka =

Ka: 1,3x10⁻³ = [CH₂ClCO₂⁻] [H⁺] / [HCH₂ClCO₂]

By Henderson-Hasselbalch equation:

pH = pka + log₁₀ [A⁻] / [HA]

3,01 = 2,89 + log₁₀ [A⁻] / [HA]

1,318 = [A⁻] / [HA]

As molar concentration of chloroacetic acid (HA) is 0,20M

[A⁻] = 0,26 mol/L

The volume is 500 mL ≡ 0,5 L

0,26mol/L × 0,5 L = 0,13 moles of chloroacetic acid. In grams:

0,13 mol × (94,5g / 1mol) = 12 g of choloracetic acid

I hope it helps!

Same group element have same Valence electron and behave similarly in Chemistry.

Explanation:

For example. First group elements Alkali metals:- H, Li, K, Rb, Cs, Fr

Valance electron will take part in forming a bond with other elements and compound will form. All the above-given elements (H-Fr) have valence electron 1 in outer most 'S' shell. All have electronic configuration S1

Behavior: Since valence electrons are the same so the behavior of all the elements in this group is the same. All are metal (from Li-Fr, except Hydrogen), all are very reactive, does not found in native state in the environment, and all react with water.
