False. The center of the earth is hotter than the surface of the sun.The surface of the Sun is hot - over 5500 degrees Celsius (which is nearly 10,000 degrees Fahrenheit . But if new findings are correct, then the center of our own planet may actually be hotter - over 1,000 degrees hotter than previously thought.

Respuesta:

d. Ninguno tiene la razón

Explicación:

Para convertir masa a moles, necesitamos la masa molar de cada sustancia.

Fernando (58.85 g Fe)

La masa molar de Fe es 55.85 g/mol.

58.85 g × 1 mol/55.85 g = 1.054 mol

Jacqueline (23.05 g Na)

La masa molar de Na es 22.99 g/mol.

23.05 g × 1 mol/22.99 g = 1.003 mol

Carlos (35.45 g Cl)

La masa molar de Cl es 35.45 g/mol.

35.45 g × 1 mol/35.45 g = 1.000 mol

Paola (27.0 g Al)

La masa molar de Al es 26.98 g/mol.

27.0 g × 1 mol/26.98 g = 1.00 mol

<h3>What is factor analysis?</h3>
  • Factor analysis is a statistical approach for describing variability in seen, correlated variables in terms of a possibly smaller number of unobserved variables known as factors.
  • It is possible, for example, that fluctuations in six known variables mostly reflect variations in two unseen (underlying) variables.
  • Factor analysis looks for such joint fluctuations in response to latent variables that are not noticed.
  • Factor analysis may be regarded of as a specific form of errors-in-variables models since the observed variables are described as linear combinations of the possible factors plus "error" terms.
  • It may help to deal with data sets where there are large numbers of observed variables that are thought to reflect a smaller number of underlying/latent variables.
  • It is one of the most commonly used inter-dependency techniques and is used when the relevant set of variables shows a systematic inter-dependence and the objective is to find out the latent factors that create a commonality.
