Answer:

9 grams of methane contains a greater number of hydrogen atoms (therefore molecules) than 10 grams of ammonia

Explanation:

The number of atoms of hydrogen per molecule of ammonia = 3 atoms of hydrogen

The number of atoms of hydrogen per molecule of methane = 4 atoms of hydrogen

The molar mass of methane = 16.04 g/mol

The molar mass of ammonia = 17.031 g/mol

The number of moles of methane in 9 grams of methane = 9/16.04 ≈ 0.561 moles

The number of hydrogen atoms in 0.561 moles of methane = 0.561 × 6.02 × 10²³ × 3 ≈ 1.351 × 10²⁴ atoms of hydrogen

The number of moles of ammonia in 10 grams of ammonia = 10/17.031 ≈ 0.5872 moles

The number of hydrogen atoms in 0.5782 moles of ammonia = 0.5872 × 6.02 × 10²³ × 3 ≈ 1.06 × 10²⁴ atoms of hydrogen

Therefore, 9 grams of methane contains a greater number of hydrogen atoms than 10 grams of ammonia.

Now, begin making changes. Remember to meet all of the president’s promises. What were the three largest cuts you made, and why
zzz [600]

Being made president the three cuts i would mare would be in the following areas, taxes, Government spending and cut unnecessary ministries or departments.  

The fist big cut I would make would be tax cuts, the reason for this is the less taxes are charged on the populaiton the more money said population will have to spend on goods and services adn thus circulate in the economy. This would also mean less tax breaks for the wealthly, thus removing their privileges of avoiding taxes through charities.

The second big cut I would make would be in government spending, or more specifically reducing or cutting the salaries of career politicians by 30% to 40%. This is becasue the government with is the largest spender of capital in any given country while being the lowest producer of capital and it is unsustainable to maintain large political salaries. With this cut it would not only alleviate the tax payer, but also free up remaining funds for health and educaiton.

Finally the last cuts I would make would be in the area of departments or ministries. While some such as the department of Agriculture and Interior incompatible and cannot be fused, other such as the departmetn of labour and Treasury can be fused, reducing the number of departments and thus overall government spending again.

These are the three be cuts I would make as President.

miv72 [106K]
This is an example of inductive reasoning. Inductive reasoning happens when you make broad generalizations from specific observations. In this example, it suggests that since they can see the islands (observation), they must be on the highway (generalization). Inductive reasoning might not always be as accurate in some cases as deductive reasoning.
