Negatively charged toner is attracted to a positively charged image

These negatively charged particles are attracted to the positively charged regions on the drum/belt (remember opposite charges attract). A blank sheet of paper is passed over the charged wire making it positive and then passed over the drum/belt. The positively charged paper attracts the toner off the drum/belt.Your welcome

October 15, 2018 at 1:49 PM Dioxybenzone is a compound found in sunscreen, and only contains carbon, oxygen, and hydrogen. Analy

-Dominant- [34]

Answer:

Molecular formula for Dioxybenzone is C₁₄H₁₂O₄

Explanation:

Percent composition:

In 100 g of compound → 4.92 g are H

In 100 g of compound → 26.8 g are O

In 100 g of compound → 68.28 g are C

Let's convert the mass to moles by molar mass:

4.92 g / 1 g/mol = 4.92 moles H

26.8 g / 16 g/mol = 1.67 moles O

68.28 g / 12 g/mol = 5.69 moles C

Now we can apply a rule of three:

100 g of compound have 4.92 moles H, 1.67 moles O, 5.69 moles C

244.25 g of compound must have:

(244.25 g . 4.92 m) / 100 g = 12 moles H

(244.25 g . 1.67 m) / 100 g = 4 moles O

(244.25 g . 5.69 m) / 100 g = 14 moles of C

How many grams of Copper are in 500grams of Cu2CO3?

Novay_Z [31]

Answer:

≈170.22 [gr].

Explanation:

1) M(Cu₂CO₃)=2*64+12+3*16=188 [gr/mol];

2) the part of copper in Cu₂CO₃ is:

$\frac{64}{188} =\frac{16}{47};$

3) 16/47% of 500 [gr] is:

$500*\frac{16}{47}=170.22[gr].$
