Where on the periodic table is a metal element most likely found? Do not think about the stair case split.

Chemistry
1 answer:
rjkz [21]2 years ago
4 0

Answer:

C.) Middle

Explanation:

A.) is incorrect because elements on the bottom of the periodic table can be metals, nonmetals, or metalloids. However, the majority of these elements would be metals.

B.) is incorrect because elements on the right side (aka. the p-block) of the periodic table are mostly nonmetals. This excluding the stair case elements which are metalloids and elements to the left of the stair case which are metals.

C.) is correct because elements located in the middle of the periodic table (aka. the d-block) are always metals. The elements in this section are usually nicknamed the "transition metals". It should be noted that elements on the left side (aka. the s-block) of the periodic table are also metals (excluding hydrogen).

If the volume of a cylinder is reduced from 8.0 liters to 4.0 liters, the pressure of the gas in the cylinder will change from 7
Elza [17]

Answer:

P₂ = 140 KPa

Explanation:

Given data:

Initial volume = 8.0 L

Final volume = 4.0 L

Initial pressure = 70 KPa

Final pressure = ?

Solution:

According to Boyle's law

P₁V₁ = P₂V₂

P₂ = P₁V₁  / V₂

P₂ = 70 KPa ×8.0 L/4.0 L

P₂ = 560 KPa .L / 4.0 L

P₂ = 140 KPa

Glycolysis is the process by which energy is harvested from glucose by living things. Several of the reactions of glycolysis are
sertanlavr [38]

Answer:

Reaction A and B are unfavorable.

Explanation:

Gibbs free energy is an energy which that can be use to convert into useful work.

ΔG°=ΔH°-TΔS°

ΔG°= Gibbs free energy

ΔH° =  enthalpy of reaction

T = temperature of eh reaction

ΔS° = Entropy change

  • If the Gibbs  free energy of the reaction is positive than the reaction will be non spontaneous and the chemical reaction will be not feasible.
  • If the Gibbs  free energy of the reaction is negative than the reaction will be spontaneous and the chemical reaction will be feasible .

According to given information in the question:

Reaction A and B are non spontaneous as their Gibbs free energy value is positive.hence both are unfavorable.

Given two objects in space, the object with the ____ mass will orbit the object with the ____ mass.
Furkat [3]

Answer:

A. Smaller, Larger

Explanation:

Every object that has mass obeys the Law of Universal Gravitation. Everything attracts everything else. The same gravity that keeps us down on the ground keeps planets in orbit. However, in space, the smaller object will feel the pull of the larger one much more strongly, which is why it will begin to orbit it
