Answer:

It helped biologists collect data on when and where turtles travel.

Explanation:

Green sea turtles need to be conserved so the biologist take help of satellites in order to track down green sea turtles.

The tracking of green sea turtles can be done by the help of satellites as satellites send a signal whenever these turtles come to surface of water to breathe which can then be used to prevent the turtles from getting caught by poachers.

In the reaction of iron water shown below what coefficient must be placed before the iron to balance the reaction fe+4h2o fe3o4

tiny-mole [99]

Answer is: three.
Unbalanced chemical reaction: Fe+4H₂O → Fe₃O₄ + 4H₂.
Balanced chemical reaction: 3Fe+4H₂O → Fe₃O₄ + 4H₂.
In balanced reaction, there is three iron atoms on the left and on the right, eight hydrogen atoms and four oxygen atoms on both side of chemical reaction.

A chemist decomposes several samples of water into hydrogen and oxygen and weighs or more correctly measures the mass of the hyd

MariettaO [177]

Answer:

A. Hydrogen and oxygen combines in a constant mole ratio in all the three water samples

B. Carbon and oxygen are combined in a constant mole ratio in all the three samples of carbon dioxide

C. All pure samples of a compound contain the same elements combined in the same proportion by mass

D. Since the same elements are always combining to form a certain compound, and the atoms of each element has its own mass, the atoms of each element combining to form the compound do so in a fixed proportion by mass.

Explanation:

A. molar mass of hydrogen = 1.0 g/mol; molar mass of oxygen = 16 g/mol

The molar ratio of elements in a compound gives the proportion each element is combined with the other by mass.

molar ratio of hydrogen to oxygen in the samples:

Sample 1: Hydrogen; 1.5/1 = 1.5: Oxygen; 12/16 = 0.75

molar ratio = 1.5/0.75 = 2 : 0.75./0.75 = 1

molar ratio = 2:1

Sample 2: Hydrogen; 2/1 = 2: Oxygen; 16/16 = 1

molar ratio = 2/1 = 2 : 1/1 = 1

molar ratio = 2:1

Sample 3: Hydrogen; 2.5/1 = 2.5: Oxygen; 20/16 = 1.25

molar ratio = 2.5/1.25 = 2 : 1.25/1.25 = 1

molar ratio = 2:1

Hydrogen and oxygen combines in a constant mole ratio in all the three water samples

B. molar mass of carbon = 12 g/mol; molar mass of oxygen = 16 g/mol

molar ratio of carbon to oxygen in the samples:

Sample 1: Carbon; 0.5/12 = 0.04 : Oxygen; 1.3/16 = 0.08

molar ratio = 0.04/0.04 = 1 : 0.08/0.04 = 2

molar ratio = 1:2

Sample 2: Carbon; 1.0/12 = 0.083 : Oxygen; 2.7/16 = 0.168

molar ratio = 0.083/0.083 = 1 : 0.168/0.083 = 2

molar ratio = 1:2

Sample 3: Carbon; 1.5/12 = 0.125 : Oxygen; 4.0/16 = 0.250

molar ratio = 0.125/0.125 = 1: 0.250/0.125 = 2

molar ratio = 1:2

Carbon and oxygen are combined in a constant mole ratio in all the three samples of carbon dioxide

C. All pure samples of a compound contain the same elements combined in the same proportion by mass

For the reaction of 2Na2O, if you have 18.0 g of Na, how many grams of O2 are needed for reaction?

geniusboy [140]

Answer: -

6.26 grams

Explanation: -

Atomic Mass of sodium Na = 23 gram

Mass of Na = 18 g

Atomic mass of oxygen O = 16 gram

Molar mass of O2 = 16 x 2 = 32 gram

The balanced chemical equation for the reaction is

4 Na + O2 -- > 2 Na 2 O

From the balanced chemical equation, we see

4 Na requires 1 O2

4 x 23 gram of Na requires 32 gram of O2

18 g of Na gives $\frac{32 g O 2 x 18 g Na}{4 x 23 gram Na}$

= 6.26 grams of O2

For the reaction of formation of Na2O, for 18.0 g of Na, 6.26 grams of O2 are needed for reaction.

Temperature of the water to the nearest degree: °C

Elena L [17]

Answer:

2°C.

Explanation:

Considering the thermometer used in this case, we can see that there are 5 lines counting from 0 to 10.

It therefore means that 1 line indicates 2°C.

With the above insight, the thermometer reads 2°C.

Therefore, the temperature of the water is 2°C.

The neutron is found at?

Tanya [424]

The answer is: nucleus of an atom.

Neutron (n°) is a subatomic particle with no net electric charge.

Protons and neutrons are found in nucleus of an atom (atomic nuclei).

They are called nucleons and have masses of approximately one atomic mass unit.

Mass number (A) is sum of protons and neutrons in nucleus of an atom.

Protons and neutrons are hadrons composed of three valence quarks.
