Use this diagram to answer the following questions. 7 Model The reactants in the above reaction are hydrogen (H,) and nitrogen (N,). The product is ammonia (NH,). In the space below, write a balanced chemical equation that represents the reaction. De 8 Analyze This reaction releases energy as heat. Explain whether the reaction is exothermic or endothermic and whether it obeys the law of conservation of energy. of P-

In the illustration, N is color-coded as blue and H is color-coded as white. What kind of change is represented by this illustration? Is absorbed or released when this change occurs? energy

please help me answer this questions

10. Nitrogen, hydrogen, and ammonia (NH3) are all composed of molecules. What is it about a molecule of ammonia that makes it a compound, whereas hydrogen and nitrogen are elements? A) There are four atoms making up an ammonia molecule. B) The ammonia molecule contains atoms of two different types of elements. C) An ammonia molecule has more than one bond. D) An ammonia molecule has a larger mass than the sum of the masses of its constituent atoms.

4. When 10.0g of ice melts into water, how many grams of water are produced? CS Scanned with Camscanemany

just need to know how to do part A so i can do the rest!

Are the physical properties of a substance, such as color, sufficient to identify the substance? Why or why not?

Is this a chemical or physical change? List your reasons. Was the Law of Conservation of mass followed? Explain. Write the formulas for the reactant(s) of this reaction. Write the formulas for the product(s) for this reaction.  Write the balanced chemical equation for this reaction. Be sure to include: states, catalysts, and heat if applicable.  Thank you for helping me I'm really struggling in this class

pour it 2. Still sleepy from a late night studying, you take the milk out of the refrigerator and pour it on your lemon juice to milk to make paneer (fresh cheese). As a group, craft a chemical explanation for the fact of coagulated milk onto your cereal. The last time you saw milk coagulate like that was when you added breakfast cereal. Unfortunately, by the time you notice the funny smell you have already poured clumps lemon juice to milk to make paneer (fresh cheese). As a group, craft a chemical explanation foea added that spoiled milk coagulates.

A. Compare the lattice energy of LiF to the lattice energy of NaCl. Explain the difference in values based on your understanding of Coulomb’s Law. B. Compare the lattice energy of MgO to the lattice energy of NaCl. Explain the difference in values based on your understanding of Coulomb’s Law. C. What two properties of Coulomb’s Law are being compared in parts A and B? Which seems to be more significant in terms of predicting lattice energy values?

The Structure of lonic Compounds/ Exit Ticket

What type of process is involved in going from elements to compounds and vice versa? Elements can combine to form compounds through _____chemical physical processes.   Compounds can decompose into elements through______chemical physical processes.

Not chemical but forms! such as button, images What are some of the basic form elements you encounter every day? What form elements do you prefer working with?

There are four sketches below. The first sketch shows a sample of Substance X. The three sketches underneath it show three different changes to the sample. You must decide whether each of these changes is possible. If a change is possible, you must also decide whether it is a physical change or a chemical change. Each sketch is drawn as if the sample were under a microscope so powerful that individual atoms could be seen. Also, you should assume that you can see the entire sample, and that the sample is in a sealed box, so that no matter can enter or leave. Sample of Substance X Change 1 Change 1 is O impossible O O a chemical change a physical change Change 2 Change 2 is: impossible O a physical change O a chemical change Change 3 000 000 Change 3 is: O impossible O a physical change O a chemical change X

For each substance include its state of matter (using words, not symbols). Your sentences should include verbs (remember your telling a story). 1.) 2Ca(NO3)2(s) -> 2 CaO(s) + 4 NO2(g)+O2(g) 2.) ZnCl2(aq)+ 2 NaOH(aq) -> Zn(OH)2(s) + 2 NaCl(aq) 3.) Mg(s) + 2HCl(aq) -> MgCl(aq) +H2(g)

Supposed to magnesium feelings and sulfur or heat it so they react with each other forming magnesium sulfide what is the product in this chemical reaction would they still be a mixture why or why not
