These clouds indicate weather. as they darken, they could be a sign of question 5 options: cold; snow clear, sunny; rain hot, sunny; colder days clear, cold; warmer days

The corrects answer are cold and snow clear.

Explanation:

The clouds in the sky indicate that the weather will be cold. The dark cloudiness is because when the cloud absorbs a greater amount of water and the drops are denser, they do not allow the sunlight to filter out and are therefore perceived to be grey or black, indicating the possibility of snow.

Have a nice day!

most sediment washes or falls into the river as a result of mass movement and runoff. other sediment eroded from the bottom or sides of the river.

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g
