Answer:
Explanation:
From the given data on the table, I can easily say my weight is a function of the acceleration due to gravity at anywhere in the universe.
Weight is given as
W = mg
m is the mass and g is the acceleration due to gravity.
Weight for a mass of 65kg would be the heighest on the surface of jupiter and it would be lowest on merury and mars due to their low value of g.
Answer:
The conclusion is that the mass is independent of gravity. However, the weight depends on the gravity value.
Explanation:
We have a girl with a mass of 65 kg. The picture has the gravity value for different planets. Weight (W) of a body is the product between the mass (M) and the gravity (g).
W = M*g.
According to the information we can mention that the weight of the girl will vary in all the planets. The highest weight will be for the highest gravity value of Jupiter with 25.9 m/s2. The lowest weight will be for Mercury and Mars with a gravity value of 3.7 m/s2.
It is important to mention that the mass of the girl will be the same in all the planets. However, the weight will vary according to the gravity variations.
Finally, The conclusion is that the mass is independent of gravity. However, the weight depends on the gravity value.
Answer: a
Explanation: a naturally occurring, inorganic solid that has a crystal shape and a definite chemical composition" is the one among the following choices given in the question that is the correct definition of minerals. The correct option among all the options that are given in the question is the first option. I hope it helps you.
Answer:
Ok; first of all, you must correct the Molecular Formula; FeSO4•7H20
So, work out the Molar Mass;,
(4x18)O+ 55.? Iron + 32 Sulphur, PLUS
(7x 18) H2O = 1 molar mass.
Now, take that times 5.24, show your work & check the Mol. Weights, I am going by memory.

Explanation:
B) Northern Florida would need snow for at least a week for this to be true.
C) The climate of northern Florida would be unaffected since it is already warm in Florida.
D) Jason does not realize that Southern Florida would also need to receive snow to make this true.
Jason is mistaken in equating a one-time weather event, such as snow in northern Florida, with climate change. Weather is short-term and local, whereas climate represents long-term regional patterns. An isolated weather occurrence does not contradict the extensive evidence of global climate change.
Jason has confused a singular weather event with the overall climate in his reasoning. The correct statement that explains what is wrong with Jason's reasoning is:
A) Jason has confused the weather for one day with the climate of a region.
Weather refers to short-term atmospheric conditions in a specific area, such as a snowy day in northern Florida. Climate, on the other hand, is the average weather in a region over a long period, typically taken over 30 years. A single instance of snow in a typically warm region does not refute the evidence of global climate change. It's the long-term trends and patterns, not isolated incidents, that indicate climate change. Therefore, the occurrence of snow in northern Florida is simply an irregular weather event and not an indicator of the overall climate or a disproof of global climate change.

Answer: C
Explanation:
a) How many grams of iron can be made from 6 moles H2
223.4 g of iron can be formed from 6 moles of hydrogen gas.
Explanation:
Fe₂O₃(s) + 3 H₂(g) → 2 Fe(s) + 3 H₂O(l)
Since the given equation is the balanced one, we need 3 moles of hydrogen gas to make 2 moles of iron, so the molar ratio is 3:2. So, from 6 moles of hydrogen gas, we can make few moles of iron as,
Molar mass of iron = 55.85 g
So amount of iron produced = 4 moles × 55.85 g/mol = 223.4 g of iron
