We can use the atomic model to demonstrate the ways in which scientists refine and build off each other's findings because of the fact that once this model was created, it brought with it other models and inventions, such as the periodic table and other theories about our known universe.

Answer:

I cant answer B, but I can answer A, and I don't think it is  a scientifically reasonable plan.  

Explanation:

The bag of sand weighs less than the gold statue, and yes the bag of sand seems like it would keep the trap from activating, but you would scientifically have to put something that was the same weight as the gold statue on the pedestal that the statue is on.

2HCI + Na, so, - 2NaCl + H,so,
Tems11 [23]

Answer:

None of the options are correct.

The correct answer is 1.10g

Explanation:

First, we'll begin by balancing the equation given above. This is illustrated below:

2HCl + 2Na —> 2NaCl + H2

Next, let us calculate the mass of HCl that reacted and the mass of H2 produced from the balanced equation. This is illustrated below:

Molar Mass of HCl = 1 + 35.5 = 36.5g/mol

Mass of HCl from the balanced equation = 2 x 36.5 = 73g

Molar Mass of H2 = 2x1 = 2g/mol

Now we can easily find the mass of H2 produced when 40g of HCl reacted as shown below:

From the balanced equation,

73g of HCl produced 2g of H2.

Therefore, 40g of HCl will produce = (40 x 2)/73 = 1.10g of H2.

From the calculations made above,

40g of HCl produced 1.10g of H2
