Answer:
m AgCl = 28.395 g
Explanation:
- AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq)
∴ [AgNO3] = 0.156 mol/L
∴ V = 1.27L
⇒ mol AgNO3 = 0.156 mol/L * 1.27 L = 0.19812 mol AgNO3
mass AgCL:
⇒ m AgCl = 0.19812 mol AgNO3 * mol AgCl/molAgNO3 * 143.32gAgCl/molAgCl
⇒ m AgCl = 28.395 g
Answer:
NaCl
Explanation:
none of them. Salt presents NaCl
Answer:
Okay here's the answer ↓
Step-by-step explanation:
Tropical climate is one of the five major climate groups in the Köppen climate classification. Tropical climates are characterized by monthly average temperatures of 18 ℃ (64.4 ℉) or higher year-round and feature hot temperatures. Annual precipitation is often abundant in tropical climates, and shows a seasonal rhythm to varying degrees. There are normally only two seasons in tropical climates, a wet season and a dry season. The annual temperature range in tropical climates is normally very small. Sunlight is intense because they are receiving direct sunlight.
Answer:
Directly
Explanation:
If V increases, then T must also increase to keep the same ratio.
If V decreases, then T must also decrease to keep the same ratio.
V and T are directly proportional, because a change in one always causes a change in the other and the changes are in the same ratio. The constant k is called the proportionality constant.
Answer : The frequency of a photon of radiation is, 
Explanation : Given,
Wavelength of the radiation = 670.8 nm
First we have to convert wavelength form 'nm' to 'm'.
Conversion used : 
So, the wavelength of the radiation = 670.8 nm = 
Now we have to calculate the frequency of a photon of radiation.
Formula used : 
where,
= frequency of a photon of radiation
= wavelength of the radiation
c = speed of light = 
Now put all the given values in the above formula, we get the frequency of a photon of radiation.
Therefore, the frequency of a photon of radiation is,
