The doctor required a 15% 750mL solution. To lower the concentration of the solution, you have to add more diluting liquid.
750mL * 0.15 = 112.5mL. This 112.5mL signifies the pure chemical or compound in the solution. This 112.5mL can be taken from the stock solution.
112.5 * 2 = 250mL of stock solution would be needed and 500 mL of the diluting agent should be added. Adding the two together would result to a 750mL solution of 15% concentration.
Answer:
Jodi is violating two rules; She is not wearing any safety equipment and managed to catch fire to herself. She is also not wearing gloves or safety goggles like the other two. Kimberly is leaving fire unattended, and can cause many accidents and if chemicals come in contact in the wrong way, it could be catastrophic. Kimberly is also carelessly using a fire extinguisher carelessly and chemicals in the can cause accidents.
Explanation:
I hope this helps <3
The formula to be used for this problem is as follows:
E = hc/λ, where h is the Planck's constant, c is the speed of light and λ is the wavelength. Also 1 aJ = 10⁻¹⁸ J
0.696×10⁻¹⁸ = (6.62607004×10⁻³⁴ m²·kg/s)(3×10⁸ m/s)/λ
Solving for λ,
λ = 2.656×10⁻⁷ m or <em>0.022656 nm</em>
This is a synthesis reaction, where 2 reactants combine to form a single product.
In decomposition, 1 reactant splits into 2 products.
In single replacement, one element swaps with another, in the form A + BC = B + AC.
In double displacement two elements swap, in the form AB + CD = AD + CB
In neutralization (a kind of double displacement), an acid and a base react to form water and a salt.
