100000 Cubic Millimetres is the answer
Answer:
0.844 mol Na
Explanation:
19.4 g Na x (1 mol Na/22.99 g Na) = 0.844 g Na
Explanation:
well I'm not 100% sure but I studied a little bit with rocks and crystals I've noticed that the hotter the temperature are it does not matter if it is Obsidian the hotter it is the more shinier it will become so the texture of it has to be a right temperature to be able to create a different texture such as a diamond and a diamond has to be compressed so hard that it will turn into diamond this is just an explanation please do not take this as a real answer I hope this help you though
Answer: chlorine gas
Explanation:
mass = 0.508 g volume = 0.175 L
From ideal gas equation.
PV = nRT
(1.0 atm) × (0.175 L) = n × [0.0821 atm L / (mol K)] × [(273.2 + 25.0) K]
n = 1.0 × 0.175 / (0.0821 × 298.2) mol
n = 0.00715 mol
Molarmass= mass/mole
Molar mass of the gas = (0.508 g) / (0.00715 mol) = 71.0 g/mol
The molar mass of Cl₂ (chorine) = 35.5 × 2 g/mol = 71.0 g/mol
Hence, the gas is chlorine.
The correct statement is that branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
The prime polysaccharide found in the plants, which is responsible for the structural role is cellulose. It is one of the most naturally abundant organic constituents found on Earth. It is an unbranched polymer of glucose residues, which is combined together through beta-1,4 linkages that permit the molecules to produce straight and long chains. The cellulose molecules are linear, rigid rods, which combines laterally into microfibrils.
