Two major properties are Ductile malleable and they are good conductors
Answer:
C. The larger a molecule, the faster it will effuse.
Explanation:
The sentence C "The larger a molecule, the faster it will effuse" is false because, it is the exact opposite. When a molecule is bigger it takes longer to effuse because has more components that have to pass through that effect making it last longer tan short molecules.
Answer:
13.4g
Explanation:
we know that:
1 mole = 6.02 × 10²³ atoms
make the unknown number of moles = x
x = 7.1 × 10²² atoms
putting them both together:
1 mole = 6.02 × 10²³ atoms
x = 7.1 × 10²² atoms
Cross multiply:
6.02 × 10²³ x = 7.1 × 10²²
divide both sides by 6.02 × 10²³
we now have the number of moles of Al₂CO₃
to calculate the grams (mass):
add up all of the atomic masses of Al₂CO₃ to calculate relative formula mass:
(27 × 2) + 12 + (16 × 3) = 114
the grams (mass) of Al₂CO₃:
D. Nonpolar dissolves in polar
In this case, when converting scientific notation to standard notation, we simply have to multiply the given number by 10^{x}x.
The answer will be 7.510^{2} = 7.5100 = 750
A standard notation is a form of writing a given number, an equation, or an expression in a form that follows certain rules. For example, 4.5 billion years is written as 4,500,000,000 years.
