I’m sorry if this doesn’t help but here is what I found:
In oceanography, terrigenous sediments are those derived from the erosion of rocks on land; that is, they are derived from terrestrial (as opposed to marine) environments.
Answer:
Oxygen and Carbon dioxide
Explanation:
Oxygen is required for respiration whereby energy is released from natural occurring nutrients accompanied by the release of water and carbon dioxide. carbon dioxideis also required by plants to photosynthesise.
Oxygen and carbon dioxide in the troposphere supports life as by enabling respiration in organisms and photosynthesise in plants can. Without oxygen in an environment, only life forms that live by anaerobic respiration will thrive. This affects a regions carrying capacity
Answer:
466.65 K
Explanation:
Using the formula of Pressure law,
P/T = P'/T'.................... Equation 1
Where P = Intial pressure of gas, T = Initial temperature of gas, P' = Final pressure of gas, T' = Final temperature of gas.
make T' The subeject of equation 1
T' = (P'T)/P................... Equation 2
From the question,
Given: P = 500 Torr = (500×133.322) N/m² = 66661 N/m², T = 35°C = (35+273) = 308 K, P' = 101000 N/m²( Standard pressure)
Substitute these values into equation 2
T' = (101000×308)/66661
T' = 466.65 K
Answer:
Energy produced by the chip =10,460 Joules.
Explanation:
The specific heat of water is one calorie/gram ° C = 4.186 joules/gram ° C, which is higher than any other common substance. As a result, water plays a very important role in regulating temperature. The specific heat per gram for water is much greater than that of a metal, as described in the water-metal example. Replace the mass (m), the temperature change (ΔT), and the specific heat (c) of the solution in the equation Q = c x m x ΔT, where Q is the heat absorbed by the solution. For specific heat of water we goes as given in the question 4,184 J/kg°C
Q =4184×0.5×(25-20)
=10,460 Joules.
Thus heat gained by water (Q)= Energy produced by the chip =10,460 Joules.
Answer: Part 1: The reaction is considered as replacement reaction and produce preciptate.
Part 2: Due to Mg is more active than Al.
Explanation:
Part 1: the reaction is replacement reaction due to the ions is replaced with each other as this equation shows:
MgCl2 + Na2CO3 → MgCO3 + 2NaCl
and MgCO3 is a white precipitate.
Part 2:
Al reacts with CuCl2 because Al is more active than Cu.
Al can not react with MgCl2 because Mg is more active than Al.
