The number of electrons in the outermost shell determine the reactivity.
Answer:
18.
Explanation:
1) according to the reaction (M(Fe)=56; M(O₂)=32; V₀=22.4):
4Fe+3O₂⇒2Fe₂O₃; - ν(O₂)=0.75*ν(Fe);
2) ν(Fe)=m(Fe)/M(Fe)=60/56≈1.071 [mol];
3) ν(O₂)=0.75*1.071=0.804 [mol];
4) V(O₂)=V₀*ν(O₂); ⇒ V(O₂)=22.4*0.804=18 [lit].
The distance between a carbon atom and an oxygen atom in the co molecule is 0.63
<h3>What is the distance?</h3>
Distance is the measurement of the farness of two objects from each other.
The distance between the molecules can be calculated by the given formula
Putting the values in the equation
Thus, the distance between a carbon atom and an oxygen atom in the co molecule is 0.63

Answer:
The base-10 value of 76(10 )
is equal to base-2 value of 10011002.
Explanation:
Step 1) Divide 76 by 2 to get the Quotient. Keep the Whole part for the next step and set the Remainder aside.
Step 2) Divide the Whole part of the Quotient from Step 1 by 2. Again, keep the Whole part and set the Remainder aside.
Step 3) Repeat Step 2 above until the Whole part is 0.
Step 4) Write down the Remainders in reverse order to get the answer to 76 as a binary.
Here we will show our work so you can follow along:
76 / 2 = 38 with 0 remainder
38 / 2 = 19 with 0 remainder
19 / 2 = 9 with 1 remainder
9 / 2 = 4 with 1 remainder
4 / 2 = 2 with 0 remainder
2 / 2 = 1 with 0 remainder
1 / 2 = 0 with 1 remainder
Then, when we put the remainders together in reverse order, we get the answer. The decimal number 76 converted to binary is therefore:
1001100

V = 25 x 12 x 13
V = 3900 cm³
Militers:
1 cm³ = 1 mL therefore : 3900 mL
hope this helps!
