Answer : A - Infrared

11. As the Sun's radiation passes through the atmosphere, some of it is reflected back into space.

12. About 25% of Incoming solar radiation is reflected back to space by clouds and tiny particles in the air.

13. Another 5 percent is reflected back into space by land and sea surfaces.

14. Only about 20 percent of incoming solar radiation reaches and is absorbed by Earth's surface.

15. The Sun's Energy is responsible for Climate and Weather.

2AgNO3+K2CrO4⇒Ag2CrO4(s)+2KNO3
Hence by mixing 0.0024M AgNO3 and 0.004M
K2CrO4, we will have Ag2CrO4 which is precipitated out and leave us with
0.0024M KN03 which is mixed with (0.004-0.0024/2)M, it can be 0.0028M, of K2Cr04

A sample of lemon juice has a pH of 3. What is the [OH-] concentration of the lemon juice? A) 11 B) 1 X 10+3 C) 1 X 10-3 D) 1 X

Likurg_2 [28]

pH scale is used to determine the acidity of a solution

pH is calculated using the H⁺ concentration

pOH scale is used to determine how basic a solution is

pOH is calculated using the OH⁻ concentration

pH and pOH are related in the following formula

pH + pOH = 14

pH = 3

pOH = 14 - 3

pOH = 11

pOH is calculated using the following formula

pOH = - log[OH⁻]

[OH⁻] = antilog(-pOH)

[OH⁻] = antilog(-11)

[OH⁻] = 1 x 10⁻¹¹ M

the [OH⁻] concentration of lemon juince is D) 1 x 10⁻¹¹ M

Explain whether each of the possible reactions listed below will occur. For those that will, predict what the products will be.

Alex777 [14]

Answer:

Zn(s) + 2H₂O (l) → Zn(OH)2(aq) + H2(g)

Sn(s) + O2(g) →SnO2(s)

Cd(s) + Pb(NO3)2 (aq) →Cd(NO3)2 (aq) + Pb(s)

Cu (s) + HCl(aq) → can not occur

Explanation:

Metals reacts with liquid water to yield the corresponding metallic hydroxide and hydrogen gas as shown above; Zn(s) + 2H₂O (l) → Zn(OH)2(aq) + H2(g)

Tin reacts with oxygen to yield tin (IV) oxide. This is an oxidation reaction as shown; Sn(s) + O2(g) →SnO2(s)

The reaction between Cd and Pb(NO3)2 is a single replacement reaction. It is possible because Cd is above Pb in the electrochemical series. Hence the reaction occurs thus; Cd(s) + Pb(NO3)2 (aq) →Cd(NO3)2 (aq) + Pb(s)

Copper does not displace hydrogen from dilute acids (such as HCl) since copper is lower than hydrogen in the electrochemical series hence the reaction does not occur.
