Answer:
less dense
Explanation:
the reason that the density would be lower is because the air bubbles keep the maximum amount of atoms possible from being in that space. imagine pouring a glass of soda from a freshly opened bottle, at first it looks like there's a lot in the glass but as the bubbles dissipate, there's less and flat soda appears to have even less in the glass. i hope this analogy helped :)
<span>The correct answer is because there are strong adhesive forces exist between glass and the water molecules. They're not as strong as let's say glue or similar adhesives, but are good and water connected to glass has bigger adhesivity then if it was inside of a wooden cup for example or a bowl.</span>
The products are on the right side of the chemical equation, while the reactants are on the left side of the chemical equation.
Therefore if we have:
methane + oxygen → carbon dioxide + water
Then the reactants are methane + oxygen
The products are: A) Carbon dioxide + Water
To convert from L to ml, we move three spaces to the right and the decimal place moves three places.
Our task here is to convert 600 L to mL. we have to remember that to convert from L to ml, we have to multiply the value in L by 1000
In other words, the value 1000 is known as the conversion factor.
When we do this, we move the decimal place three places to the right to have 600000.00mL

Answer:
The length of the wire = 352.66 feet.
Explanation:
A copper refinery produces a copper ingot weighing 150 lb. If the copper is drawn into wire whose diameter is 9.50 mm, how many feet of copper can be obtained from the ingot? The density of copper is 8.94 g/cm3. (Assume that the wire is a cylinder whose volume is V = πr2h, where r is the radius and h is its height or length.)
Step 1: Convert lb to kg
150 lb = 68.0389 kg
Step 2: Calculate volume of copper
Volume = mass / density
Volume = 68038.9 grams / 8.94 g/cm³
Volume = 7610.6 cm³ Cu
Step 3: Calculate length of wire
The diameter of the wire is 9.50 mm, so the radius is half of that (4.75 mm), or 0.475 cm.
The total "volume" of the wire is πr²h = (π)*(0.475 cm)²(h) = 0.708h = 7610 cm^3
7610 = 0.708h
h = 10749 cm = length of wire
The length of the wire = 352.66 feet.
