Answer:
Step-by-step explanation:
a. 960 / 4 = 240 for 1 grid
1/2 cm = 24000
1 : 48000
b. A to C
AC² = 3² + 6²
AC² = 9 + 36
AC²= 432 + 1728
AC² = 2160
AC = √2160 km
Answer:
3
Step-by-step explanation:
Explanation:
Although you have not been provided with direct masses, you can use the percentage composition values in place of masses.
First, calculate the number of moles of each element:
This is the formula for the ionic compound calcium carbonate, confirming that our result is indeed in the magnitude of a plausible answer. In fact, given the fact that calcium carbonate is ionic, it is also true that this empirical formula equates to the unit formula of the compound.
Answer:
okay the question
