Answer:

I think the layers of the atmosphere does temperature increase with increasing height. It is affected by convection because it heats the lower atmosphere. It is affected by conduction because the is the transfer of thermal energy. I guess

Hope this help!

aniked [119]

Answer:

Exotérmica.

Explanation:

¡Hola!

En este caso, dado que la mayoría de reacciones de combustión son exotérmicas, al generar calor en los productos, es posible inferir que esta reacción, referida a la combustion de metano es exotérmica debido a lo anteriormente mencionado, ya que el término de energía de reacción, 531 kcal, está al lado de los productos, lo que quiere decir que es energía generada.

¡Saludos!

What is the ph of 0.51 m ca(ch3coo)2 solution?

Sidana [21]

Answer : The pH of calcium acetate solution will be 9.38.

Explanation : When calcium acetate dissocates completely in solution to form Calcium(+2) ions and two acetate ions, this gives the acetate ion concentration as (2 X 0.51 M) = 1.02 M

Acetate ion then hydrolyzes as follows;

$C_{2}H_{3}O_{2}^{-} + HOH HC_{2}H_{2}O_{2} + OH^{-}$ :

Now, Kb will be = $[HC_{2}H_{2}O_{2}] [OH^{-}]$ / $[C_{2}H_{3}O_{2}^{-}]$

= Kw / Ka

= 1 x $10^{-14}$ / 1.8 x $10^{-5}$ = 5.6 × $10^{-10}$

$[OH^{-}]$ = 2.4 × $10^{-5}$

Now, we know , pOH = -log $[OH^{-}]$ = 4.62

So, the pH = 14 - pOH = 14 - 4.62 = 9.38

What mass of ch4 is consumed when 587. 9 kj of energy is evolved from the combustion of a mixture of ch4(g) and o2(g)? show the

katen-ka-za [31]

Mass of CH₄ is 10.591 g.

The molar mass is a crucial characteristic of the material that is independent of sample size. The coherent unit of molar mass in the International System of Units (SI) is kg/mol. However, molar masses are usually generally given in g/mol due to historical considerations.

A chemical compound's molar mass is calculated by dividing its mass by the number of moles of the substance that make up the sample.

Δg = 587.9 KJ

CH₄ Molar mass = 16.05 g/mol

mol CH₄ = Δg / ΔH°

= 587.9 / 890.3 KJ/ mol

= 0.6603 mol CH₄

Mass CH₄ = 0.6603 × 16.05 g/mol

= 10.591 g

Therefore, the mass of CH₄ is 10.591 g.
