Stainless steel is an alloy of iron containing 5 percent nickel and 0.175 percent chromium. How many atoms of nickel are present
erica [24]
First you need to work out what mass of 84g of stainless steel is nickel, and because there's 5% you can simply divide by 20, giving 4.2g

For this you can use the equation Moles= \frac{Mass}{Mr}

The mass, as was worked out previously, is 4.2g
The Mr, which is found on the periodic table, is 28

Moles = \frac{4.2}{28} = 0.15mol

1mol = 6.023 x 10^{23} atoms

So, 0.15mol = 0.15 x 6.023 x 10^{23} = 9.0345 x 10^{22} atoms

slavikrds [6]
The answer would be A will increase and T <span>will decrease.

The product of this reaction emits red light because it absorbs green and blue light. As the reaction occurs, the concentration of the product increase. This will makes absorbance of green and blue light increases and the solution will become redder.</span>

Answer:

Explanation:

When you divide exponentials, you subtract the powers. For the numbers infront, just use a basic calculator for.
