Answer:
5.36 moles
Explanation:
From the given chemical equation, we see that one mole of nitrogen gas reacts with 3 moles of hydrogen gas in terms of mass.
Molar mass of hydrogen gas ; H2 = 2.016 g/mol
Molar mass of nitrogen gas; N2 = 28.01 g/mol
Thus;
28.01 grams of nitrogen gas requires 3 moles of hydrogen gas
Thus;
28.01 grams of nitrogen gas requires 3 moles of hydrogen gas
Therefore, 50 g of nitrogen gas will require; (50 × 3)/28.01 = 5.36 moles
V = 500ml = 0,5 l
c = 0,75 M
c = n/V
n = c × V
n = 0,75 × 0,5 = 0,375[mol]
M NaCl = 58,5 g/mol
1 mol ------- 58,5 g
0,375 mol ----- x g
x = 0,375 mol × 58,5 g / 1 mol = 21,94 g
Answer: In this solution there are 21,94 g of sodium chloride.

<span>observation
They utilize and make use of the scientific method in order to have clear basis and evidence for their investigations. Research method is always used to answer every scientific inquiry and in gaining evidential data or knowledge. The scientific method has the following process or at least undergoes the process of
1. Observation</span>
2. Hypothesis
3. Experimentation
4. Interpretation of data
5. Evaluating the data
6. Passing and recording the data
<span>These steps are crucial and the empirical data that these scientists obtain are very important to keep that is why research paper, thesis and dissertations exists.<span>

Answer:
2. Ne
Explanation:
Neon is an element. You cannot break down an element by chemical means.
1, 3, and 4 are wrong. They are all compounds, and compounds can be broken down by chemical means.
