Answer;
= 18.24
Explanation;
The ratio of N and O in the formula NO2 IS 1:2
Mass of nitrogen gas is 0.500 g
Moles of nitrogen will be;
= 0.500/16 = 0.03125 moles
Therefore;
The moles of Oxygen from the ratio will be;
= 0.03125 × 2 = 0.0625 moles
But; 0.0625 moles is equal to 1.140 g of Oxygen
The atomic number (mass in 1 mole) will be;
= 1.140 /0.0625
= 18.24
Thus the atomic number of Oxygen from the data is 18.24
<span>Since the answer is in grams, kilograms must first be converted to grams. A kilogram is equivalent to 1000 grams. Therefore, multiply 1.2 kilograms by 1000 and you get 1,200 grams. Then, calculate the number of hours in 5 days. Each day is 24 hours and 24 hours multiplied by 5 days equals 120 hours. Lastly, since the answer is in grams per hour, divide 1,200 grams by 120 hours and the resultant rate of reaction is 10 g/hr.</span>
Answer:
Explanation:
In KCL, the elements to combine to form KCl are K and Cl.
Potassium (K) is an element of group 1 and they're known to have 1 valence electron in its outer most orbital. This electron is donated and used for bonding. It is every element desirability to attain octet or duet electronic configuration I.e by having 2 electrons or 8 electrons in its outer orbital. Potassium has a lower electro negativity and higher ionization energy, hence it is easier to donate electron than to recieve it. Meanwhile, Chlorine (Cl) is an element of group 17 which are characterized for having 7 electrons in its outermost orbital requiring just one electron to form an octet configuration, chlorine has a higher electro negativity and lower ionization energy hence it is easier to accept electron than to donate it.
The nature of bond formed from K and Cl to give KCl is called electrovalent bonds.
Equation of reaction
K + Cl → KCl
The pressure of the gas would be the dividend divided by the number of the second vi~2
