Answer:
B. The theory might be modified if necessary.
B. nearly all scientists agree that it is correct
Explanation:
B. The theory might be modified if necessary.
The Bernoulli's principle relates the speed of fluid to their pressures. It simply states that when the speed of fluids increases there is a drop in pressure.
Supposing we find new evidence about how the principle works, the normal scientific thing to do is to modify the existing principle. New information and observations about a principle would only provide a modification to the existing one. An example is the Dalton's atomic theory, which was centered on the atom being the smallest indivisible particle: the theory was later modified when new ideas about the atom surface.
B. nearly all scientists agree that it is correct
Before a hypothesis is adopted to the context of scientific principle, the ideas behind it must have tested and must be repeatable. Different sources will verify the authenticity of such scientific claim to see if such can be adopted. Therefroe, nearly a large numbr of scientists must agree that it is correct.
Answer:
the weight of products is is equal the weight of the wood plus the weight of oxygen that was used to burn that wood, so weigh of the product is greater than 10 kilograms.
Explanation:
Conservation of mass (mass is never lost or gained in chemical reactions), during chemical reaction no particles are created or destroyed, the atoms are rearranged from the reactants to the products.
In this example wood (mostly carbon) and oxygen are reactants and carbon dioxide (mostly) is product of reaction.
I don't know what model you're referring to so I can't answer the question. However, upon researching, I found a similar problem. I posted it as an attached picture. Looking at the model, the amount of grams a herbivore eat each day corresponds to the arrow pointing inwards. Since the label says 4.0 g,
<em>the answer is 4 g per day</em>.
They have a mass for the particles
There are no totally elastic collisions
There are intermolecular forces
Answer:
38 L
Explanation:
There is some info missing. I think this is the original question.
<em>Consider the chemical reaction: C(s) + H₂
O(g) ⟶ CO(g) + H₂
(g). How many liters of hydrogen gas is formed from the complete reaction of 15.2 g C? Assume that the hydrogen gas is collected at a pressure of 1.0 atm and a temperature of 360 K.</em>
<em />
Step 1: Write the balanced equation
C(s) + H₂
O(g) ⟶ CO(g) + H₂
(g)
Step 2: Calculate the moles corresponding to 15.2 g of C
The molar mass of C is 12.01 g/mol.
Step 3: Calculate the moles of H₂ produced from 1.27 moles of C
The molar ratio of H₂ to C is 1:1. The moles of H₂ produced are 1/1 × 1.27 mol = 1.27 mol.
Step 4: Calculate the volume of H₂
We will use the ideal gas equation.
