Answer:
A)Hydrogen can be stored physically as either a gas or a liquid. Storage of hydrogen as a gas typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure). Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is −252.8°C.
B) carrying capacity of the lithium reserve will reach 10 million EV and 90 billion CE's RLBs for 50% recycling of lithium-containing waste, and 15 million EV and 150 billion CE's RLBs for 90% recycling.

How many moles of NH3 are produced when 0.60 mol of nitrogen reacts with hydrogen in N2 + 3H2 ----> 2NH3
Answer:
0.80 mol
Explanation:
n(H)/n(N) = 1/3
n(N) = 3×0.60
n(N) = 1.8 mol
n(N) in excess = 1.80-0.60 = 1.20 mol
n(N)/n(NH3) = 3/2
n(NH3) = 2/3×1.20 = 0.80 mol
2 CH3Oh + 3O2 + 2CO2 + 4 H2O how many liters of carbon dioxide will be formed form 6 moles of oxygen
Answer:
89.6 L of CO₂
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
2CH₃OH + 3O₂ —> 2CO₂ + 4H₂O
From the balanced equation above,
3 moles of O₂ reacted to produce 2 moles CO₂.
Next, we shall determine the number of mole CO₂ produced by the reaction of 6 moles of O₂. This can be obtained as follow:
From the balanced equation above,
3 moles of O₂ reacted to produce 2 moles CO₂.
Therefore, 6 moles of O₂ will react to produce = (6 × 2)/3 = 4 moles CO₂.
Thus, 4 moles CO₂ were obtained from the reaction.
Finally, we shall determine the volume occupied by 4 moles CO₂. This can be obtained as follow:
1 mole of CO₂ occupied 22.4 L.
Therefore, 4 moles CO₂ will occupy = 4 × 22.4 = 89.6 L
Thus, 89.6 L of CO₂ were obtained from the reaction.
Given 2.0 moles of nitrogen and plenty of hydrogen, how many moles of NH3 are formed?

How many liters of oxygen are needed to burn 2.76 L of carbon monoxide?
Answer: 1,38 litres
Explanation: it should be 2 CO + O2 ⇒ 2 CO2
In Same temperature volumes are proportional
To amounts of substances. So amount of Oxygen is half of
Amount of CO
Answer: 1.38 L O2
Explanation:
2CO + O2 = 2CO2
So,
1 mole CO = 22.4 L CO
2 mole CO = (22.4 ×2)L CO
= 44.8 L CO
And 1 mole O2 = 22.4 L O2
44.8LCO are burned by 22.4LO2 1 L CO are burned by 22.4÷ 44.8
= 0.5 L O2
2.76L CO are burned by0.5×2.76
= 1.38 L O2
So, 1.38 L O2 are needed to burn
2.76 L CO

Which example describes how the water cycle carries on energy transfer? a flooding river depositing silt on a floodplain a warm ocean current warming the air above it ocean water depositing sand particles on a shore water seeping through the soil and dissolving salts
Answer:
The water cycle is driven primarily by the energy from the sun. This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.
In an ecosystem, the water cycle carrying on energy transfer is best exhibited the example of a warm ocean current warming the air above it .
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

what is the equivalent weight of sodium trioxocarbonate (IV) in the reaction between Hydrochloric acid and sodium trioxocarbonate (IV)?
Correct answer gets brainliest. This is urgent.
Answer:
Standard acid-base reaction in two stages:
Na2CO3 + HCl → NaHCO3 +NaCl
NaHCO3 + HCl → NaCl + CO2 + H2O
If only a small quantity of acid is added (and the overall solution remains above pH 7), the reaction would stop at stage 1 and you’d be left with an aqueous solution of sodium chloride and sodium bicarbonate. Adding more acid would lead to the bicarbonate being converted to carbon dioxide and water, with the CO2 coming out of solution as a gas and more sodium chloride being produced.
