Answer:
Spring tides have higher high tides and lower low tides whereas neap tides have lower high tides and higher low tides.
Explanation:
Q = m . C . Δ T
q : Heat absorbed
m : mass of the sample
C : The specific heat of the substance.
Δ T : The change in temperature (Final T - initial T)
So:
q = 15.5 x 4.18 x (50 - 25) = 1619.75 J
Answer:
54.1 % Ca, 43.2 % O, 2.7% H
Explanation:
Molecular formula for calcium hydroxide is Ca(OH)₂
As we don't have a mass of Ca(OH)₂ to find out the percentage composition, we consider that the question refers to 1 mol of compound.
1 mol of hydroxide weighs 74.08 g
1 mol of hydroxide has 1 mol of Ca, therefore 40.08 g are Ca
2 moles of O therefore 32g are O
2 moles of H therefore 2 g are H
Percentage composition is known as (Mass of element/Total mass) . 100
- (40.08 / 74.08) . 100 = 54.1 %
- (32 / 74.08) . 100 = 43.2 %
- (2 / 74.08) . 100 = 2.7%
I would do the nervous system because nerves are what makes you feel everything around you and in order for you to be able to react you need the nervous system why? <span>The nervous system is the highway along which your brain sends and receives information and feelings about what is happening in the body and around it on the outside. This highway is made up of billions of nerve cells, or neurons which join together to make nerves. This is very important for the human to be able to live!</span>
The last statement is correct...
