Answer:
Below
Nitric acid
Lead
Sodium nitrate
Explanation:
The activity series is an arrangement of metals in order of decreasing reactivity. Metals that are higher up in the series displace metals that are lower in the series from dilute solutions. Hence, when the ion of a metal that is lower in the series reacts with a metal that is higher up in the series, the latter is oxidized.
Dilute acids dissolve metals above hydrogen in the activity series such as as zinc and lead. Platinum is much lower than sodium in the activity series hence platinum does not react with sodium nitrate.
Hard question thx for the points
Oxygen is a liquid under one atmosphere. the boiling point of a substance is the temperature at which vapor pressure of a liquid is equal to the pressure of the surrounding liquid. the boiling point of oxygen at this case is 90.0k. Therefore the temperature of oxygen is 90-273= -183 celsius scale
Answer:
One quart.
Explanation:
Let us consider the relation between all of the given units of volume and one litre.
a) one litre equals to 33.84 ounces
b) one litre equals to 2.11 pint
c) one litre equals to 0.95 quart
d) one litre equals to 4.54 gallons
Thus from above conversions it is clear that one litre is almost equal to or about 1 quart (0.95 approxes 1).
The correct answer is (D)
All the above are reasons the carbon , oxygen, and nitrogen cycles are vital to life on earth.
The explanation:
because :
1) Carbon, oxygen, and nitrogen are vital components of life on Earth.
2) The carbon, oxygen, and nitrogen cycles allow vital elements to return to usable form by organisms.
3)The carbon, oxygen, and nitrogen cycles are an important interface between biotic and abiotic factors
4) They are all biogeochemical cycles.
5) They all involve an interaction between living and nonliving elements.
6)They are all part of the Earth system.
