11) How many significant figures would be in your correctly rounded

Chemistry
1 answer:
Lilit [14]3 years ago
8 0

Answer:

2

Explanation:

Unfortunately, despite the careful measurements of the last two numbers, the first only tells us a measurement in the tens is accurate.  The zero is a placeholder.  If the numbner were written 230.0, it would have 4 sig figs, but the number as written only has two sig figs.

Voltages listed in textbooks and handbooks are given as standard cell potentials (voltages). What is meant by a standard cell?
Allushta [10]

Answer:

Find the definition below.

Explanation:

A standard cell is a group of transistors that have a regular electromotive force flowing through them. They follow either the boolean function or the storage function. A technology library that is made up of a collection of standard cells can be used to facilitate the placement, routing, and synthesis of the Application-specific Integrated Circuit (ASIC).

Electronic Design Automation is an example of an apparatus that implements this functionality.

Write the equilibrium constant expression for the reaction below.
kodGreya [7K]

Answer:

Kc = [H₂S]² . [CH₄] / [ H₂O]⁴ . [CS₂]

Explanation:

The equilibrium constant indicates the % of the yield reaction and can shows where the reaction is going to be equilibrated.

It works with molar concentrations on the equilibrium and it does not consider the solids compounds

Kc also can be modified by the time of the reaction.

This reaction is:

CS₂ (g) + 4 H₂O(g) ⇌ CH₄ (g) + 2H₂S (g)

Kc = [H₂S]² . [CH₄] / [ H₂O]⁴ . [CS₂]
