Answer:
A They are attracted to a magnet
Products are the species formed from chemical reactions. During a chemical reaction reactants are transformed into products after passing through a high energy transition state. This process results in the consumption of the reactants.
Answer:
1. 3.02 liters
2. 302.2 liters
3. 2.83 grams
Explanation:
Question 1.
Let's convert the molarity in mass.
Molarity is mol/L, so if we convert the moles to mass, we are talking about a mass, in 1L of solution. (mol . molar mass)
0.5 mol . 110.98 g/m = 55.49 g
Now we can make a rule of three:
If 55.49 grams of chloride are in 1L of solution
then 167.5 g of chloride are in (167.5g . 1L) / 55.49 g = 3.02L
For question 2 and 3, we assume STP, where pressure is 1 atm and T° is 273K. - Standard conditions of temperature and pressure (STP)
Let's apply the Ideal gases law equation
P . V = n . R .T
1 atm . V = 13.5 moles . 0.082 l.atm / mol .K . 273K
V = (13.5 moles . 0.082 l.atm / mol .K . 273K) / 1 atm = 302.2 liters (question 2)
Question 3.
1 atm . 31.7 L = n . 0.082 l.atm / mol.K . 273K
(1 atm . 31.7 L ) / (0.082 l.atm / mol.K . 273K) = 1.41 moles → n
Let's convert moles to mass ( mol . molar mass)
1.41 mol . 2g/mol = 2.83 grams
Answer:
During electron capture, an inner electron usually from K shell or L shell combines with proton of the nucleus thereby changing proton to neutron. The process of electron capture is also accompanied by the emission of neutrino. It generally occurs in proton rich nucleus. The capture of electron by the proton creates a hole in the electron shell. The hole created is generally filled by the dropping down of a higher level electron with the emission of X -ray.
