Step-by-Step Text Solution:1. Definition of a Mole: A mole is defined as the amount of a substance that contains exactly \(6.022 \times 10^{23}\) elementary entities of that substance.2. Under
Water can be viewed as a renewable resource but to some extent, this resource is non-renewable since accessibility to clean water may be limited. There are various sources of water. These sources include: Rain. Rivers. Lakes and oceans....
What is the molar heat capacity of water?Molar heat capacityThe molar heat capacity is the amount of energy which is required to raise the temperature of one mole of a substance by one degree and its SI unit is J/mol.Answer and Explanation: ...
1 mole of water is heated by 1C°. The increased thermal energy makes additional microstates accessible. (The increase is by a factor of about 1020,000,000,000,000, 000,000,000.) Equal volumes of two gases are allowed to mix. The effect is the same as allowing each gas to expand to...
The tunnels of one naked mole rat colony can cover as much land as twenty football fields. 大西洋海鹦在洞穴中饲养小海鹦。他们在靠近水的悬崖上挖洞,在洞里放上海藻、植物或羽毛,海鹦父母轮流照顾一条腿,直到它孵化出来,然后父母中的一方离开,去找小鱼喂...
Calculate the number of aluminium ions present in 0.051 g of aluminium oxide. (Hint: The mass of an ion is the same as that of an atom of the same element. Atomic mass of Al = 27 u) View Solution What is the mass of 0.5 mole of water (H2O). (Atomic masses : H=1u,O=16...
number (6.02214076 × 1023) is the number of molecules that constitutes the atomic weight of a molecule in grams (g). For example, water is two hydrogen atoms with a weight of 1 g each and one oxygen atom with a weight of 16 g, meaning that one mole of water molecules weighs 18 g...
What is the mass of 1 mole of a raindrop? Mole: The Mole is a unit that represents a certain number. It is defined as the number of carbon atoms contained in a pure sample carbon-12 of mass12g. The constant number of called the Avogadro's constant. The order of the magnitude of ...
“My favorite Harry Styles memory was when he helped me rescue a baby mole that my cats had brought into the house, and it had burrowed underneath the carpet,” recalls tour guide Jill Booth, 58, who, as a former neighbor with a son the same age, has known Styles since he was a yo...
Today, a mole isAvogadro's numberof particles, which is exactly 6.02214076×1023. For all practical purposes, the mass of one mole of a compound in grams is approximately equal to the mass of one molecule of the compound in daltons. ...
