PolarNik [594]

Answer: C. unknown element he predicted would have properties similar to those of aluminum.

Explanation: Mendeleev arranged the elements in order of increasing atomic masses. He left spaces for the elements that were predicted to exist, but were not discovered.

One space was left below Aluminum where an element of mass 70 was predicted to exist with properties similar to Aluminum. It was referred to as eka-Aluminum.

Later it was named as gallium.

What thermodynamic property describes the relationship of an equilibrium to temperature?
brilliants [131]

The thermodynamic property that describes the relationship between  equilibrium and temperature is Thermodynamic equilibrium

Thermodynamics is a science that focuses on explaining chemically and physically phenomenons related to:

  • Heat
  • Temperature
  • Energy

In thermodynamics, the thermodynamic equilibrium occurs if the temperature or heat is in balance, and therefore it will not change in regular conditions. For example:

  • If a liquid has the same temperature as its surroundings, the temperature is likely to remain stable
  • The temperature of a liquid or solid does not change unless there are specific conditions
  • According to this, thermodynamic equilibrium describes the relation of equilibrium to temperature

A 34.0 kg sled is accelerated by a constant force of 45.0 N from 2.00 m/s to 16.00 m/s. For how long was the force acting on the
goblinko [34]

Answer: 10.6 sec

Explanation:

Because I got it right on my quiz :D

also because you can use the impulse momentum formula, Ft=m(triangle)v

so basically u do 16m/s-2m/s=14m/s and thats your triangle v (change in velocity) then multiply 14 times the mass, which is 34. Thats 476, so now you have ft=476, and you know F, the force, so all you have to do is divide 476 by 45, and you get like 10.5777777 which rounds up to 10.6!
