The answer is mid ocean ranges:)
1) State the balanced chemical reaction
H2SO4 + 2NaOH -> Na2SO4 + 2H2O
2) State the molar ratios:
1 mol H2SO4 : 2 mol NaOH
3) Set the proportions using the number of moles of one rectant and x for the unknown one>
1 mol H2SO4 / 2 mol NaOH = x mol H2SO4 / 0.75 mol NaOH
=> x = 0.75 mol NaOH * [1 mol H2SO4 / 2 mol NaOH]
x = 0.375 mol H2SO4
4) Calculate the mass using the molar mass of H2SO4, MM.
MM = 2*1g/mol + 32.1 g/mol + 4*16 g/mol = 98.1 g/mol
mass = # of moles * molar mass = 0.375 mol * 98.1 g/mol = 36.79 g.
Answer: 36.8 grams
To separate it you would use a type of powder or corn starch
Answer:
a. 226/88Ra --> 222/86Rn + 4/2He
Explanation:
Alpha decay you lose four from the mass number and two from the Atomic number. Giving you 222 mass and 86 atomic. Radon has 222 mass and 86 atomic 222/86Rn + the four from the mass we took and the two from the atomic we took. What element has 4 mass and 2 atomic. Helium 4/2He
here is what came up when i searched it up:
"The attraction between protons and electrons can also make clothes stick together in the dryer. When you dry clothes in the dryer, different fabrics rub together, and electrons from a cotton sock (for instance) may rub off onto a polyester shirt."
