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.

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

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?

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

Only typed explanation

Two or more substances in variable proportions, where the composition is constant throughout are a compound. an element. a heterogeneous mixture. a homogeneous mixture. a crystalline solid.

• Sucrose: C12 H22O11 • Copper (I) Chloride: CuCl • lodine: I2 • Potassium lodide: KI Our goal is to try to find a pattern for which compounds conduct electricity when dissolved in water, and which don't. One hint is to look for patterns in which kinds of atoms form substances that conduct when dissolved, and which kinds of atoms form substances that don't conduct when dissolved.

Consider these compounds: A. Ba3(PO4)2 B. Ca3(PO4)2 C. PbCrO4 D. CaCrO4 Complete the following statements by entering the letter(s) corresponding to the correct compound(s). (If more than one compound fits the description, include all the relevant compounds by writing your answer as a string of characters without punctuation, e.g, ABC.) Without doing any calculations it is possible to determine that barium sulfite is more soluble than fill in the blank 1, and barium sulfite is less soluble than fill in the blank 2. It is not possible to determine whether barium sulfite is more or less soluble than fill in the blank 3 by simply comparing Ksp values.

The study of the structure of a material can be carried out at four different levels. The first is the subatomic level, which studies the atom individually and the behavior of its nucleus and electrons. The second level is the atomic level, which studies the interaction between several atoms and the formation of bonds and molecules. The third level is the microscopic level, which corresponds to the atomic and molecular arrangements and the formation of crystalline, molecular, and amorphous structures. Finally, the macroscopic level relates to the material's behavior in service. (CALLISTER JR., W. D.; RETHWISCH, D. G. Materials Science and Engineering: An Introduction. 8th ed. Rio de Janeiro: LTC Publisher, 2013). Regarding the basic concepts of materials science, mark the correct option: One of the basic concepts of materials science concerns how the atoms, molecules, or ions that constitute a material are spatially organized. This is the concept of material composition. Basic…
