How can the scientists observe far objects which are thousands of light years away? What is the difference between an open and a globular star cluster? Explain the motion of galaxies. In what specific way does light from distant stars and galaxies tell astronomers that atoms ...
How do we know that matter is composed of atoms? Describe collision theory. Explain the synthesis reaction of the Haber process in terms of the collision theory How are hydrogen atoms separated from water? Define and explain what are line spectra, and where do they come from?
The formula for a compound in which the number of different constituent atoms is represented by a simplest whole-number ratio is called the empirical formula for the compound.Answer and Explanation: Become a Study.com member to unlock this answer! Create your account View...
Explain how the shapes of carbohydrates, lipids, and proteins relate to their functions. What are the three kinds of atoms present in carbohydrates? Give an example of each type of simple carbohydrate and complex carbohydrate. What are the basic building blocks of carbohydrates?
Haemoglobin (Hb) is the protein that transports oxygen in mammals.Hb is 0.342% Fe by mass and each Hb molecule contains four iron atoms.Calculate the molar mass of Hb. A mass of 0.1156g of a substance that is composed of carbon,hydrogen and nitrogen is reacted with oxygen.Carbon dioxide...
H2S is so efficiently photolysed by the irradiating Solar flux that the profile always remains consistent with the inferred upper limit at the cloud top (with the H atoms liberated forming H2, and the sulfur atoms liberated mainly forming sulfur allotropes, Sxforx = 1, . . . ...
I don't see how the box containing dark matter is at all consistent with the premise of dark matter being primordial black holes. PBHs wouldn't be ubiquitously distributed through space such that any given volume contains a constant tiny number of them, would they? Black holes that are that...
1A). The overall SHP2/T507K structure is similar to the previously reported WT SHP2 structure (PDB code 4DGP) (12) with a root-mean-square deviation (RMSD) value of 1.423 Å for 486 Cα atoms between the two structures. However, the conformations of two surface loops in SHP2/T507...
How Atoms & Molecules Form Solids: Patterns & Crystals from Chapter 2 / Lesson 5 41K When atoms and molecules condense into tightly packed rows, they create solids. Learn about the different mixtures and crystal patterns that form to create solids, suc...
Elements are pure substances composed of only one kind of atom. They combine with other elements to form the compounds. The combination of elements is a results of the interaction of their valence electrons. The structures of the elements can be represented using Lewis dot structures which show ...
