If the temperature is 80° outside does the air transfer more or less thermal energy to a thermometer then if it is 60°

Less, because thermal energy is heat so if it gets colder there is less thermal energy.

Which organisms in this food web are carnivores? Select the two correct
LUCKY_DIMON [66]

The two correct options are Poison dart frog and Boa constrictor. Both these organisms are pure carnivores which are also known as pure meat eaters in the food web. Carnivores are organisms in the food chain that only meat-eaters and never take any type of vegetation in their diet.

Explanation:

  • A Poison dart frog purely survives on meat (meat- eater).
  • Long sticky tongues are used to catch their prey such as ants, flies, insects.
  • Since they produce high toxin levels, it has very few predators in the wild.
  • Boa constrictor is also an organism that eats only meat.
  • While they are young they eat prey like rats, squirrels and mice.
  • The type of attack used by a boa constrictor is an ambush attack type. It attacks its preys using the surprise factor.

How to do q solution, qrxn, moles of Mg , and delta Hrxn?
Helga [31]

Answer:

<em> 14, 508J/K</em>

ΔHrxn =q/n

where q = heat absorbed and n = moles

Explanation:

<em>m = mass of substance (g) = 0.1184g</em>

1 mole of Mg - 24g

<em>n</em> moles - 0.1184g

<em>n = 0.0049 moles.</em>

Also, q = m × c × ΔT

<em> Heat Capacity, C of MgCl2 = 71.09 J/(mol K)</em>

<em>∴ specific heat c of MgCL2 = 71.09/0.0049 (from the formula c = C/n)</em>

<em>= 14, 508 J/K/kg</em>

ΔT=  (final - initial) temp = 38.3 - 27.2

= 11.1 °C.

mass of MgCl2 = 95.211 × 0.1184 = 11.27

⇒ q = 11.27g × 11.1 °C × <em>14, 508 j/K/kg </em>

<em>= 1,7117.7472 J °C-1 g-1</em>

<em />

<em>∴ ΔHrxn = q/n</em>

<em>=1,7117.7472  ÷ 0.1184 </em>

<em>= 14, 508J/K</em>
