Will made a cup of hot tea and placed it on the tableA few minutes later, he picked up the cup and touched the warm table where

the cup had been sitting put the cup back in the same place and left the kitchenWhen he returned a few hours later , he noticed the table and the cup felt the same temperature as other Which of these statements best describes the heat flow between the cup and the table?
A The heat flowed from the table to the cup through the process of convection
B The heat flowed from the table to the cup through the process of conduction
C.The heat flowed from the cup to the table through the process of conduction.

Convert 7.50 mol of Li₂O to grams
Natali5045456 [20]

Answer:

223.5 g

Explanation:

The formula between the number of moles, mass and Mr can be used to convert moles to grams.

<em>Number of moles = mass ÷ Mr</em>

So, mass = number of moles × Mr

  Mr of Li₂O = (6.9 × 2) + 16 = 29.8

∴ Mass = 7.5 × 29.8 = <u>223.5 g</u>

Predict the number of peaks that you would expect in the proton-decoupled 13C spectrum of each comound.
dangina [55]

Answer:

To interpret a 13C-NMR spectrum we will use some standards very simple. A  13C-NMR spectrum gives us the following information:

1. Indicates the number of non-equivalent carbons in the molecule.

2. Measuring the chemical shift we can intuit the environment

electronic and determine the next functional groups.

3. In this case we cannot count on integration since the different

carbons have different relaxation times.

The number of peaks in the spectrum indicates the number of types of carbon present in the analyzed substance.

The factors that influence the chemical shift of the signals in the 13C NMR are:

  • electronegativity of carbon bound groups
  • carbon hybridization

Explanation:

The nuclear magnetic resonance of C13 is complementary to that of H1. This technique is used to determine the magnetic environment of carbon atoms.

Amanda paired with Janice while Deja paired with Eden for a chemistry project. For the Earth science project, Amanda paired with
pashok25 [27]

The chemical reaction that the situation demonstrates would be a double replacement reaction.

In double replacement reactions, the two reactants participating in the reaction are similarly built in terms of their chemical bonds and they exchange ions to form the products of the reaction. Two products are also formed from the two reactants.

It is as opposed to single replacement reactions in which the two reactants are not similar bond-wise. One of the reactants replaces or displaces one of the ions in another reactant.

In this case, the situation can be represented as follows:

Amanda-Janice + Deja-Eden ----> Amanda-Eden + Deja-Janice

Thus, it is a form of double replacement reaction.
