Answer:

The correct answer is c. the acetate ion acts as a Bronsted-Lowry base in a reaction with water.

Explanation:

Sodium acetate (NaCH₃COO) dissociates in water to give Na⁺ and CH₃COO⁻ ions as follows:

NaCH₃COO(s) → Na⁺(aq) + CH₃COO⁻(aq)

The acetate ion (CH₃COO⁻) is the conjugated base of acetic acid (CH₃COOH). Acetic acid is a weak acid, so the acetate ion will try to regenerate the weak acid. For this, it will acept a proton (acting as a Bronsted-Lowry base) from water to form acetic acid. As result, OH⁻ is released and the solution turns basic:

CH₃COO⁻(aq) + H₂O(l) ⇄ CH₃COOH(aq) + OH⁻(aq)

If the volume of a substance is measured with a graduated cylinder, the unit of measure for volume will be:
nirvana33 [79]

Answer:Today they will practice measuring different liquids. They will use a container called a graduated cylinder to measure liquids. Graduated cylinders have numbers on the side that help you determine the volume. Volume is measured in units called liters or fractions of liters called milliliters (ml).

In a coffee-cup calorimeter, 100.0 g of H2O and 100.0 mL of 1M HCl are mixed. The HCl had an initial temperature of 44.6 C and t
Hatshy [7]

Answer:

Exothermic reaction for the HCl, endothermic reaction for the water

2803.28\ \text{J}

Explanation:

Heat was lost by HCl as its temperature lowered, so it was an exothermic reaction for the HCL.

Heat was gained by water as its temperature increased, so it was an endothermic reaction for the water.

m = Mass of water = 100 g

c = Specific heat of water = 4184\ \text{J/kg}^{\circ}\text{C}

\Delta T = Change in temperature of water = (31.3-24.6)^{\circ}\text{C}

Heat is given by

Q=mc\Delta T\\ =0.1\times 4184\times (31.3-24.6)\\ =2803.28\ \text{J}

Heat gained by water is 2803.28\ \text{J}.

Which equation represents a redox reaction?
labwork [276]

Answer:

D. 2NaBr + Cl_2\rightarrow 2NaCl + Br_2

Explanation:

Hello!

In this case, for the given set of chemical reactions, it is possible to infer that D. is a categorized as redox due to the following:

Since both chlorine and bromine remain as diatomic gases, their oxidation states in such a form is 0, but as anions with lithium cations they have a charge of - according to the following reaction and half-reactions:

2NaBr + Cl_2\rightarrow 2NaCl + Br_2

Cl_2^0+2e^-\rightarrow 2Cl ^-\\\\2Br^- \rightarrow  Br_2^0+2e^-

Unlike the other reactions whereas no change in the oxidation states is evidenced.

Which element has this electron configuration? <br> astatine<br> bromine<br> chlorine<br> fluorine
oksano4ka [1.4K]
Unfortunately you did not specify the electronic configuration in the question, however since one of the answers must be a halogen, i took the liberty to attach an image with the configuration (both the simple numeric and spdf form) for all the halogen and all you have to do is match the electronic configuration you have in your question to the one in the table attached and you can then deduce the answer.

Hope this helps.
