Answer:
Large wheel.
Explanation:
It would be easier for the captain to turn a large wheel as compared to a small wheel because less amount of effort is needed by the captain to turn the rudder. If a steering wheel is small, more effort and force is required to turn it while on the other hand, if the steering wheel is large, small effort is needed to turn the rudder. The large size of a sailing boat's steering wheel can help the captain to have more control over the boat as compared to small steering wheel and he is able to access it from either side of the boat.
First, 55 g of Hg is 3.65 moles because one mole of Hg has a molar mass of 200.59
Then, the mole ratio of Hg to CaO is 8:4 or 2:1. SO we divide 3.65 by 2 to get 1.82 moles of CaO
This is the same as 102.06 grams because one mole of CaO has a molar mass of 56.0774
Hope this helps!
Answer: The mass of produced is, 149 grams.
Explanation : Given,
Mass of = 354.2 g
Molar mass of = 278 g/mol
Molar mass of = 58.5 g/mol
First we have to calculate the moles of
Now we have to calculate the moles of
The balanced chemical equation is:
From the reaction, we conclude that
As, 3 moles of react to give 6 mole of
So, 1.27 moles of react to give mole of
Now we have to calculate the mass of
Therefore, the mass of produced is, 149 grams.
Answer:
C. 0.001 second
Explanation:
Millisecond is a subunit of a second.
Milli depicts a unit to the power of 10⁻³
So;
1 millisecond = 10⁻³ s
Therefore,
1 x 10⁻³ = 0.001s
The solution to this problem is choice C which is 0.001 second
Answer:
0.8 mL of protein solution, 9.2 mL of water
Explanation:
The dilution equation can be used to relate the concentration C₁ and volume V₁ of the stock/undiluted solution to the concentration C₂ and volume V₂ of the diluted solution:
C₁V₁ = C₂V₂
We would like to calculate the value for V₁, the volume of the inital solution that we need to dilute to make the required solution.
V₁ = (C₂V₂) / C₁ = (2mg/mL x 10mL) / (25 mg/mL) = 0.8 mL
Thus, a volume of 0.8 mL of protein solution should be diluted with enough water to bring the total volume to 10 mL. The amount of water needed is:
(10 mL - 0.8 mL) = 9.2 mL
