Answer:
0.5 g/mL----- float
1.0 g/mL---- float
2.0 g/mL-----sink
Explanation:
Those objects will float whose density is less or equal to water density due to lower mass while those object will sink whose density is greater than water because the mass of the object is greater than water. So the density of the object i. e. 0.5 g/mL and 1.0 g/mL will float in the liquid because its density is lower than water which is 1 g/mL while the density of an object i. e. 2.0 g/mL is denser than water so it will sink.
Answer:
It's D
Explanation:
Sorry for the late answer. Since the squirrel ran constant speed for 10 seconds and it ran 20 meters the first point would be at (10,20) then since it stopped to rest for 15 seconds the next point would be (25,20) finally since it ran another 30 meters for 15 more seconds the next point would be at (40,50). Sorry if the answer isn't the best, i'm bad at explaining ;w;
<span>The
scientist thought that the atom was the smallest particle in the universe is
John Dalton. He established the atomic theory which
consists of five; elements are made of extremely small particles called atoms,
atoms of different element have different sizes, mass and physic – chemical
properties, atoms cannot be divided further, destroyed or created, atoms can
combine to form compounds and in chemical reaction, atoms can be combined,
separated or rearranged</span>
The chemical formula for ammonia is NH3. So first, you need to find the molar mass of ammonia (how many grams in one mole).
N=14g
H3=3g
So one mole of NH3 is 17 grams, you can divide 82.9 grams by 17 grams to find the number of molecules. The answer should be 4.876 moles (molecules) of ammonia. Hope this helps!
