<u>Answer:</u> The number of moles of strontium bicarbonate is 
<u>Explanation:</u>
Formula units are defined as lowest whole number ratio of ions in an ionic compound. It is calculate by multiplying the number of moles by Avogadro's number which is 
We are given:
Number of formula units of 
As,
number of formula units are contained in 1 mole of a substance.
So,
number of formula units will be contained in =
of strontium bicarbonate.
Hence, the number of moles of strontium bicarbonate is 
Answer:
an isotope consists of two or more forms of the same elements that contains equal number of protons but different number of neutrons in their nuclei but differ in relative atomic mass but not in chemical properties
The percentage of soil components of the soil is: inorganic components
-soil particles
-mineral elements = 45%
-water or moisture= 25%
- air= 25%
organic components
-humus or decayed organic matter= 5%
-living organisms
Answer:
A) 3.6 cm
Explanation:
Accuracy comes down to how precisely you can read the length on a given scale. Here since the smallest increment is centimeter, we can go only one decimal beyond to estimate. This is because you can usually estimate to only one decimal place beyond the closest marks on any measuring.
So, the answer should be 3.6 cm.

Hope that's right!
water <span>t because washing with sulfuric acid wouldn't actually get any
of the acid off of you, same with oil, just soothe it momentarily and
stop burning of the skin by creating a barrier to the acid. If you wash
with soap
it will burn even more by activating some enzymes in the acid (depending
on kind of acid) so washing with water is most practical because it
gets all of the acid off immediately to stop more burns from occurring. I
would recommend washing with water and then pouring oil onto the burn,
to create a barrier. </span>
