Chemistry
1 answer:
wlad13 [49]3 years ago
6 0

Answer:

The answers are (A.) Carboxylate ions have resonance, while alkoxides and acetylides don't (D.) Both carboxylic acids and carboxylates have resonance stabilization

Explanation:

When alcohols or alkynes donate a proton (H+), they become alkoxides acetylides respectively. Carboxylic acids on the other hand form carboxylate ions.

Carboxylate ions are more stable than their alkoxide and acetylides counterparts, because they possess a resonance structure which disperses its negative charge and allows for the valence electrons to be effectively delocalized.

Hence, carboxylic are more acidic than alcohols or alkynes.

which components of an endothermic reaction have a higher heat content?-reactants-products-reaction vessel-water
lana66690 [7]
Please, observe that it is not right to say that a substance content heat.

Heat is not something that a body or substance content. Heat is the transmission of energy due to difference of temperatures.

An endothermic reactions is that where the reactants abosorb energy from the surroundings to occur. The products, then, will be higher in energy than the reactants while the surroundings get colder.

Differentiate the claims made by science from those based on bias.
Readme [11.4K]

Answer:

Scientists seek to eliminate all forms of bias from their research. However, all scientists also make assumptions of a non-empirical nature about topics such as causality, determinism and reductionism when conducting research. Here, we argue that since these 'philosophical biases' cannot be avoided, they need to be debated critically by scientists and philosophers of science.

Explanation:

Scientists are keen to avoid bias of any kind because they threaten scientific ideals such as objectivity, transparency and rationality. The scientific community has made substantial efforts to detect, explicate and critically examine different types of biases (Sackett, 1979; Ioannidis, 2005; Ioannidis, 2018; Macleod et al., 2015). One example of this is the catalogue of all the biases that affect medical evidence compiled by the Centre for Evidence Based Medicine at Oxford University (catalogueofbias.org). Such awareness is commonly seen as a crucial step towards making science objective, transparent and free from bias.
