Machines are systems that are built to carry out a certain function or work. These are classified as: Simple and Compound Machines.
Simple machines are simple tools used to accomplish a certain task. These include lever, pulley, inclined plane atc. In contrast compound machines are a combination of simple machines.
In the given scenario, a pulley system was used to carry the wood from the bottom to the tree top. This is a movable pulley system which is directly attached to the load and works by decreasing the input force but not the direction.
In a neutral compound, the charges must balance, the net
charge should be zero.
Since the charge of Fe is 3+ and that of O is 2-, therefore,
there should be 2 Fe 3+ ions per 3 O2- ions in order to have a net charge of
zero.
Answer:
The detailed calculation is shown in the attached file.
last condition (1000 K in 150.000 dm3) will have the least deviations and it is the condition where real gas will behave as ideal gases
Explanation:
Real gas behave more ideally or they tend towards ideality when there is the least deviation, or their inter-molecular forces between their molecules are mainly responsible for their deviations as such gases with the strongest intermolecular forces shows the strongest deviations. As such, when their is an increase in temperature and volume and a decrease in pressure, real gas tends towards ideal gas in this case.
From the three conditions given, it is obvious that the last condition(1000 K in 150.000 dm3) will have the least deviations.
Answer:
Explanation:
Filteration plant for water and supply filtered hygienic water to all ...
Answer:
223.5 g
Explanation:
The formula between the number of moles, mass and Mr can be used to convert moles to grams.
<em>Number of moles = mass ÷ Mr</em>
So, mass = number of moles × Mr
Mr of Li₂O = (6.9 × 2) + 16 = 29.8
∴ Mass = 7.5 × 29.8 = <u>223.5 g</u>
