Answer:

Graphitic carbon nitride (g-C3N4) is a rising two-dimensional material possessing intrinsic semiconducting property with unique geometric configuration featuring superimposed heterocyclic sp2 carbon and nitrogen network, nonplanar layer chain structure, and alternating buckling. The inherent porous structure of heptazine-based g-C3N4 features electron-rich sp2 nitrogen, which can be exploited as a stable transition metal coordination site. Multiple metal-functionalized g-C3N4 systems have been reported for versatile applications, but local coordination as well as its electronic structure variation upon incoming metal species is not well understood. Here we present detailed bond coordination of divalent iron (Fe2+) through micropore sites of graphitic carbon nitride and provide both experimental and computational evidence supporting the aforementioned proposition.

How does a rock’s mass change when it goes through the rock cycle?
JulijaS [17]

The rock cycle is the process of converting rock between igneous, sedimentary, and metamorphic forms. ... Molten rock inside the Earth undergoes a phase change as it cools to produce solid igneous rock. The chemical changes which form the rock depend on the type of minerals present and how fast the rock cools.

Temka [501]

Answer:

meteor

Explanation:

The most logical identification of a "shooting star" is a meteor. A meteor is basically any material from outerspace that falls to Earth. The main characteristic of a meteor is that from our point of view on the surface of the Earth it looks like a shooting star because we see a streak of light behind it. This light is simply dust and rock from the meteor burning up as it enters the Earth's atmosphere, leaving a "tail" of light behind it. Which to us looks like a shooting star.

tia_tia [17]

Answer:

B). An Experiment that tests the hypothesis.

Explanation:

The element that is missing from Yasir's scientific investigation is 'an experiment which tests a hypothesis.' His experiment does not provide a verifiable statement revealing his proposition or prediction regarding the possible outcome of the experiment which could be verified by using a research or investigation. He rather tests his proposition indirectly by asking 'which color they like better' and using it to make an educated guess. Thus, <u>option B</u> is the correct answer.

Q # 1 For chemical reaction ,please help
horrorfan [7]

Answer:- d)  42 kJ of heat is released and the reaction is exothermic.

Solution:- Heat of reaction is the summation of heats of products - reactants.

\Delta H_r_x_n=\sum [products-reactants]

From given information, the energy contained by products is 352 kJ and the energy contained by reactants is 394 kJ. Let's plug in the values in the formula:

\Delta H_r_x_n  = [352 kJ - 394 kJ]

\Delta H_r_x_n  = -42 kJ

Heat of reaction is -42 kJ. The negative sign indicates the heat is released means the reaction is exothermic.  

So, the correct option is the last one, 42 kJ of heat is released and the reaction is exothermic.
