Mrrafil [7]3 years ago
5 0

Answer:

Protons, neutrons, and electrons

Explanation:

protons- a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign.

neutrons- a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.

electrons- a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.

A chemist is making 200 l of a solution that is 62% acid. he is mixing an 80% acid solution with a 30% acid solution. how much o
Savatey [412]
Answer: 72L of 30% and 128L of 80%

You can determine the weight of the acid by multiplying the concentration with the volume. Let say v1 is the volume of 30% solution needed and v2 is the volume of 80% solution.
The weight of acid from the used solution should be equal to the product. You can get this equation
final solution= solution1 + solution2
200l * 62%= v1 * 30% + v2*80%
124L= 0.3v1 + 0.8v2
124L- 0.3v1= 0.8v2
v2=155L- 0.375v1

The total volume of both should be 200l. If you use the previous equation, you can calculate:
v1+v2=200L
v1+ (155L- 0.375v1)= 200L
0.625v1= 200L - 155L
v1= 45/ 0.625= 72L


v1+v2=200L
v2= 200L- 72L= 128L

The area of a telescope lens is 7903 rnrn2 {a) What is the area in square feet (ft2)? (b) If it takes a technician 45 s to polis
LekaFEV [45]

Answer:

Area is 0.08504ft^{2} and 2.6\times 10^{3}s are needed for polishing

Explanation:

(a) ft is unit of F.P.S system whether mm is unit of M.K.S system.

According to unit conversion, 1mm=0.00328ft

So, 1mm^{2}=(0.00328)^{2}ft^{2}=1.076\times 10^{-5}ft^{2}

hence, 7903mm^{2}=7903\times 1.076\times 10^{-5}ft^{2}=0.08504ft^{2}

So, area of telescope lens is 0.08504ft^{2}

(b)135mm^{2} are polished in 45s

So, 7903mm^{2} are polished in \frac{45\times 7903}{135}s or 2.6\times 10^{3}s
