Answer:
It is both accurate and precise.
Explanation:
Accuracy and precision are two ways data measurements are described. A measurement is said to be ACCURATE if it is close to the accepted/correct value while PRECISE measurements are those measurements that are close to one another.
In this case, the correct value is 59.2
From observation of the experimental values:
Trial 1: 58.7
Trial 2: 59.3
Trail 3: 60.0
Trial 4: 58.9
Trial 5: 59.2
- One would notice that these measurements in each trial is close to the correct value of 59.2, hence, they are said to be ACCURATE.
- Also, the measurements are close to one another, hence, they are said to be PRECISE
in a nutshell, the data is both accurate and precise
Well all 3 it would start with a producer,
example:
African Iris- African Killer Bee- Anteater- Spotted Hyena-(when the hyena dies of natural causes since it is an apex predator)- Earthworm
I don't know if this is exactly what you mean, but this is the best example I can with.
Answer;
A. a substance that releases hydrogen ions in water
C. a substance that tastes sour
E. a substance with a pH below 7
Explanation;
The properties of an acid includes;
-An acid is any substance that releases hydrogen ions, H⁺, into water.
-Sour taste (lemons, limes, and vinegar are acidic) .
-Blue litmus paper turns RED in the presence of hydrogen ions; blue litmus paper is used to test for acids
.
-They have a pH value less than 7
.
-They neutralizes/reacts with bases to give salt and water.
Observe the absence of magnetic rocks in locations that do not match the poles.
Answer:
a) (SO4)2 + Ba2 = BaSO4
b) (CO3)2 + 2H = H2O + CO2
c) NH4 + 2Na = Na + 2N + 2H
There u go :D
