Answer:
v = 660 miles per hour
Explanation:
Given that,
The distance covered by the airplane is 1650 miles
Time taken by airplane is 2 hours 30 minutes
We need to find the average speed of the airplane. The total distance covered divided by total time taken is called the average speed of an object.
We know that,
1 hour = 60 minutes
⇒ 30 minutes = 0.5 hour
So,
Hence, the average speed of the airplane is 660 miles per hour.
Answer:
Mgf2 Bond type
Therefore, one Mg2+ needs two F– ions to balance. The 2+ of the Mg is balanced by having two -1 charged ions. Therefore, the formula of the compound is MgF2. The subscript two indicates that there are two fluorines that are ionically bonded to magnesium.

3.4 mol HCl * ( 36.46 g / 1 mol ) = 123.964 g HCl = 1.2 x 10^2 g HCl
Convert moles of HCl to grams of HCl using the molar mass ( 36.46 g/mol ).
Revise your answer to have the right number of significant figures ( 2 significant figures in this case, as determined by the the number of figures in the value with the least figures).
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
