A polyatomic ion is a charged combination of individual atoms. The combination is regarded as a single unit when considering reactivity with other elements. Example: OH- which is a polyatomic ion made from one oxygen and hydrogen atom to form the negative hydroxide ion.
Answer
1.5x10^-3 m
24.91x10^5
Explanation:
15 millimeters
- 1 mm = .0015
exponent indicates which way the decimal moved and to how many places
we moved the decimal backwards (negative) 3 spaces
2491 km= 2491000 m
exponent indicates which way the decimal moved and to how many places
we moved the decimal forwards (positive) 5 spaces
2491000.00 --> 24.91000
After reacting, place a red moist litmus paper into the final solution and the litmus paper will turn blue. This indicates that the solution is alkaline.
Alternative methods
Using universal indicator
using phenophtalein
using bromothyl blue
using methyl orange
use pH probe connected to a data logger
Answer:
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. ... As the sinking plate moves deeper into the mantle, fluids are released from the rock causing the overlying mantle to partially melt.
