What can you predict about an element from its position in the periodic table

Answers

Based on its position in the periodic table, you can predict how many electrons it has, how many valence electrons, how many levels of electrons, and its atomic number and mass.

A Carnot heat engine has an efficiency of 0.400. If it operates between a deep lake with a constant temperature of 298.0k and a hot reservoir, what is the temperature of the hot reservoir?

Answers

Answer:

496.7 K

Explanation:

The efficiency of a Carnot engine is given by the equation:

\eta = 1 - (T_H)/(T_L)

where:

T_H is the temperature of the hot reservoir

T_C is the temperature of the cold reservoir

For the engine in the problem, we know that

\eta = 0.400 is the efficiency

T_C = 298.0 K is the temperature of the cold reservoir

Solving for T_H, we find:

(T_C)/(T_H)=1-\eta\nT_H = (T_C)/(1-\eta) =(298.0)/(1-0.400)=496.7 K

Volume , mass, and weight can be measured with balances, scales, and ?

Answers


If you are talking about volume, then an easy way to measured the volume of a liquid would be with a graduated cylinder. A graduated cylinder is marked with volume units such as milliliter (mL) or the liter (L). One liter equals 1 thousand milliliters.

To measure the volume of a solid you use the formula V = (Length)(Width)(Height)

To measure the volume of a gas you use a graduated cylinder held upside down. At first the cylinder is filled with water. When air is blown into the cylinder, bubbles rise and push some water down. The volume of the water pushed down is equal to the volume of the gas that was blown in.

Imagine that a brown horse and a white horse cross to produce offspring whose coat is made up of some brown hair and some white hairs. Which pattern of dominance is this an example of this

Answers

Answer:

Codominace

Explanation:

Codominance simply refers to a situation whereby there is an equal genetic effect of two parents on their offspring. It is a situation whereby neither of the alleles (i.e. a variant or type of gene) of the two parents can dominate, mask or prevent the expression of the other. Consequently, this will result on the equal expression of the two alleles for trait of the two parents.

Using the human example, there is a codominance when there is the ABO blood group which permits both alleles A and B to be expressed. As a result, if alleles A is inherited by a child from his father and he inherited allele B from his mother, it will result in him having AB as his blood type.

Therefore, the pattern of dominance is the example given in the question is called "codominance."

This is an example of Co dominance.

HELP!!!!!! PLEASE!! I WILL GIVE 25 POINTS!!!!1) Joe and Ben were arguing about the Law of Conservation of Energy. Joe said that the Law of Conservation of Energy must be false because when you turn on a light it uses energy and so some of the energy is lost. Ben disagrees and says that energy cannot be created or destroyed. Who is right? Justify your answer.A) Joe is right because the electricity is changed to heat and light and is no longer electricity.B)Ben is right because the Law of Conservation of Energy is a law and cannot be false.C) Ben is right because the electricity from the light is transformed into heat and light.D) Joe is right because all electrical lights and appliances use electricity.2) Greg and Shawn are studying for a physical science test. Greg thinks that the kinetic energy of an object depends on the height and speed of an object, but Shawn thinks it depends on the mass of an object. Who is right and why?A) Shawn is right. The mass of an object determines the inertia of the object. Increasing inertia is the only thing that will increase kinetic energy.. B) Both Greg and Shawn are correct since kinetic energy depends on mass, height and speed of an object.C) Greg is right. Increasing the height or speed of an object increases the kinetic energy of an object.D) Neither is completely right. Shawn is partly correct since kinetic energy depends on mass, but Greg is also partly right since it also depends on speed.3) Dan got into his car in the middle of summer. When he sat on the hot black leather seats, he burned his legs. His sister said that conduction was the reason Dan burned his legs, but Dan blamed the sunshine and said it was radiation that caused him to get burned. Who was right and why?A) Both Dan and his sister are right. The sun heated the car seats through radiation heat transfer, but then Dan touched the seat and the heat was conducted to his legs.B) Dan's sister was correct because Dan's legs touched the car seats. That is an indicator of heat transfer by conduction.C) Dan was right because the sun heated the car without touching it. That is radiation.D) Dan's sister was right because conduction can transfer heat through both solids and fluids (such as air).
