The molar mass of Ca(ClO4)2 is 239.1 g/mol.
Answer:
n = 11.45 mol
Explanation:
Given data:
Number of moles = ?
Volume of gas = 98 L
Pressure = 2.8 atm
temperature = 292 K
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
2.8 atm × 98 L = n × 0.0821 atm.L/ mol.K × 292 K
274.4 atm.L = n × 23.97atm.L/ mol
n = 274.4 atm.L /23.97atm.L/ mol
n = 11.45 mol
Owing to the arrangement of ions in NaCl, the structure has a high melting point and crystalline structure.
Ionic compounds are know to have a crystalline structure. This is because the ions in the compound are arranged into a crystal lattice. A crystal lattice gives a regular repeating structure of ions in the crystal.
As a result of this order in the crystal, the resultant sodium chloride structure has a high melting point and crystalline structure.

Answer :
will be 1 mole of
/ 125. 40 g of
Explanation : The molar mass and the formula units are the same thing in any compound so when given a molar mass of compound then one mole of that compound is divided by its molar mass. Where one mole will be equal to avogadro's number which is 6.022 X

Photosyntheis is a biochemical reaction that combines chemicals with biological species to produce energy. Atoms of hydrogen bond with carbon to form glucose.
<h3>What are the reactants and the products of the light reaction?</h3>
Carbon dioxide and hydrogen are the reactants that are used from the environment by the plants to make energy. Glucose and oxygen are the products.
The hydrogen atoms from the environment are absorbed by the plants and are combined with the carbon dioxide to yield glucose or sugar molecules for energy.
Therefore, option B. hydrogen and carbon dioxide react to produce glucose.
