Answer:
exist in fixed amounts
Explanation:
The only attribute that describes nonrenewable resources is the <u>existence in fixed amounts.</u>
Nonrenewable resources are limited in amount and depleted at a much faster rate than they are naturally replaced. Even when they are to be replaced, it cannot be done within a short period.
<em>An example is crude oil which exists as natural deposits deep in the ground. The world's crude oil deposit is limited and cannot be replaced at a rate they are being used by man if at all it can be replaced. </em>
Answer:
D. The electron moved up to an energy level and has an energy of 21.72 x 10−19 J.
Answer: c.
Electrons are transferred → Ions form → Ions are attracted to each other
have a great day
Explanation:
First let us compute for the number of moles of butane
(molar mass = 58.12 g/mol)
number of moles = 145 g / (58.12 g/mol) = 2.49 mol
<span>We use the ideal
gas equation to calculate the volume:</span>
<span> V = n R T / P</span>
V = 2.49 mol * 62.36367 L torr / mol K * 308.15 K / 745
torr
<span>V = 64.35 L</span>
Suspensions
Explanation:
Suspensions are heterogeneous mixtures that contains large particles that can settle out or be filtered.
- Suspensions are mixtures of small insoluble particles of a solid in a liquid or gas.
- Examples are:
- powdered chalk in water
- muddy water
- harmattan
The particles in suspension can settle on standing
