Select the correct layer.
In which layer is lithification most likely to occur?

Answer:

Specific heat of solid A is greater than specific heat of solid B.

Explanation:

In the calorimeter, as the temperature is increasing, the vibrational kinetic energy will increase and this means that additional amount of energy will be needed to increase the temperature by the same value. Therefore, we can conclude that specific heat increases as temperature increases.

Now, we are told that the final temperature of solid A's calorimeter is higher than that of B.

This means from our definition earlier, Solid A will have a higher specific heat that solid B.

here's the answer to your question

13.41 moles are present in 2.20 kg of sodium phosphate.

A mole is defined as 6.02214076 × [tex]10^{23}[/tex]of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

The molar mass of sodium phosphate is 163.94 g/mol.

2.20 kg = 2200g

[tex]Moles = \frac{2200g}{163.94 g/mol.}[/tex]

Moles = 13.41954374 = 13.41 moles

Hence, 13.41 moles are present in 2.20 kg of sodium phosphate.

Answer:

Arginine is intermediate product formed during the production of urea

The key combination is ornithine, on which the urea molecule is 'created'; intermediates in the procedure contain citrulline and arginine.

The urea cycle is a procedure of conversion of toxic ammonia to negligibly toxic urea. Consequences of the urea cycle are 1 molecule of urea, 2 molecules of ADP, and 1 molecule of both AMP and fumaric acid.

When Ammonia and carbon dioxide recovery During urea decomposition a mixture of gaseous carbon dioxide and also ammonia is accumulated and also immersed into a dilute aqueous urea resolution.

Answer:

in fractional distillation we look at different boiling point of the mixture

Explanation:

argon will be separated from the mixture first because it has the lowest boiling point

The mixture of elements of gases of neon,argon, krypton and xenon can be separated using  fractional distillation as the  have difference in their boiling points.

An element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.

Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.

The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

Answer:

See explanation

Explanation:

The balanced equation for the formation of sulphuric acid is;

2SO2 + O2 + 2H2O → 2H2SO4

If 1 mole of SO2 occupies 22.4 L

x moles occupy 67.2 L

x = 1 × 67.2/22.4

x= 3 moles

From the reaction equation;

2 moles of SO2 yields 2 moles of H2SO4

Hence 3 moles of SO2 also yields 3 moles of H2SO4

Theoretical yield of H2SO4 = 3 moles × 98 g/mol = 294 g

Percent yield = actual yield/theoretical yield × 100

Percent yield = 250g/294g × 100

Percent yield = 85%

Explanation:

Iron is a metal

Answer:

The limiting reactant is oxygen gas and the reaction would produce 3.932 x 10 ^ 7 moles of water

Explanation:

Step 1: Convert everything into moles

nH2(l) = 1.06 x 10^8 g / 2.016 g/mol = 5.26 x 10^7 mols

nO2(l) = 6.29 x 10^8 g / 32.00 g/ mol = 1.966 x 10^7 mols

Step 2: Find the limiting reagent

The limiting reagent would be oxygen gas from

the balanced equation because we have less moles of oxygen gas needed to fully combust with the hydrant gas

Step 3: Stoichiometry time

The mole ratio from oxygen gas to water is 1:2

This means that for every mole of oxygen gas two moles of water is produced

We need to multiply the moles of oxygen gas by two to find out how many moles of water has been produced

nH2O = nO2 x 2

nH2O = 1.966x10^7 x 2

nH2O = 3.932x10^7

Step 4: Therefore statement

Therefore the limiting reactant is oxygen gas and the reaction would produce 3.932 x 10 ^ 7 moles of water

Answer:

The correct answer is It is a ratio of the concentrations in a reaction.

Explanation:

⇒ It is a ratio of the concentrations in a reaction.

This sentence is true because the equilibrium constant is calculated from the product of the concentration of the reaction products divided into the product of the concentrations of the reactants, each concentration raised by the stoichiometric coefficient. For example, for the following reaction:

aA + bB → cC + dD

The equilibrium constant is expressed as:

[tex]K = \frac{[C]^{c}[D]^{d} }{[A]^{a} [B]^{b} }[/tex]

⇒ It remains the same at different temperatures.

The sentence is false because the equilibrium constant changes with the temperature. In general, an endothermic reaction is favored by the increment of temperature (the equilibrium shifts to the right side) and disfavored with the decrease in temperature (shifts to the left).

⇒ It is represented by the symbol H.

This sentence is false because the equilibrium constant is represented with the letter K.

⇒ Its value is always close to 1.

It is not true because the equilibrium constant can be a number below or above 1.

K < 1 ⇒ there is more concentration of reactants at equilibrium

K > 1 ⇒ there is more concentration of products at equilibrium

1) Hacer una pregunta con respecto al fenómeno observado: ¿Por qué se apagó la estufa mientras se cocinaba la sopa?

2) Investigar sobre el tema: Los alimentos necesitan una fuente constante de calor para cocinarse. La estufa es la fuente de calor utilizada para la cocción de alimentos, existen dos modelos de estufas: (i) combustión de gas natural, (ii) inducción eléctrica.

Las estufas por combustión de gas natural requieren de un suministro de gas y una unidad de ignición, generalmente mantienen la llama una vez garantizado el suministro de gas natural. Son los modelos más económicos y comunes, aunque son las de menor eficiencia energética.

Las estufas por inducción eléctrica utilizan la energía eléctrica como suministro, la cual es transformada en calor por medio de inductores. Son más costosas que las estufas por combustión de gas natural, pero tienen mayor eficiencia energética.

Se debe determinar que tipo de estufa posee la madre de María. No obstante, una posible causa sea la interrupción del suministro, otra por daños en algún componente (gas natural o electricidad).

3) Elaborar una hipótesis: La estufa se apagó por una interrupción  en el suministro o por daños en el sistema.
