What does water offer that attracts human settlement?
Answer:
Water is a human necessity. Therefore, it is one of the first things a human settlement would need to have. A community cannot thrive without a water source.
Answer:
Water is a basic need that is more than a necessity, humans can't survive without water for more than a period of three days, And thus having water as available, creates a tendency among humans as humans like to get everything at ease so they tend to settle near the water bodies if possible.

hi can you balance the equation Fe + O2 = Fe2O3
Answer:
4Fe + 3O2→ 2Fe2O3
Explanation:
Fe + O2 → Fe2O3 is the unbalanced form of chemical reaction.
Balancing the simple molecules first, in this case the O2
Fe + 3O2→ Fe2O3 there are now 6 O atoms on the left, there must also be 6 O atoms on the right.
Fe + 3O2 → 2Fe2O3
Balance the rest of the equation.
4Fe + 3O2→ 2Fe2O3
how to find molar mass
Answer:
Multiply the element's atomic mass by the number of atoms of that element in the compound. This will give you the relative amount that each element contributes to the compound. For hydrogen chloride, HCl, the molar mass of each element is 1.007 grams per mole for hydrogen and 35.453 grams per mole for chlorine.
An object accelerates 5.0 m/s2 when a force of 12.0 newtons applied to it.What is the mass of the object?
Please help, I haven’t seen this question anywhere !
Also this is from my Science Class
Answer:
2.4kg
Explanation:
Newton's 2nd law tells us that force is equal to the mass of an object multiplied by its acceleration, or F = ma. We can solve this equation for mass by rearranging algebraically:
m = F/a
So:
m = (12.0N)/(5.0m/s2) = 2.4kg
WHAT ARE SOME POSSIBLE CONSEQUENCES IF A HUMAN BODY DOES NOT MAINTAIN
HOMEOSTASIS
Answer: If homeostasis is disrupted, it must be controlled or a disease/disorder may result.
Explanation: What happens if there's disruption? Your body systems work together to maintain balance. If that balance is shifted or disrupted and homeostasis is not maintained, the results may not allow normal functioning of the organism.

A halloon has a volume of 456 mL at a pressure of 1.0 atm. It is taken under water in
a submarine t a depth where the air pressure in the submarine is 3.3 atm. What is the
volume of the balloon? assume con- stant temperature.
According to Boyle's law, temperature being constant the volume of the balloon at pressure 3.3 atmospheres is 138.18 ml.
What is Boyle's law?Boyle's law is an experimental gas law which describes how the pressure of the gas decreases as the volume increases. It's statement can be stated as, the absolute pressure which is exerted by a given mass of an ideal gas is inversely proportional to its volume provided temperature and amount of gas remains unchanged.
Mathematically, it can be stated as,
P∝1/V or PV=K. The equation states that the product of of pressure and volume is constant for a given mass of gas and the equation holds true as long as temperature is maintained constant.
According to the equation the unknown pressure and volume of any one gas can be determined if two gases are to be considered.That is,
P₁V₁=P₂V₂
Substitution in above equation gives, V₂=1×456/3.3=138.18 ml.
Thus, the volume of balloon is 138.18 ml.

The characteristics of a certain gas are shown below.
Characteristics of a Gas
Characteristic Description
Compound Oxygen gas
Condition STP
Mass 4.8 grams
What is the expected density of the above sample of gas?
A. 1.90 g/L
B. 1.82 g/L
C. 1.56 g/L
D. 1.43 g/L
Answer:
1.56g/L it will be as per my calculation if I am not wrong so
Answer: D: 1.43
The expected density of the given sample of oxygen gas at STP can be calculated using the ideal gas law equation:
PV = nRT
where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.
At STP, the pressure is 1 atm and the temperature is 273 K. We are given that the mass of the oxygen gas is 4.8 g. To find the number of moles of oxygen gas, we can use its molar mass, which is 32.00 g/mol:
n = mass / molar mass = 4.8 g / 32.00 g/mol = 0.15 mol
Using the molar volume of an ideal gas at STP, which is 22.4 L/mol, we can find the volume of the oxygen gas:
V = n × molar volume = 0.15 mol × 22.4 L/mol = 3.36 L
Therefore, the expected density of the given sample of oxygen gas at STP is:
density = mass / volume = 4.8 g / 3.36 L = 1.43 g/L
Therefore, the expected density of the given sample of oxygen gas at STP is 1.43 g/L.
